how to pass credentials for a webservice using jquery ajax call?

Question

I am using the jquery ajax call like this:

$.ajax({
         url: WEBSERVICE_URL,
            type: "GET",
            dataType: "application/json; charset=utf-8",                   
            username: "admin",  // Most SAP web services require credentials
            password: "admin",
            processData: false,
            contentType: "application/json",
            success: function() {
               alert("success");
            },
            error: function() {
                   alert("ERROR");
                },
    });

still the call is not going to web service. Everytime I am getting ERROR alert. Can some body help me on this please?

Answer 1

If you are doing cross domain request:

$.ajax({
    url: "yoururl",
    type: "GET",
    dataType: 'json',
    xhrFields: {
         withCredentials: true
    }
});

Try using post for the method type, most webservices are secured and require transimssion using post and not Get

plus to help you debug the error and a response text to your error.

 $.ajax({
     url: WEBSERVICE_URL,
     type: "POST", //This is what you should chage
     dataType: "application/json; charset=utf-8",
     username: "admin", // Most SAP web services require credentials
     password: "admin",
     processData: false,
     contentType: "application/json",
     success: function () {
         alert("success");
     },
     error: function (xhr, ajaxOptions, thrownError) { //Add these parameters to display the required response
         alert(xhr.status);
         alert(xhr.responseText);
     },
 });
