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

Question

遵循本教程 https://developer.uber.com/docs/riders/ride-requests/tutorials/api/python 后，我在尝试获取用户个人资料或 activity.

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)

这会不会是 Uber 服务的问题？

更新 3： 我已经深入研究 rides_python_sdk 并添加了额外的 headers，如文档 https://developer.uber.com/docs/riders/ride-requests/tutorials/api/curl#get-a-list-of-products-available

所示

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

中的内容

仍然出现 500 错误

Answer 1

感谢您在我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。我已经发布了一个新版本的 sdk 来解决这个问题。请使用 v0.4.0，你应该不会有任何问题。感谢您的详细反馈！

Answer 2

我不得不使用另一个 oauth 库（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实例并将参数分配给remote_app方法。

注： oauth2.0 没有request_token_url，所以设置为None.

get_uber_token 方法创建一个全局 session 来存储您的令牌，可以从代码中的其他任何地方访问它。
/login 将用户重定向到 Uber 登录页面。作为 url 的一部分，优步将使用重定向 uri 回调您的服务。

注意：确保在url_for方法中添加_external=True参数，以便生成需要的绝对url用于回调的优步服务。

'oauth_authorized' 方法和端点在授权阶段后处理来自 Uber 服务的重定向。请记住获取并存储您稍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，我进行了几次调用以获取个人资料和骑手历史记录以进行演示。留意发送的headers

注意： 请注意，Bearer 令牌将在大约 10 分钟后过期，之后您将需要刷新令牌来请求另一个 Bearer 令牌。此处的日志记录只是将所有内容设置为 DEBUG 级别，因此您可以查看在线发送的内容。
