使用摘要式身份驗證的HttpClient發布請求導致錯誤請求-有解無憂

我正在使用以下代碼從大華 XVR 攝像機中提取記錄并成功回傳記錄。

        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));

但是當我使用以下代碼發布記錄時，它不起作用并導致請求錯誤。

        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);

上面的代碼總是回傳 400 個錯誤的請求。如果有人可以幫忙嗎？

uj5u.com熱心網友回復：

我解決了這個問題，如下所示。也許它可以幫助某人。

減小了我必須嵌入到請求正文中的影像的大小。

將 URL 和引數連接在一個字串中。

   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);
