If you use the browser inspector (dev tools - network tab) you can see that, every time you hit "Search" it makes a get request to this kind of url: https://slider.kz/vk_auth.php?q=unravel

The response is a JSON with the results.

So, if you want to use requests you should get this url and then extract the information from the response JSON.

This is one crude way of doing things: You can define the output model and assign initial values (in this case 0's) and iterate through your array and make necessary manipulations.

If you have many values for persediaanName, then you can consider maintaining an array of those values and then do the crude way.

Your shown dataset is too small to calculate (meaningful) variations. But you could use:

Since I haven't noticed you're already using Flask-CORS I'm updating this answer with some further investigations.

I've fired up a testing environment and managed to make this cross-origin request work properly without changing your code. During this process, I came up with the following possible reasons for your issue:

1. Be sure to request an existing tunnel endpoint. Fetching closed NGROK tunnel endpoints result in CORS error, it does not raise a 404. To be sure I'm requesting the correct tunnel I wrote an index view route that just returns success. I also used this endpoint to ensure the CORS was properly set for all HTTP methods (GET, POST...);
2. Be sure to import logging, Flask can lazy evaluate apps and raise exceptions only in request time. Check out your console for tracebacks;
3. In Flask, if an exception occurs during a request, the request handling flow is aborted and Flask-CORS will never be called to add it's headers in the response object, and your browser will always complain about 'Access-Control-Allow-Origin'. That's why you should always check your browser's 'Response Tab', it may contain a traceback or some other useful information;
4. Check for some info in NGROK introspect accessing http://localhost:4040/, it may help you track many issues;
5. I faced some issues running flask-ngrok provided through pip. I've downloaded its source code from GitHub and imported it into my demo app. Frankly, I would ditch this extension and just run $ ngrok http 5000 in another console;
6. Be sure to set FLASK_DEBUG=true or it may hide some info/tracebacks from you.

Check this Gist for the source code I've used and some evidence: https://gist.github.com/magnunleno/8dad91f133a22322250d6cb609792597

If you find any new info or traceback, please let me know so we can work out a solution.

That happens when you run your server under a specific domain (in your case e20e2287e2cb.ngrok.io) but your web client runs in a different domain (suppose www.abcabc.com) and they try to communicate. You should really take a look at this.

This behavior can be configured by managing your app headers Access-Control-* and, luckily, there is a nice extension that does that for you called Flask-CORS.

You don't need a loop, a temp table or even PL/pgSQL for this.

This can be achieved with a single query:

Likely related to tunesTeasers.map. A react key needs to be on the outer-most element mapped, the Fragment in this case. The teaser link appears to be unique within the set, but if it isn't, you may need to provide a unique id property to the elements to use as a react key.

You can try post the url that is being used to get the data. The return will be in a JSON format

I used the following url

One of the most basic approaches when you need a count of the number of times any element within a collection occurs for a given set is to use a Frequency Array. Very simply, a Frequency Array contains the number of elements that can occur for a collection. (e.g. with what frequency does the thing mapped to each index occur?)

For example, if you want to know the number of times any one alpha-character occurs within a line of text (ignoring case), your collection has 26-elements (the letters in the alphabet). So you would simply declare an array of 26-elements (usually int or size_t), initialized all zero, and then loop over the characters in your line of text, and for each alpha-character, you increment the corresponding element of the array.

For example, with the array int chars[26] = {0}; and for the line containing "Dog", you would simply increment:

I tried to Solve my posted Question and met Photon Support. They said to me below.

Those errors indicate an incompatibility between the stdlib version that your app links against and the one that the Photon libs link against.

The SDK provides libs that have been built against the gcc version of the stdlib (libstdc++) and libs that have been built against the clang version of the stdlib (libc++). The former ones are used on default and the lattter ones have an additional 'libc++' postfix in their filenames.

It looks like your app links against the clang version of the stdlib and against those builds of Photon libs that link against the gcc version of the stdlib.

However your app and all 3rd party libs that your apps link to must agreed on using the same version of the stdlib as those 2 incompatible versions can't be mixed with each other.

Please see https://forum.photonengine.com/discussion/comment/42718/#Comment_42718 for instructions on how to link against the libc++ variants of the Photon libs.

Doing so should fix your errors.

Looks like works for me... )
