Call external web service using jquery

Question

I am using the following code to call external web service using jquery. In Chrome, I am getting this '500 Internal Server Error' and in firefox, it shows '0'

I am unable to figure out the problem. Here is my complete code..

 <script type="text/javascript" src="js/jquery-1.3.1.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jQuery/1.2.6/jQuery.min.js">   
</script>
<script type="text/javascript">
    $(document).ready(function () {
        $("#btnCall").click(function (event) {
            $.ajax({
                type: "POST",
                url: "www.google.com",
                data: "{'ESS123', 'aaaaaa', '', '[email protected]', '23424234', '', 0, 100, 1000007, 1, '', 12, '','','', '2013', '', 1, 1000006, 1000033, 100, 1000012, 1000012, 1000001, 1000001, 100, 'caff4eb4fbd6273e37e8a325e19f0991'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (msg) {
                    alert('s');
                },
                error: AjaxFailed
            });
        });
    });
    function AjaxSucceeded(result) {
        alert('s');
        //alert(result.d);
    }
    function AjaxFailed(result) {
        alert(result.status + ' ' + result.statusText);
    }  
</script>

<body>
 <input type="button" value="Submit" id="btnCall" />
</body>

There could be additional reasons, but your data argument does not contain valid JSON. Invalid input is a common reason for 500 Internal Server Errors.

See JSONLint:

Parse error on line 1:
{    'ESS123',    'aaaaa
-----^
Expecting 'STRING', '}'

(Hint, strings in JSON must be quoted with " characters, and, unlike arrays, objects require key:value pairs not a list of values).

Thanks for your quick response.. Is this the way to do this.. data: {CompanyName: "ESS123", name: "Akhtar", title: "",

No. Keys in JSON objects must be strings. (And I've no idea what data the web service is expecting for input)

Btw server should answer with 400 Bad request in case of bad input better ^^

Quentin Over a year ago

@moonwave99 — I think that is when the request does not conform to the HTTP spec. You can have invalid JSON in the body without violating HTTP. Either way, what a server should do isn't all that relevant to the problem when you're working on the client side!
