How to add headers on Nuxt static files response?

问题

I have a json file on static folder and I'm trying to access it from another web site, but I'm having problem with the CORS.

How can I add headers (like Access-Control-Allow-Origin) on the static files response?

I tried this https://github.com/nuxt/nuxt.js/issues/2554#issuecomment-363795301, but didn't work for static files.

module.exports = function (req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Headers', '*');
    res.setHeader('Access-Control-Allow-Methods', '*');
    next()
}

Nuxt has a build in render property option, that you can use inside the nuxt.config.js file.

If you want to add Access-Control Headers for static files just use the setHeaders function.

See https://nuxtjs.org/api/configuration-render#static.

In the background Nuxt uses the serve-static package (also for other options).

Example:

render: {
   static: {
     setHeaders(res) {
       res.setHeader('X-Frame-Options', 'ALLOWALL')
       res.setHeader('Access-Control-Allow-Origin', '*')
       res.setHeader('Access-Control-Allow-Methods', 'GET')
       res.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
  }
}

If you are using axios to make HTTP calls you might want to use Nuxt version of Axios. There you can easily use option proxy in combination with Proxy Module
