如何在Java中为Android设置HttpResponse超时
我创建了以下函数来检查连接状态:
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());
...
当我关闭服务器以测试执行情况时,会在网上等待很长时间
HttpResponse response = httpClient.execute(method);
有谁知道如何设置超时以避免等待太久?
回答:
在我的示例中,设置了两个超时。连接超时抛出java.net.SocketTimeoutException: Socket is not connected
,套接字超时java.net.SocketTimeoutException: The operation timed out
。
HttpGet httpGet = new HttpGet(url);HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.
// The default value is zero, that means the timeout is not used.
int timeoutConnection = 3000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 5000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpResponse response = httpClient.execute(httpGet);
如果要设置任何现有HTTPClient的参数(例如DefaultHttpClient
或AndroidHttpClient)
,则可以使用函数setParams()
。
httpClient.setParams(httpParameters);
