Menu
I'm practicing writing a rest api in flask, and I'd like to save a username as a session variable, and have it accessible in each route. I'd like to just interact with this program through the command line via curl.
from flask import Flask, Response, session, request, url_for, redirect
import json
app = Flask(__name__)
app.secret_key = 'blabla'
@app.route('/')
def index():
print 'Inside index route'
if 'username' in session:
username = session['username']
print 'Logged in as {}'.format(username)
return Response(response='Logged In\n', status=200, mimetype='text')
else:
print 'Not logged in'
return Response(response='Not Logged In\n', status=200, mimetype='text')
@app.route('/login', methods=['GET', 'POST'])
def login():
print 'Inside login route'
if request.method == 'POST':
session['username'] = json.loads(request.data)['username']
print session['username']
return redirect(url_for('index'))
@app.route('/logout')
def logout():
session.pop('username', None)
return redirect(url_for('index'))
if __name__ == '__main__':
app.run(debug=True)
When I curl the site with:
curl -X POST -H 'Content-Type: application/json' http://127.0.0.1:5000/login -d '{"username": "mdito"}'
I get the output:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>Redirecting...</title>
<h1>Redirecting...</h1>
<p>You should be redirected automatically to target URL: <a href="/">/</a>. If not click the link.
On the server side I am seeing:
Inside login route
mdito
If I'm redirecting to the index url, why does 'Inside index route' not appear on the server side? And why does 'Logged In' not get returned to the user?

Because flask does 302 redirect from /url to /url/. To avoid redirects add / at the end:
@app.route('/login/', methods=['GET', 'POST'])
Docs (see Unique URLs / Redirection Behavior part). That's it.
