HttpURLConnection报错 找不到服务器上的文件

                        outputStream.close();
                    //    input.close();
                   //     connection.disconnect();

                    } catch (MalformedURLException e) {

                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                }
            }).start();

                            报错System.err: java.io.FileNotFoundException: http://www.9610.com/song/baiyuchan/baiyuchan.jpg
                              at com.android.okhttp.internal.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:207)
                                求指点哪里写错了？返回的connection.getResponseCode()是405 该称“GET”方法就可以了，但是想用“POST”来做要怎么修改呢？

这个图片只提供了GET请求，不支持POST去修改
