WebService使用的是 SOAP (Simple Object Access Protocol)协议 Soap协议只是用来封装消息用的。封装后的消息你可以通过各种已有的协议来传输比如http,tcp/ip,smtp,等等你甚至还一次用自定义的协议当然也可以用https协议。 Soap建立在http上说白了是用http传送xml而已。
SOAP协议 HTTP协议 XML数据格式SOAP协议是基于HTTP协议的两者的关系就好比高速公路是基于普通公路改造的在一条公路上加上隔离栏后就成了高速公路。 WebService采用HTTP协议传输数据采用XML格式封装数据即XML中说明调用远程服务对象的哪个方法传递的参数是什么以及服务对象的返回结果是什么。WebService通过HTTP协议发送请求和接收结果时发送的请求内容和结果内容都采用XML格式封装并增加了一些特定的HTTP消息头以说明HTTP消息的内容格式这些特定的HTTP消息头和XML内容格式就是SOAP协议(simple object access protocol,简单对象访问协议) 。 商店的服务员只要收到了钱就给客户提供货物商店服务员不用关心客户是什么性质的人客户也不用关心商店服务员是什么性质的人。同样WebService客户端只要能使用HTTP协议把遵循某种格式的XML请求数据发送给WebService服务器WebService服务器再通过HTTP协议返回遵循某种格式的XML结果数据就可以了WebService客户端与服务器端不用关心对方使用的是什么编程语言。
原生底层webService的调用方式
1、在服务器上通过 curl 地址 命令来获取xml文件格式。
2、获取到格式后在服务器上通过curl的完整命令进行测试返参等。
curl --location --request POST 地址 \
--header Content-Type: text/xml \
--data soapenv:Envelope xmlns:xsihttp://www.w3.org/2001/XMLSchema-instance xmlns:xsdhttp://www.w3.org/2001/XMLSchema xmlns:soapenvhttp://schemas.xmlsoap.org/soap/envelope/ xmlns:hjbhttp://localhost:8080/hjbjWebServicesoapenv:Header/soapenv:Bodyxxx:xxxxxx soapenv:encodingStylehttp://schemas.xmlsoap.org/soap/encoding/in0 xsi:typexsd:string入参/in0/xxx:xxxxxx/soapenv:Body
/soapenv:Envelope3、解析xml访问三方服务
