Question

I have a script file that makes a call to JSON API, and I need to send the current login username as part of the call. I tried the following :-

    $(document).ready(function () {
        var name = prompt("Please enter your packageid", "test");

        var fullurl = 'http://localhost:8080/jw/web/json/workflow/process/list?j_username=kermit&hash=9449B5ABCFA9AFDA36B801351ED3DF66&loginAs=' + HttpContext.Current.User.Identity.Name + 'packageId=' + name;
        $.ajax({
            type: "GET",
            url: fullurl,
            dataType: "JSONP",
            success: function (result) {
//code goes here

But it will raise the following error:- ‘HttpContext’ is undefined

Answer 1

Your script is looking for a Javascript variable called HttpContext Your code should be

@HttpContext.Current.User.Identity.Name

in Razor

so the javascript becomes

 var fullurl = 'http://localhost:8080/jw/web/json/workflow/process/list?j_username=kermit&hash=9449B5ABCFA9AFDA36B801351ED3DF66&loginAs=@HttpContext.Current.User.Identity.Name&packageId=' + name;

You’re also missing and & between the user name and packageId if you intended for them to be separate variables

Edit: based on your comment and this being inside of a js file (which I guess I missed in the OP)

Two options:

1. Is to hold the username inside a variable on the page calling the script file. Like this:

Page

<script>
var usrName = "@HttpContext.Current.User.Identity.Name";
</script>

JS file

....&loginAs='+ usrName + '&packageId=' + name;

Option Two is to not include the username at all and just get it from the Action. This is only an option if the page you’re posting to is on the same app
