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());
...
当我关闭服务器测试执行等待很长时间在行
HttpResponse response = httpClient.execute(method);
有人知道如何设置超时以避免等待太长时间吗?
谢谢!
HttpParams httpParameters = new BasicHttpParams();
HttpProtocolParams.setVersion(httpParameters, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(httpParameters,
HTTP.DEFAULT_CONTENT_CHARSET);
HttpProtocolParams.setUseExpectContinue(httpParameters, true);
// Set the timeout in milliseconds until a connection is
// established.
// The default value is zero, that means the timeout is not used.
int timeoutConnection = 35 * 1000;
HttpConnectionParams.setConnectionTimeout(httpParameters,
timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 30 * 1000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
一种选择是使用OkHttp客户端，来自Square。
添加库依赖项
在构建中。Gradle，包括这一行:
compile 'com.squareup.okhttp:okhttp:x.x.x'
其中x.x.x为所需的库版本号。
设置客户端
例如，如果你想设置一个60秒的超时，这样做:
final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);
ps:如果你的minSdkVersion大于8，你可以使用TimeUnit.MINUTES。所以，你可以简单地使用:
okHttpClient.setReadTimeout(1, TimeUnit.MINUTES);
okHttpClient.setConnectTimeout(1, TimeUnit.MINUTES);
有关单位的详细信息，请参见TimeUnit。
在我的示例中，设置了两个超时。连接超时抛出java.net.SocketTimeoutException:套接字未连接，套接字超时。
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);
如果你想设置任何现有HTTPClient(例如DefaultHttpClient或AndroidHttpClient)的参数，你可以使用函数setParams()。
httpClient.setParams(httpParameters);
