该请求缺少身份验证密钥（FCM 令牌）。请参阅 FCM 文档的“身份验证”部分

Question

我正在使用 Angular httppost 模块从我的 nativescript 应用程序发送 firebase 通知，它有时会发送通知，有时它会返回请求缺少身份验证密钥（FCM 令牌）的错误。请参阅 FCM 文档的“身份验证”部分

如果应用程序在前台使用邮递员，它不会收到通知，但响应仍然成功，但如果应用程序在后台，或者我按下 android 上的主页按钮，它会收到通知 这里是邮递员的一瞥

sendtoken(id, detail) {
        console.log("????????????????????????????????????????????????");
        console.log(JSON.stringify(detail.firebase_token));
        console.log(JSON.stringify(this.DataService.activeJob));
        console.log("\n\n" + detail.JobID);
        var job = this.DataService.activeJob.filter(f => detail.JobID === f.jobID)[0];

        // + detail.amount + "\n Origin : " + job.jobOrigin + "\nDestination : " + job.jobDestination

        var data = {

            notification: {
                "title": "JOB",
                "text": "Your Firm was allocated a job of amount :",
                "sound": "default"
            },
            "priority": "High",
            "to": detail.firebase_token
        };

        // alert(JSON.stringify(data));
        var ServerSettings =
            {

                serverpath: "https://fcm.googleapis.com/fcm/send"
            };

        this.headers.append("Authorization", "key=AAAA9wyBPKg:APA91bGI6dOOM42iTJNqO47xMC9QIkLHf738Sn1iVk0gbkZDND1fuP9zBW1A38DlhupDdvlsAZCJu1iNACjbVvtdZQd3ePXnq1xctwYQ3PCErchmyYMM4UvmWjeeNjn2X1IL9mgy5ioT");
        this.headers.append("Content-Type", "application/json");
        this.options.headers = this.headers;
        //this.setHeaders();
        console.log("\n\nSending to Server for Update :\n\n" + data);
        let url = ServerSettings.serverpath;

        return this.httpmodule.post(url,data, this.options);

    }

与邮递员

        "notification": {
                "title": "JOB",
                "text": "Your Firm was allocated 5",
                "sound": "default"
            },
            "priority": "High",
            "to": "dwu1TEW5sPM:APA91bEppyye2NCq5IAfnjJg95eTsnsPf4Vn3U8CLgvUjJnY7uAVs4ASZiu1RCuFKf7uzXYojAGzKQD8cflKRGvpiqhEymbhK-DB-LQi8MogWIyyIR_xOm64GIpbviWrDuVZt8Td6xZ2"

如果您总是想在应用程序运行时显示通知 在前台发送时不发送额外的参数/数据 推送通知，您需要设置 showNotificationsWhenInForeground 选项为 true：

firebase.init({
  showNotificationsWhenInForeground: true,
});

Reference from plugin docs.

编辑：

使用 Angular 在更新标头时，您应该将现有实例替换为 append 方法返回的新实例。

this.headers = this.headers.append("Authorization", "key=AAAA9wyBPKg:APA91bGI6dOOM42iTJNqO47xMC9QIkLHf738Sn1iVk0gbkZDND1fuP9zBW1A38DlhupDdvlsAZCJu1iNACjbVvtdZQd3ePXnq1xctwYQ3PCErchmyYMM4UvmWjeeNjn2X1IL9mgy5ioT").append("Content-Type", "application/json");
this.options.headers = this.headers;
