ExtJs4 - Store BaseParams配置属性？ [英] ExtJs4 - Store baseParams config property?

问题描述

在extjs3.x中，我使用了商店 baseParams config属性来指定用于加载商店的参数。

此属性不再存在于extjs 4.我应该怎么做，而不是这个？

In extjs3.x I used the stores baseParams config property to specify parameters used to load the store.
This property no longer exists in extjs 4. What should I do instead of this?

另外在extjs3中，我能够指定商店代理是一​​个 GET 或 POST 方法通过使用代理方法配置属性。我该怎么办呢？

Also in extjs3 I was able to specify wether the stores proxy was a GET or a POST method by using the proxy method config property. What should I do instead of this?

我的ExtJs 3代码 - >

My ExtJs 3 code ->

   var store = new Ext.data.JsonStore({
        root: 'Data',
        baseParams: {
           StartDate: '',
           EndDate: '''
        },//baseParams
    proxy: new Ext.data.HttpProxy({
        url: 'Time/Timesheet',
        method: 'POST'
    })//proxy
});//new Ext.data.JsonStore

推荐答案

你需要使用'extraParams'代理属性代替Ext 3中的baseParams。ExtJS 4中的等效JsonStore如下所示：

You need to use the 'extraParams' proxy property in place of the baseParams one from Ext 3. An equivalent JsonStore in ExtJS 4 looks like this:

Ext.define('YourModel', {
    extend: 'Ext.data.Model',
    fields: ['field1', 'field2']
}); 

var store = new Ext.data.Store({
    model: 'YourModel',
    proxy: {
        type: 'ajax',
        url : 'Time/Timesheet',
        root: 'Data',
        extraParams: {
            StartDate: '',
            EndDate: ''
        }
    }
});

据我所知，HTTP传输方法是根据RESTful原则自动设置的，试图完成。例如，如果您加载存储，则使用GET请求;创建新记录使用POST等。

As far as I know, the HTTP transport method is set automatically according to RESTful principles according to what you're trying to accomplish. For example, if you load the store a GET request is used; creating a new record uses a POST, etc.

如果需要，您可以覆盖此代码，通过覆盖代理的actionMethods属性：

You can override this if necessary though, by overriding the actionMethods property of the proxy:

var store = new Ext.data.Store({
    model: 'YourModel',
    proxy: {
        type: 'ajax',
        url : 'Time/Timesheet',
        root: 'Data',
        actionMethods: {
            read: 'POST'
        },
        extraParams: {
            StartDate: '',
            EndDate: ''
        }
    }
});
