我正在尝试从Firebase函数中发送FCM,但每次都会收到以下错误:
await admin.messaging().sendToDevice(registrationToken, message)
我遵循了this post, of the same topic的建议,没有帮助。指向文章中的另一个链接Add the Firebase Admin SDK to your server,因为我使用的是Firebase Server,它并没有太大帮助。
本文与Sending FCM using Firebase Functions相同,我使用的是相同的代码(FCM代码),并且存在相同的错误。
这是完整的错误:
Error sending message: { Error: An error occurred when trying to authenticate to the FCM servers. Make sure the credential used to authenticate this SDK has the proper permissions. See https://firebase.google.com/docs/admin/setup for setup instructions. Raw server response: "<HTML>

</BODY>
</HTML>
". Status code: 401.

好的,无关但相关,我找到了答案...
gcp-the-caller-does-not-have-a-permission
基本上,按照these的说明进行添加
Firebase管理员

我是如何解决的:
这仅用于测试,请记住在部署函数时删除凭据!
admin.initializeApp({
credential: admin.credential.cert(
"route/to/generatedJSON.json"
),
});
const messaging = admin.messaging();
