Strange Timeout :: Controller Action中的render_to_string和HTTParty出错

标签: ruby-on-rails httparty

在我的控制器操作中,我使用带有jbuilder模板的render_to_string来向API呈现http post操作的对象,此API-Call的结果应该由控制器呈现。

但是我得到一个奇怪的超时然后我通过render_to_string渲染模型后调用HTTParty。

日志:

[23:43:52.262] [18033] [info]   Rendered admin/companies/companies.json.jbuilder (42.8ms)
... nothing happens here (60s timeout)

[23:44:52.466] [18033] [info] Response is {"status":"success"}

控制器 - 动作:

json_string = render_to_string(:template => '/admin/companies/companies', :formats => [:json],locals: { company: @company })
api_action = "/api/v1/internal/company/create_company_copy.json"
urlstring_to_post = 'http://localhost:3000'+ api_action
@result = HTTParty.post(urlstring_to_post.to_str, :body => JSON.parse(json_string))
render(:show, :formats => [:html])

对我来说奇怪的是,你可以在日志中看到实际的控制器操作由于超时而失败,因此错误被呈现给用户,但是发布到API的帖子已成功执行但仅在超时。

任何建议都赞赏!

常见问题,但如果太靠近监视器则很难跟踪。

我猜你运行rails server通常会启动一个WEBrick服务器进程。

不幸的是,你会在本地测试时阻止自己。

修复:启动另一个具有不同端口号的rails服务器。或者启动类似独角兽的东西,并将工人号码设置为2或更多。
