Extjs4 使用store的post方法

Extjs4 使用store的post方法

 引用官网的一句话

  Now when we call store.load(), the AjaxProxy springs into action, making a request to the url we configured (‘users.json‘ in this case). As we‘re performing a read, it sends a GET request to that url (see actionMethods to customize this - by default any kind of read will be sent as a GET request and any kind of write will be sent as a POST request).

我们点进去看看它源码:

Ext.define(‘Ext.data.proxy.Ajax‘, {    requires: [‘Ext.Ajax‘],    extend: ‘Ext.data.proxy.Server‘,    alias: ‘proxy.ajax‘,    alternateClassName: [‘Ext.data.HttpProxy‘, ‘Ext.data.AjaxProxy‘],        /**     * @property {Object} actionMethods     * Mapping of action name to HTTP request method. In the basic AjaxProxy these are set to ‘GET‘ for ‘read‘ actions     * and ‘POST‘ for ‘create‘, ‘update‘ and ‘destroy‘ actions. The {@link Ext.data.proxy.Rest} maps these to the     * correct RESTful methods.     */    actionMethods: {        create : ‘POST‘,        read   : ‘GET‘,        update : ‘POST‘,        destroy: ‘POST‘    },        // Keep a default copy of the action methods here. Ideally could just null    // out actionMethods and just check if it exists & has a property, otherwise    // fallback to the default. But at the moment it‘s defined as a public property,    // so we need to be able to maintain the ability to modify/access it.     defaultActionMethods: {        create : ‘POST‘,        read   : ‘GET‘,        update : ‘POST‘,        destroy: ‘POST‘        },
  ... ... ...
}

到这里,我想你的思路也很清晰了.具体做法如下


1.覆盖 actionmathods 方法:

Ext.define(‘Sencha.store.Users‘, {    extend: ‘Ext.data.Store‘,    config: {        model: ‘Sencha.model.Users‘,        autoLoad: true,        proxy: {            type: ‘ajax‘,            actionMethods: {                create : ‘POST‘,                read   : ‘POST‘, // by default GET                update : ‘POST‘,                destroy: ‘POST‘            },            url: ‘teams.json‘        }    }});

 

var mystore = Ext.create(‘Ext.data.Store‘, {        // 分页大小        pageSize : 20,        model : ‘mydata‘,        storeId : ‘mystore‘,        proxy : {            type : ‘ajax‘,            actionMethods : {                create : ‘POST‘,                read : ‘POST‘, // by default GET                update : ‘POST‘,                destroy : ‘POST‘            },            url : mj.basePath + ‘service/user!datagrid.cy‘,            reader : {                root : ‘leafData‘,                totalProperty : ‘totalRows‘            }        },        sorters : [ {            property : ‘createTime‘, // 排序字段            direction : ‘desc‘// 默认ASC        } ]    })

2. 覆盖 defaultActionMethods 方法:

var mystore = Ext.create(‘Ext.data.Store‘, {        // 分页大小        pageSize : 20,        model : ‘mydata‘,        storeId : ‘mystore‘,        proxy : {            type : ‘ajax‘,            defaultActionMethods : {                create : ‘POST‘,                read : ‘POST‘, // by default GET                update : ‘POST‘,                destroy : ‘POST‘            },            url : mj.basePath + ‘service/user!datagrid.cy‘,            reader : {                root : ‘leafData‘,                totalProperty : ‘totalRows‘            }        }

 

3. or define your own proxy class

Ext.define(‘Sencha.data.PostAjax‘, {    extend: ‘Ext.data.proxy.Ajax‘,    alias: ‘proxy.postproxy‘, // must to get string reference    config: {       actionMethods: {            create : ‘POST‘,            read   : ‘POST‘, // by default GET            update : ‘POST‘,            destroy: ‘POST‘        },    }}Ext.define(‘Sencha.store.Teams‘, {    extend: ‘Ext.data.Store‘,    config: {        model: ‘Sencha.model.Team‘,        autoLoad: true,        proxy: {            type: ‘ajaxpost‘            url: ‘teams.json‘        }    }});
