C# httpwebrequest请求的顺序

我使用HttpWebRequest在c中发送请求#

请求应如下所示：

POST https://website.com/file HTTP/1.1
Host: api.website.com
User-Agent: useragent
Content-Length: 81
Accept: */*
Accept-Language: en;q=1, fr;q=0.9, de;q=0.8, ja;q=0.7, nl;q=0.6, it;q=0.5
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Accept-Encoding: gzip, deflate
Connection: keep-alive

POST https://website.com/file HTTP/1.1
Accept-Encoding: gzip, deflate
Accept-Language: en;q=1, fr;q=0.9, de;q=0.8, ja;q=0.7, nl;q=0.6, it;q=0.5
User-Agent: useragent
Accept: */*
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Host: api.website.com
Content-Length: 97
Connection: Keep-Alive

但它是这样表现的：

POST https://website.com/file HTTP/1.1
Host: api.website.com
User-Agent: useragent
Content-Length: 81
Accept: */*
Accept-Language: en;q=1, fr;q=0.9, de;q=0.8, ja;q=0.7, nl;q=0.6, it;q=0.5
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Accept-Encoding: gzip, deflate
Connection: keep-alive

POST https://website.com/file HTTP/1.1
Accept-Encoding: gzip, deflate
Accept-Language: en;q=1, fr;q=0.9, de;q=0.8, ja;q=0.7, nl;q=0.6, it;q=0.5
User-Agent: useragent
Accept: */*
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Host: api.website.com
Content-Length: 97
Connection: Keep-Alive

我试图搜索如何更改httpwebrequest的顺序，但找不到任何内容。

如果您的服务器依赖于标题的顺序，我认为它已损坏。我不希望顺序是有保证的或有意义的-为什么你的代码对它敏感？你不会改变标题的顺序吗？为什么这么重要？web服务器有一个安全检查来检查头的顺序。所以我必须保持这种方式。向他们展示RFC的这一部分：。的副本，答案是：不，如果您确实需要，请使用套接字自己编写HTTP客户端。
