python 使用 with open() as对文件读取写入

 with open(jsonPath,'r',encoding = 'utf-8') as load_f:
       load_dict = json.load(load_f)
       #将获取到的appToken覆盖到data_config下datajson.json文件对应的操作中,不是登陆
       load_dict[jsonkey]['appToken'] = res['data']['appToken']

 with open(jsonPath,'w',encoding = 'utf-8') as dump_f:
       json.dump(load_dict,dump_f,indent = 3,sort_keys = True)

#执行接口时，从datajson.json的相应操作中，获取到最新的appToken
