Question

运行cron作业时遇到问题。 Cron作业总是在谷歌开发者控制台上显示失败，似乎没有办法找出原因。如果我使用网站appspot.com/crons/ftpcronjon它执行得很好。

这是我的代码：

import httplib2
import logging
import webapp2
from apiclient import discovery
from google.appengine.api import memcache
from oauth2client.appengine import AppAssertionCredentials

credentials = AppAssertionCredentials( scope='https://www.googleapis.com/auth/compute' )
HTTP = credentials.authorize(httplib2.Http(memcache))

compute = discovery.build('compute', 'v1', http=HTTP)

PROJECT_ID = "project-id"

INSTANCE = "json/rest body of instance parameters, this works"

class vmlaunchftp(webapp2.RequestHandler):
    def __init__(self, request=None, response=None):
        self.initialize(request, response)

    def get(self):
        request = compute.instances().insert(project=PROJECT_ID, body=INSTANCE, zone="us-central1-b" )
        response = request.execute(http=HTTP)


APPLICATION = webapp2.WSGIApplication([('/crons/ftpcronjob', vmlaunchftp)], debug=True)

的app.yaml

application: sh-vo-001
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
#cron job
- url: /crons/ftpcronjob
  script: vmlaunch.APPLICATION

#Endpoint handler
- url: .*
  script: main.APPLICATION

libraries:
- name: pycrypto
  version: latest
- name: endpoints
  version: 1.0
- name: webapp2
  version: "2.5.2"

cron.yaml

cron:
- description: vmlaunch.py 
  url: /crons/ftpcronjob
  schedule: every day 11:30
  timezone: America/Los_Angeles

我怀疑它失败了，因为来自request.exe的响应超时，但为什么它可以在网站上运行？

如何在不使用任务队列的情况下从appengine在VM上启动作业？

我们如何在没有足够实时更新日志文件的情况下调试此类问题？

编辑：添加了app.yaml，cron.yaml;适用于devserver，但凭据预期不好！

谷歌应用程序引擎cron作业无法正常工作，http超时？
