QUESTION

SignalR never start on iOS using Xamarin Forms

Asked 2022-Mar-24 at 14:13

I'm trying to use SignalR in my Xamarin Forms project. It works perfectly when I'm using Android (device or simulator). But using the same code on iOS, it hangs at await hubConnection.StartAsync();

I'm using Visual Studio 2022. XAML hot reload is disabled. I've tried adding the System.Memory and System.Buffers IncludeAssets None fix.

Here's the code

public async Task StartObserving()
{
    Uri signalRUri = new Uri("a-valid-uri-string-here");
    string jwt = await SecureStorage.GetAsync(SecureStorageKeys.IdToken);

    HubConnection hubConnection = new HubConnectionBuilder()
        .WithUrl(
            signalRUri,
            options =>
            {
                options.AccessTokenProvider = () => Task.FromResult(jwt);
                options.WebSocketConfiguration = (clientWebSocketOptions) =>
                {
                    clientWebSocketOptions.RemoteCertificateValidationCallback = (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) =>
                    {
                        return true;
                    };
                };
                options.HttpMessageHandlerFactory = (httpMessageHandler) =>
                {
                    if (httpMessageHandler is HttpClientHandler clientHandler)
                    {
                        clientHandler.ServerCertificateCustomValidationCallback = (HttpRequestMessage httpRequestMessage, X509Certificate2 certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) =>
                        {
                            return true;
                        };
                    }

                    return httpMessageHandler;
                };
            })
        .ConfigureLogging(logging =>
        {
            logging.SetMinimumLevel(LogLevel.Trace);
            logging.AddConsole();
        })
        .Build();

    hubConnection.On<string>(
        "Send",
        OnMessageReceivedFromSignalR);

    await hubConnection.StartAsync();
}

Here's the SignalR log

Well I had only half of the solution implemented.

What fixed it for me was adding this to BOTH the common AND iOS projects. Not only the common project.

<PackageReference Include="System.Buffers">
  <Version>4.5.1</Version>
  <IncludeAssets>none</IncludeAssets>      
</PackageReference>
<PackageReference Include="System.Memory">

QUESTION

Filter button with Javascript & React

Asked 2022-Feb-24 at 15:18

Good day! I am hoping to get some help with a project I am working on. I created a filter functionality so that when a user click on a button, they can filter my projects based on what type of project it is.

I was able to get the "ALL" button to work but the other buttons are not working. The expected output is when I click on the button it filters out the other projects and keeps the one that matches the category. However the current output is when I click on the button, the projects disappear.

This is my code:

    import React, {useState} from "react";
import ReactDOM from "react-dom";
import styles from "./projects.module.scss";
import cards from "./allData";


function Projects() {
 
  const [state, setState] = useState(cards);

  const handleBtns = (e) => {
      let word = e.target.value;
      function isCardActive() {
        for(const card of cards) {
            if (cards.category === "FEATURED") {
                return true;
            } else if (cards.category === "WEB APP") {
                return true;
            } else if (cards.category === "MOBLE APP"){
                return true
            }
        } 
      };

      if(word === 'All') { 
          setState(cards)
      } else if(word === 'Featured') {
          const filtered = cards.filter(isCardActive);
          setState(filtered);

    }  else if(word === 'webApp') {
        const filtered = cards.filter(isCardActive);
        setState(filtered);

  } else if(word === 'mobileApp') {
    const filtered = cards.filter(isCardActive);
    setState(filtered);
  }
}


    return(
        <div className={styles.projects} id="projectHash">
           <section>
               <h3>PROJECTS</h3>

            <section>

           {state.map((cards) => (
                <div className={styles.projectcard} key={cards.id} >

                <h4>Project Name: {cards.title} </h4>
                <br/>
                <h4>{cards.image}</h4>

           ))}
           </section>

So there's a whole lot going on in this that makes it not work, but basically your isCardActive does nothing because it doesn't receive the current card item to compare against.

I've created a sandbox here with how it should work, using useState and useEffect to filter the results when the filter (currentCard) changes. I've removed the styling, but you can add that back pretty easy.

