How to set HttpResponse timeout for Android in Jav

2018-12-31 08:31发布

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!

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);

public boolean isInternetWorking(){
    try {
        int timeOut = 5000;
        Socket socket = new Socket();
        SocketAddress socketAddress = new InetSocketAddress("8.8.8.8",53);
        socket.connect(socketAddress,timeOut);
        socket.close();
        return true;
    } catch (IOException e) {
        //silent
    }
    return false;

An option is to use the OkHttp client, from Square.

Add the library dependency

In the build.gradle, include this line:

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

Where x.x.x is the desired library version.

Set the client

For example, if you want to set a timeout of 60 seconds, do this way:

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

ps: If your minSdkVersion is greater than 8, you can use TimeUnit.MINUTES. So, you can simply use:

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

For more details about the units, see TimeUnit.

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 (e.g. DefaultHttpClient or AndroidHttpClient) you can use the function setParams().

httpClient.setParams(httpParameters);

If you're using the default http client, here's how to do it using the default http params:

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

you can creat HttpClient instance by the way with Httpclient-android-4.3.5,it can work well.

 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();
