flask示例项目：基于文件系统动态生成路由(window环境版)

import os import importlib import inspect from stat import * class Route(): # 构造函数，传入app,项目路径，应用名称 def __init__(self, app, project_path, route_dir, file_dir): self.__app = app # flask 的app self.__project_path = project_path # 当前的项目路径(通过在main中传入__file__) self.__route_dir = route_dir # 存放route的目录(指定存放route的目录) self.__file_dir = file_dir # 需要生成路由的目录(指定route目录下需要生成路由的目录) self.route_start_path = self.__project_path + "/{0}/".format(self.__route_dir) + self.__file_dir def build(self): self.__make(self.route_start_path) # 需要生成路由的起始目录 def __make(self,top): for f in os.listdir(top): pathname = os.path.join(top, f) try: mode = os.stat(pathname).st_mode # python获取文件的状态，用于进一步判断是否文件 except PermissionError: continue else: if S_ISDIR(mode) and not f.startswith("__"): # 如果是文件夹且不以"__"开头，则继续获取下层内容 self.__make(pathname) elif S_ISREG(mode): # 如果是文件，则生成路由配置 self.__gen_route(pathname,f.replace(".py","")) else: pass def __gen_route(self,pathname,name): moduleStr = pathname.replace(self.__project_path+"/","").replace(".py","").replace("/",".").replace("\\",".") moduleObj = importlib.import_module(moduleStr) for classStr in dir(moduleObj): if not classStr.startswith("__") and classStr.lower()==name.lower(): classObj = getattr(moduleObj, classStr) obj = classObj() urlPath = pathname.replace(self.__project_path,"").replace("{0}/".format(self.__route_dir),"").replace(".py","").replace("\\","/").lower() for methodName in dir(classObj): if not methodName.startswith("__"): print('产生路由：', urlPath+"/"+methodName.lower()) self.__app.add_url_rule(urlPath+"/"+methodName.lower(), endpoint=urlPath.replace("/","-")+"-"+methodName, view_func=getattr(obj, methodName), methods=["GET","POST"])
