Answer:

Unfortunately doing this directly by attempting to web scrape the search results using UrlFetchApp will not work. You can use third party tools to get the number of search results, however.

More Information:

I tested this out using an exponential backoff method which sometimes is able to get past 429 errors when a fetch request is invoked by UrlFetchApp.

When using UrlFetchApp to either web scrape or to connect to an API, it can happen that the server denies the request on the grounds of too many requests - or HTTP Error 429.

Google Apps Script runs in the cloud, from a set of IP addresses in a pool that Google own. You can actually see all the IP ranges here. Most websites (especially large companies such as Google) have architecture in place to prevent the use of bots scraping their websites and slowing down traffic.

Sometimes it's possible to get past this error, using a mixture of exponential backoff and random time intervals as shown for the Binance API (Full Disclosure: this GitHub repository was written by me.)

I assume that either Google directly blocks the Apps Script IP pool, or there are simply too many people trying the same thing - because with the same techniques I was unable to get any response that didn't involve entering a captcha as we discussed in the comments above and can be seen in the log of the page string.

What can be done:

There are many third party APIs that you can use to do this, and I suggest searching for one that meets your needs.

I tested out one called Authoritas which returns search engine indexing for different keywords. The API is asynchornous, so can take up to a minute to get a response, so a Web App solution needs to be made.

The flow I used is as follows:

Obtain API key from Authoritas (free)

QUESTION

Java Socket Read Input Twice

Asked 2021-Jun-14 at 19:05

I have a situation with a Java Socket Input reader. I am trying to develop an URCAP for Universal Robots and for this I need to use JAVA.

The situation is as follow: I connect to the Dashboard server through a socket on IP 127.0.0.1, and port 29999. After that the server send me a message "Connected: Universal Robots Dashboard Server". The next step I send the command "play". Here starts the problem. If I leave it like this everything works. If I want to read the reply from the server which is "Starting program" then everything is blocked.

I have tried the following:

-read straight from the input stream-no solution

-read from an buffered reader- no solution

-read into an byte array with an while loop-no solution

I have tried all of the solution presented here and again no solution for my case. I have tried even copying some code from the Socket Test application and again no solution. This is strange because as mentioned the Socket Test app is working with no issues.

Below is the link from the URCAP documentation:

https://www.universal-robots.com/articles/ur/dashboard-server-cb-series-port-29999/

I do not see any reason to post all the trials code because I have tried everything. Below is the last variant of code maybe someone has an idea where I try to read from 2 different buffered readers. The numbers 1,2,3 are there just so I can see in the terminal where the code blocks.

In conclusion the question is: How I can read from a JAVA socket 2 times? Thank you in advance!

ANSWER

Answered 2021-Jun-11 at 12:14

The problem seems to be that you are opening several input streams to the same socket for reading commands.

You should open one InputStream for reading, one OutputStream for writing, and keep them both open till the end of the connection to your robot.

Then you can wrap those streams into helper classes for your text-line based protocol like Scanner and PrintWriter.

You will need JavaScript for all your functional requirements. You can use the onclick handler to capture the click event and call a function that changes the active slide.

Something like this, using a recursive macro, might be closer to what you want, since your structure has both lists (children) and dicts (the objects within).

How to properly configure spring-security with vaadin14 to handle 2 entry points - keyclaok and DB

Asked 2021-Jun-06 at 08:12

I have a vaadin14 application that I want to enable different types of authentication mechanisms on different url paths. One is a test url, where authentication should use DB, and the other is the production url that uses keycloak.

I was able to get each authentication mechanism to work separately, but once I try to put both, I get unexpected results.

In both cases, I get login page, but the authentication doesn't work correctly. Here's my security configuration, what am I doing wrong?

...

ANSWER

Answered 2021-Jun-06 at 08:12

Navigating within a Vaadin UI will change the URL in your browser, but it will not necessarily create a browser request to that exact URL, effectively bypassing the access control defined by Spring security for that URL. As such, Vaadin is really not suited for the request URL-based security approach that Spring provides. For this issue alone you could take a look at my add-on Spring Boot Security for Vaadin which I specifically created to close the gap between Spring security and Vaadin.

But while creating two distinct Spring security contexts based on the URL is fairly easy, this - for the same reason - will not work well or at all with Vaadin. And that's something even my add-on couldn't help with.

Update: As combining both security contexts is an option for you, I can offer the following solution (using my add-on): Starting from the Keycloak example, you would have to do the following:

Change WebSecurityConfig to also add your DB-based AuthenticationProvider. Adding your UserDetailsService should still be enough. Make sure to give every user a suitable role.
You have to remove this line from application.properties: codecamp.vaadin.security.standard-auth.enabled = false This will re-enable the standard login without Keycloak via a Vaadin view.
Adapt the KeycloakRouteAccessDeniedHandler to ignore all test views that shouldn't be protected by Keycloak.

I already prepared all this in Gitlab repo and removed everything not important for the main point of this solution. See the individual commits and their diffs to also help focus in on the important bits.

.htaccess allow social media crawlers to work (Facebook and Twitter) | Angular 11 SPA

Asked 2021-May-31 at 15:19

I've created a SPA - Single Page Application with Angular 11 which I'm hosting on a shared hosting server.

The issue I have with it is that I cannot share any of the pages I have (except the first route - /) on social media (Facebook and Twitter) because the meta tags aren't updating (I have a Service which is handling the meta tags for each page) based on the requested page (I know this is because Facebook and Twitter aren't crawling JavaScript).

In order to fix this issue I tried Angular Universal (SSR - Server Side Rendering) and Scully (creates static pages). Both (Angular Universal and Scully) are fixing my issue but I would prefer using the default Angular SPA build.
