Project description
ejson
An smart json,similar to the jquery, read and update the json data.
一个小巧的、完全无依赖的类似jquery写法的读取和更改json的工具,可以按照json的层级或者某个属性读取json数据。
Installing aelog
pip install eqjson
Usage
假如json数据如下:
[
{
'object':{
'name':'myLittleObject',
'value':[
{
'key2':'value2',
'key3':'value3',
'key1':'value1'
},
{
'key33':'value33',
'key1':'value11'
},
{
'key333':'value333',
'key1':'value111'
}
],
'type':'list',
'valueAsString':[
'one',
'two'
]
}
}
]
from eqjson import EasyQueryjson
# 实例化
ejson_obj = EasyQueryjson(json_doc)
# 查询
ejson_obj.get_value("object.name")
ejson_obj.get_value("object.valueAsString.0")
# update
ejson_obj.change_value("object.name", "updatename")
ejson_obj.change_value("object.value.2", ["five", "four"])
# add
ejson_obj.append_value("object.valueAsString", "three")
ejson_obj.append_value("object.valueA", {"test":456})
# remove
ejson_obj.remove_value("object.valueAsString")
ejson_obj.remove_value("object.value")
# 具体的查询参数详情如下
基本用法:
- 如果要获取name值:则写法为
0.object.name
- 如果json最外层是{}获取name值:则写法为
object.name
- 如果要获取valueAsString中的第一个值:则写法为
0.object.valueAsString.0
- 如果json最外层是{}获取valueAsString中的第一个值:则写法为
object.valueAsString.0
- 获取value列表中的第一个值的key1值:则写法为
0.object.value.0.key1
- 获取value列表中的所有的key1值:则写法为
0.object.value.key1
, 则结果为['value1','value11', 'value111']
高级用法:
- 支持通过属性确定值,如果json是无序的,要获取key1值为value1所在节点的key3的值,则写法为
0.object.value[key1=value1].key3
- 支持通过多属性确定值,比如要获取key1值为value1,key2值为value2,所在节点的key3的值,则写法为
0.object.value[key1=value1,key2=value2].key3
- 支持多层属性,比如要获取name为myLittleObject的以上的值:则写法为
[name=myLittleObject].object.value[key1=value1].key3
