Sencha Touch: Using proxy and POST request and URL generation - sencha-touch-2

Question

I have been trying to do a post request using a proxy. I have tried the direct proxy, rest and ajax proxy, and haven't been able to find a working example for a POST request.
Is it possible? Because all the examples that I have seen seen to be using only GET.
Any working examples, or pointers in this direction?
Also, I couldn't figure what is the correct way to generate URLs for a proxy at run-time, for example, calling a function to return the URL.

Answer 1

It appears that this might not be possible:

Answer 2

If you look at the source code for Ext.data.proxy.Rest you'll see a config object for actionMethods. They're not documented, but you should be able to pass that as a config on your proxy to override it.
For example:
proxy: {
type: 'ajax',
url: 'path/to/foo',
actionMethods: {
create : 'POST',
read : 'POST',
update : 'PUT',
destroy: 'DELETE'
},
reader: {
type: 'json',
rootProperty: 'root',
totalProperty : 'totalCount'
}
}

Easiest example of POST request could be like this:
var obj = new Object();
obj.userId = username;
obj.password = password;
var data = Ext.JSON.encode(obj);
Ext.Ajax.request({
url : 'http://myservice/auth/login?_type=json', // url : this.getUrl(),
method : "POST",
headers: {
'Content-Type': 'application/json'
},
params : data,
useDefaultXhrHeader : false,
withCredentials: true,
success : function(response) {
Ext.Msg.alert("Success", "Welcome "+respObj.user.name);
},
failure : function(response) {
var respObj = Ext.JSON.decode(response.responseText);
Ext.Msg.alert("Error", respObj.status.statusMessage);
}
});
Please note here you can customize url as per your convenience.
