Question

我在Windows手机中创建了一个“csv文件”，我想在服务器中，在网络上发布它，我找不到我想要的方式，

我不想只使用参数发出“发布请求”，我想在服务器中发布我的文件...

实际上，我已连接到此服务器，但找不到我的文件......

public void SentPostReport()
    {


        //Post response.
        string url = this.CurentReportkPI.configXml.gw; // string url 
        Uri uri = new Uri(url);

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
        request.Accept = "application/CSV";
        request.Method = "POST";
        request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), request);
    }

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

        // End the operation
        Stream postStream = request.EndGetRequestStream(asynchronousResult);

        // I create My csv File 
        CreateCsv reportCsv = new CreateCsv();
        string pathReportFile = reportCsv.CreateNewReport(this.report);
        string CsvContent = reportCsv.ReadFile(pathReportFile);

        // Convert the string into a byte array.
        byte[] byteArray = Encoding.UTF8.GetBytes(CsvContent);

        // Write to the request stream.
        postStream.Write(byteArray, 0, byteArray.Length);
        postStream.Close();

        // Start the asynchronous operation to get the response
        request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);
    }


    private static void GetResponseCallback(IAsyncResult asynchronousResult)
    {
        Debug.WriteLine("GetResponseCallback");
        HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;

        // End the operation
        HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
        Stream streamResponse = response.GetResponseStream();
        StreamReader streamRead = new StreamReader(streamResponse);
        string responseString = streamRead.ReadLine();
        // Close the stream object
        streamResponse.Close();
        streamRead.Close();

        // Release the HttpWebResponse
        response.Close();
    }

在我继续解决我的问题时，您有什么想法，并根据我的请求发送我的CSV文件？

感谢。

Answer 1

不确定这是否是问题所在，但在POST请求中，您应该设置ContentLength和ContentType（“application / x-www-form-urlencoded”）标头等等......

请查看this“操作方法”关于完全正确的POST请求的文章 - 这不适用于Windows Phone，但我认为您仍然可以获得完整的意识形态！

另一方面，我建议您选择RestSharp来解决所有这些问题！

您可以使用AddFile方法使用RestSharp或Hammock轻松完成此操作。以下是我使用Hammock上传照片所做的一个示例：

var request = new RestRequest("photo", WebMethod.Post);
request.AddParameter("photo_album_id", _album.album_id);
request.AddFile("photo", filename, e.ChosenPhoto);
request.Client.BeginRequest(request, (restRequest, restResponse, userState) =>
    { 
        // handle response 
    }

使用Windows Phone 7在POST请求中发送文件
