从 egg 项目配置里找到这一段代码：
https://github.com/eggjs/egg/blob/master/config/config.default.js#L205C21-L205C74
/**
* The option of `siteFile` middleware
*
* You can map some files using this options, it will response immdiately when matching.
*
* @member {Object} Config#siteFile - key is path, and value is url or buffer.
* @property {String} cacheControl - files cache , default is public, max-age=2592000
* @example
* // specific app's favicon, => '/favicon.ico': 'https://eggjs.org/favicon.ico',
* config.siteFile = {
* '/favicon.ico': 'https://eggjs.org/favicon.ico',
* };
*/
config.siteFile = {
'/favicon.ico': fs.readFileSync(path.join(__dirname, 'favicon.png')),
// default cache in 30 days
cacheControl: 'public, max-age=2592000',
};
然后在自己项目的 config.default.js 里照着加上就行，注意头部引入了 fs 和 path 这两个库。
