Is it possible to make POST request in Flask?

For the record, here's general code to make a POST request from Python:

#make a POST requestimport requestsdictToSend = {'question':'what is the answer?'}res = requests.post('http://localhost:5000/tests/endpoint', json=dictToSend)print 'response from server:',res.textdictFromServer = res.json()

Notice that we are passing in a Python dict using the json= option. This conveniently tells the requests library to do two things:

1. serialize the dict to JSON
2. write the correct MIME type ('application/json') in the HTTP header

And here's a Flask application that will receive and respond to that POST request:

#handle a POST requestfrom flask import Flask, render_template, request, url_for, jsonifyapp = Flask(__name__)@app.route('/tests/endpoint', methods=['POST'])def my_test_endpoint():    input_json = request.get_json(force=True)     # force=True, above, is necessary if another developer     # forgot to set the MIME type to 'application/json'    print 'data from client:', input_json    dictToReturn = {'answer':42}    return jsonify(dictToReturn)if __name__ == '__main__':    app.run(debug=True)

Yes, to make a POST request you can use urllib, see the documentation.

I would however recommend to use the requests module instead.

EDIT:

I suggest you refactor your code to extract the common functionality:

@app.route("/test", methods=["POST"])def test():    return _test(request.form["test"])@app.route("/index")def index():    return _test("My Test Data")def _test(argument):    return "TEST: %s" % argument
