[英]Firebase Cloud function: how many users can the same function (onCall) serve? With how many resources can it serve them?
[英]firebase cloud functions - https.onCall(…) can Context.Auth be used?
我需要建议,因为我从未尝试过这种组合:
我想使用谷歌auth2身份验证和“保护”云功能只能由Android应用程序调用,如果atuh只有效。
最诚挚的问候伊万
对于示例,这是我的'addTickets'场景的云函数:
=== index.js:===
exports.addTickets = functions.https.onCall((data, context) => {
// data comes from client app
const buyingRecord = data;
console.log(‘buyingRecord: ‘ + JSON.stringify(buyingRecord));
return tickets.updateTicketsAmmount(buyingRecord)
.then((result)=>{
tickets.addTicketsBuyingRecord(buyingRecord);
result.userid = buyingRecord.userid;
result.ticketsCount = buyingRecord.ticketsCount;
return result;
});
});
====== tickets.js =======
exports.updateTicketsAmmount = function(buyingRecord) {
var userRef = db.ref(‘users/’ + buyingRecord.userid);
var amountRef = db.ref(‘users/’ + buyingRecord.userid + ‘/ticketsAmount’);
return amountRef.transaction((current)=>{
return (current || 0) + buyingRecord.ticketsCount;
})
.then(()=>{
console.log(“amount updated for userid [“ + buyingRecord.userid + “]”);
return userRef.once(‘value’);
})
.then((snapshot)=>{
var data = snapshot.val();
console.log(“data for userid [“ + snapshot.key + “]:” + JSON.stringify(data));
return data;
});
}
exports.addTicketsBuyingRecord = function(buyingRecord) {
var historyRef = db.ref(‘ticketsBuyingHistory’);
var newRecordRef = historyRef.push();
return newRecordRef.set(buyingRecord)
.then(()=>{
console.log(‘history record added.’);
return newRecordRef.once(‘value’);
})
.then((snapshot)=>{
var data = snapshot.val();
console.log(‘data:’ + JSON.stringify(data));
return data;
});
}
如果只希望经过身份验证的用户调用可调用函数,则只需检查context.auth.uid
存在。 如果用户未经过身份验证,则不会有uid。
