RESTful POST JSON flash not working

I have a problem sending JSON via curl from cmd (Windows7) to Flask RESTful. Here is what I post:

curl.exe -i -H "Content-Type: application/json" \ -H "Accept: application/json" -X POST \ -d '{"Hello":"Karl"}' http://example.net:5000/

This leads to bad requests, also I don’t know how to debug this, usually I print information to the console, but it doesn’t work. How do you debug wsgi applications? It seems like a hopeless task ...

This is my simple test application, as shown on the net:

 from flask import Flask, request from flask.ext.restful import Resource, Api app = Flask(__name__) api = Api(app) class Test(Resource): def post(self): #printing request.data works json_data = request.get_json(force=True) # this issues Bad request # request.json also does not work return {} api.add_resource(Test, '/') if __name__ == '__main__': app.run(debug=True)

-d '{"Hello":"Karl"}' does not work from windows, surrounded by single quotes. Use double quotes and it will work for you.

 -d "{\"Hello\":\"Karl\"}"

I just want to point out that you need to run away regardless of the OS - and regardless of whether you have double quotes around the request data - I saw this post and did not think it was the answer to my question, because I had a double quotes request data and single quotes inside:

This will not work:

 -d "{'Hello': 'Karl'}"

This will:

 -d "{\"Hello\":\"Karl\"}"

Again, you need to avoid quotation marks, regardless of the OS (I'm on a Mac), and whether you have single or double quotes

And thanks to Sabuj Hassan for your reply!

To add to the previous two answers, you do not need to avoid quotes in all OSs, after that the syntax will work fine on Mac / Linux:

 -d '{"Hello":"Karl"}'
