从同一服务器上的经典ASP https：//站点调用ASPX Web服务/页面

Question

I've got an ASP app running under SSL that I want to extend by using JQuery/Ajax and thought I'd write the methods that are called by it in .NET, hosted on the same server. How do I set it up? Should it be within the SSL domain?

Answer 1

Here's an example . Decorate the web service with the [ScriptService] attribute and then invoke it:

$.ajax({
    type: 'POST',
    url: '/WebserviceName.asmx/MethodName',
    data: JSON.stringify({
        Parameter1: 'foo', 
        Parameter2: 'bar'
    }),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function(json) { 
        // TODO: do something with the result
    }
});

You could do the same with an ASPX page with PageMethods .

The only requirement is that the client is hosted on the same domain and it doesn't violate the same origin policy . So for example if the .NET page is hosted on HTTPS and your client page on HTTP you cannot send AJAX requests (that's considered as a violation of the same origin policy).
