SOAP1.1或SOAP1.2

Question

我有两个由gSOAP库生成的请求消息：

1

POST http://localhost:8998/Service1.svc/ HTTP/1.1
Host: localhost:8998
User-Agent: gSOAP/2.8
Content-Type: application/soap+xml; charset=utf-8; action="http://tempuri.org/IService1/GetData"
Content-Length: 536
Connection: close
SOAPAction: "http://tempuri.org/IService1/GetData"

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns4="http://schemas.datacontract.org/2004/07/WcfService2" xmlns:ns3="http://schemas.microsoft.com/2003/10/Serialization/" xmlns:ns1="http://tempuri.org/"><SOAP-ENV:Body><ns1:GetData><ns1:value>55</ns1:value></ns1:GetData></SOAP-ENV:Body></SOAP-ENV:Envelope>

2

POST http://localhost:8998/Service1.svc/ HTTP/1.1
Host: localhost:8998
User-Agent: gSOAP/2.8
Content-Type: text/xml; charset=utf-8
Content-Length: 538
Connection: close
SOAPAction: "http://tempuri.org/IService1/GetData"

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns4="http://schemas.datacontract.org/2004/07/WcfService2" xmlns:ns3="http://schemas.microsoft.com/2003/10/Serialization/" xmlns:ns1="http://tempuri.org/"><SOAP-ENV:Body><ns1:GetData><ns1:value>55</ns1:value></ns1:GetData></SOAP-ENV:Body></SOAP-ENV:Envelope>

它们是SOAP 1.1还是SOAP 1.2？

第一条消息由代理类形成，默认情况下由wsdl2h和soapcpp2生成。此消息请求失败。第二条消息是由代理生成的，其中包含更改的名称空间：

从…

{"SOAP-ENV", "http://www.w3.org/2003/05/soap-envelope", "http://schemas.xmlsoap.org/soap/envelope/", NULL},

至

{"SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/","http://schemas.xmlsoap.org/soap/envelope/",NULL},

而且效果很好。为什么我需要更改名称空间才能使它工作呢？为什么gSOAP工具不能生成正确的命名空间？

Answer 1

This helpful SO post声明SOAP1.1使用此命名空间：

http://schemas.xmlsoap.org/soap/envelope/

SOAP 1.2使用此命名空间：

http://www.w3.org/2003/05/soap-envelope

因此，第一条消息似乎来自SOAP1.2，而第二条消息似乎来自SOAP1.1。由于您的第一条消息失败了，而第二条消息又通过了，所以您似乎正在使用符合SOAP1.1的服务。

Answer 2

很多时候，您可以知道SOAP请求的版本是1.2，当您看到

Content-Type: application/soap+xml; charset=utf-8; action="address"

SOAP1.1使用Content-Type: text/xml; charset=utf-8
