安卓使用WCF的Restful形式上传文件

//安卓部分的代码public class UploadFile {	public static void toUploadFile(String url, String path) throws FileNotFoundException {		try {			// 1,读出文件到byte[]			InputStream is = new FileInputStream(path);			ByteArrayOutputStream os = new ByteArrayOutputStream();			byte[] buff = new byte[1024]; // buff用于存放循环读取的临时数据			int rc = 0;			while ((rc = is.read(buff, 0, 1024)) > 0) {				os.write(buff, 0, rc);			}			ByteArrayEntity reqEntity = new ByteArrayEntity(os.toByteArray());			reqEntity.setContentType("binary/octet-stream");			reqEntity.setChunked(true);			// 2, 初始化Post, 添加参数			HttpPost httpPost = new HttpPost(url);			httpPost.setHeader("charset", HTTP.UTF_8);			httpPost.setHeader("Accept", "application/json");			httpPost.setHeader("Content-Type", "binary/octet-stream");			httpPost.setEntity(reqEntity);			DefaultHttpClient client = getHttpClient();			HttpResponse response = client.execute(httpPost);// 上传文件			int statusCode = response.getStatusLine().getStatusCode();			if (statusCode == 200) {				System.out.println("调用成功: statusCode : " + statusCode);				return;			} else {				System.out.println("调用失败：code=" + statusCode);				return;			}		} catch (ClientProtocolException e) {			System.out.println(e.toString());		} catch (IOException e) {			System.out.println(e.toString());		} catch (Exception e) {			System.out.println(e.toString());		}	}	protected static DefaultHttpClient getHttpClient() {		DefaultHttpClient client = new DefaultHttpClient();		client.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 300);// 连接时间		client.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 3600 * 1000);// 超时时间		return client;	}}//WCF部分的代码[WebInvoke(UriTemplate = "ReceiveImg2", Method = "POST")]public string ReceiveImg2(Stream request){	try	{		string path = System.Web.Hosting.HostingEnvironment.MapPath("~") + "1.jpg";		using (var file = File.Create(path))		{			request.CopyTo(file);		}		return "1";	}	catch	{		return "-1";	}}web.Config里面 basicHttpBinding 的配置<basicHttpBinding>	<binding name="DocumentExplorerServiceBinding"			 sendTimeout="00:10:00"			 transferMode="Streamed"			 messageEncoding="Text"			 textEncoding="utf-8"			 maxReceivedMessageSize="9223372036854775807">	</binding></basicHttpBinding>
