httclient进行不间断的get请求产生错误

问题描述

我用apache的httpclient进行HttpGet请求，问题是我要不断进行轮询来检测URL是否能访问，超时时间设为1s，后来就发现很多正常的URL被检测为故障的。请问这是什么问题，怎么解决?下面是代码HttpClienthttpClient=newDefaultHttpClient();try{httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,1000);httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,1000);//创建httpUriRequest实例HttpGethttpGet=newHttpGet(urlStr);HttpResponsehttpResponse=httpClient.execute(httpGet);if(httpResponse.getStatusLine().getStatusCode()==200){return1;}httpGet.abort();}catch(Exceptione){e.printStackTrace();return0;}finally{//关闭连接，释放资源httpClient.getConnectionManager().shutdown();}return0;
