Java使用SOAP获取webservice实例解析

1.webservice提供方：http://www.webxml.com.cn/zh_cn/index.aspx
2.下面我们以“获得腾讯QQ在线状态”为例。
参数截图如下图：

SOAP 1.1

以下是 SOAP 1.2 请求和响应示例。所显示的占位符需替换为实际值。

 4、SendInstantSms.xml文件如下，放在src目录下

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <qqCheckOnline xmlns="http://WebXml.com.cn/">
      <qqCode>qqCodeTmp</qqCode>
    </qqCheckOnline>
  </soap:Body>
</soap:Envelope>
