Question

所以我尝试使用Flask框架进行练习项目的tweepy auth ..但是当我尝试使用Tweepy和Flask使用OAuth时，我得到302返回说明无法获取访问令牌..请帮助..下面的代码和错误消息..

from flask import Flask, redirect, url_for, session, request, render_template, flash
import tweepy
import flask

app = Flask(__name__)
app.config.from_object('config')
oauth = OAuth()
consumer_key = app.config["CONSUMER_ID"]
consumer_secret = app.config["CONSUMER_SECRET"]
access_token_key = app.config["ACCESS_KEY"]
access_token_secret = app.config["ACCESS_SECRET"]

callback_url = 'http://localhost:5000/verify'
session = dict()
db = dict()



@app.route('/')
def send_token():
    redirect_url = ""
    auth = tweepy.OAuthHandler(consumer_key, consumer_secret, callback_url)

    try: 
        #get the request tokens
        redirect_url= auth.get_authorization_url()
        session['request_token']= (auth.request_token.key,
            auth.request_token.secret)
    except tweepy.TweepError:
        print 'Error! Failed to get request token'

    #this is twitter's url for authentication
    return flask.redirect(redirect_url)


@app.route("/verify")
def get_verification():

    #get the verifier key from the request url
    verifier= request.args['oauth_verifier']

    auth = tweepy.OAuthHandler(CONSUMER_TOKEN, CONSUMER_SECRET)
    token = session['request_token']
    del session['request_token']

    auth.set_request_token(token[0], token[1])

    try:
            auth.get_access_token(verifier)
    except tweepy.TweepError:
            print 'Error! Failed to get access token.'

    #now you have access!
    api = tweepy.API(auth)

    #store in a db
    db['api']=api
    db['access_token_key']=auth.access_token.key
    db['access_token_secret']=auth.access_token.secret
    return flask.redirect(flask.url_for('index'))

@app.route("/index")
def index():
    #auth done, app logic can begin
    api = db['api']

    #example, print your latest status posts
    return flask.render_template('tweets.html', tweets=api.user_timeline())


if __name__ == '__main__':
    app.run()

Answer 1

原来问题是因为tweepy软件包没有更新到Pypi的最新版本..我从他们的github repo安装它并且它工作正常...

Answer 2

未从配置文件中正确读取consumer_key和consumer_secret。您可以通过在代码开头对这些键进行硬编码来测试它。其他一切似乎都很好，对我有用！

Answer 3

我注意到tweepy需要一些更新。看来OauthHandler无法从Python文件夹结构正确加载。我仍在学习导入结构的工作原理。

如果我转到安装了Tweepy库的安装路径，然后将auth.py文件复制到我的本地工作目录中，并重命名为auth_temp.py。然后，我可以毫无问题地访问其中的OAuthHandler类。
