Python遍历文件夹 处理json文件

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...
