service-worker - PWA - 子目录中的 service-worker JS

Question

我试图将我的 sw.js 文件放在子目录而不是根目录中。但随后我收到一条错误消息，指出无法安装服务人员。

是否真的有必要将该文件放在根目录中，还是我只是遗漏了什么？

JS 代码:

if ('serviceWorker' in navigator) {

    navigator.serviceWorker.register('/js/pwa/sw.js', { scope: '/js/pwa' }).then(function(reg) {
        console.log('Successfully registered. Scope is ' + reg.scope);
    }).catch(function(error) {
        console.log('Registering failed ' + error);
    });
} else {
    console.log('Service worker can not be registered on this device');
}

Answer 1

如果我做同样的事情，我会得到以下错误

Registering failed SecurityError: Failed to register a ServiceWorker: The path of the provided scope ('/js/pwa') is not under the max scope allowed ('/js/pwa/'). Adjust the scope, move the Service Worker script, or use the Service-Worker-Allowed HTTP header to allow the scope.

下面的部分看起来很奇怪

{ scope: '/js/pwa' }

请按如下操作

{ scope: '/js/pwa/' }
