QUESTION

Symfony 4.4 Auth0 how to completely logout user from the application

Asked 2021-Aug-26 at 06:58

Basic info:

I created a test application to test if SSO (Single sign on) works. I use Auth0 as a SSO provider. Symfony 4.4 as application framework. I used this article from Auth0 to create the basics. So far I can login/logout.

Problem:

When I login once (with credentials), logout after and then login again I am instandly logged in with the same account I used before. Without needing to fill in credentials again. It seems to remember the session or somehow does not completely logout a user. I want the user to have to login again with credentials after it logged out. Since some of my users will use one computer for the applications (so switching user is needed).

Possible fix/Extra info:

According to there docs/community I should look at this. But this seems to mean that I need API calls to add the ?federated. Which the setup example does not use (probably the library does it for me). Also my logout function in the SecurityController that is generated by the make:auth (or make:user) doesn't execute the code anymore. Even if I change the function name it still logged me out. Only untill I remove/change the route name it stops. It's probably very bad but maybe if I had the chance to execute a API call when I logout I could do this API call.

The best thing I could imagine to do is change some settings in symfony or add some small piece of code to make it logout correclty. But I dont know how.

My code:

SecurityController.php

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils;

class SecurityController extends AbstractController
{
    /**
     * @Route("/login", name="app_login")
     */
    public function login(AuthenticationUtils $authenticationUtils): Response
    {
        // get the login error if there is one
        $error = $authenticationUtils->getLastAuthenticationError();

        // last username entered by the user
        $lastUsername = $authenticationUtils->getLastUsername();

        return $this->render('security/login.html.twig', ['last_username' => $lastUsername, 'error' => $error]);
    }

    /**
     * @Route("/logout", name="app_logout")
     */
    public function logout()
    {
        // Does not trigger at all. It does not stop the page but just continues to redirect and logout.
        dump($this->get('session'));
        dump($session);
        dump("test");
        exit();
        throw new \Exception('This method can be blank - it will be intercepted by the logout key on your firewall');
    }
}

It looks like that you have to logout from the oauth service you are using, here is a similar issue.

Worked out in code:

src/Security/CustomLogoutSuccessHandler.php

<?php

namespace App\Security;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Security\Http\Logout\LogoutSuccessHandlerInterface;

class CustomLogoutSuccessHandler implements LogoutSuccessHandlerInterface
{
    private $target;

    public function __construct(string $target)
    {
        $this->target = $target;
    }

    public function onLogoutSuccess(Request $request)
    {
        return new RedirectResponse($this->target);
    }
}

security.yaml

logout:
   path: /logout
   success_handler: App\Security\CustomLogoutSuccessHandler

services.yaml

services:
   App\Security\CustomLogoutSuccessHandler:
       arguments: ['%env(resolve:LOGOUT_TARGET_URL)%']

.env

LOGOUT_TARGET_URL=https://{yourAuth0AppDomain}.auth0.com/v2/logout?returnTo={yourRedirectURL}&client_id={secret}

Using code from the Github issue redirects you 4 times. Logout->Route->(.env)Auth0->Route.

Using code shown above redirects you 3 times. Logout->Auth0->Route. Just a small improvement.

Code from this post.

QUESTION

How to use async await in React components without useEffect

Asked 2021-Aug-05 at 10:23

My app has a search bar where the user types in a word and clicks search. Upon click, the app fetches the definition of that word from an open dictionary API, and then updates the parent component's state to reflect the results. The component is then supposed to render the results by passing that as a prop to a presentational child component.

However, it looks like the state gets set before the fetch call has the time to return the data. So the search results are not rendered until the search button is clicked again, causing confusion.

I have tried resolving this by making my function asynchronous (Dictionary.search refers to an imported function which handles the fetch and returns the result in the form of an array):

async search(term) {
    const results = await Dictionary.search(term);
    this.setState({ searchTerm: term, results: results });
  }

However this only works some of the time. For longer searches, it doesn't wait before updating the state and re-rendering.

