import flask
app = flask.Flask('your_flask_env')

@app.route('/register', methods=['GET', 'POST'])
def register():
    if flask.request.method == 'POST':
        username = flask.request.values.get('user') # Your form's
        password = flask.request.values.get('pass') # input names
        your_register_routine(username, password)
    else:
        # You probably don't have args at this route with GET
        # method, but if you do, you can access them like so:
        yourarg = flask.request.args.get('argname')
        your_register_template_rendering(yourarg)

Flask post vs get

@app.route("/login", methods=["POST", "GET"])
def login():
    if request.method == "POST":
        user = request.form["name"]
        return redirect(url_for("success", name=user))
    else:
        user = request.args.get("name")
        return redirect(url_for("success", name=user))

Flask sending post request

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