how to access form data using flask?
My login endpoint looks like
@app.route('/login/', methods=['GET', 'POST'])
def login():
if request.method == 'POST':
print request.form # debug line, see data printed below
user = User.get(request.form['uuid'])
if user and hash_password(request.form['password']) == user._password:
login_user(user, remember=True) # change remember as preference
return redirect('/home/')
else:
return 'GET on login not supported'
When I test this using curl, the GET call looks like
⮀ ~PYTHONPATH ⮀ ⭠ 43± ⮀ curl http://127.0.0.1:5000/login/
GET on login not supported
but on POST, I am not able to access the form data and get HTTP 400
⮀ ~PYTHONPATH ⮀ ⭠ 43± ⮀ curl -d "{'uuid': 'admin', 'password': 'admin'}" http://127.0.0.1:5000/login/
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>The browser (or proxy) sent a request that this server could not understand.</p>
On the server though, my debug information prints the following
ImmutableMultiDict([("{'uuid': 'admin', 'password': 'admin'}", u'')])
where I do print request.form. I am not able to understand where I am doing wrong
Answer
You are not using curl correctly. Try like this:
curl -d 'uuid=admin&password=admin'
The 400 Bad Request error is the usual behavior when you try to get nonexistent keys from request.form.
Alternatively, use request.json instead of request.form and call curl like this:
curl -d '{"uuid":"admin","password":"admin"}' -H "Content-Type: application/json"
