【中文标题】具有摘要身份验证的 HttpClient 发布请求导致错误请求

【英文标题】：HttpClient post request with Digest Authentication results in bad request

【问题描述】：

我正在使用以下代码从大华XVR相机中提取记录，并成功返回记录。

        var domain = "http://IP";
        var credCache = new CredentialCache();
        credCache.Add(new Uri(domain), "Digest", new 
        NetworkCredential(username, password));
        var httpClient = new HttpClient(new HttpClientHandler  
        Credentials = credCache );
        var result= await httpClient.GetStringAsync(new Uri(URL));   

但是当我使用以下代码发布记录时，它不起作用并导致错误的请求。

        string url = "http://IP/cgi-bin/faceRecognitionServer.cgi";

        var postData = new List<KeyValuePair<string, string>>()
        
        new KeyValuePair<string, string>( "action", "addPerson"),
        new KeyValuePair<string, string>("groupID", "1"),
        new KeyValuePair<string, string>("name", "Test Name"),
        new KeyValuePair<string, string>("birthday", "1980-01-05"),
        new KeyValuePair<string, string>("sex", "Male"),
        new KeyValuePair<string, string>("country", "Pakistan"),
        new KeyValuePair<string, string>("province", "KPK"),
        new KeyValuePair<string, string>("city", "Peshawar")
        ;
        var content = new FormUrlEncodedContent(postData);

        var domain = "http://IP";
        var credCache = new CredentialCache();
        credCache.Add(new Uri(domain), "Digest", new NetworkCredential(username, password));
        var httpClient = new HttpClient(new HttpClientHandler  Credentials = credCache );
        var result = await httpClient.PostAsync(new Uri(url), content);

上面的代码总是返回 400 bad request。有人可以帮忙吗？

【问题讨论】：

问题可能与url有关

【参考方案1】：

我解决了如下问题。也许它可以帮助某人。

减小了我必须在请求中嵌入的图像的大小 身体。

将 URL 和参数连接在一个字符串中。

   string url = "http://IP/cgi-bin/faceRecognitionServer.cgi? 
                action=addPerson&groupID=1&name=TestName&sex=Male";

  string domain = "http://IP";
  CredentialCache credCache = new CredentialCache 
        
         new Uri(domain), "Digest", new NetworkCredential(username, 
         password)
        
    ;
 using HttpClient client = new HttpClient(new HttpClientHandler  
 Credentials = credCache );

 using FileStream stream = 


File.OpenRead(AppContext.BaseDirectory.
Replace("\\bin\\Debug\\netcoreapp3.1", "") + "Files\\14.jpg");

var file_content = new ByteArrayContent(new StreamContent(stream).ReadAsByteArrayAsync().Result);
    file_content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
    var response = await client.PostAsync(url, file_content);
