【问题描述】:
我正在尝试在 firestore 中获取特定用户的设备令牌,该设备令牌存储在“clients”或“lawyers”集合中的令牌集合中。 当我从链中删除第二个 .collection("tokens") 时,我得到了用户对象,但是使用链中的令牌集合,我似乎无法获得任何用户(客户或律师) ) 回来,即使用户和它的令牌存在。我做错了什么
exports.onReceiveChatMessage = functions.database
.ref("/messages/{uid}")
.onCreate(async (snapshot, context) => {
const newMessage = snapshot.val();
console.log("NEW_MESSAGE", newMessage);
const senderName = newMessage.sender_name;
const messageContent = newMessage.content;
console.log("SENDER'S_NAME", senderName);
console.log("MESSAGE_BODY", messageContent);
const uid = context.params.uid;
console.log("RECEIVERS_ID", uid);
if (newMessage.sender_id == uid) {
//if sender is receiver, don't send notification
console.log("sender is receiver, dont send notification...");
return;
} else if (newMessage.type === "text") {
console.log(
"LETS LOOK FOR THIS USER, STARTING WITH CLIENTS COLLECTION..."
);
let userDeviceToken;
await firestore
.collection("clients")
.doc(uid)
.collection("tokens")
.get()
.then(async (snapshot) => {
if (!snapshot.exists) {
console.log(
"USER NOT FOUND IN CLIENTS COLLECTION, LETS CHECK LAWYERS..."
);
await firestore
.collection("lawyers")
.doc(uid)
.collection("tokens")
.get()
.then((snapshot) => {
if (!snapshot.exists) {
console.log(
"SORRY!!!, USER NOT FOUND IN LAWYERS COLLECTION EITHER"
);
return;
} else {
snapshot.forEach((doc) => {
console.log("LAWYER_USER_TOKEN=>", doc.data());
userDeviceToken = doc.data().token;
});
}
});
} else {
snapshot.forEach((doc) => {
console.log("CLIENT_USER_TOKEN=>", doc.data());
userDeviceToken = doc.data().token;
});
}
});
// console.log("CLIENT_DEVICE_TOKEN", userDeviceToken);
} else if (newMessage.type === "video_session") {
}
})
