Question

There is a need to make POST request from server side in Flask.

Let’s imagine that we have:

@app.route("/test", methods=["POST"])
def test():
    test = request.form["test"]
    return "TEST: %s" % test

@app.route("/index")
def index():
    # Is there something_like_this method in Flask to perform the POST request?
    return something_like_this("/test", { "test" : "My Test Data" })

I haven’t found anything specific in Flask documentation. Some say urllib2.urlopen is the issue but I failed to combine Flask and urlopen. Is it really possible?

Answer 1

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
