Question

我目前正在开发一个wcf服务，它需要通过实体框架从数据库中读取数据并将数据传回客户端（在我的情况下是Android）。该服务支持REST和SOAP。 wcf服务托管在Windows服务下。但是，我没有成功将流上传到WCF并将流数据从WCF服务下载到android。我只在下面显示将流数据上传到wcf服务的功能。

有谁知道为什么它不起作用？我试图将流式数据从android传递到wcf服务或从wcf服务传递到android。它们都不起作用。我用于WCF和android的代码如下：

webhttpbinding也支持流吗？

在我的WCF服务中，app.config位于以下位置：

    <?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

      </providers>
    </membership>
    <roleManager defaultProvider="ClientRoleProvider" enabled="true">

      </providers>
    </roleManager>

      <service behaviorConfiguration="ServBehave" name="iPhysio_Wcf_Service.Service">
        <host>
          <baseAddresses>
            <add baseAddress="http://xx.xxx.xxx.xxx:8733/iPhysio_Wcf_Service/Service/" />

        </behavior>

    </behaviors>
  </system.serviceModel>

      <remove invariant="System.Data.SQLite" />

  </connectionStrings>
  <appSettings>
    <add key="ClientSettingsProvider.ServiceUri" value="" />
  </appSettings>
</configuration>

服务接口的代码：

[OperationContract(Action = "UploadFile", IsOneWay = true)]
      [WebInvoke(Method = "POST", UriTemplate = "/Fileupload", BodyStyle = WebMessageBodyStyle.WrappedRequest)]
       void AddMonitoringData(Stream stream);

服务代码：

  public void AddMonitoringData(Stream stream)
        {
            StreamReader reader = new StreamReader(stream);
            string text = reader.ReadToEnd();

            File.AppendAllText("c:\\wcf_service\\test.txt", text);

        }

这是我在Java中用于将流数据发送到wcf服务的安卓代码：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        String xml ="valid xml here. Testing here.";
        InputStream is = new ByteArrayInputStream(xml.getBytes());

                // Send GET request to <service>/GetPlates

         String XMLURL = "http://xxxx:8733/iPhysio_Wcf_Service/Service/XMLService";
                HttpPost request = new HttpPost(XMLURL + "/Fileupload");
                request.setHeader("Accept", "binary/octet-stream");
                 request.setHeader("Content-type", "binary/octet-stream");
                 InputStreamEntity reqEntity = new InputStreamEntity(is, -1);
                 reqEntity.setContentType("binary/octet-stream");
                    reqEntity.setChunked(false); // Send in multiple parts if needed
                  request.setEntity(reqEntity);
                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpResponse response = httpClient.execute(request);

感谢您提前提供任何帮助。
