如何从Spring Boot正确地提供service-worker.js？

Question

The browser complains the file is behind a redirect:

DOMException: Failed to register a ServiceWorker: 
The script resource is behind a redirect, which is disallowed.

What i tried so far:

Service worker on `static/service-worker.js`
Service worker on @GetMapping("/service-worker.js") @ResponseBody

In both cases i can read the file from brower in /service-worker.js but the registration fails with the same exception.

EDIT: (This is the registration I had problems with)

<script>
if ('serviceWorker' in navigator) {
    console.log("Will the service worker register?");
    navigator.serviceWorker.register('service-worker.js')
        .then(function(reg){
            console.log("Yes, it did.");
        }).catch(function(err) {
        console.log("No it didn't. This happened: ", err)
    });
}
</script>

Answer 1

My script trying to register was in /store/All . Registering with navigator.serviceWorker.register('service-worker.js') was calling /store/service-worker.js which was being redirected according to a rule I had programmed in my controller.

The right call should be: navigator.serviceWorker.register('/service-worker.js') This ensures we call the service-worker.js in root and not in the same path as the current page.

tl;dr I was missing a /
