/**
 * SOAP客户端
 *
 * 

此对象用于构建一个SOAP消息,并通过HTTP接口发出消息内容。 SOAP消息本质上是一个XML文本,可以通过调用{@link #getMsgStr(boolean)} 方法获取消息体 * *

使用方法: * *

 * SoapClient client = SoapClient.create(url)
 * .setMethod(methodName, namespaceURI)
 * .setCharset(CharsetUtil.CHARSET_GBK)
 * .setParam(param1, "XXX");
 *
 * String response = client.send(true);
 *
