我正在尝试从GCM接收推送消息。我只是按照以下方式注册了服务工作者,遵循了教程:
function urlB64ToUint8Array(base64String) {
const padding = '='.repeat((4 - base64String.length % 4) % 4);
const base64 = (base64String + padding)
.replace(/\-/g, '+')
.replace(/_/g, '/');
const rawData = window.atob(base64);
const outputArray = new Uint8Array(rawData.length);
for (let i = 0; i < rawData.length; ++i) {
outputArray[i] = rawData.charCodeAt(i);
}
return outputArray;
}
var subscribeForPush = function() {
navigator.serviceWorker.ready.then(function(serviceWorkerRegistration) {
serviceWorkerRegistration.pushManager.subscribe({
userVisibleOnly: true,
applicationServerKey : urlB64ToUint8Array('<API-KEY>')
})
.then(function(subscription) {
console.log("Subscription for Push successful: ", subscription);
})
.catch(function(error) {
console.log("Subscription for Push failed", error);
});
});
};
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('/sw.js').then(function(registration) {
// Registration was successful
console.log('ServiceWorker registration successful with scope: ', registration.scope);
subscribeForPush();
}).catch(function(err) {
// registration failed :(
console.log('ServiceWorker registration failed: ', err);
});
});
}
现在,我获取了设备ID ("cw4jK8NhJgY:APA91bHr64E_kSdh7kN_VjcZRKulPf8KPLJLBjtnHI2qkYzx3-I9aUhunjzVcJjLtkHl9zvN8ys80gADK8tV8SueLX1R2jS0xgrf1Ur6cDw3jNjloUJp8PtWaIN-cEKXj69TZ9-D2Hiw")
在我的服务工作者文件中,我只需监听推送消息即可:
self.addEventListener('push', function(event) {
console.log(event)
});
我可以使用终端向GCM发送消息并获取消息:
{"multicast_id":4983340130324592129,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1483043226210433%cc9b4facf9fd7ecd"}]}
但我不知道为什么在推送监听器中看不到日志?我已经被卡在这个问题上超过两天了。有人可以帮我吗?我是在本地主机上进行的。
