import jsonpath，json
#這裡的data目前是字典型別，記住一點外層加了引號的是字串，通俗說json相當於字典形式的字串
#將data轉化成json字串
data1=json.dumps(data)
#再檢視data1的資料型別
print(type(data1)) #輸出結果是<class 'str'>
#如果原始資料data外層加了引號，那就是json字串，轉成字典的話用json.loads(data)
#***************************************************************************************#
#jsonpath的基本用法和場景，實際工作中介面往往返回的資料是json格式，裡面資料多，層級深，現在需要獲取data資料中所有的id，應該怎麼做？
#方法一：之前常用的辦法是通過字典的方式獲取資料中“list”這個列表，然後for迴圈獲取鍵值並追加到列表中，最後輸出列表
data2=data["data"]["list"]
ids1=[]
for id in data2:
ids1.append(id["id"])
print(ids1) #輸出結果['108100000074', '108100000063', '108100000062', '108100000061', '108100000060', '108100000059', '108100000058', '108100000057', '108100000056', '108100000055']
#方法二：使用jsonpath獲取所有id
ids2=jsonpath.jsonpath(data,"$..id") #匹配資料裡面所有的id
ids3=jsonpath.jsonpath(data,"$.data.list[*].id") #匹配list下面的所有的id
print(ids2)
print(ids3) #ids2和ids3的輸出結果都是['108100000074', '108100000063', '108100000062', '108100000061', '108100000060', '108100000059', '108100000058', '108100000057', '108100000056', '108100000055']
大家學“廢“”了嗎？jsonpath還有很多方法很強大，有興趣的可以深挖哦！
每天進步一點點！
