我们在Heroku上构建并部署了一个应用程序,此应用程序上的某些进程已经开始超时,我迫切需要将它们移到后台进程。
我使用delayed_job完成了这项工作,并仔细按照Heroku文档中有关如何进行设置的步骤进行操作。在当地,这很好。
然而,在生产中,创建延迟的作业会抛出401.此错误似乎发生在我们的应用程序之外,即不在我们编写的代码中。我几乎完全被这个错误所困扰,因为它似乎处理了很多Heroku内部。我将在发生这些类型的错误时粘贴部分异常通知电子邮件。

我删除了其余的回溯。回溯中没有任何内容引用我们的应用程序中的任何内容。
任何帮助都将不胜感激。
以下是调查导出的代码 - 非常基本!
def export
@survey.delay.export(current_user.email)
flash[:notice] = "Your survey exports have been queued for processing and will be emailed to #{current_user.email} when complete."
redirect_to forge_surveys_path
end
答案 0 :(得分:9)
好的,我当然想到这一点 - 浏览回溯中调用的各种库的来源。
最相关的一句话:
vendor/bundle/ruby/1.9.1/gems/heroku-api-0.3.5/lib/heroku/api/processes.rb:9:in `get_ps'
这使用heroku-api gem来获取一些工作进程。浏览heroku-api gem的源代码,我看到当你通过API发出请求时,它会像这样初始化一个连接:
@api_key = options.delete(:api_key) || ENV['HEROKU_API_KEY']
if !@api_key && options.has_key?(:username) && options.has_key?(:password)
@connection = Excon.new("#{options[:scheme]}://#{options[:host]}", options.merge(:headers => HEADERS))
@api_key = self.post_login(options[:username], options[:password]).body["api_key"]
end
我的环境没有ENV['HEROKU_API_KEY']
设置。我确实拥有HEROKU_PASSWORD
集,其中包含相同的数据,但这并不是这个宝石所寻求的。因此,我得到了401错误。
我将提交Heroku文档的更新,并要求他们将此作为其中一个步骤,因为它现在不在那里。
要解决这个问题,我只是做了:
heroku config:add HEROKU_API_KEY=KEY
其中KEY与HEROKU_PASSWORD的值相同。 (您可以使用heroku config
查看所有配置变量。)
