当我们使用ASP.NETC#2.0时，我必须对其进行移植，但我总是会遇到一个不合理的错误

以下是我正在做的：

HttpWebRequest q = (HttpWebRequest)WebRequest.Create(Host + ":" + Port);
                ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(new interhanse().AcceptAllCertifications);                

                q.Method = "POST";
                q.Headers.Add("JSON-Signature:" + GetSignature(data));
                q.ContentType = "application/json";

                q.UseDefaultCredentials = false;
                q.Credentials = new NetworkCredential(user,pwd, Host);

                byte[] buffer = UTF8Encoding.UTF8.GetBytes(data);

                q.ContentLength = data.Length;                

                Stream oStream = q.GetRequestStream();
                StreamWriter oWriter = new StreamWriter(oStream);
                oWriter.Write(buffer);
                oWriter.Close();


                HttpWebResponse reps = q.GetResponse() as HttpWebResponse;

我已经阅读了所有关于这方面的问题，但是我没有得到任何改进。提前谢谢

有一件事你做错了，那就是假设字节长度与字符长度相同。您应该使用buffer.Length作为内容长度。您还调用了

StreamWriter。使用字节数组编写。您不应该这样做-您应该只使用流，因为您已经完成了编码：
byte[] buffer = Encoding.UTF8.GetBytes(data);

q.ContentLength = buffer.Length;
using (Stream stream = q.GetRequestStream())
{
    stream.Write(buffer, 0, buffer.Length);
}

现在，这并不能解决身份验证问题。您可能会发现，只需设置PreAuthenticate
即可解决以下问题：
q.PreAuthenticate = true;

如果这不起作用，我建议您运行并查看通过Curl的请求与来自.NET的请求之间的差异。

如果这不起作用，我建议您运行并查看通过Curl的请求与来自.NET的请求之间的差异。
我认为您不应该在身份验证中提供主机
q.Credentials = new NetworkCredential(user,pwd);

这大概是：
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Host + ":" + Port);
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(new interhanse().AcceptAllCertifications);

request.Method = "POST";
request.Headers.Add("JSON-Signature:" + GetSignature(data));
request.ContentType = "application/json";

request.UseDefaultCredentials = false;
request.Credentials = new NetworkCredential(user, pwd);

byte[] buffer = UTF8Encoding.UTF8.GetBytes(data);

request.ContentLength = buffer.Length;
using (Stream oStream = request.GetRequestStream()) {
    oStream.Write(buffer, 0, buffer.Length);
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
    // load data from response here
}

另外，您应该避免在每个请求上分配服务点验证委托，这可能会越来越慢请求，因为验证会执行多次，而且这也是一种内存泄漏。

下面是如何在Asp.Net中添加CURLOPT_USERPWD的：
    private async Task<string> Execute(string url, string query, string user, string pasword)
    {
        HttpClient httpClient = new HttpClient();
        var baseUri = new Uri(url, UriKind.Absolute);  // e.g. http://somedomain.com/endpoint
        Uri request = new Uri(baseUri, query);    // with query e.g. http://somedomain.com/endpoint?arg1=xyz&arg2=abc

        // Add a new Request Message
        HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Get, request);

        // add headers -> CURLOPT_USERPWD equivalent
        var encodedStr = Convert.ToBase64String(Encoding.Default.GetBytes(string.Format("{0}:{1}", user, password)));
        var authorizationKey = "Basic" + " " + encodedStr;    // Note: Basic case sensitive
        requestMessage.Headers.Add("Authorization", authorizationKey);

        // if POST - do this instead
        // content
        //HttpContent content = new StringContent(jsonContent);     // string jsonContent i.e. JsonConvert.SerializeObject(YourObject);
        //requestMessage.Content = content;
        //requestMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");

        // execute
        HttpResponseMessage responseMessage = await httpClient.SendAsync(requestMessage);
        var responseString = await responseMessage.Content.ReadAsStringAsync();    // reads it as string; 

        // if json and you need to convert to an object do this
        // var myresponse = JsonConvert.DeserializeObject<YourMappedObject>(responseString);

        return responseString;

谢谢，错误现在改为：“连接已终止。未过期的接收错误。”但由于它们是自定义错误，我现在将请求支持：D非常感谢！谢谢，错误现在改为：“连接终止。未过期的接收错误。”但由于它们是自定义错误，我现在将请求支持：D非常感谢！没有更改错误，但由于它不在示例中，我将不再通过它。没有更改错误，但由于它不在示例中，我将不再通过它。
