Rails HTTParty 获取超时::错误 [英] Rails HTTParty Getting Timeout::Error

问题描述

我有一个以 API 为中心的应用程序 (/api/v1/users)，它简单地以 JSON 格式返回所有用户.

I have an API centric application (/api/v1/users) it simply return all users restfully with JSON format.

我的问题是，如果我在控制器上调用该路由，它会返回Timeout::Error"有什么问题?

My problem is, if I call that route on the controller, it returns "Timeout::Error" What is the problem?

class BaseController < ApplicationController
  def index
    return HTTParty.get('http://localhost:3000/api/v1/users').body
  end
end

更新

• users_controller.rb (/api/v1/users)
• application_controller.rb

推荐答案

如果我理解正确，您有一个 API 端点，位于 /api/v1/users，以及您的 BaseController#index 正在调用该方法?

If I understand correctly, you have an API end-point, at /api/v1/users, and your BaseController#index is calling that method?

如果这是正确的，在同一个 rails 进程中，并且您正在开发模式下进行测试(我可以从您的 url 中看出)，那么您只有一个进程在运行，它一次只能处理一个请求.因此，如果您向 BaseController#index 发起请求，它将向您自己的测试服务器发起另一个请求，该服务器正忙，并且会一直等到超时.

If that is correct, inside the same rails process, and you are testing in development mode (as I can tell from your url), then you only have a single process running, which can only handle a single request at once. So if you start a request to BaseController#index, it will start another request to your own test-server, which is busy, and it will just wait until it times out.

如果您想测试您的 API，我会查看客户端工具，例如邮递员.

If you want to test your API, I would look at a client tool like e.g. Postman.

HTH.
