jQuery Ajax SOAP没有响应

Question

I do not know what exactly happening with me. I am trying to call soap service but im not getting any response.

function soap_call(){     
    var wsUrl = "https://ws.cert.transactionexpress.com/portal/merchantframework/MerchantWebServices-v1?wsdl";
    var soapRequest = 
        '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://postilion/realtime/merchantframework/xsd/v1/"> \
          <SOAP-ENV:Body> \

        </SOAP-ENV:Envelope>' ;
        jQuery.ajax({
            type: "POST",
            url: wsUrl,
            contentType: "text/xml; charset=\"utf-8\"",
            dataType: "xml",
            data: soapRequest,
            //processData: false,
            //async:true,
            headers: {
                SOAPAction: "UpdtRecurrProf"
            },
            complete: function (xmlHttpRequest) {
                alert(xmlHttpRequest.responseXML);
            },

        });

    }

I tried to call using this link , then it gave me correct response.

I do not have expertise in soap. I will appreciate if anyone can help me out from here.

Just checked your request with a Postman - there's everything absolutely fine with a request itself. Here's the response I had:

<?xml version='1.0' encoding='UTF-8'?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <ns2:UpdtRecurrProfResponse xmlns="http://postilion/realtime/portal/soa/xsd/Faults/2009/01" xmlns:ns2="http://postilion/realtime/merchantframework/xsd/v1/">
            <ns2:custId>1450956517822188336</ns2:custId>
            <ns2:pmtId>1450956517853193808</ns2:pmtId>
            <ns2:rspCode>00</ns2:rspCode>
        </ns2:UpdtRecurrProfResponse>
    </S:Body>
</S:Envelope>

The problem appears because of you use javascript and same origin policy doesn't allow you to request domains, which are different from yours - this helps to protect from XSS attacks.

It could be possible to request remote host though, if it provides a CORS header, like Access-Control-Allow-Origin: *, which allows all domains to request it, but looking at the response, it does not return this header it this case:

Cache-Control → private
Content-Encoding → gzip
Content-Type → text/xml;charset=utf-8
Date → Thu, 24 Dec 2015 11:28:37 GMT
Server → WebServer
Transfer-Encoding → chunked

Also you should see this error message in your browser console, which approves my suggestion.

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource

So the problem is not with SOAP request itself, but with that you try to request it via javascript. Make a request through on your backend (PHP for instance) - and it should go smoothly.
