api响应中json或xml的可读视图.Yii2

In guides在可读视图中显示api的响应。我想知道，这样做只是为了显示响应的结构，还是有一种方法可以使视图可读。

终端示例：我的代码：中的响应

"date_imported":"2016-03-19 18:30:22"}],"_links":{"self":{"href":"http://localhost/tweets?page=1"},"next":{"href":"http://localhost/tweets?page=2"},"last":{"href":"http://localhost/tweets?page=23"}},"_meta":{"totalCount":450,"pageCount":23,"currentPage":1,"perPage":20}}

docs:相同代码的响应

"_links": {
        "self": {
            "href": "http://localhost/users?page=1"
        },
        "next": {
            "href": "http://localhost/users?page=2"
        },
        "last": {
            "href": "http://localhost/users?page=50"
        }
    },
    "_meta": {
        "totalCount": 1000,
        "pageCount": 50,
        "currentPage": 1,
        "perPage": 20
    }
}

它只是用于演示，而实际响应具有字符串视图，还是我做错了什么？
