WebService通过HTTP协议完成远程调用: (深入分析) – RPC

WebService只采用HTTP POST方式传输数据，不使用GET方式; -- 握手，WSDL-get,

?普通http post的contentType为

?application/x-www-form-urlencoded

?WebService的contentType为－即在Http的基础上发SOAP协议

?text/xml 这是基于soap1.1协议。

?application/soap+xml 这是基于soap1.2协议。

WebService从数据传输格式上作了限定。WebService所使用的数据均是基于XML格式的。目前标准的WebService在数据格式上主要采用SOAP协议。SOAP协议实际上就是一种基于XML编码规范的文本协议。

SOAP – Simple Object Access protocol 简单对像访问协议。是运行在HTTP协议基础之上的协议。其实就是在HTTP协议是传输XML文件，就变成了SOAP协议。目前SOAP的版本主要有SOAP1.1和SOAP1.2。

SOAP1.1和SOAP1.2的namespace不一样。

Soap1.1命名空间：

xmlns:soap=“http://schemas.xmlsoap.org/soap/envelope/“

Soap1.2 命名空间：

xmlns:soap="http://www.w3.org/2003/05/soap-envelope“

可以通过查看类

?javax.xml.ws.soap.SOAPBinding来查看里面的常量

?默认情况下，Jdk1.6只支持soap1.1

?即：@BindingType(value=http://www.mamicode.com/javax.xml.ws.soap.SOAPBinding.SOAP11HTTP_BINDING)

jdk1.6默认不支持12形式的访问。SOAP提升：

通过BindingType将项目转到1.2

在类上面添加以下注解可以使用soap1.2的协议：

?@BindingType(value=http://www.mamicode.com/SOAPBinding.SOAP12HTTP_BINDING)

或在applicationContext.xml中使用binding

?<</SPAN>jaxws:binding>

? <</FONT>soap:soapBindingversion="1.2" />

? </</FONT>jaxws:binding>

3.SOAP1.1版本与SOAP1.2版本在头信息上存在差异。

1.SOAP1.1存在SOAPAction的请求头。

2.SOAP1.2没有SOAPAction的请求头。

4.SOAP1.1和1.2的WSDL文件的差别：

1.主要看命名空间。

2.在定义Service部分差别如下：

Soap1.1是以：soap:address定义。

Soap1.2是以: soap12:address定义。-jdk1.6不支持12形式的访问。

5.在CXF中两种协议请求的方式也不一样。

1.SOAP1.1为content-Type:text/xm;charset=UTF-8

2.SOAP1.2为content-Type:application/soap+xml;charset=UTF-8

SOAP1.1的HTTP请求头：

POST /xe_cxf2.4_soap12_spring_web/ws/helloworldsoap12?wsdl HTTP/1.1
Content-Type: text/xml; charset=UTF-8
Accept: **
User-Agent: Apache CXF 2.4.0
Cache-Control: no-cache
Pragma: no-cache
Host: localhost:6767
Connection: keep-alive
Content-Length: 214

SOAP1.2的请求头：

POST /xe_cxf2.4_soap12_spring_web/ws/helloworldsoap12?wsdl HTTP/1.1
Content-Type: application/soap+xml;charset=UTF-8
Accept: */*
User-Agent: Apache CXF 2.4.0
Cache-Control: no-cache
Pragma: no-cache
Host: localhost:6767
Connection: keep-alive
Content-Length: 214

SOAP1.1 request and SOAP1.2 request:

SOAP 1.1 Request：

POST /WSShakespeare.asmx HTTP/1.1Host: www.xmlme.com Content-Type: text/xml; charset=utf-8Content-Length: length SOAPAction: "http://xmlme.com/WebServices/GetSpeech" <?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>     <GetSpeech xmlns="http://xmlme.com/WebServices">       <Request>string</Request>     </GetSpeech>   </soap:Body> </soap:Envelope>

SOAP1.2 Request:

POST /WSShakespeare.asmx HTTP/1.1Host: www.xmlme.com Content-Type: application/soap+xml; charset=utf-8Content-Length: length  <?xml version="1.0" encoding="utf-8"?> <soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:xsd="http://www.w3.org/2001/XMLSchema"  xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">   <soap12:Body>     <GetSpeech xmlns="http://xmlme.com/WebServices">       <Request>string</Request>     </GetSpeech>   </soap12:Body> </soap12:Envelope>

Differences between SOAP1.1 and  SOAP1.2:

• SOAP 1.2 uses “application/soap+xml” as Content-Type and SOAP 1.1 uses “text/xml”.
• SOAP 1.2 does not use SOAPAction header line.
• SOAP 1.2 uses “http://www.w3.org/2003/05/soap-envelope” as the envolope namespace and SOAP 1.1 uses “http://schemas.xmlsoap.org/soap/envelope/”
