这个小代码片段可以在Mac的JVM上正常运行。不幸的是,它在Android 4.2上执行时崩溃。
import java.net.HttpURLConnection;
import java.net.URL;
public class App
{
public static void main( String... arguments ) throws Exception
{
HttpURLConnection connection = (HttpURLConnection) new URL( "https://github.com" ).openConnection();
connection.setRequestMethod( "HEAD" );
System.out.println( connection.getResponseCode() + "" );
}
}
如果我将https://github.com
替换为https://www.facebook.com
,它可以正常工作,但我无法找出原因。
该异常不包含消息;所以这里至少是堆栈跟踪。
java.io.EOFException

答案 0 :(得分:40)
原来这是Android类实现中的已知错误。在连接之前调用Connection.setRequestProperty( "Accept-Encoding", "" );
可以用作解决方法。
