原因分析:
1.客户端与服务器的链接已经关闭(可能是客户端,也可能使服务器端,一般是客户端主动关闭),客户端继续向服务端写数据;
2.在使用httpclient的threadsafeconnectionmanager或者poolconnectionmanger的时候容易出现,原因是我们设置了连接获取数据超时的时间;
解决方法:
1.为你的httpclient添加retry handler,形如下代码:
HttpRequestRetryHandler retryHandler = new HttpRequestRetryHandler() { @Override public boolean retryRequest(IOException arg0, int arg1, HttpContext arg2) { // retry a max of 5 times if (arg1 >= 3) { return false; } if (arg0 instanceof ch.boye.httpclientandroidlib.NoHttpResponseException) { return true; } else if (arg0 instanceof ch.boye.httpclientandroidlib.client.ClientProtocolException) { return true; } return false; } }; sHttpClient.setHttpRequestRetryHandler(retryHandler);
2.处理SocketException:
InputStream in = null; try { final HttpResponse response = HttpManager.execute(context, post); final int statusCode = response.getStatusLine().getStatusCode(); if (statusCode == HttpStatus.SC_OK) { HttpEntity entity = response.getEntity(); if (entity != null) { in = entity.getContent(); return IOUtils.stream2String(in); } } else { post.abort(); mLog.error("http code: " + response.getStatusLine().getStatusCode()); } } catch (IOException ex) { post.abort(); } catch (RuntimeException ex) { post.abort(); throw ex; } finally { IOUtils.closeStream(in); }SocketExcption是IOException的子类,当发现有IO异常的时候主动关闭该连接,而又httpClient去重试进行连接;
