            String httpUrl = "http://192.168.1.7:7086/upload/up";
            // HttpGet连接对象

            MultipartEntity mEntity=new MultipartEntity(); 
            
            ContentBody cbFile=new FileBody(new File(filename));
            mEntity.addPart("file1", cbFile);
            mEntity.addPart("fname", new StringBody("这是一个几吧文件","text/plan", Charset.forName("utf-8")));
            
            
            httpRequest.setEntity(mEntity);
            
            
            
            // 请求HttpClient，取得HttpResponse
            HttpResponse httpResponse = httpClient.execute(httpRequest,httpContext);
        
            // 请求成功
            if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                // 取得返回的字符串
                String strResult = EntityUtils.toString(httpResponse.getEntity());
                httpClient.getConnectionManager().shutdown();
                return strResult;
            } 
            throw new RuntimeException("网络请求执行错误!");
            
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
