测试：

1.对象

{"a":12,"name":"haode"}

{"a":12,"name":"haode"
}

2.基本数组

[{"age":12,"name":{"women":"test","age":12,"array":[{"name":"test","age":12}]}},{"age":22,"name":"haode2"}]

解析后

[{"age":12,"name":{"women":"test","age":12,"array":[{"name":"test","age":12}]}},{"age":22,"name":"haode2"}
]

3.数组中为基本类型

[{"age":12,"name":{"women":"test","age":12,"array":[{"name":"test","age":12}],"tem":[1,2,3,4,5],"haode":"women"}},{"age":22,"name":"haode2"}]

解析后

[{"age":12,"name":{"women":"test","age":12,"array":[{"name":"test","age":12}],"tem":[1,2,3,4,5],"haode":"women"}},{"age":22,"name":"haode2"}
]
