有兩種做法：os.walk()、pathlib庫，個人感覺pathlib庫的path.glob用來匹配檔案比較簡單。

下面是第二種做法的例項（第一種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:

        # 獲取所在目錄的名稱
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()

執行結果

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...

目錄結構

json file內容

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