I have done some googling and came across this suggestion, but it also doesn't work:

search = (term) => {
    const dictionarySearch = async (term) => {
      const results = await Dictionary.search(term);
      this.setState({ searchTerm: term, results: results });
    };
    dictionarySearch(term);
};

EDITED TO ADD: Here is the Dictionary.search code, along with its helper function:

//Create an empty array in which the results of the API call will be stored
let results = [];

const Dictionary = {
  search(term) {
    //Url with our search term and API key:
    const url = `https://www.dictionaryapi.com/api/v3/references/collegiate/json/${term}?key=${api_key}`;

    //Fetch the results from Merriam Webster API:
    fetch(url)
      .then((response) => {
        //Catch an error from their server
        if (!response.ok) {
          throw new Error("Network response was not ok");
        }
        //Return javaScript object version of the response
        return response.json();
      })
      .then((jsonResponse) => {
        //Perform the helper function on the javascript object and return the result (array)
        return shortDef(jsonResponse);
      })
      //Catch any other errors than a server error
      .catch((error) => {
        console.error(
          "There has been a problem with your fetch operation:",
          error

I don't want to call the API in the ComponentDidMount, because it should get called every time the user presses "search". I also would prefer not to use useEffect, as it would mean refactoring my entire component from a class to a function.

Is there no way to have the setState in a class component wait for an asynchronous task to complete?

ANSWER

Answered 2021-Aug-05 at 08:07

The problem is that your Dictionary.search function immediately returns, because it does not wait until the .then block resolves. Change it to an async function and await the fetch of the url. It should look like this:

const Dictionary = {
  // Make search an async function
  search: async term => {
    const url = `https://www.dictionaryapi.com/api/v3/references/collegiate/json/${term}?key=${api_key}`;

    // Await the results
    await fetch(url)
      .then(response => {
        // ...
      })
      .then(jsonResponse => {
        // ...
      })
      .catch(error => {
        // ...
      });

    return;
  },

No, it's not good practice. In case of bare-metal MCU programming, then re-entrancy isn't an issue - which would otherwise be a strong argument against code like this. But the main issue is that you are breaking private encapsulation by exposing a read/write variable to the caller. Which contains function pointer members no less. That's a dangerous and brittle interface.

You cast to const before returning which improves the situation a lot. This is still read/write RAM but the caller shouldn't modify it unless they do something weird like casting away const. The question is why you didn't make these variables static const to begin with though? Then they would also end up in flash and not sit in your valuable RAM. It's literally waste of space.

Serializing List of Json Objects with Newtonsoft results in incorrect formatting with many "\r\n"

Asked 2021-Mar-26 at 18:25

Below is a snippet of my code:

private void Save(object sender, EventArgs e)
        {
            var readText = File.ReadAllText(FilePath);

            JObject jsonObject = JsonConvert.DeserializeObject(readText) as JObject;
            string cfgStr = JsonConvert.SerializeObject(ListViewContents, Formatting.Indented);
            jsonObject["JoystickName"]["input_bindings"] = cfgStr;

            File.WriteAllText(FilePath, jsonObject.ToString());
            Navigation.PushAsync(new MainPage());
        }

I am trying to serialize a list of json objects, ListViewContents is a list of objects as each input binding can be different. When I serialize the list and write to the file, it writes all of the input bindings on one line with this as an output:

"input_bindings": "[\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.cableCutCover\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Down\",\r\n    \"invert\": true\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.cableCut\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Left\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.winchArmSwitch\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Right\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.bottomRight\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"L3\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.topLeft\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"Select\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.mic_en\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"Start\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.hot_mic_en\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"R3\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.wog_present\",\r\n    \"input_type\": \"button\",\r\n    \"output_type\": \"boolean\",\r\n    \"button_id\": \"DPad Up\"\r\n  },\r\n  {\r\n    \"topic\": \"hwi.te0_ptt_wog.winchCommand\",\r\n    \"input_type\": \"axis\",\r\n    \"output_type\": \"analog\",\r\n    \"axis_id\": \"Trigger Left\",\r\n    \"scalar\": -1.0,\r\n    \"bias\": 0.0\r\n  }\r\n]"

Ideally, the entire JSON file looks like this:

}

Once I assign "input_bindings" to cfgStr, this strange formatting occurs.

Any help would be greatly appreciated, and I was unable to find any posts similar to my problem while searching.

ANSWER

Answered 2021-Mar-26 at 18:17

This is the problem:

string cfgStr = JsonConvert.SerializeObject(ListViewContents, Formatting.Indented);
jsonObject[JoystickName]["input_bindings"] = cfgStr;

You're setting the value of input_bindings to "the result of serializing JSON" (i.e. a string). You're then serializing the whole object (with jsonObject.ToString()), so that serializes that string, including escaping everything. You only want to serialize once.

