url_for() Function in Flask
Another method you can use when performing redirects in Flask is the url_for() function URL building. This function accepts the name of the function as the first argument, and the function named user(name) accepts the value through the input URL. It checks whether the received argument matches the ‘admin’ argument or not. If it matches, then the function hello_admin() is called else the hello_guest() is called.
Python3
from flask import Flask, redirect, url_forapp = Flask(__name__)# decorator for route(argument) function@app.route('/admin')# binding to hello_admin calldef hello_admin(): return 'Hello Admin'@app.route('/guest/<guest>')# binding to hello_guest calldef hello_guest(guest): return 'Hello %s as Guest' % guest@app.route('/user/<name>')def hello_user(name): # dynamic binding of URL to function if name == 'admin': return redirect(url_for('hello_admin')) else: return redirect(url_for('hello_guest' , guest=name))if __name__ == '__main__': app.run(debug=True) |
Output:
hello_guest function
hello_user function
