Python遍历文件夹 处理json文件的方法

有两种做法：os.walk()、pathlib库，个人感觉pathlib库的path.glob用来匹配文件比较简单。

下面是第二种做法的实例（第一种做法百度有很多文章）：

from pathlib import Pathimport jsonanalysis_root_dir = "D:\\analysis_data\json_file"store_result="D:\\analysis_data\\analysis_result\\dependency.csv"def parse_dir(root_dir):  path = Path(root_dir)  all_json_file = list(path.glob('**/*.json'))  parse_result = []  for json_file in all_json_file:    # 获取所在目录的名称    service_name = json_file.parent.stem    with json_file.open() as f:      json_result = json.load(f)    json_result["service_name"] = service_name    parse_result.append(json_result)  return parse_resultdef write_result_in_file(write_path , write_content):  with open(write_path,'w') as f:    f.writelines("service_name,action,method,url\n")    for dict_content in write_content:       url = dict_content['url']       method = dict_content['method']       action = dict_content['action']       service_name = dict_content['service_name']       f.writelines(service_name + ","+ action+","+method + ","+ url+"\n")def main():  print("main begin...")  parse_result = parse_dir(analysis_root_dir)  print(parse_result)  write_result_in_file(store_result,parse_result)  print("main finished...")if __name__ == '__main__':  main()

运行结果

main begin...[{'url': '/rest/webservice/v1/dosomthing', 'method': 'post', 'action': 'create', 'service_name': 'WebSubService'}, {'url': '/rest/webservice/v1/dosomthing', 'method': 'post', 'action': 'create', 'service_name': 'WebSubService01'}, {'url': '/rest/webservice/v1/dosomthing', 'method': 'post', 'action': 'create', 'service_name': 'WebSubService02'}, {'url': '/rest/webservice/v1/dosomthing', 'method': 'post', 'action': 'create', 'service_name': 'WebSubService03'}, {'url': '/rest/webservice/v1/dosomthing', 'method': 'post', 'action': 'create', 'service_name': 'WebSubService04'}, {'url': '/rest/webservice/v1/dosomthing', 'method': 'post', 'action': 'create', 'service_name': 'WebSubService05'}]main finished...

目录结构

json file内容

{ "url":"/rest/webservice/v1/dosomthing", "method":"post", "action":"create"}
