我正试图在我的Nuxt JS网站中实现一个自定义的内置服务工作程序。生成网站后出现以下错误:

Cannot read property 'register' of undefined
function Notify (siteOptions) {
  /* Set Dependancies */
  this.siteOptions = siteOptions /* Register Applicant */
  this.register()
} /** * Register Service Worker */
Notify.prototype.register = function () {
  /** * Test Registration */
  navigator.serviceWorker.register('Notify-service-worker.js').then(function (registration) {
    console.log('SW: Available')
  }).catch(function (error) {
    console.error('SW: Not Available', error)
  })

看来这是引起问题的行:

navigator.serviceWorker.register('Notify-service-worker.js')

答案 0 :(得分:0)

在注册之前检查当前浏览器是否支持服务人员是best practice

if ('serviceWorker' in navigator) {
  // Only call navigator.serviceWorker.register() if that's true.
}
