覆盖HTTP响应状态文本

Question

How can I override in Tomcat 7 the text of the HttpStatu s.

I'm using HttpServletResponse.sendError(401, "Invalid username or Password") , but when I'm looking at the response status in the client it goves 401 Unauthorized .

Is there any way to override it?

Answer 1

Tomcat no longer supports USE_CUSTOM_STATUS_MSG_IN_HEADER property.

Changelog from 8.5.0 :

RFC 7230 states that clients should ignore reason phrases in HTTP/1.1 response messages. Since the reason phrase is optional, Tomcat no longer sends it. As a result the system property org.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER is no longer used and has been removed. (markt)

RFC 7230, Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing , June 2014. Section 3.1.2 :

The reason-phrase element exists for the sole purpose of providing a textual description associated with the numeric status code, mostly out of deference to earlier Internet application protocols that were more frequently used with interactive text clients. A client SHOULD ignore the reason-phrase content .

Answer 2

否 - 响应代码根据RFC 2616设置。如果要将消息传递给用户（到API客户端），请将其写入正文或响应头中

Answer 3

Edit catalina.properties and add the property:

org.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true

With that set in my dev environment, then when I do:

response.sendError(HttpServletResponse.SC_BAD_REQUEST, 
                   "A very very very bad request");

I see:

HTTP/1.1 400 A very very very bad request
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Language: en
Content-Length: 1024
