如何在GAE cron作业中执行OAuth操作？

这篇文章是How to do OAuth-requiring operations in a GAE Task Queue?的后续内容.正如bossylobster在这篇文章中所建议的,我确实尝试在我的脚本中硬编码user_id,但是cron任务总是失败：

>我可以看到它在日志中被触发……

2013-05-31 14:20:00.879 /update 302 5ms 0kb AppEngine-Google; (+http://code.google.com/appengine)
0.1.0.1 - - [31/May/2013:11:20:00 -0700] "GET /update HTTP/1.1" 302 385 - "AppEngine-Google; (+http://code.google.com/appengine)" "myapp.appspot.com" ms=6 cpu_ms=0 cpm_usd=0.000043 queue_name=__cron task_name=... app_engine_release=1.8.0 instance=...

> …但是,它总是失败(在AppEngine的Cron Jobs部分显示为红色“失败”),它应该运行的任务队列永远不会弹出任务队列部分.

我不明白的是,如果我手动打开/更新,我在下面有登录提示. cron如何绕过那个？我该如何调试正在进行的操作？

谢谢您的帮助.

对@dlebech进行编辑/跟进回答：在app.yaml中添加登录后,问题仍然存在：admin行到相关网址.在本地(通过以管理员身份登录并访问Securing URLs for Cron中提到的浏览器中处理程序的URL)一切顺利,但是一旦部署,我的应用程序永远不会超过OAuth2装饰器：

>使用一些调试打印语句……

import webapp2
...

YOUTUBE_RW_SCOPE = "https://www.googleapis.com/auth/youtube"
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"
print "Building youtube object"
print "Built youtube object"
youtube = build(YOUTUBE_API_SERVICE_NAME,YOUTUBE_API_VERSION)
print "Building decorator object"
decorator = OAuth2DecoratorFromClientSecrets(CLIENT_SECRETS,YOUTUBE_RW_SCOPE)
print "Built decorator object"
...

class FetchHandlerPage(webapp2.RequestHandler):
    print "Entering FetchHandlerPage"

    @decorator.oauth_required
    def get(self):
        print "Entering FetchHandlerPage:get"
        gae_user_id = USER_ID
        query_string = urlencode({'user_id': gae_user_id})
        taskqueue.add(url='/fetchworker?' + query_string,method='GET')

最佳答案

How is cron supposed to bypass that?

确保cron url配置了login：admin而不是login：required. Cron作业“自动通过登录提示”.有关更多信息,请参见the documentation.

How can I debug what’s going on?

由于cron作业是通过对特定URL的GET请求启动的,因此您应该能够通过向该URL发出GET请求来调试作业,并查看开发服务器发生的错误或查看日志中的内容. GET请求.
