Android的HttpURLConnection在HEAD请求上抛出EOFException。

http android java httpurlconnection urlconnection

这个小代码片段在我的Mac的JVM上运行良好。不幸的是，它在Android 4.2上执行时会崩溃。

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() + "" );
    }
}

如果我用它替换它，工作正常，但我无法弄清楚原因。https://github.comhttps://www.facebook.com

异常不包含消息;所以这里至少是堆栈跟踪。

事实证明，这是Android类实现中的一个已知错误。连接前呼叫可用作解决方法。Connection.setRequestProperty( "Accept-Encoding", "" );
