Question

我正在尝试使用Google Calendar API授权Oauth2。我猜我的请求有问题，因为我收到redirect_uri mismatch错误。

我正在使用重定向uri urn:ietf:wg:oauth:2.0:oob，这是我Google Developer console项目中的原生应用程序。

登录页面将用户重定向到Googles授权页面，而/ oauth2callback将使用生成的Google代码从提交的表单中获取信息。代码是

@app.route('/login')
def login():
    flow = OAuth2WebServerFlow(client_id=CLIENT_ID,
                               client_secret=CLIENT_SECRET,
                               scope='https://www.googleapis.com/auth/calendar',
                               redirect_uri='urn:ietf:wg:oauth:2.0:oob',
                               approval_prompt='force',
                               access_type='offline')

    auth_uri = flow.step1_get_authorize_url()

    return redirect(auth_uri)


@app.route('/oauth2callback', methods=['POST', 'GET'])
def oauth2callback():
    code = request.form['code']
    if code:
        # exchange the authorization code for user credentials
        flow = OAuth2WebServerFlow(CLIENT_ID,
                                   CLIENT_SECRET,
                                   scope="https://www.googleapis.com/auth/calendar",
                                   redirect_uri='urn:ietf:wg:oauth:2.0:oob')
        flow.redirect_uri = request.base_url
        try:
            credentials = flow.step2_exchange(code)
            storage = Storage('credentials.dat')
            storage.put(credentials)

        except Exception as e:
            logging.warning("Unable to get an access token because "+e.message)

    return redirect('/')

为什么我得到＆＃34; redirect_uri_missmatch＆＃34;？
