Get header values in ASP.NET MVC
提问by Aaron
I have a requirement to capture the HTTP User Agent header coming in from a device, take the value and remove a 'uuid'This UUID can then be used to direct the device to the correct location to give it the files relevant to the device.
我需要捕获来自设备的 HTTP 用户代理标头，获取值并删除“uuid”，然后可以使用此 UUID 将设备定向到正确的位置，以提供与设备相关的文件。
In webforms I was able to get it using
在网络表单中，我能够使用它
Request.ServerVariables["HTTP_USER_AGENT"]; //inside of Page_Load method
How would I go about this in MVC? I'm still learning MVC2 so please bear with me :-)
我将如何在 MVC 中解决这个问题？我还在学习 MVC2，所以请耐心等待 :-)
Thanks in advance,

if in controller, you can easily get the header by this:
如果在控制器中，您可以通过以下方式轻松获取标题：
Request.Headers.GetValues("XXX");
if the name does not exist, it will throw an exception.
如果名称不存在，则会抛出异常。

It should be in the Request.Headersdictionary.
Request.Headers字典里应该有。

如果有像我这样的人，专门通过 Google 搜索查看如何获取Content-TypeHTTP 请求标头，这很容易：
Request.ContentType
