如何使用 Ballerina 调用 SOAP-XML WS

Question

我正在尝试使用 Ballerina 和 http:ClientConnector 调用 SOAP WS，如何将 Body 和参数传递给 POST 方法？

Answer 1

请参考sample code of soapConnector.bal（0.93版）

你需要像这样构造一个请求 XML 负载

xml soapRequest = xmls:parse("<soapenv:Envelope xmlns:soapenv=\"" + namespace + "\"></soapenv:Envelope>");

并设置有效负载以及标头以调用端点

    message backendServiceReq ={};
    string reqType = "application/soap+xml";
    string soapDefinition;
    soapDefinition, _ = (string) namespaceMap["1.2"];
    messages:setXmlPayload(backendServiceReq, soapRequest);
    messages:setHeader(backendServiceReq, "Content-Type", reqType);
    if (soapAction != "null") {
        messages:setHeader(backendServiceReq, "SOAPAction", soapAction);
    } 
   message response = httpConnector.post(url, backendServiceReq);