And the code is here:

const [cards, setCards] = useState(allCards);
const [currentCard, setCurrentCard] = useState("All");

const handleBtns = (e) => {
  let word = e.target.value;
  setCurrentCard(word);
};

useEffect(() => {
  if (currentCard === "All") {
    setCards(allCards);
  } else {
    const filtered = allCards.filter((card) => {
      return (
        card.category === currentCard || card.category.includes(currentCard)
      );
    });
    setCards(filtered);
  }
}, [currentCard]);

return (
  <div className="App">
    <div id="projectHash">
      <section>
        <h3>PROJECTS</h3>
      </section>

      <section>
        <button onClick={handleBtns} type="button" value="All">
          VIEW ALL
        </button>
        <button onClick={handleBtns} type="button" value="FEATURED">

        </button>
        <button onClick={handleBtns} type="button" value="WEB APP">
          WEB APP
        </button>
        <button onClick={handleBtns} type="button" value="MOBILE APP">
          MOBILE APP
        </button>
      </section>

      <h3>Current: {currentCard}</h3>

      <section>
        {cards.map((card) => (
          <div key={card.id}>
            <h4>Project Name: {card.title} </h4>
          </div>
        ))}

Activity not showing using NavController

Answered 2022-Jan-21 at 04:25

As per the documentation:

Caution: When manually calling setGraph(), note the following:

Don't use the app:navGraph element when adding the NavHostFragment in XML.

Don't call NavHostFragment.create(@NavigationRes int).

Don't use any other APIs that rely solely on the R.navigation ID to inflate and set your graph.

So just remove your app:navGraph attribute from your XML file to only set your graph via setGraph after your addition of your custom Navigator.

QUESTION

Microservice : How can you deploy your Microservices project using an API gateway on windows server

Asked 2021-Dec-27 at 15:16

I have created two projects one the API Gateway that uses this JSON file:

{
  "Routes": [
    {
      "DownstreamPathTemplate": "/api/post",
      "DownstreamScheme": "https",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 44309
        }
      ],
      "UpstreamPathTemplate": "/gateway/post",
      "UpstreamHttpMethod": [
        "POST",
        "PUT",
        "GET"
      ]
    }
  ]
}

And on the Microservice side the other project i have created a PostController that inherits Controllerbase, basically an ApiController:

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using PostService.Repository;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

        namespace PostService.Controllers
        {
            [Route("api/[controller]")]
            [ApiController]
            public class PostController : ControllerBase
            {
                private readonly IPostRepository _postRepository;

                public PostController(IPostRepository postRepository)
                {
                    _postRepository = postRepository;
                }

                [HttpGet]
                public IActionResult Get()
                {
                    var posts = _postRepository.GetPosts();
                    return new OkObjectResult(posts);
                }

            }
        }

When I run the project Two browsers open, the first which is the ApiGateway and the other browser is where the microservice runs on localhost on port 44309. I run this in the address bar for the api gateway:

https://localhost:44342/gateway/post

The great thing is that the Get Method in my PostController get called and returns the data correctly.

But if I wanted to run or deploy these projects on windows server, how would this work on a windows server. What would I need to change in my ocelot.json file or does this remain the same or do O need to change these values to the remote IP and port:

    "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 44309
        }
      ],

So could someone point me in the right direction on how to deploy this on a windows server so that maybe a web or mobileapp can access the APIGateway?

ANSWER

Answered 2021-Dec-27 at 08:20

To deploy it on a Windows Server you need to create two web sites on IIS, one for the API Gateway and one for the microservice. The API gateway site should listen on https port 443 and any IP address. The microservice can listen in any port of your choice, but there is no need to configure it for https because the communication between the gateway and the microservice is local to the server. The microservice should listen only on 127.0.0.1 and [::1] IP addresses because the microservice should only be accessed though the API gateway. So your ocelot.json can be:

{
  "Routes": [
    {
      "DownstreamPathTemplate": "/api/post",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 44309
        }
      ],
      "UpstreamPathTemplate": "/gateway/post",
      "UpstreamHttpMethod": [
        "POST",
        "PUT",
        "GET"
      ]
    }
  ]
}

Don't forget to configure the microservice site bindings for http on port 44309 or the port of your choice

In Android it works well, but in iOS I got an error:

If I remove theses items in the constructor of the ContentPage it does not crash, I tried to use only Text, in Android I am using icon and works...

    public HomePage()
    {
        InitializeComponent();

        if (DeviceInfo.Platform == DevicePlatform.iOS)  
        {
            this.ToolbarItems.Clear();
        }            
    }

Is this a bug? In github I saw few issue about toolbar.

