soap1.1 和 1.2 的区别主要表现在
区别 （1）
http头的 Content-Type: 字段
1.1的 Content-Type: text/xml; charset=utf-8
1.2的 Content-Type: application/soap+xml; charset=utf-8
区别（2）
http头的SOAPAction: 字段
1.1的要求有 SOAPAction: 字段，内容为 明明空间＋方法名
1.2版本 不需要 SOAPAction: 字段
区别（3）
namespace不同
1.1版本的namespace 为 http://www.w3.org/2003/05/soap-envelope
1.2版本的namespace 为 http://schemas.xmlsoap.org/soap/envelope/
SOAP 1.2范例
SOAP 请求：
POST /InStock HTTP/1.1
Host: www.example.org
Content-Type: application/soap+xml; charset=utf-8
Content-Length: nnn
<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
<soap:Body xmlns:m="http://www.example.org/stock">
<m:GetStockPrice>
<m:StockName>IBM</m:StockName>
</m:GetStockPrice>
</soap:Body>
</soap:Envelope>
SOAP 响应：
HTTP/1.1 200 OK Content-Type: application/soap+xml; charset=utf-8 Content-Length: nnn <?xml version="1.0"?> <soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding"> <soap:Body xmlns:m="http://www.example.org/stock"> <m:GetStockPriceResponse> <m:Price>34.5</m:Price> </m:GetStockPriceResponse> </soap:Body> </soap:Envelope>
