Don't remove it; ask Express not to generate it in the first place:
不要删除它；要求 Express 首先不要生成它：

您还可以制作一个中间件来删除任何标头，如下所示：
app.use(function (req, res, next) {

Middleware snippet from: Can't get rid of header X-Powered-By:Express
中间件片段来自：无法摆脱标题 X-Powered-By:Express
function customHeaders( req, res, next ){
// Switch off the default 'X-Powered-By: Express' header
app.disable( 'x-powered-by' );
// OR set your own header here
res.setHeader( 'X-Powered-By', 'Awesome App v0.0.1' );
// .. other headers here
next();
}
app.use( customHeaders );
// ... now your code goes here
