在.NET中是否可以将原始HTTP请求转换为HTTPWebRequest对象?
我确信.NET在内部做到了。知道.NET的哪个部分实际上正在处理这个问题?我可以调用它还是有任何允许原始HTTP连接的外部库?

我不相信有一种暴露的方法可以做到这一点。您可能必须找到或编写解析器以中断请求,然后编写自己的扩展HttpWebRequest的类。
以下是CodeProject的解析器:

我查看了HttpWebRequest的转子代码(简要地说),我没有看到任何突出的银弹。这是文件的链接:

所有转子代码都可以在线浏览:

在这里你可以下载它:
我知道一堆链接并没有真正回答你的问题,但我不认为你正在寻找的功能是在框架中公开的。我希望被证明是错误的,所以如果你找到了一个很好的方法,请更新帖子。我知道那里的工具必须这样做,任何用.Net写的记录原始请求的东西,然后让你重新提交它们就是做类似的事情。我相信 fiddler (http://www.fiddler2.com)是用.Net编写的,你可能想要发送电子邮件给那些人,看看他们是否可以提供帮助。

Google for Cassinni,它是一个HTTP服务器,其源代码最初由Microsoft提供,可以托管ASP.NET调用。你必须自己解析请求并加载它,但Cassinni将是一个很好的起点。此网址可能有所帮助:

Its possible now, but only with .Net Core 2.0+. Use Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpParser class:
using Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http;
using System;
using System.Buffers;
using System.Collections.Generic;
using System.Text;
public class Program : IHttpRequestLineHandler, IHttpHeadersHandler
{
public static void Main(string[] args)
{
string requestString =
@"POST /resource/?query_id=0 HTTP/1.1
Host: example.com
User-Agent: custom
Accept: */*
Connection: close
Content-Length: 20
Content-Type: application/json
{""key1"":1, ""key2"":2}";
byte[] requestRaw = Encoding.UTF8.GetBytes(requestString);
ReadOnlySequence<byte> buffer = new ReadOnlySequence<byte>(requestRaw);
HttpParser<Program> parser = new HttpParser<Program>();
Program app = new Program();
Console.WriteLine("Start line:");
parser.ParseRequestLine(app, buffer, out var consumed, out var examined);
buffer = buffer.Slice(consumed);
Console.WriteLine("Headers:");
parser.ParseHeaders(app, buffer, out consumed, out examined, out var b);
buffer = buffer.Slice(consumed);
string body = Encoding.UTF8.GetString(buffer.ToArray());
Dictionary<string, int> bodyObject = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<string, int>>(body);
Console.WriteLine("Body:");
foreach (var item in bodyObject)
Console.WriteLine($"key: {item.Key}, value: {item.Value}");
Console.ReadKey();
}
public void OnHeader(Span<byte> name, Span<byte> value)
{
Console.WriteLine($"{Encoding.UTF8.GetString(name)}: {Encoding.UTF8.GetString(value)}");
}
public void OnStartLine(HttpMethod method, HttpVersion version, Span<byte> target, Span<byte> path, Span<byte> query, Span<byte> customMethod, bool pathEncoded)
{
Console.WriteLine($"method: {method}");
Console.WriteLine($"version: {version}");
Console.WriteLine($"target: {Encoding.UTF8.GetString(target)}");
Console.WriteLine($"path: {Encoding.UTF8.GetString(path)}");
Console.WriteLine($"query: {Encoding.UTF8.GetString(query)}");
Console.WriteLine($"customMethod: {Encoding.UTF8.GetString(customMethod)}");
Console.WriteLine($"pathEncoded: {pathEncoded}");
}
}
Output:
Start line:
method: Post
version: Http11
target: /resource/?query_id=0
path: /resource/
query: ?query_id=0
customMethod:
pathEncoded: False
Headers:
Host: example.com
User-Agent: custom
Accept: */*
Connection: close
Content-Length: 20
Content-Type: application/json
Body:
key: key1, value: 1
key: key2, value: 2
