从 Rails 内容类型中删除字符集 [英] Remove charset from Rails content type

问题描述

当 Content-Type 包含字符集行时，我有一个老式的愚蠢服务向我的应用程序发出请求失败

I have a old-stupid service making request to my app that fails when the Content-Type include the charset line

Content-Type    text/html; charset=utf-8

而且我不知道如何从我的 rails 响应中删除它.每次我覆盖强制第一部分(内容类型文本/html)的标题时，Rails 都会将字符集添加到标题中...

and I don't know how to remove it from my rails response. Every time that I override the headers forcing just the first part (Content-Type text/html) Rails adds the charset to the header...

推荐答案

对于 Rails 3/4，处理这个的代码在 ActionDispatch::Response.assign_default_content_type_and_charset! 中的 actionpack/lib/action_dispatch/http/response.rb.

For Rails 3/4, the code that handles this is in ActionDispatch::Response.assign_default_content_type_and_charset! in actionpack/lib/action_dispatch/http/response.rb.

设置 response.headers['Content-Type'] 而不是 response.content_type 应该消除字符集.Chubas 的解决方案对所有响应执行此操作.

Setting response.headers['Content-Type'] instead of response.content_type should eliminate the charset. Chubas' solution does this for all responses.

对于 Rails 2，处理这个的代码位于 content_type= 和 charset= 中，actionpack/lib/action_controller/response.rb.

For Rails 2, the code that handles this is in content_type= and charset= in actionpack/lib/action_controller/response.rb.

正如 Carson 的解决方案所描述的，设置 ActionController::Base.default_charset = nil 应该消除字符集.

As Carson's solution describes, setting ActionController::Base.default_charset = nil should eliminate the charset.
