"key[]":{}，后面是JSONObject | 查询数组 | ["User[]":{"User":{"sex":1}}](http://139.196.140.118:8080/get/{"User[]":{"count":3,"User":{"sex":1}}})，查询性别为女的一个User数组，请求完成后会变为 "User[]":{"0":{"User":{"id":38710,"sex":1,"name":"Tommy"...}}, "1":{"User":{"id":82001,"sex":1,"name":"Lemon"...}} ...}
|

"key{}":[]，后面是JSONArray，作为key可取的值的选项 | 匹配选项范围 | "id{}":[38710,82001,70793]，查询id符合38710,82001,70793中任意一个的Object。一般用于查询一个数组。请求[{"[]":{"User":{"id{}":[38710,82001,70793]}}}](http://139.196.140.118:8080/get/{"[]":{"count":3,"User":{"id{}":[38710,82001,70793]}}})会返回一个User数组，例如上面那个。
