你需要将GET改为POST。例子......你需要把GET改成POST。

if request.method == "POST":
    username = request.POST['username']
    password = request.POST['password']

    user = authenticate(request, username=username, password=password)
    if user is not None:
        login(request, user)
        # Redirect to a success page.
        ...
    else:
        # Return an 'invalid login' error message.
        ...
