使用Sinatra更改HTTP状态消息 [英] Changing HTTP status message using Sinatra

问题描述

我正在编写一个简单的Sinatra应用程序，并且在用户发布带有特定数据的请求时，我想返回错误453（自定义错误代码），并显示消息CLIENT_ERROR或类似内容。

I'm writing a simple Sinatra app, and given a user posts a request with an specific data, I want to return an error '453' (custom error code) with a message CLIENT_ERROR, or something similar.

问题是：查看Sinatra文档并进行一些测试我找不到设置响应错误消息的方法，只有响应状态。

The problem is: looking into the Sinatra documentation and doing some testing I couldn't find a way to setup the response error message, only the response status.

所以，如果一套Sinatra回复

So, if a set the Sinatra response

get '/' do
   response.status = 453
end

我得到错误代码：

curl -v localhost:4567

* About to connect() to localhost port 4567 (#0)
*   Trying 127.0.0.1... connected
> GET / HTTP/1.1
> User-Agent: curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4     libidn/1.23 librtmp/2.3
> Host: localhost:4567
> Accept: */*
> 
< HTTP/1.1 453 
< X-Frame-Options: sameorigin
< X-XSS-Protection: 1; mode=block
< Content-Type: text/html;charset=utf-8
< Content-Length: 0
< Connection: keep-alive
< Server: thin 1.3.1 codename Triple Espresso
< 
* Connection #0 to host localhost left intact
* Closing connection #0

但我想要的是：

< HTTP/1.1 453 CLIENT_ERROR

与我的方式相同

< HTTP/1.1 200 OK

当一切按计划进行时。

无论如何使用Sinatra / Rack进行此操作？

Is there anyway to do this using Sinatra/Rack?

推荐答案

状态消息由你正在使用的服务器，例如在Thin中，消息在 Thin :: HTTP_STATUS_CODES ，响应行在 Thin :: Response ，在WEBrick中，它们位于 WEBrick :: HHTPStatus :: StatusMessage 并在 中生成响应WEBrick :: HTTPResponse 。

The status message is generated by the server you are using, e.g. in Thin the messages are in Thin::HTTP_STATUS_CODES and the reponse line is generated in Thin::Response, and in WEBrick they are in WEBrick::HHTPStatus::StatusMessage and the response is generated in WEBrick::HTTPResponse.

如果您知道正在使用的服务器，可以将错误添加到相应的哈希值。

If you know what server you are using, you could add your error to the appropriate hash.

使用Thin：

require 'thin'
Thin::HTTP_STATUS_CODES[453] = "Client Error"

和输出：

$ curl -v localhost:4567
* About to connect() to localhost port 4567 (#0)
*   Trying 127.0.0.1... connected
* Connected to localhost (127.0.0.1) port 4567 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.19.7 (universal-apple-darwin10.0) libcurl/7.19.7 OpenSSL/0.9.8r zlib/1.2.3
> Host: localhost:4567
> Accept: */*
> 
< HTTP/1.1 453 Client Error
< X-Frame-Options: sameorigin
< X-XSS-Protection: 1; mode=block
< Content-Type: text/html;charset=utf-8
< Content-Length: 0
< Connection: keep-alive
< Server: thin 1.4.1 codename Chromeo
< 
* Connection #0 to host localhost left intact
* Closing connection #0

和WEBrick：

require 'webrick'
WEBrick::HTTPStatus::StatusMessage[453] = "Client Error"

给出输出：

$ curl -v localhost:4567
* About to connect() to localhost port 4567 (#0)
*   Trying 127.0.0.1... connected
* Connected to localhost (127.0.0.1) port 4567 (#0)
