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

您需要构造一个请求XML负载，如下所示

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

并设置有效负载和标头，以便调用端点

    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);
