# 运行出现这个报错
# ERROR in app: Exception on /favicon.ico [GET]# 解法
# 添加 favicon.ico 请求的处理
self.app.route(/favicon.ico, methods[GET])(self.ignore_favicon)def ignore_favicon(self):# 忽略 /favicon.ico 请求返回 404return abort(404)问题点二
# 路径问题
# 发现返回的文件夹路径没有 根目录 ‘/’# 解法
# 添加 path: 让返回是路径self.app.route(/download/path:file_name)(self.download_file)self.app.route(/show_folder/path:folder_name)(self.show_folder)self.app.route(/return_folder/path:folder_name)(self.return_folder)# 判断假设没有根目录且不是Windows的文件路径结构就添加一个 / 在左边if not file_name.startswith(/):if not re.match(.:, file_name):file_name / file_name
问题点三
# 额外发现原本埋的Bug,在返回超两层目录时路径有问题修改完以后成下面这样if folder_name .:folder_name else:# 点击返回两次会报错发现这里有问题加上下面这句不全folder_name路径# 不能直接放在判断句外面否则进到初始目录还会显示返回链接点击会报错folder_name os.path.join(FileManagementApp.gDataPath, folder_name)
额外增加了上传路径可以自己选择的功能

承接上文在这个页面 点击文件夹进入子文件夹下并显示这个文件夹下的资料点击文件可以直接下载 进入新路径结果如下点击返回可以返回上级目录 然后这个颜色靠这个设定 a:link {color:#110101;} /* 未访问链接*/a:visited {color:#00FF00;} /* 已访问链接 */a:hover {color:#FF00FF;} /* 鼠标移动到链接上 */a:active {color:#0000FF;} /* 鼠标点击时 */
新增的选择路径上传功能 当前路径下上传的文件就在这个文件夹下之前是放在默认存储路径下
如此现在算是正常上线了
