Set the first parameter of the setHeaders option to Koa Response

[YSMJ1994]

I think most people are used to using " Koa Response" in koa or not "Node Response".
Just like use ctx.response.set('Cache-Control', 'max-age=0') or not ctx.res.setHeader(...).
Because Koa officially states Bypassing Koa's response handling is not supported

This is also a problem for me;

if (!ctx.response.get('Cache-Control')) ctx.set('Cache-Control', 'max-age=' + (maxage / 1000 | 0));

I need to make sure there are no Cache-Control headers that will collide with Akamai but this currently can't be controlled with an options flag

staticServe(__dirname + "/public", {
setHeadears: function (res, path, stats) {
res.setHeader("Cache-Control", "max-age=60");
},
})

I want to ask why this is not effective？
