Webrick/Rails - 发送 POST 请求后超时错误

Question

我正在开发一个 Redmine 插件，我创建了一个方法，我发送 2 个 HTTP POST 请求以将文件附加到文档。

执行第一个请求后，我得到一个Timeout::Error (Timeout::Error)，虽然请求已经成功完成，但这是来自Webrick的错误代码

Timeout::Error (Timeout::Error): 
/usr/local/lib/ruby/1.9.1/net/protocol.rb:146:in `rescue in rbuf_fill' 
/usr/local/lib/ruby/1.9.1/net/protocol.rb:140:in `rbuf_fill'

Started POST "/uploads.json?attachment_id=1&filename=testFile.txt" for <server_IP_address> at 2014-04-02 09:15:28 +0200 
Processing by AttachmentsController#upload as JSON 
Parameters: {"attachment_id"=>"1", "filename"=>"testFile.txt"} 
Current user: <user> (id=3) 
Saving attachment '/home/user/Redmine/redmine-2.4.2/files/2014/04/140402091528_testFile.txt' (72 bytes) 
Rendered attachments/upload.api.rsb (1.7ms) 
Completed 201 Created in 87.9ms (Views: 7.9ms | ActiveRecord: 11.4ms)

您可以看到我在响应中得到了 201 状态，因此它起作用了，但是我有这个超时错误并且执行在那里停止。

这是我的代码：

uri = URI.parse("http://<server_IP_address>:3000/uploads.json")

http = Net::HTTP.new(uri.host, uri.port)
@file = File.new("/home/testFile.txt")
@csrfToken = session[:_csrf_token]

request = Net::HTTP::Post.new(@uri.path+"?attachment_id=1&filename=testFile.txt", initheader = {'Content-Type' => "application/octet-stream", 'X-CSRF-Token' => @csrfToken, 'X-Redmine-API-Key' => "my_key"})
request.body = @file.read
@response = http.request(request)

@upToken = @response.body

@secondResponse = RestClient.post 'http://<server_IP_address>:3000/documents/150/add_attachment', {:multipart => true, :utf8 => "\u2713", :authenticity_token => @csrfToken, :attachment => { "1" => {:filename => "testFile.txt", :description => "Dropbox blabla", :token => @upToken}}, :commit => "Add"}, :'X-Redmine-API-Key' => "mykey"

我也尝试过使用 Apache Web 服务器，第一个请求运行良好，我只在 Webrick 服务器上运行 Redmine 时遇到了这个问题。

你知道这个错误是从哪里来的吗？我该如何摆脱它？

您需要做的是您需要更改 webrick 服务器中的请求超时值，以便检查此问题的答案： how to set request timeout in rails ( thin or webrick server)
