参数列表

• import_name: the name of the application package，感觉没什么用
• static_url_path: can be used to specify a different path for the
  static files on the web. Defaults to the name
  of the static_folder folder。描述静态文件（css）的目录
• static_folder: The folder with static files that is served at
  static_url_path. Relative to the application root_path
  or an absolute path. Defaults to 'static'. 刚刚那个参数目录下，静态文件具体的目录。
• static_host: the host to use when adding the static route.
  Defaults to None. Required when using host_matching=True
  with a static_folder configured. 感觉没什么用。
• host_matching: set url_map.host_matching attribute.
  Defaults to False.感觉没什么用。
• subdomain_matching: consider the subdomain relative to
  :data:SERVER_NAME when matching routes. Defaults to False. 感觉没什么用
• template_folder: the folder that contains the templates that should
  be used by the application. Defaults to
  'templates' folder in the root path of the
  application. 渲染模板的位置
• instance_path: An alternative instance path for the application.
  By default the folder 'instance' next to the
  package or module is assumed to be the instance
  path.
• instance_relative_config: if set to True relative filenames
  for loading the config are assumed to
  be relative to the instance path instead
  of the application root.
• root_path: The path to the root of the application files.
  This should only be set manually when it can’t be detected
  automatically, such as for namespace packages. 没什么用，一般不动。

实际代码

我的打包好的前端文件目录是dist文件，在/data/yzc/FedWeb/web_font/下。

1

dir_path_base='/data/yzc/FedWeb/web_font/'
app = Flask(__name__,
            root_path=dir_path_base+"dist",
            )  

结果
raise TemplateNotFound(template)

2

dir_path_base='/data/yzc/FedWeb/web_font/'
app = Flask(__name__,
            template_folder = dir_path_base+"dist"            
            )  

结果是找不到静态文件，找到了template文件index.html，还行。

127.0.0.1 - - [20/Jul/2023 13:51:32] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [20/Jul/2023 13:51:32] "GET /assets/index-2edf8bd1.js HTTP/1.1" 404 -
127.0.0.1 - - [20/Jul/2023 13:51:32] "GET /assets/index-9021f5e4.css HTTP/1.1" 404

那么把静态文件的路径写上就搞定了

dir_path_base='/data/yzc/FedWeb/web_font/'
app = Flask(__name__,
            static_folder=dir_path_base+"dist/assets/",
            template_folder = dir_path_base+"dist"            
            )  

结果成功！
