Error when redirecting with Twitter oauth












1















I'm new to Flask and I'm trying to do do oauth with Twitter using Twython. Following is my code (development version):



OAUTH_TOKEN = ''
OAUTH_TOKEN_SECRET = ''
callback_url = 'http://127.0.0.1:5000/verify'
@app.route('/')
def hello(name=None):
return render_template('index.html', name=name)

@app.route('/auth', methods=['POST'])
@cross_origin()
def obtain_auth_url():
global OAUTH_TOKEN, OAUTH_TOKEN_SECRET
social_network = request.get_json()['social_network']
if social_network == 'facebook':
return ''
elif social_network == 'twitter':
twitter = Twython(APP_KEY, APP_SECRET)
auth = twitter.get_authentication_tokens(callback_url)
OAUTH_TOKEN = auth['oauth_token']
OAUTH_TOKEN_SECRET = auth['oauth_token_secret']
redirect_url= auth['auth_url']
response = redirect(redirect_url)
response.headers = {'Access-Control-Allow-Origin': 'https://api.twitter.com/'}
print('redirect_url: ',redirect_url)
return response

@app.route("/verify")
def get_verification():
global OAUTH_TOKEN
global OAUTH_TOKEN_SECRET
twitter = Twython(APP_KEY, APP_SECRET,OAUTH_TOKEN, OAUTH_TOKEN_SECRET)
final_step = twitter.get_authorized_tokens(request.args['oauth_verifier'])
OAUTH_TOKEN2 = final_step['oauth_token']
OAUTH_TOKEN_SECRET2 = final_step['oauth_token_secret']
return 'OK!</br> OAUTH TOKEN:' + OAUTH_TOKEN2 +'</br> OAUTH TOKEN SECRET: '+ OAUTH_TOKEN_SECRET2


Note that in the code, I add the header Access-Control-Allow-Origin to enable the redirect to twitter api domain. If I don't include the header, it throws a cross origin block error.
However, on the browser (Firefox), is said:




XML Parsing Error: syntax error Location: http://127.0.0.1:5000/auth
Line Number 1, Column 55:




Clearly, the endpoint /auth has been reached because I can see the redirect url via log, but I don't understand why I have the error.
Please help.
