import json
json_data = json.load(open(
"data.json", "r", encoding="utf-8"))
def replace_params_for_json(json_data):
result= {}
def recursive_extract(d, prefix=""): #递归函数
if isinstance(d, dict):
for key, value in d.items():
new_key = f"{prefix}.{key}" #创建新的键名
recursive_extract(value, new_key) #调用递归
elif isinstance(d,list): #如果的是列表
for index, item in enumerate(d):
new_key = f"{prefix}.[{index}]" #创建新的键名
recursive_extract(item, new_key)#调用递归
else: #如果是基本类型
result[prefix] =d #将结果添加到字典中
recursive_extract(json_data) # #调用递归
return result
result =replace_params_for_json(json_data)
print(result)
for i in result:
print(i)
最后输出所有层级key对应值value
for key, value in result.items():
print(f"{key}:{value}")
python获取多层json的key和value_mob649e815c3b9e的技术博客_51CTO博客
def update_reuqest_body_file(self,request_body_filepath):
read_json = ReadJson()
content = read_json.read_json(request_body_filepath)
# print(content)
return self.replace_params_for_json(content)
#需要理解递归的思想
def replace_params_for_json(self, json_data):
# 遍历json并替换变量
for key, value in json_data.items():
# print('%s %s' % (key, value))
if type(value) == dict:
#json类型的类型需要处理
self.replace_params_for_json(value)
elif type(value) == list:
#json list 需要特别处理
for sub_value in value:
self.replace_params_for_json(sub_value)
else:
if value is not None and type(value) == str and len(value) >= 1 and "${" in value and "}" in value:
json_data[key] = self.update_variable(value)
return json_data
前提是需要把值先存储到全局变量GLOBAL_VARIABLES中
def update_variable(self,data):
print("data: "+data)
if "${" in data and "}" in data:
v = data[data.index("${") + 2:data.index("}")]
return GLOBAL_VARIABLES.get(v)
else:
return data.strip()
