App Engine Cron作业始终返回HTTP状态代码301 [英] App Engine Cron Job Always return HTTP status code 301

问题描述

我已遵循本指南为我的Rails应用程序创建cron作业，但是HTTP状态代码始终返回301，而我的作业状态失败。我是否缺少某些东西？

I have followed this guide to create cron job for my Rails app, but the HTTP status code is always returns 301 and my job status is failed. Am I missing something?

controller：

controller:

class CronsController < ApplicationController
  def example
    if request.headers["X-Appengine-Cron"]
      Example.do_something
      head :ok
    else
      head :not_found
    end
  end
end

路线：

get 'crons/example', to: 'crons#example'

cron.yaml

cron.yaml

cron:
  - description: my cron example
  url: /crons/example
  schedule: every 2 hours from 03:00 to 07:00

从 gcloud应用程序日志读取的结果

2017-08-26 07:00:05 default[20170823t153316]  "GET /crons/example" 301

推荐答案

两种可能性，两种都存在，因为应用引擎cron不遵循重定向：

Two possibilities, both issues because app engine cron does not follow redirects:

• Does Rails默认添加尾部斜线到路由？我在Django上也遇到了同样的问题，这就是原因。我在cron.yaml中更新了路由，以包括尾斜杠（在您的情况下为 url：/ crons / example / ），并进行了修复。


• 您的应用程序是否重定向到https？如果是这样，您可能需要免除此路线。

• Does Rails add trailing slashes to routes by default? I had the same issue with Django and this turned out to be the cause. I updated the route in cron.yaml to include the trailing slash (in your case url: /crons/example/) and that fixed it.
• Is your application redirecting to https? If so, you may need to exempt this route.
