我正在使用ionic和angular.js创建一个应用程序,我在注册一个服务工作者时遇到了困难,我打算用它来添加新的应用程序安装横幅功能.我按照指示在我的app.js文件中添加以下代码,但我注意到发生了注册的任何信号,也没有任何错误.
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('service-worker.js').then(function(registration) {
//Registration was successful
console.log('ServiceWorker registration successful with scope: ',registration.scope);
}).catch(function(err) {
//registration Failed :(
console.log('ServiceWorker registration Failed: ',err);
});
}
确保您在localhost上加载页面,或者必须使用https
原文链接：https://www.f2er.com/angularjs/143709.htmlYou’ll also need to serve your code via HTTPS — Service Workers are restricted to running across HTTPS for security reasons. GitHub is therefore a good place to host experiments,as it supports HTTPS.

if ('serviceWorker' in navigator) {
[...]
} else {
console.log("this browser does NOT support service worker");
}
这可能会有所帮助：http://caniuse.com/#feat=serviceworkers
如果您想查看您的服务工作者的当前状态,您可以执行以下操作：
navigator.serviceWorker.register('/serviceworker.js',{scope: '/'})
.then(function (registration) {
var serviceWorker;
if (registration.installing) {
serviceWorker = registration.installing;
} else if (registration.waiting) {
serviceWorker = registration.waiting;
} else if (registration.active) {
serviceWorker = registration.active;
}
if (serviceWorker) {
console.log("ServiceWorker phase:",serviceWorker.state);
serviceWorker.addEventListener('statechange',function (e) {
console.log("ServiceWorker phase:",e.target.state);
});
}
}).catch(function (err) {
console.log('ServiceWorker registration Failed: ',err);
});
