为了检查网络连接的情况,我创建了下边的方法:
private void checkConnectionStatus() {
HttpClient httpClient = new DefaultHttpClient();
try {
String url = "http://xxx.xxx.xxx.xxx:8000/GaitLink/"
+ strSessionString + "/ConnectionStatus";
Log.d("phobos", "performing get " + url);
HttpGet method = new HttpGet(new URI(url));
HttpResponse response = httpClient.execute(method);
if (response != null) {
String result = getResponse(response.getEntity());
...
当我关闭服务器来测试执行的时候,需要等待很长的时间
HttpResponse response = httpClient.execute(method);
有人知道怎么设置超时来避免等待太长的时间吗?
谢谢!
在我的示例中有两个超时的设置。连接超时声明抛出异常"java.net.SocketTimeoutException: Socket is not connected",Socket超时是"java.net.SocketTimeoutException: The operation timed out".
HttpGet httpGet = new HttpGet(url);
HttpParams httpParameters = new BasicHttpParams();
int timeoutConnection = 3000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
int timeoutSocket = 5000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpResponse response = httpClient.execute(httpGet);
如果你想给任何存在的HTTPClient(如DefaultHttpClient 或AndroidHttpClient)设置参数,你可以使用 setParams()方法。
httpClient.setParams(httpParameters);
如果你使用Jakarta的http client library ,那么你可以这样做:
HttpClient client= new HttpClient();
client.getParams().setParameter(HttpClientParams.CONNECTION_MANAGER_TIMEOUT, new Long(5000));
client.getParams().setParameter(HttpClientParams.SO_TIMEOUT, new Integer(5000));
GetMethod method= new GetMethod("http://www.yoururl.com");
method.getParams().setParameter(HttpMethodParams.SO_TIMEOUT, new Integer(5000));
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
int statuscode= client.executeMethod(method);
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
