该博客展示了一个使用SOAP请求Web服务的示例。定义了文件操作常量、调用URL和方法名，构建了SOAP请求的XML内容，通过Microsoft.XMLHTTP对象发送请求，并将应答记录到文件中，涉及XML、SOAP等信息技术知识。

在使用之前，我们需要了解SOAP的数据包格式，以及数据包返回的格式，通过查看asmx文件，我们知道了他们的格式：

POST /WEBSERVICES/school.asmx HTTP/1.1
Host: www.chefbj.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.chefbj.com/show_school"

<?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>
    <show_school xmlns="http://www.chefbj.com">
      <password>string</password>
    </show_school>
  </soap:Body>
</soap:Envelope>

HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?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>
    <show_schoolResponse xmlns="http://www.chefbj.com">
      <show_schoolResult>
        <xsd:schema>schema</xsd:schema>xml</show_schoolResult>
    </show_schoolResponse>
  </soap:Body>
</soap:Envelope>

下面就可以使用SOAP方式来获取数据
