OPTIONS (url) 405 (Method Not Allowed)

[hengboyz]

Sorry if i ask a strange question as i am still new to Sencha Touch.I am facing a problem of the request method of Ajax Proxy in store always OPTIONS which cannot access my web service method, as the web service method is set to GET.Here is my code:

[WebInvoke(Method="GET", UriTemplate="GetCoupons",ResponseFormat=WebMessageFormat.Xml)]
       public List GetCoupons()        {
           List rs = db.MMCO_sp_GetCoupons(null, null, 1).ToList();
           foreach (MMCO_sp_GetCouponsResult temp in rs) 
           { 
               couponList.Add(new Coupon(temp.coupon_code);
           }
           return couponList;
       }

Code in sencha:

Ext.define("Next2Me.store.Coupons", {
    extend: "Ext.data.Store",
        config: {
        model: "Next2Me.model.Coupon",
        autoLoad: true,
        root: {
            expanded: true
        },
        proxy: {
           type: 'ajax', 
           url: 'http://localhost:11827/CouponJSON.svc/web/GetCoupons',
           reader: {
               type: 'xml' 
           }
       }
    }
})

Error:

You are trying to use ajax cross-origin which doesn't work. You can try using CORS (not currently supported within ST2) and this is the reason you are seeing the OPTIONS request. The browser first sends this request to see if the server supports CORS in order to allow the ajax fire cross-origin.

Thanks. So what should be the solution since cors not supported st2. Any suggestion ?

[mitchellsimoens]

JsonP is the only other route but requires you to return JSON within a callback function.

Thanks a lot, buddy.

I solved my problem with JsonP.

So how do I do authorization when ST2 doesn't support CORS and I can't do POST requests with JSONP to send login/pass?

You can run a server-side script which acts as a proxy for all calls.