Updated with the entire code base. There is multiple map statements. If that is the issue how do you map multiple arrays inside React? Does that require using some sort of data store? It is returning each one of the images 4 times, rather than each images per card.

ANSWER

Answered 2021-Aug-08 at 06:23

Array.map returns array. So catImage is an array that contains components.
You can use each CardMedia component by indicating index number.

catImage[index]

catImage[0] is the first card. So you can update your code like below:

const cards = (           // <==== line 74
  <Fragment>
    {categories.map((c, index) => (
      <Card style={{ width: "15.625rem", wordWrap: "break-word" }}>
        <div>{catImage[index]}</div>

I hope my answer will be solve your problem.
Thanks.

QUESTION

Ktor httpclient auth feature not working on IOS

Asked 2021-Aug-05 at 08:53

I am developing a KMM project and the authentication works well on the Android app. However when I added the Auth feature in the httpclient (located in the shared.commonMain) the ios app failled at runtime with the following message

Function doesn't have or inherit @Throws annotation and thus exception isn't propagated from Kotlin to Objective-C/Swift as NSError. It is considered unexpected and unhandled instead. Program will be terminated.

This is how I create the httpclient

private val httpclient = HttpClient() {
    engine {
        pipelining = true
        threadsCount = 4
    }
    install(Logging) {
        level = LogLevel.HEADERS
        logger = object : Logger {
            override fun log(message: String) {
                Napier.v(tag = "HTTP Client", message = message)
            }
        }
    }
    install(JsonFeature) {
        val json =  Json { ignoreUnknownKeys = true }
        serializer = KotlinxSerializer(json)
    }
    install(Auth) {
        basic {
            credentials {
                BasicAuthCredentials(username = emailUser, password = passwordUser)
            }
        }
    }
}.also {
    initLogger()
}

Here is the complete code of the Greeting class:

class Greeting {
private var emailUser: String = ""
private var passwordUser: String = ""

private val httpclient = HttpClient() {
    engine {
        pipelining = true
        threadsCount = 4
    }
    install(Logging) {
        level = LogLevel.HEADERS
        logger = object : Logger {
            override fun log(message: String) {
                Napier.v(tag = "HTTP Client", message = message)
            }
        }
    }
    install(JsonFeature) {
        val json =  Json { ignoreUnknownKeys = true }
        serializer = KotlinxSerializer(json)
    }
    install(Auth) {
        basic {
            credentials {
                BasicAuthCredentials(username = emailUser, password = passwordUser)
            }
        }
    }
}.also {
    initLogger()
}

@Throws(Exception::class)
suspend fun getVaccines(): List<Vaccine> {
    return httpclient.get(endpointBase + Vaccine.path)
}

@Throws(Exception::class)
suspend fun loginUser(email: String, password: String): String? {
    emailUser = email
    passwordUser = password
    return httpclient.get(endpointBase + User.path + "/userPage")

Exact solution:

moved emailUser and passwordUser in commonMain.Platform

expect var emailUser: String  
expect var passwordUser: String

androidMain.Platform

actual var emailUser = "" 
actual var passwordUser = ""

iosMain.Platform

actual var emailUser: String = AtomicReference("").value
actual var passwordUser: String = AtomicReference("").value

You need to check out how kotlin-native concurrent-mutability works

In short, you can't use any var in your shared code, that may be accessed from different threads. You had to wrap those values with Atomic containers. Replace both emailUser and passwordUser with something like this:

private val emailUser = Atomic("")
private val passwordUser = Atomic("")

Also you can use delegated-properties so you don't need to write .value each time

There's no Atomic declarations for common code, so you have to do you by yourself. In actual for iOS you can use native atomics and for android just make a simple wrapped.

Good news is that this won't stay for long, as JetBrains is planning to change concurrency model soon before KMP release. But for now we had to deal with it.
