I'm confused about GET and POST in Sencha-touch

**pcr** · 14 Jan 2011, 3:20 AM

I have a lot of PHP serverscripts that produce JSON from a DB to fill a store. These scripts looks for POST and GET parameters. If a POST parameter is available the script send normal JSON. If only GET parameter is received the script sends callback(.....) javascript. Because in ExtJS HttpProxy is default send with type: 'POST' and HttpScriptTagProxy requests are send with default type: 'GET'.

I expected Sencha-touch behave like ExtJS. No matter what I try to make request to get storedata Sencha-touch always send a GET request with URL-params. Another issue is that Sencha-touch expects a JSON message back and not a callback javascript.

As a workaround I sent an extra param mobile: true in requests. My PHP scripts now looks for this ??GET param mobile and act like a request width send with POST and send back a JSON message.

Is it possible to make requests that use type: POST???

Hi, sure you can make POST requests.
Try to write your request like this:

PHP Code:


Ext.Ajax.request({
    url: 'your_url'
    method: 'post',
    params: {
        my_param: 'my_value'
    },
    success: function(response, opts) {
                    
           //Do what you want
     }
})

Hope this helps.

Hi Andrea,

I know. I used that always in ExtJS. Works perfect. But if you try to define a proxy like following code, Sencha-touch ignores the parameter and always sends a GET Request with values added in the URL.

Code:

	var servincidentStore = new Ext.data.Store({
		model: 'Incident',
		storeId: 'incident',
		proxy: {
			type: 'ajax',
			url: '/generator-grid/BackendGrid/incidentGridBackend.php',
			method: 'POST',
			extraParams: {
				mobile: true,
				start: 0,
				limit: 9999,
				userProfielId: profielid,
				task: 'LISTING',
				xvelden: ', incident.PersoonId ',
				sort: 'incident.Incident',
				dir: 'ASC'
			},
			reader: {
				type: 'json',
				root: 'results'
			}
		}
	});

Here is a copy of the request send by code above:

Code:

Verzoek-URL:http://localhost/generator-grid/BackendGrid/incidentGridBackend.php?_dc=1295089977116&mobile=true&start=0&limit=25&userProfielId=791&task=LISTING&xvelden=%2C%20incident.PersoonId%20&sort=incident.Incident&dir=ASC
Verzoekmethode:GET
Statuscode:200 OK

Hi,
Sencha Touch it's a little bit different from Ext.
If you have to get data from a Store using Post, you have to set the actionMethods config as follow instead of method.

PHP Code:


var servincidentStore = new Ext.data.Store({

    model: 'Incident',

    storeId: 'incident',

    proxy: {

        type: 'ajax',

        url: '/generator-grid/BackendGrid/incidentGridBackend.php',

        actionMethods: {

         read: 'POST'

        },

        extraParams: {

            mobile: true,

            start: 0,

            limit: 9999,

            userProfielId: profielid,

            task: 'LISTING',

            xvelden: ', incident.PersoonId ',

            sort: 'incident.Incident',

            dir: 'ASC'

       },

       reader: {

          type: 'json',

          root: 'results'

       }

    }

});

Hope this helps.

We're trying the same way but getting the following error, Stuck in this

, using Sencha touch

If you call this using Chrome's REST Console plugin it returns correct response, but May be in case of POST request from STORE it adds some header?

Can anybody please help here...

Following is the code

-----------------------CODE-----------------

var ProductListStore = new Ext.data.Store({
model: 'ProductListRoot',
proxy: {
type: 'ajax',
actionMethods: {
read: 'POST'
},
url: urlIdentifier + instanceId + implementationId + productListSearchURL,
reader:{
type: 'json',
root: 'contents'
}

},
autoLoad:true
});
---------------------------------------------------

and Following is the error

Following is the error return if we inspect in the browser's console.

----------------------------------ERROR---------------------------
