我正在尝试使用
AJAX来检索我想在用户端显示的推送通知的详细信息,但它还没有工作.

console.log('Started',self);
self.addEventListener('install',function(event) {
self.skipwaiting();
console.log('Installed',event);
});
self.addEventListener('activate',function(event) {
console.log('Activated',event);
});
self.addEventListener('push',function(event) {
console.log('Push message',event);
var title = 'Push message';
var xhttp = new XMLHttpRequest();
xhttp.open("GET","https://www.domain.nl/devtest/1.PHP",false);
xhttp.send();
title = xhttp.responseText;
event.waitUntil(
self.registration.showNotification(data,{
'body': 'The Message','icon': 'images/icon.png'
})
);
});
当我使用GCM向客户端发送推送通知时,Chrome会在服务工作者上发出此错误：
sw.js：39未捕获的ReferenceError：未定义XMLHttpRequest
解决方法
XMLHttpRequest已被弃用,并且在Service Worker范围内不可用.您可以使用
Fetch API而不是XMLHttpRequest.
