我需要为我正在编写的一些测试创建 Http POST 请求和一些 GET 请求作为字符串。目前，我的测试使用 StringBuilder 构建它们，并且从 fiddler 中提取的硬编码 POST 请求有点像这样：

var builder = new StringBuilder();
builder.Append("POST https://some.web.pg HTTP/1.1\r\n");
builder.Append("Content-Type: application/x-www-form-urlencoded\r\n");
builder.Append("Referer: https://some.referer.com\r\n");
builder.Append("Accept-Language: en-us\r\n");
builder.Append("Accept-Encoding: gzip, deflate\r\n");
builder.Append("User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)\r\n");
builder.Append("Host: login.yahoo.com\r\n");
//    ... other header info
builder.Append("\r\n");
builder.Append("post body......\r\n");
var postData = builder.ToString();

这很快使我的测试变得混乱，并且希望有一种更简洁的方式来构建这些 POST 请求。我一直在研究 HttpWebRequest 类，希望它可以为我创建这些。我认为，它必须有某种方式来构建这个我试图以某种形式创建的确切请求。但可惜的是，GetRequestStream 是一个只可写的流。

有没有办法读取 HttpWebRequest 将生成的请求流（然后将其更改为字符串）？甚至任何关于如何生成这些 POST 请求的想法都可以。

这里有一个 msdn 示例来发出 Get 请求：

using System;

使用 System.Net；使用 System.IO；

namespace MakeAGETRequest_charp { /// /// Class1 的摘要描述。/// 类 Class1 { static void Main(string[] args) { string sURL; sURL = " http://www.microsoft.com ";

        WebRequest wrGETURL;
        wrGETURL = WebRequest.Create(sURL);

        WebProxy myProxy = new WebProxy("myproxy",80);
        myProxy.BypassProxyOnLocal = true;

        wrGETURL.Proxy = WebProxy.GetDefaultProxy();

        Stream objStream;
        objStream = wrGETURL.GetResponse().GetResponseStream();

        StreamReader objReader = new StreamReader(objStream);

        string sLine = "";
        int i = 0;

        while (sLine!=null)
        {
            i++;
            sLine = objReader.ReadLine();
            if (sLine!=null)
                Console.WriteLine("{0}:{1}",i,sLine);
        }
        Console.ReadLine();
    }
}

这里是一个 for post 请求（来自带有 post 的 HTTP 请求）

    HttpWebRequest httpWReq =
    (HttpWebRequest)WebRequest.Create("http:\\domain.com\page.asp");

ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "username=user";
postData += "&password=pass";
byte[] data = encoding.GetBytes(postData);

httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
httpWReq.ContentLength = data.Length;

using (Stream newStream = httpWReq.GetRequestStream())
{
    newStream.Write(data,0,data.Length);
}

我建议您使用模拟，因为它是单元测试的最佳实践：请参阅此答案 on stack Unit testing HTTP requests in c#

    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(yoururllink);
    var c = HttpContext.Current;

    //Set values for the request back
    req.Method = "POST";
    req.ContentType = "application/x-www-form-urlencoded";
    byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
    string strRequest = Encoding.ASCII.GetString(param);
    string strResponse_copy = strRequest;  //Save a copy of the initial info sent from your url link
    strRequest += "&cmd=_notify-validate";
    req.ContentLength = strRequest.Length;

    //for proxy
    //WebProxy proxy = new WebProxy(new Uri("http://url:port#"));
    //req.Proxy = proxy;

    //Send the request to PayPal and get the response
    StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
    streamOut.Write(strRequest);
    streamOut.Close();
    StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
    string strResponse = streamIn.ReadToEnd();
    streamIn.Close();
