Java Android未连接到在浏览器中工作的WCF服务

我有一个WCF服务（在浏览器中尝试了它）它的代码

[OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "Login/?username={username}&password={password}")]
    bool Login(string username, string password);

    [OperationContract]
    [WebGet(UriTemplate = "Search/?query={query}&type={type}", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
    List<AndroidBook> Search(string query, int type);

这是正确的，但在尝试使用以下代码连接android客户端时：

try {
                        HttpClient httpclient = new DefaultHttpClient();
                        HttpResponse response = httpclient.execute(new HttpGet(urls));
                        StatusLine statusLine = response.getStatusLine();
                        if(statusLine.getStatusCode() == HttpStatus.SC_OK){
                            ByteArrayOutputStream out = new ByteArrayOutputStream();
                            response.getEntity().writeTo(out);
                            out.close();
                            String responseString = out.toString();
                            //..more logic
                        } else{
                            //Closes the connection.
                            response.getEntity().getContent().close();
                            throw new IOException(statusLine.getReasonPhrase());
                        }
                    } catch (IOException e) {
                        Log.e("HTTP GET:", e.toString());
                    }

我遇到了

filenotfound

的异常，或者当我收到外部代码的响应时，我收到了一个

错误的请求

，我在谷歌上搜索了这个问题，遇到了同样的问题，并阅读了以下文章



使用fiddler，我在JSON中得到了正确的响应

任何帮助都将不胜感激：）

您是否在android中使用了asynctask或用于网络操作的线程？@IllegalArgument我读到了关于

asynctask

，但出于测试目的，我在android代码

StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder（）.permitAll（）.build（）中添加了以下内容：；StrictMode.setThreadPolicy（策略）{"LoginResult":true}

try {
                        HttpClient httpclient = new DefaultHttpClient();
                        HttpResponse response = httpclient.execute(new HttpGet(urls));
                        StatusLine statusLine = response.getStatusLine();
                        if(statusLine.getStatusCode() == HttpStatus.SC_OK){
                            ByteArrayOutputStream out = new ByteArrayOutputStream();
                            response.getEntity().writeTo(out);
                            out.close();
                            String responseString = out.toString();
                            //..more logic
                        } else{
                            //Closes the connection.
                            response.getEntity().getContent().close();
                            throw new IOException(statusLine.getReasonPhrase());
                        }
                    } catch (IOException e) {
                        Log.e("HTTP GET:", e.toString());
                    }
