Question

在完成本教程https://developer.uber.com/docs/riders/ride-requests/tutorials/api/python之后，我在尝试获取用户个人资料或活动等数据时遇到错误。

这是我的示例（Flask）代码：

import os
from datetime import datetime
from flask import Flask, request, flash, url_for, redirect, \
     render_template, abort, send_from_directory, redirect

from uber_rides.auth import AuthorizationCodeGrant
from uber_rides.session import Session
from uber_rides.client import UberRidesClient

app = Flask(__name__)
app.config.from_pyfile('flaskapp.cfg')

# Configure Uber Oauth2.0
auth_flow = AuthorizationCodeGrant(
    '<client_id>',
    ['profile', 'history'],
    '<client_secret>',
    'http://localhost:8080/callback'
    )

@app.route('/')
def index():
    auth_url = auth_flow.get_authorization_url()
    return redirect(auth_url, code=302)

@app.route('/callback')
def callback():
    session = auth_flow.get_session(request.url)
    client = UberRidesClient(session)
    credentials = session.oauth2credential

    # Fetch users profile
    response = client.get_user_profile()
    profile = response.json

    first_name = profile.get('first_name')
    last_name = profile.get('last_name')
    email = profile.get('email')

    # Fetch user activity
    response = client.get_user_activity()
    history = response.json

    return first_name, 200

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

跟踪错误：

这可能是优步服务的问题吗？

更新3： 我已经挖掘了rides_python_sdk并添加了额外的标题，如文档https://developer.uber.com/docs/riders/ride-requests/tutorials/api/curl#get-a-list-of-products-available

中所示

我还将Accept-Encoding参数更正为sdk ['gzip, deflate']

中的内容

仍然收到500错误

Answer 1

感谢您在调查此问题时的耐心等待。这是我们的v1 oauth端点中的一个潜在错误，它影响了新创建的应用程序。我发布了一个新版本的sdk来解决这个问题。请使用v0.4.0，您不应该有任何问题。感谢您提供详细的反馈！

Answer 2

我不得不使用另一个oauth lib（flask_oauthlib）。

import os, requests, logging
import httplib as http_client
from datetime import datetime
from flask import Flask, request, flash, url_for, redirect

from flask_oauthlib.client import OAuth
from flask import session, redirect

app = Flask(__name__)
app.config.from_pyfile('flaskapp.cfg')

http_client.HTTPConnection.debuglevel = 1
logging.basicConfig(level=logging.DEBUG)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.DEBUG)
requests_log.propagate = True

oauth = OAuth()
uber_app = oauth.remote_app(
        'uber',
        request_token_url=None,
        access_token_url='https://login.uber.com/oauth/v2/token',
        authorize_url='https://login.uber.com/oauth/v2/authorize',
        consumer_key='<client_id>',
        consumer_secret='<client_secret>'
    )

@app.route('/')
def index():
    #Make call to Uber service to retrieve products
    headers = {'Authorization' : 'Bearer '+session['uber_token'][0]}
    url = "https://api.uber.com/v1.2/"
    response_profile = requests.get(url+'me', headers=headers)
    response_history = requests.get(url+'history', headers=headers)

    return "<h3>Profile</h3><p>"+response_profile.content+"<h3>History</h3>"+response_history.content, 200

@uber_app.tokengetter
def get_uber_token(token=None):
    return session.get('uber_token')

@app.route('/login')
def login():
    return uber_app.authorize(callback=url_for('oauth_authorized', _external=True,
        next=request.args.get('next') or request.referrer or None))

@app.route('/oauth-authorized')
def oauth_authorized():
    next_url = request.args.get('next') or url_for('index')
    resp = uber_app.authorized_response()
    if resp is None:
        flash(u'You denied the request to sign in.')
        return redirect(next_url)

    session['uber_token'] = (
        resp['access_token'],
        resp['refresh_token']
    )

    flash('You were signed in')
    return redirect(next_url)

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

首先创建一个oauth实例并将params分配给remote_app方法。

注意： oauth2.0没有request_token_url，因此将其设置为None。

get_uber_token方法创建一个全局会话来存储您的令牌，可以从代码中的任何其他位置访问。
/login将用户重定向到优步登录页面。网址的一部分是重定向uri，优步将使用它来回调您的服务。

注意：请务必在_external=True方法中添加url_for param，以便生成uber服务为回调所需的绝对网址。

＆＃39; oauth_authorized＆＃39;方法和端点在授权阶段之后处理来自Uber服务的重定向。请记住获取并存储您以后需要的两个重要令牌; access_token和refresh_token
在授权成功后最终重定向到的index方法中，我已经拨打了一些电话来获取个人资料和车手历史记录以进行演示。注意发送的标题。

注意：请注意，承载令牌在大约10分钟后过期，并且您需要刷新令牌后才能请求另一个承载令牌。此处的日志记录只会将所有内容设置为DEBUG级别，以便您可以查看正在发送的内容。

使用Uber Rides Python SDK检索数据失败，出现500错误
