"Certificate object must contain a string "private_key" 属性" 尝试发送推送通知时
"Certificate object must contain a string "private_key" property" when trying to send push notification
我正在尝试在将某些内容添加到我的 firebase 数据库后发出推送通知。
我参考 this blog 完成了此操作。如果我的数据库中添加了某些内容,我会尝试发出推送通知
在 firebase 中创建数据库的代码如下:
// I'm passing my message content and user here it will create a child in database
public static void sendNotificationToUser(String user, final String message) {
DatabaseReference ref;
ref = FirebaseDatabase.getInstance().getReference();
final DatabaseReference notifications = ref.child("notificationRequests");
Map notification = new HashMap<>();
notification.put("username", user);
notification.put("message", message);
notifications.push().setValue(notification);
}
这是我的 index.js 脚本代码:
var firebase = require('firebase-admin');
var request = require('request');
var API_KEY = ".AAA...iEmIG";
var serviceAccount = require(".google-services.json");
firebase.initializeApp({
credential: firebase.credential.cert(serviceAccount),
databaseURL: "https://chitchatapp-73060.firebaseio.com/"
});
ref = firebase.database().ref();
function listenForNotificationRequests() {
var requests = ref.child('notificationRequests');
requests.on('child_added', function (requestSnapshot) {
var request = requestSnapshot.val();
sendNotificationToUser(
request.username,
request.message,
function () {
requestSnapshot.ref.remove();
}
);
}, function (error) {
console.error(error);
});
};
function sendNotificationToUser(username, message, onSuccess) {
request({
url: 'https://fcm.googleapis.com/fcm/send',
method: 'POST',
headers: {
'Content-Type': ' application/json',
'Authorization': 'key=' + API_KEY
},
body: JSON.stringify({
notification: {
title: message
},
to: '/topics/user_' + username
})
}, function (error, response, body) {
if (error) { console.error(error); }
else if (response.statusCode >= 400) {
console.error('HTTP Error: ' + response.statusCode + ' - ' + response.statusMessage);
}
else {
onSuccess();
}
});
}
listenForNotificationRequests();
当我尝试部署它时,出现如下错误,我该如何解决

是什么导致了这个错误,我该如何解决?
您的 google-services.json
文件似乎有问题。
您是否按照博客 post 的指示下载了该文件?如果是这样,你把它放在哪里了?并且您确定匹配中放置文件的路径吗?我希望是这样的:
var serviceAccount = require("./google-services.json");
在您的评论中,您说您正在使用 Cloud Functions。在那种情况下,您的代码在 Google 的环境中运行,您甚至不需要 google-services.json
。来自这个样本:
firebase.initializeApp(functions.config().firebase);
