firebase functinos cookie only __session

https://firebase.google.com/docs/hosting/manage-cache?hl=zh-cn#using_cookies

将 Firebase 托管与 Cloud Functions 或 Cloud Run 搭配使用时，Cookie 通常会从传入的请求中剥离出来。这是实现高效的 CDN 缓存行为所必需的。只有特别指定的 __session Cookie 可以传入应用执行过程中。 __session Cookie（如果存在）会自动成为缓存键的一部分，也就是说，使用不同 Cookie 的两个用户绝不会收到彼此的已缓存响应。只有在您的应用根据用户授权提供不同的内容时，您才能使用 __session Cookie。

javascript firestore object sort


  const bookListsQuery = await modules.firestore.collection('books')
    .get();

  const sortedObj = Object.values(bookListsQuery.docs).sort(function(a, b){
    console.log('a %s  b %s', a.data().order, b.data().order)
    return Number(a.data().order) > Number(b.data().order);
  });
        
  sortedObj.forEach(function(doc){
    console.log(doc.data())
  });

other way

object use map to array, then it sorted.


  const bookListsQuery = await modules.firestore.collection('books')
    .get();

  const sortedArr = bookListsQuery.docs.map(function (doc) {  // 轉換成array
    return doc.data()
  });

  sortedArr.sort(function compare(a, b) {
     return a.order > b.order; // 升 小->大
  });

  sortedArr.forEach(function(data){
    console.log(data.data())
  })

Sorting multiple object properties with JavaScript

let students = [{

  grade: 10
},{

  lastName: 'Appletree',
  grade: 11
},{
  firstName: 'Shooter',
  lastName: 'Appletree',
  grade: 12
}];


let sortBy = [{
  prop:'grade',
  direction: -1
},{
  prop:'lastName',
  direction: 1
}];


array.sort(function(a,b){
  let i = 0, result = 0;
  while(i < sortBy.length && result === 0) {
    result = sortBy[i].direction*(a[ sortBy[i].prop ].toString() < b[ sortBy[i].prop ].toString() ? -1 : (a[ sortBy[i].prop ].toString() > b[ sortBy[i].prop ].toString() ? 1 : 0));
    i++;

firestore import

使用 https://github.com/dalenguyen/firestore-backup-restore
base on https://github.com/dalenguyen/firestore-import-export

能處理timestamp

filestore2json json2filestore

https://gist.github.com/sturmenta/cbbe898227cb1eaca7f85d0191eaec7e#gistcomment-2837988

ok can use. good job.

timestamp have error.

Firebase auth and upload image

Firebase Database Rules

https://www.oxxostudio.tw/articles/201904/firebase-realtime-database-rules.html

https://angularfirebase.com/lessons/understanding-firebase-database-rules-by-example/

firebase hosts cloudflare

ERR_TOO_MANY_REDIRECTS

Or

Error 526

SSL change Full or Full (strict)

just try

firebase database security rule

best easy know

1、auth != null -- only auth pass user ( login success user)

2、$uid === auth.uid -- usually only data owner can read or modify
$userId === auth.uid

==========
1、only admins group can wirte data

a. Database data
add admins -> add uid:true (uid -> user in admins group)

b. Database rule
add
{
"rules": {

"admins":{
".read" : "auth != null && root.child('admins').hasChild(auth.uid)",
".write" : "auth != null && root.child('admins').hasChild(auth.uid)"
}

}
}

now uid in admis, can modify admins

If items only admis can add or modify, everyone can read.

{
"rules": {

"items":{
".read" : "auth != null ",
".write" : "auth != null && root.child('admins').hasChild(auth.uid)"
}

}
}

2、maybe your want user in admins group and some special oooooxxxx

{
"rules": {

"items":{
".read" : "auth != null ",
".write" : "auth != null && root.child('admins').hasChild(auth.uid) && root.child('admins').child(auth.uid).val()==="oooooxxxxxx" "
}

}

ionic2 firebase FCM FCM_TOKEN Device_token Sender_id

https://medium.com/@ankushaggarwal/push-notifications-in-ionic-2-658461108c59#.ff6hz41ot

．sender_id who is sender or This guy is send message.

．FCM_token (api_key) it's right to use FMC, who get token, then can send

．Device token this device (which device)

Where is come from?

．sender_id 、 FCM_token from FCM (firebase)

．Device_token from device

How to get?

．sender_id 、 FCM_token ： login firebase console -> settings -> colud messageing

．Device_token ： If ionic2, when you use
Push @ionic/cloud-angular push.register().then(t: PushToken)
this time get Push Token. see video 7:54

So how to work? (If see youtube video, I guess)

．FCM_token： Who take token, who can send message. FCM get FCM_token, then send message to send_id under all register.

．sender_id： App or reciver must have this info, when message come from FCM into Phone, then check send_id is correct or not.

．Device_token：
A、Device must send(register) phone's Device_toke to FCM sender_id, then register info(device_token) under send_id. If not register, send_id can't know any devices.

B、Sometime send message to only one device, must use FCM_token + Device_token then only send to one device.

(This Video 9:38 bottom have "Device Options")

(https://github.com/aggarwalankush/push-notification-server
AndroidPush.java see code have "YOUR_DEVICE_TOKEN" )

firebase offline-online somethings

Now try to use firebase for design app. But get somethings about :

1. At offline, you can read, but add, delete, edit can not, this "can not" is snapshot that need to online sync, then get data.

2. So firebase example is use models or objects to keep data, but you change activeity or clearn app, then objects data loss. maybe can use Serialization, but not good idea.

3. Can't control local database. This is fun, maybe firebase no local database or other methods for offline. Some app need offline, for counting data, CURD data, keep then sync, counting age.

mm, I think my java, android app and firebase knowledge, I don't real understand or think error. So just writer this message for keep.

firebase auth SimpleLogin when offline auth check

>> firebase response
Great question. We are actually putting the finishing touches on login v2 and I think you will be happy with the offline improvements it brings. Ultimately, you are running into issues with what you are trying to do because it cannot be done with the current API. However, with our upcoming login refresh, we will persist session tokens on the client, allowing you to authenticate via custom or simple login without any internet connection. We are still a couple weeks out from finishing this project and making it production-ready, but keep an eye out on this group for announcements.

Storing User Data

Internally, Simple Login generates JWT auth tokens after authenticating against the appropriate provider. It then calls Firebase.auth() with those tokens. It does not store profile or state information in Firebase. In order to persist user data we'll have to save it to our Firebase.

=================
Firebase.auth() in firebase-client-jvm-1.0.18.jar/com/firebase/client/Firebase.class

can not decomplier, for understand how to save data. ....
