ExtJs, how to send JSON on store.load() using POST method

Question

I need to send JSON object during read operation on store. Headers and method are set correctly.

var proxyDefinition = {
    type : 'rest',
    api : {
        read : '/some/url'
    },
    actionMethods : {
        create  : 'POST',
        read    : 'POST',
        update  : 'PUT',
        destroy : 'DELETE'
    },
    reader : {
        type : 'json'
    }        
};

var store = Ext.create('Ext.data.Store', {
    proxy : proxyDefinition,
    model : 'SomeModel'
});

// this needs to send JSON
store.load({
    params : {
        filter: [] // some filtering rules
    }
});

Problem is that POST body is sent as url encoded query string, not JSON object with property "filter".

ExtJs version 4.2.2

Solution

It is likely that you are looking for proxy config option paramsAsJson:true

But what to do, if you want to make POST request and send some params as query params, rest as request payload?