I suspect you just want:

jsonObject[JoystickName]["input_bindings"] = JArray.FromObject(ListViewContents);

In other words, convert ListViewContents into the LINQ to JSON model, but don't serialize it as a string yet.

ANSWER

Answered 2021-Feb-09 at 16:30

This is a JS object contained in an array, referencing the Array[0] will target the JS object. For example,

let theArray = [{1, 2, 3}]
let theObject = theArray[0]

A try...catch statement would help you to handle the errors if it works well when the value exists. The following would only get the value if no error exceptions are thrown.

tags = []
for (let i = 0; i < data.length; i++) {
  try { 
    let captured = data[i].hwi.prs.sound.audio
    tags.append(captured)
  } catch {
    console.log('No values found')
  }

How to deal with different JSON Response in Spring

Your “normal” response isn’t valid JSON, but that aside, here’s what you can do. Get the response content as a string with bodyToMono(String.class). Then read the response as a JSON tree

JsonNode root = mapper.readTree(jsonString)
if (root.isArray())
    // deserialize into a list
else
    // deserialize into the meta structure

You can convert a JsonNode to an object using mapper.treeToValue.

QUESTION

finding duplicates in a dictionary

Asked 2020-Nov-12 at 02:13

I have a list of dictionaries like:

regReads=[{'QNAME': 'HWI-ST1024_0272:8:2105:10935:58524', 'FLAG': 16, 'RNAME': 'chr2', 'POS': 143138210, 'MAPQ': 42, 'CIGAR': '50M', 'RNEXT': '*', 'PNEXT': 0, 'TLEN': 0, 'SEQ': 'GAGGTCCAAACTTTAAATACTCAGAAGGATTTCTGAACTAGTTCTCTGTG', 'QUAL': 'JIJJIJJJJIGGBIIIHBCHEJIJJIIJIIJJIJIIHHDFHDDDBFFCC@'}, 
{'QNAME': 'HWI-ST1024_0272:8:1106:21049:70180', 'FLAG': 0, 'RNAME': 'chr2', 'POS': 143070473, 'MAPQ': 42, 'CIGAR': '50M', 'RNEXT': '*', 'PNEXT': 0, 'TLEN': 0, 'SEQ': 'AGGGTGACCAACTTATTCCTATTTTTCTAAGACTTTCCCCATTTTAGCAC', 'QUAL': '@CCFDDFFHHHHHJJJJJJJJJJJJJIJJJJJJJJJJJJJJIJJJIJIGI'}, 
{'QNAME': 'HWI-ST1024_0272:8:1101:7474:56141', 'FLAG': 0, 'RNAME': 'chr2', 'POS': 143045262, 'MAPQ': 42, 'CIGAR': '50M', 'RNEXT': '*', 'PNEXT': 0, 'TLEN': 0, 'SEQ': 'TTTAGCCTCCATTTCTGATTCAATCACCCAAGACAGCAGACTCAGAGTTG', 'QUAL': 'CCCFFFFFHHHHHJJJJJJJJJJJJJJJJJJJIJJJJJIJJJJJJJJFIH'}]

I need to find duplicate reads and remove all but one from the list. Since I can't just do "if read not in uniqueReads" (each QNAME value is unique), I was trying to do something like this, but I think I'm over-complicating this problem.

for read in regReads:
        compareReads.append((read['POS'],len(read['SEQ']),read['FLAG']))
    n=0
    duplicates={}
    singles=[]
    addThese=[]
    for comp in compareReads:
        if compareReads.count(comp) == 1:
            uniqueReads.append(regReads[n])
        dups=[n]
        if compareReads.count(comp) != 1:
            p=0
            for alt in compareReads:
                if comp == alt:
                    dups.append(p)
                p+=1
            duplicates[n]=sorted(dups)
        n+=1
    for dup in duplicates:
        if duplicates[dups] not in singles:
            singles.append(tuple(duplicates[dup]))
            addThese.append(dup)
    for i in addThese:
        uniqueReads.append(regReads[i])
    uniqueReadCnt=len(uniqueReads)
    print(uniqueReadCnt)

I just need to compare the 3 values of each dictionary (POS, FLAG, and len(SEQ)). Is there a simpler way in Python to check all entries in the list before making a decision, and then only adding that one instance from the list? I can't think of a better way to essentially "mark" the downstream duplicate reads as invalid so that they aren't add to my list of unique reads.

