Java Android查询-随机SSLExceptions

我正在使用Android Query进行HTTP调用，并且我不断得到随机的SSLexception，比如：

AQuery(7746): javax.net.ssl.SSLException: Read error: ssl=0x19d3c0: I/O error during system call, Connection reset by peer

AQuery(7746):   at java.lang.Thread.run(Thread.java:1020)

关于它们的发生似乎没有任何韵律或理由。我打电话的时间大概有六分之一会发生这种情况

下面是我如何使用Android查询（

$

）：

//应用程序创建：

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();
}

//下面是GETAUTH：

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

//JSONTRANSFORMER（使用jaxson来处理json）：

编辑2:

进一步检查表明，错误发生在Android 2.3.x设备上。删除协议中的“s”（即SSL）可以使一切正常工作

我以前在RestTemplate（Spring Android）上遇到过这个问题，并按照本文的建议解决了这个问题：

---

然而，我以同样的方式将源代码修改为Android查询，但它并没有解决这个问题。

这个问题已经被问了好几次了。此异常似乎是服务器重置连接的结果。我认为除了优雅地处理异常并继续前进之外，在应用程序代码中没有什么可以做的。如果服务器在您的控制之下，则值得检查日志和配置，以查看是什么导致连接被重置。您可以在那里最小化或解决问题。

可能重复的

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

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;
    }
  }
}
