Golange error: Resource interpreted as script but transferred with MIME type text

This is because the Content-Type value of the Javascript HTTP Response sent from the server is text/plain (default .) What you expect to return is compatible with the Javascript type.

Solution: Add Content-Type in the returned field of the server.
: Application/X-Javascript

The specific solution in golang is as follows:

Func router (w http. responsewriter, R * HTTP. request) {R. parseform () URL: = R. URL. pathswitch {Case "/demo_workers.js" = URL: W. header (). add ("Content-Type", "application/X-JavaScript") T, _: = template. parsefiles ("demo_workers.js") T. execute (W, nil) Default: T, _: = template. parsefiles ("demo_workers.html") T. execute (W, nil )}}
