How to allow POST method with Flask?

Question

I'm doing a web Flask app with "sign up" and "log in" functions. I'd like to use a POST method for the "sign up" function, like this:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return "Index"

@app.route("/signup/<username>,<password>" , methods = ['POST'])
def signup(username, password):

    return "Hello %s ! Your pw is %s" % (username,password)


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

But when I ran it, I received this error : "Method not allowed. The method is not allowed for the requested URL."

How can I do? Thanks in advance.

You could use something like this perhaps.

from flask import Flask, request, render_template, url_for, redirect

...

@app.route("/signup/<username>,<password>", methods = ['GET', 'POST'])
def signup(username, password):
    if request.method == 'POST':
        # Enter your function POST behavior here
        return redirect(url_for('mainmenu'))    # I'm just making this up
    else:
        return "Hello %s ! Your pw is %s" % (username,password)
        # Or you could try using render_template, which is really handy
        # return render_template('signupcomplete.html')

You'd have to flesh it out with the various things you need it to do, but that basic structure should be what you need. I've used it myself in some projects.
