flask post request python code example

Example 1: simple flask app

# Extremely simple flask application, will display 'Hello World!' on the screen when you run it
# Access it by running it, then going to whatever port its running on (It'll say which port it's running on).
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

if __name__ == '__main__':
    app.run()

Example 2: get arguments from url flask

from flask import request

@app.route(...)
def login():
    username = request.args.get('username')
    password = request.args.get('password')

Example 3: get requests method flask

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)
