Flask POST request is causing server to crash

First what you want to do is enable debug mode so Flask will actually tell you what the error is. (And you get the added benefit of flask reloading every time you modify your code!)

if __name__ == '__main__':    app.debug = True    app.run()

Then we find out our error:

TypeError: 'dict' object is not callable

You're returning request.json, which is a dictionary. You need to convert it into a string first. It's pretty easy to do:

def api_response():    from flask import jsonify    if request.method == 'POST':        return jsonify(**request.json)

There you are! :)

The server is overloaded because the default port(5000) or port explicitly mentioned by a user(eg:app.run(port=7000)) may be using some other processes in the background, so we need to kill the processes which are being used by that port.

You can see the process id's(PIDS) which are using that port by using the following command:netstat -o -a in command prompt*Look into the respective PID for the port

Then kill all the Processes(PIDS) for the port you want to use using the following command:Taskkill /PID 30832 /FHere I used the PID 30832 for port 127.0.0.1:7000 which is giving the overloaded error.After that problem is solved.

1.First of all you set :

if __name__ == '__main__':app.run(debug=TRUE)

2.The server(defaut) is busy in process ,first you terminate that process on that server:

You can see the process id's(PIDS) which are using that port by using the following command: netstat -o -a in command prompt.Enter here to see sampleLook into the corresponding PID for the port.

Then kill all the Processes(PIDS) for the port you want to use using the following command: Taskkill /PID 10324 /F Here I used the PID 10324 for port 127.0.0.1:5000 which is giving the overloaded error. After that problem is solved.
