如何在 ruby 中发送原始标头

发布于 2024-07-25 07:38:24 字数 417 浏览 0 评论 0原文

我有一个使用 UTF-8 字符集的页面，但是页面上的字符被破坏了，我认为这只是设置标题“Content-Type: text/html; charset=utf-8”的问题。我知道如何在 PHP 中执行此操作，只需将以下内容放在页面顶部即可。

<?php header("Content-Type: text/html; charset=utf-8"); ?>

有没有办法在红宝石中做到这一点？你能像这样在页面顶部放置一个标题吗？

我不使用它作为 Rails 应用程序的一部分。它用于独立应用程序中的嵌入式浏览器页面，我可以使用 Javascript 和/或 Ruby 创建动态页面。

原文

I have a page which uses the UTF-8 character set, however the characters are mangled on the page, I think this is just a matter of setting a header "Content-Type: text/html; charset=utf-8" ... I know how to do this in PHP, simply place the following at the top of the page.

<?php header("Content-Type: text/html; charset=utf-8"); ?>

Is there a way to do this in ruby? Can you place a header at the top of a page, like that?

I'm not using this as part of a rails application. It is for an embedded browser page in a stand-alone application, I can use Javascript and/or Ruby to create dynamic pages.

您正在使用 Ruby on Rails 吗？

request.headers["Content-Type"] # => "text/plain"

或者也许是 Ruby 的 CGI 库？

Are you using Ruby on Rails?

request.headers["Content-Type"] # => "text/plain"

Or maybe Ruby's CGI library?

如果您使用 Rails，您需要：

response.content_type = Mime::HTML
response.charset      = "utf-8"

您还可以尝试直接设置标头：

response.headers["Content-Type"] = "text/html; charset=utf-8"

如果您使用 Rack，您希望使用元组的第二个元素设置标头：

class MyRackApp
  def call(env)
    response = []
    # do stuff with env, populating response
    # response is [status_code, headers, body]
    response[1]["Content-Type"] = "text/html; charset=utf-8"
    response
  end
end

如果您使用原始 CGI（我肯定会推荐 Rack 而不是 cgi.rb）：

header("text/html; charset=utf-8")

If you're using Rails, you want:

response.content_type = Mime::HTML
response.charset      = "utf-8"

You could also try to set the headers directly:

response.headers["Content-Type"] = "text/html; charset=utf-8"

If you're using Rack, you want to set the header using the second element of the tuple:

class MyRackApp
  def call(env)
    response = []
    # do stuff with env, populating response
    # response is [status_code, headers, body]
    response[1]["Content-Type"] = "text/html; charset=utf-8"
    response
  end
end

If you're using raw CGI (I would definitely recommend Rack over cgi.rb):
