How to set HttpResponse timeout for Android in Java
I have created the following function for checking the connection status:
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());
...
When I shut down the server for testing the execution waits a long time at line
HttpResponse response = httpClient.execute(method);
Does anyone know how to set the timeout in order to avoid waiting too long?
Thanks!
In my example two timeouts are set. The connection timeout throws "java.net.SocketTimeoutException: Socket is not connected" and the socket timeout "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);
If you want to set the Parameters of any existing HTTPClient (eg DefaultHttpClient or AndroidHttpClient) you can use the function setParams() .
httpClient.setParams(httpParameters);
To set settings on the client:
AndroidHttpClient client = AndroidHttpClient.newInstance("Awesome User Agent V/1.0");
HttpConnectionParams.setConnectionTimeout(client.getParams(), 3000);
HttpConnectionParams.setSoTimeout(client.getParams(), 5000);
I've used this successfully on JellyBean, but should also work for older platforms ....

如果您正在使用雅加达的http客户端库，那么您可以执行如下操作：
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);
