文件流在Android到WCF [英] file streaming from Android to WCF

问题描述

我有以下合约：

[OperationContract(Name = "Upload")]
        [WebInvoke(Method = "POST", UriTemplate = "/Upload/{step}/{fileName}",
            BodyStyle= WebMessageBodyStyle.WrappedRequest)]
        Response FileUpload(string fileName, string step, Stream fileStream);

和实施

public Response FileUpload(string fileName, string step, Stream fileStream)
        {
            FileStream fileToUpload = new FileStream("C:\\inetpub\\wwwroot\\Upload\\" + fileName, FileMode.Create);

            byte[] bytearray = new byte[10000];
            int bytesRead, totalBytesRead = 0;
            do
            {
                bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
                totalBytesRead += bytesRead;
            } while (bytesRead > 0);

            fileToUpload.Write(bytearray, 0, bytearray.Length);
            fileToUpload.Close();
            fileToUpload.Dispose();

            Response res = new Response();
            res.Successful = true;
            res.Comment = "Bla bla";
            return res;
        }

和配置：

 <system.serviceModel>
    <client>
      <endpoint address="" binding="webHttpBinding"
                bindingConfiguration="StreamHTTP"
                contract="BillboardServices.IBillboardService"
      />
    </client>
    <bindings>
      <webHttpBinding>
        <binding name="StreamedHTTP"
                 transferMode="StreamedRequest"
                 maxReceivedMessageSize="10000000"
                 maxBufferSize="1000"
                 />

      </webHttpBinding>

    </bindings>

  </system.serviceModel>

当我打电话通过Android的HTTP请求的方法，我得到的状态code 400 - 错误的请求。
我有相同的Web服务，这是工作的其他方法。
我只是想不通问题出在哪里。

When I call the method through Android http request, I get status code 400 - Bad Request. I have other methods on the same web service, which are working. I just can't figure out where the problem is.

推荐答案

我设置一个测试服务器的基础上，code你已经张贴以上。

I setup a test server, based on the code you have posted above.

我执行使用招以下...

I executed the following using Fiddler...

的http：//本地主机：3333 /上传/步/文件名 HTTP / 1.1

POST http://localhost:3333/upload/step/filename HTTP/1.1

用户代理：提琴手

主持人：本地主机：3333

Host: localhost:3333

内容长度：11

<Foo></Foo>

和服务器上我调整你的code有点像这样...

And on the server I tweaked your code a bit to something like this...

 public string FileUpload(string fileName, string step, Stream fileStream)
    {
        StreamReader reader = new StreamReader(fileStream);
        Console.WriteLine(reader.ReadToEnd());
        return "Done";
    }

我没有issues.The code运行良好。

I had no issues.The code ran fine.

你确定你已经使用URI模板是没有得到冲突以或许一些其他的终点？ （通常WebGet）

Are you sure the URI template you have used is not getting conflicted with some other endpoint perhaps? (usually WebGet)
