这是我调用 fcmService 的页面
主页.ts
import { FcmService } from '../services/fcm.service';
constructor(
private fcm: FcmService,
){}
ngOnInit(){
this.fcm.receiveMessage()
this.messageData = this.fcm.currentMessage
}
我已将此文件导入到“src”目录中 firebase-messaging-sw.js

Firebase 已声明消息传递将无法通过 http 工作。 如果您使用特定的 IP 地址在本地提供 Web 应用程序,您可能需要使用标志--ssl
否则请确保您的构建是使用 ssl 证书托管的。
检查最后以获取参考。
此外,我相信该错误已得到修复,因此您可能希望删除“错误修复”片段
// No longer needed
_messaging.onMessage = _messaging.onMessage.bind(_messaging);
_messaging.onTokenRefresh = _messaging.onTokenRefresh.bind(_messaging);
并定期处理结果。
