Question

我正在使用HttpWebRequest for Multipart Post以字节数组的形式将图像上传到服务器，我应该收到一个json字符串，其中包含响应中帖子的详细信息。但相比之下，我只得到一个响应代码“OK”作为响应，而不管帖子的成功与否。任何人都可以帮我解决这个问题。

我在帖子中使用以下代码。

Dictionary<string, object> postParam;


public void SubmitPost()
    {

        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(new Uri(url, UriKind.Absolute));
        myRequest.Method = "POST";
        myRequest.ContentType = string.Format("multipart/form-data; boundary={0}", boundary);
        myRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), myRequest);
    }


    public string url
    {
        get
        {

            return "URL";

        }
    }



    string boundary = "----------" + DateTime.Now.Ticks.ToString();


    private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
    {
        HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
        Stream postStream = request.EndGetRequestStream(asynchronousResult);


        writeMultipartObject(postStream, postParam);
        postStream.Close();

        request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);

    }
    string res;
    private void GetResponseCallback(IAsyncResult asynchronousResult)
    {
        HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
        HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);

        Stream streamResponse = response.GetResponseStream();

        StreamReader streamRead = new StreamReader(streamResponse);
        streamResponse.Close();
        streamRead.Close();

        res = response.StatusCode.ToString();

        response.Close();

    }

res的值总是“OK”

您需要阅读streamRead的回复。 StatusCode只是表示数据已上传。
