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

使用 postman 如果应用程序在前台，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我按下 android 上的主页按钮，它会收到通知，这里是 Z03D476861AFD384510F2CB800

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 postman

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

        }

响应 postman

{
    "multicast_id": 6341518491186981658,
    "success": 1,
    "failure": 0,
    "canonical_ids": 0,
    "results": [
        {
            "message_id": "0:1569773536386430%0a6c29b00a6c29b0"
        }
    ]
}

如果您总是希望在应用程序处于前台时显示通知而不在发送推送通知时发送其他参数/数据，则需要将 showNotificationsWhenInForeground 选项设置为 true：

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

来自插件文档的参考。

编辑：

使用 Angular 更新标头时，您应该用append方法返回的新实例替换现有实例。

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