Answer 1

store -> proxy- > reader -> root

Answer 2

这种格式的字符串需要配置Root属性
items:[{"userName":"18565877864","userPwd":"000000","userMobilePhone":"15914005524","userAddr":"China","userParentID":3,"userAuthor":1099511562241,"userIntroduce":"GpsServiceTesting","userType":3},{"userName":"zfp1","userPwd":"000000","userMobilePhone":"15914001003","userAddr":"ChinaGuangdongShenZhen","userParentID":3,"userAuthor":0,"userIntroduce":"GpsServiceTesting","userType":3},{"userName":"zfp2","userPwd":"000000","userMobilePhone":"15914001004","userAddr":"ChinaGuangdongShenZhen","userParentID":3,"userAuthor":0,"userIntroduce":"GpsServiceTesting","userType":4}] 
这种格式是不需要的。
[{"userName":"18565877864","userPwd":"000000","userMobilePhone":"15914005524","userAddr":"China","userParentID":3,"userAuthor":1099511562241,"userIntroduce":"GpsServiceTesting","userType":3},{"userName":"zfp1","userPwd":"000000","userMobilePhone":"15914001003","userAddr":"ChinaGuangdongShenZhen","userParentID":3,"userAuthor":0,"userIntroduce":"GpsServiceTesting","userType":3},{"userName":"zfp2","userPwd":"000000","userMobilePhone":"15914001004","userAddr":"ChinaGuangdongShenZhen","userParentID":3,"userAuthor":0,"userIntroduce":"GpsServiceTesting","userType":4}] 

Answer 3

如果你不想用root，
需要extend Ext.data.reader.Json比如
Ext.define('Ext.data.reader.JsonPWithoutRoot', {
    extend: 'Ext.data.reader.Json',
    read: function(response) {
       ...
    },
    root: '...'
});

Answer 4

我加了root 数据还是不能显示。

Answer 5

json里面要配置root，你返回的json数据里面要有相应的root，比如你的reader里面有root:'data'，那你的返回json字符串中应该是{data:[{},{}]}之类的

Answer 6

已经解决了。
不是要配置Root的问题！
我的理解还是这样{data:[{},{}]}这种格式的就要配置root,
不是这种格式的可以不用配置。
Ext4.0以上版本好像就是这样的。
