iOS SOAP 交互

测试服务器

http://www.nanonull.com/TimeService/TimeService.asmx

要传输的xml内容soapXML.xml，不带参数的情况：

<?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>
        <getServerTime xmlns="http://www.Nanonull.com/TimeService/" />
    </soap:Body>
</soap:Envelope>

注意，此xml中不能有注释，如果有注释可能得不到正确的响应

带参数的情况 ，soapXML2.xml

 <?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>
 <getOffesetUTCTime xmlns="http://www.Nanonull.com/TimeService/">
 <hoursOffset>2.1</hoursOffset>
 </getOffesetUTCTime>
 </soap:Body>
 </soap:Envelope>
