Java，WebService，SOAP-UI生成SOAP，HTTPClient調用服務

SOAP-UI

SoapUI是為Windows、Mac和Linux作業系統開發的免費程式。作為測試SOAP（簡單對象通路協定）和REST（代表性狀态傳輸）web協定的一種方法，SoapUI提供了執行許多不同測試所需的工具和功能。這些測試包括功能測試、負載測試、安全測試和模拟。作為一個開源程式，SoapUI是市場上第一個同類的API測試工具，并且在開發人員的幫助下已經形成了今天的産品。

生成SOAP

SOAP請求封包：

POST http://192.168.3.50:9199/demo/cxf/userWebService HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: ""
Content-Length: 299
Host: 192.168.3.50:9199
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.5 (Java/17.0.2)

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://service.demo.com">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:userInfo>
         <!--Optional:-->
         <username>?</username>
      </ser:userInfo>
   </soapenv:Body>
</soapenv:Envelope>           

SOAP響應封包

HTTP/1.1 200 
Content-Type: text/xml;charset=UTF-8
Content-Length: 208
Date: Fri, 11 Mar 2022 11:00:04 GMT
Keep-Alive: timeout=60
Connection: keep-alive

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <ns2:userInfoResponse xmlns:ns2="http://service.demo.com">
            <String>?</String>
        </ns2:userInfoResponse>
    </soap:Body>
</soap:Envelope>
