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 Path
import json

analysis_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_result

def 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"
}
