Cómo configurar HttpResponse timeout para Android en Java


He creado la siguiente función para comprobar el estado de la conexión:

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());
        ...

Cuando apago el servidor para probar la ejecución espera mucho tiempo en la línea

HttpResponse response = httpClient.execute(method);

¿Alguien sabe cómo establecer el tiempo de espera para evitar esperar demasiado tiempo?

Gracias!

En mi ejemplo se establecen dos tiempos de espera. El tiempo de espera de conexión arroja "java.net.SocketTimeoutException: Socket is not connected" y el tiempo de espera del socket "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);

Si desea establecer los Parámetros de cualquier HttpClient existente (por ejemplo, DefaultHttpClient o AndroidHttpClient) puede usar la función setParams().

httpClient.setParams(httpParameters);

Para establecer la configuración en el cliente:

AndroidHttpClient client = AndroidHttpClient.newInstance("Awesome User Agent V/1.0");
HttpConnectionParams.setConnectionTimeout(client.getParams(), 3000);
HttpConnectionParams.setSoTimeout(client.getParams(), 5000);

He usado esto con éxito en JellyBean, pero también debería funcionar para plataformas más antiguas ....

Si estás usando la biblioteca de cliente http de Yakarta entonces puedes hacer algo como:

        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);

Si está utilizando el cliente http predeterminado, aquí le mostramos cómo hacerlo utilizando los parámetros http predeterminados:

HttpClient client = new DefaultHttpClient();
HttpParams params = client.getParams();
HttpConnectionParams.setConnectionTimeout(params, 3000);
HttpConnectionParams.setSoTimeout(params, 3000);

Para aquellos que dicen que la respuesta de @kuester2000 no funciona, tenga en cuenta que las solicitudes HTTP, primero intente encontrar la IP del host con una solicitud DNS y luego realice la solicitud HTTP real al servidor, por lo que también puede necesitar establecer un tiempo de espera para la solicitud DNS.

Si su código funcionó sin el tiempo de espera para la solicitud DNS es porque puede llegar a un servidor DNS o está golpeando la caché DNS de Android. Por cierto, puede borrar esta caché reiniciando el dispositivo.

Este código extiende la respuesta original para incluir una búsqueda manual de DNS con un tiempo de espera personalizado:

//Our objective
String sURL = "http://www.google.com/";
int DNSTimeout = 1000;
int HTTPTimeout = 2000;

//Get the IP of the Host
URL url= null;
try {
     url = ResolveHostIP(sURL,DNSTimeout);
} catch (MalformedURLException e) {
    Log.d("INFO",e.getMessage());
}

if(url==null){
    //the DNS lookup timed out or failed.
}

//Build the request parameters
HttpParams params = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(params, HTTPTimeout);
HttpConnectionParams.setSoTimeout(params, HTTPTimeout);

DefaultHttpClient client = new DefaultHttpClient(params);

HttpResponse httpResponse;
String text;
try {
    //Execute the request (here it blocks the execution until finished or a timeout)
    httpResponse = client.execute(new HttpGet(url.toString()));
} catch (IOException e) {
    //If you hit this probably the connection timed out
    Log.d("INFO",e.getMessage());
}

//If you get here everything went OK so check response code, body or whatever

Método utilizado:

//Run the DNS lookup manually to be able to time it out.
public static URL ResolveHostIP (String sURL, int timeout) throws MalformedURLException {
    URL url= new URL(sURL);
    //Resolve the host IP on a new thread
    DNSResolver dnsRes = new DNSResolver(url.getHost());
    Thread t = new Thread(dnsRes);
    t.start();
    //Join the thread for some time
    try {
        t.join(timeout);
    } catch (InterruptedException e) {
        Log.d("DEBUG", "DNS lookup interrupted");
        return null;
    }

    //get the IP of the host
    InetAddress inetAddr = dnsRes.get();
    if(inetAddr==null) {
        Log.d("DEBUG", "DNS timed out.");
        return null;
    }

    //rebuild the URL with the IP and return it
    Log.d("DEBUG", "DNS solved.");
    return new URL(url.getProtocol(),inetAddr.getHostAddress(),url.getPort(),url.getFile());
}   

Esta clase es de esta entrada de blog. Vaya y compruebe los comentarios si va a usarlo.

public static class DNSResolver implements Runnable {
    private String domain;
    private InetAddress inetAddr;

    public DNSResolver(String domain) {
        this.domain = domain;
    }

    public void run() {
        try {
            InetAddress addr = InetAddress.getByName(domain);
            set(addr);
        } catch (UnknownHostException e) {
        }
    }

    public synchronized void set(InetAddress inetAddr) {
        this.inetAddr = inetAddr;
    }
    public synchronized InetAddress get() {
        return inetAddr;
    }

Puede crear una instancia HttpClient por cierto con Httpclient-android-4.3.5,puede funcionar bien.

 SSLContext sslContext = SSLContexts.createSystemDefault();
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslContext,
                SSLConnectionSocketFactory.STRICT_HOSTNAME_VERIFIER);
                RequestConfig.Builder requestConfigBuilder = RequestConfig.custom().setCircularRedirectsAllowed(false).setConnectionRequestTimeout(30*1000).setConnectTimeout(30 * 1000).setMaxRedirects(10).setSocketTimeout(60 * 1000);
        CloseableHttpClient hc = HttpClients.custom().setSSLSocketFactory(sslsf).setDefaultRequestConfig(requestConfigBuilder.build()).build();

Una opción es usar el cliente OkHttp, desde Square.

Agregar la dependencia de la biblioteca

En la compilación.gradle, incluye esta línea:

compile 'com.squareup.okhttp:okhttp:x.x.x'

Donde x.x.x es la versión deseada de la biblioteca.

Establecer el cliente

Por ejemplo, si desea establecer un tiempo de espera de 60 segundos, haga lo siguiente:

final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);

Pd: Si tu minSdkVersion es mayor que 8, puedes usar TimeUnit.MINUTES. Por lo tanto, simplemente puede usar:

okHttpClient.setReadTimeout(1, TimeUnit.MINUTES);
okHttpClient.setConnectTimeout(1, TimeUnit.MINUTES);

Para más detalles sobre las unidades, ver TimeUnit.

Si está utilizando el HttpURLConnection, llame a setConnectTimeout() como se describe aquí :

URL url = new URL(myurl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(CONNECT_TIMEOUT);
