Resolve cross-domain issues with the node. JS Express Framework;

Write down the following code before referencing the route:

App.use (' * ', function (req, res, next) {
Res.header ("Access-control-allow-origin", "*");
Res.header ("Access-control-allow-headers", ' Content-type,content-length, Authorization, Accept,x-requested-with ') ;
Res.header ("Access-control-allow-methods", "put,post,get,delete,options");
Res.header ("x-powered-by", ' 3.2.1 ')
Next ();
});

You can use Ajax to complete cross-domain access.
