flask session doesn't persist when invoke the call from c# mvc web application
I wrote a web service in python flask. In my code I have flask session object and it looks good.
Here is a short example how my python code look like-
@app.route('/api/simpleTry', methods=['GET']) def api_simple(): user_id = request.args['id'] sentence = request.args['sentence'] if 'user_id' not in session.keys(): session['user_id'] = user_id return jsonify("hello") app.run() when I invoke the service through ‘crome’ explorer it works good, the session persist and when I 2 open 2 clients (1- crome, 2-incognito) I can see that each one of them has a separate session.
in addition, I have a C# mvc web application that act as my client and over there I call the python flask service I wrote.
address = "http://localhost:5000/api/simpleTry?id=" + userId + "&sentence=" + sentence; using (var w = new WebClient()) { json_data = w.DownloadString(address); ... } The code works well. but, as opposed to ‘crome’, when sending the request from c#, the session in python does not persist and create a new session for each request.
I guess I should send something from C# to the service in order to use the existing session, but I don’t what and how.
Flask sessions uses cookies to communicate session information between the client & server. When you used a browser, the browser is the client & automatically sends the cookies back to the server. When you use a C# client, I’m not sure if it does that for you automatically. You may have to read the session cookie from the header & send it along with subsequent requests.
From the Flask documentation: This is implemented on top of cookies for you and signs the cookies cryptographically
