node.js - Express request cross-domain problem, the request interface just doesn't work

Question

I want to host the files packaged by vue on node. The static file service has also been started. Now I want to use node to handle post requests in Axios. I also configured cross-domain requests

Access-Control-Allow-Headers Neither configuration works.
The interface has a login,

Then browser cross-domain issues

Answer 1

Now that the vue project has been packaged, can’t you just put it in the public directory under the node project? Not setting app.use(express.static(path.join(__dirname, 'public'))); Well

Answer 2

You try to put app.use('/', index); below app.all('*',...).
