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DefaultHttpClientAndroidHttpClient),则可以使用函数setParams()

httpClient.setParams(httpParameters);
