SOAPMessage - SOAPConnection - gzip - 如何

Question

我需要在发送SOAP请求和从WebService接收响应时使用压缩。不幸的是，我没有找到任何关于如何启用GZIP压缩的参考。这是我用来发送soap请求的简单代码：

SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();

SOAPConnection sc = scf.createConnection();

MessageFactory mf = MessageFactory.newInstance();

SOAPMessage message = mf.createMessage();

/*
.... some code
*/

URL url = new URL("https://blahblah/service/ws/Someservice");

SOAPMessage reply = sc.call(message, url);

有没有办法在API级别启用压缩，还是我必须自己包装SOAPMessage来实现压缩？

Answer 1

SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();

SOAPConnection sc = scf.createConnection();

MessageFactory mf = MessageFactory.newInstance();

SOAPMessage message = mf.createMessage();

//************** HERE YOU DO THE GZIP********************************

MimeHeaders hd = message .getMimeHeaders();
hd.addHeader("Accept-Encoding", "gzip,deflate,sdch");

/*
.... some code
*/

URL url = new URL("https://blahblah/service/ws/Someservice");

SOAPMessage reply = sc.call(message, url);
