js调用webservice接口并解决no soap Action Header问题

背景

调用第三方接口，对方接口为内网地址，并且与我方服务器不通，所以需要在js调用对方提供的webservice接口

调用方法

function RequestWebService() {
    var data;
    data = '<soapenv:Envelope xmlns:xsi="http://www.w3.org/XMLSchema-instance" xmlns:xsd="http://www.w3.org/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/envelope/" xmlns:prox="http://proxy.sun.com"><soapenv:Header/><soapenv:Body><prox:acceptMessage soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><in0 xsi:type="xsd:string"><![CDATA[<Request><Header><sender>HIS</sender><receiver>PLAT</receiver><sendTime>20170120173325</sendTime><msgType>TCM_HIS_01</msgType><outpatientNo>320903|18860826500</outpatientNo><orgCode>320903</orgCode></Patient></Request> ]]></in0></prox:acceptMessage></soapenv:Body></soapenv:Envelope>';

    var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    var URL = "http://esb.sinosoft.com.cn/services/HIS?wsdl";
    xmlhttp.Open("POST", URL, false);
    xmlhttp.SetRequestHeader("Content-Type", "text/xml; charset=utf-8"); //SOAP 1.1为text/xml ； 1.2为 application/soap+xml
    xmlhttp.SetRequestHeader("SOAPAction", "http://engine.transfer.com/acceptMessage"); //设置SOAPAction
    xmlhttp.Send(data);

    var text = xmlhttp.responseText;
    console.log(text); //返回结果
}

参数解释：

data为在soap-ui中请求接口的xml文本，直接复制过来就可以；

no soap action header问题解决办法

xmlhttp.SetRequestHeader("SOAPAction", "http://engine.transfer.com/acceptMessage"); //设置SOAPAction
