Question

i’m a beginner in Classic ASP and this is my first question in stackoverflow… i need to transform a query string, with a random number of parameters in json:

param1=hi&param2=hello&param3=byebye....  paramN=gudnight

in something like this:

{"param1":"hi","param2":"hello","param3":"byebye"...,"paramN":"gudnight"}

is there something to do this automatically in asp??

Here you go.

<script language="javascript" runat="server" src="http://www.JSON.org/json2.js"></script>

<%
    DIM jsonQueryString
    SET jsonQueryString = JSON.parse("{}")

    For Each item In Request.QueryString
        DIM key : key = Request.QueryString.Key(item)
        DIM val : val = Request.QueryString(key)(1)
        jsonQueryString.set key, val
    Next

    Response.Write JSON.stringify(jsonQueryString)
%>

UPDATE: The json2.js file included is a json parser class but it is no longer at that location. We downloaded a copy of it which is on our servers and we currently use. You can find an up to date copy of it at the following url – https://github.com/douglascrockford/JSON-js.

So if I hit my test page with the following url –

http://localhost:8080/tests/ws/parsequerytojson.asp?a=1&b=2&c=3

I get the following JSON formatted response –

{
    a: "1",
    b: "2",
    c: "3"
}
