 CONFIG_URL is used to automatically download remote configuration files. For example, if it is inconvenient to modify the configuration file on a certain platform, you can upload the configuration file to a hosting service and provide a direct link for uni-api to download. CONFIG_URL is this direct link. If you are using a locally mounted configuration file, you do not need to set CONFIG_URL. CONFIG_URL is used in situations where it is inconvenient to mount the configuration file.

 CONFIG_URL 就是可以自动下载远程的配置文件。比如你在某个平台不方便修改配置文件，可以把配置文件传到某个托管服务，可以提供直链给 uni-api 下载，CONFIG_URL 就是这个直链。如果使用本地挂载的配置文件，不需要设置 CONFIG_URL。CONFIG_URL 是在不方便挂载配置文件的情况下使用。