For the code that I currently have, I can't figure out how to move the value into the list of "singles" as a tuple (or a nested list? I'm not sure), and then check the values of each duplicates key against that.

ANSWER

Answered 2020-Nov-12 at 00:38

You can use tuples as dictionary keys in Python:

seen = {}
for read in regReads:
    key = (read['POS'],len(read['SEQ']),read['FLAG'])
    if key not in seen:
        # first time seeing this key
        seen[key] = read
# seen.values() now contains all unique entries according to the key

Now, I am consuming this API in Google Sheets using the script ImportJSON.

Problem is, I am not able to access the def->sseq->dt->t - Mom usually acts as {it}umpire{/it} in our frequent squabbles over the sailboat.

This is the call i am making,

=ImportJSON(CONCATENATE("https://dictionaryapi.com/api/v3/references/ithesaurus/json/"&$A4&"?key=<KEY>"), "/def/sseq/dt/t", "noHeaders")

EDIT

I have already accessed,

/shortdef

/meta/syns

/meta/ants

/fl

And trying to access,

def->sseq->dt->t - Mom usually acts as {it}umpire{/it} in our frequent squabbles over the sailboat.

How can i access the said string?

ANSWER

Answered 2020-Oct-23 at 00:35

I believe your goal as follows.

You want to retrieve the value of Mom usually acts as {it}umpire{/it} in our frequent squabbles over the sailboat. from def[0].sseq[0][0][1].dt[1][1][0].t.

Unfortunately, I couldn't find the method for directly retrieving the value you expect using ImportJson. So in this answer, I would like to propose 2 patterns of scripts for retrieving the value using Google Apps Script.

Pattern 1:

In this pattern, a recursive function is used for retrieving the value. When you use this script, please put =SAMPLE1(CONCATENATE("https://dictionaryapi.com/api/v3/references/ithesaurus/json/"&$A4&"?key=<KEY>")) to a cell.

Sample script:

function SAMPLE1(url) {
  var res = UrlFetchApp.fetch(url, {muteHttpExceptions: true});
  if (res.getResponseCode() != 200) return res.getContentText();

  const getValues = (data, contents = []) => {
    for (let key in data) {
      if (key === "t") contents.push(data[key]);
      if (typeof data[key] === "object") getValues(data[key], contents);
    }
    return contents;
  }

  return getValues(JSON.parse(res.getContentText()));
}

Pattern 2:

In this pattern, JSON.parse is used for retrieving the value. When you use this script, please put =SAMPLE2(CONCATENATE("https://dictionaryapi.com/api/v3/references/ithesaurus/json/"&$A4&"?key=<KEY>")) to a cell.

Sample script:

function SAMPLE2(url) {
  var res = UrlFetchApp.fetch(url, {muteHttpExceptions: true});
  if (res.getResponseCode() != 200) return res.getContentText();
  
  var value = [];
  JSON.parse(res.getContentText(), (k, v) => {
    if (k == "t") value.push(v);
  });
  return value;
}

Note:

In these sample scripts, the response value from the URL is the JSON object in your question.
In these sample script, when there are multiple values of t in the object, those are retrieved. Pleaes be careful this.

How can I extract specific JSON elements with PHP?

I'm toying with a small program that can pass a list of words to the Merriam-Webster API, and gets returned the definition, part of speech, sample sentence and so on.

The JSON string returned for each word by the API is as follows:

                                    [
                                        "vis",
                                        [

                                        ]

            }
        ],
        "shortdef": ["a container that is used for holding flowers or for decoration"]
    }
]

The code I'm using to pull the information from the API is as follows:

<?php

$handle = fopen("inputfile.txt", "r");
if ($handle)
{
    while (($line = fgets($handle)) !== false)
    {
        // process the line read.
        //$json_new = grab_json_definition(trim($line), "collegiate", "0f3ee238-c219-472d-9079-df5ec8c0eb7d");
        $json_new = grab_json_definition(trim($line) , "learners", "d300a82d-1f00-4f09-ac62-7ab37be796e8");

        $data = json_decode($json_new, true);

        echo "Word: " . $data[0]['meta']['id'] . "<br/>";
        echo "IPA: " . $data[0]['hwi']['prs'][0][ipa] . "<br/>";
        echo "Part of Speech: " . $data[0]['fl'] . "<br/>";

        echo "Definition: " . $data[0]['shortdef'][0] . "<br/>";
        echo "Sentence: " . $data[0]['def'][0]['sseq'][0][0][0] . "<br/>";

    }

    fclose($handle);
}
else
{
    // error opening the file.
    
