MobileServiceClient调用Api超时

Question

我正在使用Android Azure移动服务SDK连接到Azure移动服务。当我使用MobileServiceClient的invokeApi时，当Api在60秒内完成时，一切都很好。

然而，当我的这个Api的方法超过1分钟时，"onCompleted"方法中的"exception"显示"Error which processing request"。

我搜索了所有关于Android Azure移动服务SDK和类MobileServiceClient的文档，找不到任何与此有关的设置，大约60秒的超时设置供我配置。

有人能解释一下吗？

非常感谢。

实现您的自定义OkHttpClientFactory。例如：

public class MyOkHttpClientFactory implements OkHttpClientFactory {
    @Override
    public OkHttpClient createOkHttpClient() {
        long timeout = 30_000;
        TimeUnit unit = TimeUnit.MILLISECONDS;
        OkHttpClient okClient = new OkHttpClient();
        okClient.setConnectTimeout(timeout, unit);
        okClient.setReadTimeout(timeout, unit);
        okClient.setWriteTimeout(timeout, unit);
        return okClient;
    }
}

并将此类的实例设置为MobileServiceClient

MobileServiceClient mobileServiceClient = new MobileServiceClient(SERVICE_URL, Context);
mobileServiceClient.setAndroidHttpClientFactory(new MyOkHttpClientFactory());

这对我有用

OkHttpClient的默认超时值为10秒。

    By default azure is using AndroidHttpClient. This has a default socket operation timeout 1 min(SOCKET_OPERATION_TIMEOUT = 60 * 1000)

我们可以简单地将其编辑为

 HttpConnectionParams.setConnectionTimeout(client.getParams(), SOCKET_OPERATION_TIMEOUT);
        HttpConnectionParams.setSoTimeout(client.getParams(), SOCKET_OPERATION_TIMEOUT);
    Inside azure sdk there is an interface ServiceFilterRequest and it holds a method 
     public ServiceFilterResponse execute() throws Exception;
    We can edit this method and add our custom interval as follows.
    1. Open its implementation class ServiceFilterRequestImpl.
    2. set a connection interval time 
        // I'm changing the default 1 min to 5 minutes..
        private static final int SOCKET_OPERATION_TIMEOUT = 5 * 60 * 1000;
    3. edit  public ServiceFilterResponse execute() throws Exception { } method
      public ServiceFilterResponse execute() throws Exception {
            // Execute request
            AndroidHttpClient client = mAndroidHttpClientFactory.createAndroidHttpClient();
            client.getParams().setParameter(HTTP.USER_AGENT, MobileServiceConnection.getUserAgent());

 //Overriding the default interval with the desired connection timeout value.
            HttpConnectionParams.setConnectionTimeout(client.getParams(), SOCKET_OPERATION_TIMEOUT);
            HttpConnectionParams.setSoTimeout(client.getParams(), SOCKET_OPERATION_TIMEOUT);

            try {
                final HttpResponse response = client.execute(mRequest);
                ServiceFilterResponse serviceFilterResponse = new ServiceFilterResponseImpl(response);
                return serviceFilterResponse;
            } finally {
                client.close();
            }
        }

这将解决问题。

经过长期研究，Azure Mobile Service for Android使用MobileServiceClient类，并使用AndroidHttpClient与我们的Azure Mobile Services url进行SSL通信。而AndroidHttpClient，从这个后android httpclient挂起第二个到服务器的请求（连接超时），有一个默认的"合理"设置，即SSL访问超时60秒！OMG.

不知道Azure Mobile Service for Android团队中的人是否能看到这篇文章，并为我们找到一种方法，使超时设置直接在Azure Mobile Service of Android类中进行配置。
