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()

其他的读取json方法

def read_all_json(self, json_string):# 遍历json 遍历字典dict_all = {}a = json.dumps(json_string, sort_keys=True)b = json.loads(a)c = b.items()for key, v in c:dict_all[key] = vprint('%s %s' % (key, v))if type(v) == dict:self.read_all_json(v)return dict_all