}



function grab_json_definition($word, $ref, $key)
{
    $uri = "https://www.dictionaryapi.com/api/v3/references/" . urlencode($ref) . "/json/" . urlencode($word) . "?key=" . urlencode($key);

    return file_get_contents($uri);

};

?>

I can easily navigate through to get the Word, Definition and so on, but I can't navigate down to "t" to get the sample sentences. I'm sure it's something basic but I can't figure it out. Any help would be appreciated.

Answered 2020-Aug-25 at 16:50

First, your JSON example is broken, I believe it is missing a [ in the beginning.

Now, Here is an example, where I load the contents of the file, json_decode your SINGLE example. Note that I am not adding a foreach loop or while loop, but I am getting all of the attributes you are aiming for:

<?php
$f = file_get_contents('inputfile.txt');
$data = json_decode($f);
print_r($data);

    echo "Word: " . $data[0]->meta->id . "<br/>";
    echo "IPA: " . $data[0]->hwi->prs[0]->ipa . "<br/>";
    echo "Part of Speech: " . $data[0]->fl . "<br/>";

    echo "Definition: " . $data[0]->shortdef[0] . "<br/>";
    echo "Sentence: " . $data[0]->def[0]->sseq[0][0][0] . "<br/>";
    echo "T1: " . $data[0]->def[0]->sseq[0][0][1]->dt[1][1][0]->t . "<br/>"; // those can also be in foreach loop, I am just showing the basic example of accessing the attributes
    echo "T2: " . $data[0]->def[0]->sseq[0][0][1]->dt[1][1][1]->t . "<br/>";

You can extend this code, or modify yours to add while/foreach loops... as you need them..

QUESTION

Passing props to state in top level component

Asked 2020-Jul-17 at 06:47

I'm trying to pass props using the handleUpdate function in my child component to my top level component and update the state with those props values. So far, I don't see the props appearing when I console log. I don't think I'm passing the correct arguments. I've tinkered around and am stuck. Can someone assist and explain their reasoning?

handleUpdate function in child component:

search = async (word) => {

        try{
            // var word = this.state.word.trim();
            const data = await MerriamAPI.getWordInfo(word);
            
            if (data){
                this.props.handleUpdate({
                    word: word,
                    info: data,
                    versions: data[0].meta.stems,
                    shortdef: data[0].shortdef[0],
                    partOfSpeech: data[0].fl,
                    pronunciation: data[0].hwi.prs[0].mw, 
                }, 
            }
            else{
                console.log('No Definition Found')
            }
        }
        catch{
            this.setState({error: 'No Definition Found'})
        }
        console.log(this.props)
    }

Parent component:

class App extends Component {

  state = {
    redirect: {},
    word: '',
    error: '',
    info: [],
    partOfSpeech: [],
    versions: [],
    shortdef: "",
    pronunciation: "",
  }
  

  setRedirect = redirect =>
    this.setState({redirect})


  handleUpdate = (props) => 
    this.setState({word:this.props})


render() {
    return (
      <>
        <Route 
          render={ routeProps => <Redirector redirect={this.state.redirect} setRedirect={this.setRedirect} {...routeProps} />}
        />
        <header>
          <nav>
            <Link to='/'>My Dictionary</Link>
          </nav>

        <main>
        <Route
            render = { routeProps =>
              !routeProps.location.state?.alert ? '' :
              <div>
                { routeProps.location.state.alert }
              </div>
            }
          />
          <Switch>
            <Route exact path="/" render={ routeProps => <Home handleUpdate={this.handleUpdate} {...routeProps} />} />
            <Route exact path="/definition/:word" render={ routeProps => <GetWordContainer word={this.state.word} {...routeProps} />} />
          </Switch>
        </main>
      </>
    );
  }

export default App;

ANSWER

Answered 2020-Jul-17 at 06:47

If I can decipher your partial snippets, it seems handleUpdate in App is access the wrong "props" object, i.e. this.props of App instead of the passed props argument to the function.

Solution

Change the function parameter to something other than "props" to remove confusion, word is a great choice that allows you to also use object shorthand assignment.

handleUpdate = word => this.setState({ word });

Based on the object shape you pass to handleUpdate and your state object, I'm going to guess that you more likely want to spread in the object versus assigning it all to this.state.word

handleUpdate = values => this.setState({ ...values });
