我使用的是Android的查询，使HTTP调用，我不断收到随机SSLExceptions，像这样的：

I'm using Android-Query to make HTTP calls, and I keep getting random SSLExceptions, like these:

目前似乎没有无缘无故就其发生。他们可能发生的时间1/6我拨打任何电话。

There seems to be no rhyme or reason as to their occurrence. They happen maybe 1/6 of the time I make any calls.

下面是我如何使用Android的查询（ $ ）：

Here is how I'm using Android-Query ($):

//应用程序中创建：

// APPLICATION CREATE:

public void onCreate()
{
  AQUtility.setExceptionHandler( new UncaughtExceptionHandler() {
    public void uncaughtException( Thread thread, Throwable ex )
    {
      ex.printStackTrace();
    }
  } );

  AQUtility.setDebug( true );

  AjaxCallback.setTransformer( new JsonTransformer() );

  //set the max number of concurrent network connections, default is 4
  AjaxCallback.setNetworkLimit( 8 );

  //set the max number of icons (image width <= 50) to be cached in memory, default is 20
  BitmapAjaxCallback.setIconCacheLimit( 20 );

  //set the max number of images (image width > 50) to be cached in memory, default is 20
  BitmapAjaxCallback.setCacheLimit( 40 );

  //set the max size of an image to be cached in memory, default is 1600 pixels (ie. 400x400)
  BitmapAjaxCallback.setPixelLimit( 480 * 480 );

  //set the max size of the memory cache, default is 1M pixels (4MB) (2---)
  BitmapAjaxCallback.setMaxPixelLimit( 4000000 );

  super.onCreate();
}

//用法 //注意：URI = // 07-13 17：26：08.040：W / AQuery（7746）：得到如下：https：//site.com/me/ticker/

// USAGE // NOTE: uri = // 07-13 17:26:08.040: W/AQuery(7746): get:https://site.com/me/ticker/

$.auth( Security.getAuth( this ) ).ajax( uri, BaseModelListRequest.class, this, "loadAdapterObjectsCallback" );

public void loadAdapterObjectsCallback( String uri, BaseModelListRequest requestData, AjaxStatus status )
{
  setProgressBarIndeterminateVisibility( false );
  setSupportProgressBarIndeterminateVisibility( false );

  if( requestData != null && status.getCode() == 200 )
  {
     // stuff 
  }
}

//这里是GETAUTH：

// HERE IS GETAUTH:

public static synchronized BasicHandle getAuth( Context context )
{
  return new BasicHandle( "user", "pass" );
}

//及JSONTRANSFORMER（使用jaxson马歇尔JSON）：

// AND THE JSONTRANSFORMER (uses jaxson to marshall json):

public class JsonTransformer implements Transformer
{
  public < T > T transform( String url, Class< T > type, String encoding, byte[] data, AjaxStatus status )
  {
    ObjectMapper mapper = new ObjectMapper();

    try
    {
      return mapper.readValue( new String( data ), type );
    }
    catch( Exception e )
    {
      return null;
    }
  }
}

编辑：这发生在2.X和3.X，使用SSL。禁用SSL（HTTPS - > HTTP），使得它的工作

This happens on 2.X and 3.X, using SSL. Disabling SSL (https -> http) makes it work.

下面是另一个例外，SSL：

Here is another exception, with SSL:

编辑2：

进一步检查产量。卸下S的协议（即SSL）使一切工作正常。

Further inspection yields that the error occurs on Android 2.3.x devices. Removing the "s" in the protocol (ie SSL) makes everything work fine.

我已经previously有这个问题，RestTemplate（弹簧的Andr​​oid），并按照这一职位的建议固定它：的自我签名SSL接受Android的

I have previously had this issue with RestTemplate (Spring-Android), and fixed it by following this post's recommendations: Self Signed SSL acceptance Android

不过，我修改了源到Android查询以同样的方式，而且它并没有解决这个问题。

However, I modified the source to Android-Query in the same manner, and it did not fix the issue.

推荐答案

这个问题已经被问了几次here和here.此异常似乎是连接被重置由服务器的结果。我不认为有很多，你可以在应用程序code以外的其他正常处理异常和移动做。如果服务器在你的控制这将是值得的检查日志和配置，看看是什么原因造成的连接被重置。您可能能够减少或解决问题，而不是有

This question has been ask a couple of times here and here. This exception seems to be the result of the connection being reset by the server. I don't think there's much you can do in your application code other than to gracefully handle the exception and move on. If the server is under your control it would be worthwhile check the logs and configuration to see what is causing the connection to be reset. You might be able to minimize or resolve the issue there instead.
