Question

我正在使用Firebase云功能在实时数据库触发事件时发送FCM。如何在{followerUid}中获得孩子（'uid'）的价值？

# improve colors
set-option -g default-terminal "screen-256color"

# set base Prefix key to ctrl-s
unbind C-b
set -g prefix C-s
bind-key -r C-s send-prefix

# reload the source config
bind-key r source-file ~/.tmux.conf \; display-message "~/.tmux.conf reloaded"

# Smart pane switching with awareness of Vim splits.
# See: https://github.com/christoomey/vim-tmux-navigator

set-option -g status-keys "emacs"

#change colour of status bar

set-option -g status-fg '#aaaaaa'

# set window split
bind-key - split-window -v  -c '#{pane_current_path}'

# Fine adjustment (1 or 2 cursor cells per bump)
bind -n S-Left resize-pane -L 2
bind -n S-Right resize-pane -R 2
bind -n S-Down resize-pane -D 1
bind -n S-Up resize-pane -U 1

# new window opens in same directory
bind c new-window -c "#{pane_current_path}"

# set window numbering to start from 1
set -g base-index 1
set -g renumber-windows on

# allow to take a pane and put it into new window
bind-key b break-pane -d

# allows ctrl-j to open tree of tmux sessions
bind-key C-j choose-tree

# Use vim keybindings in copy mode
setw -g mode-keys vi

# Setup 'v' to begin selection as in Vim
bind-key -t vi-copy v begin-selection
bind-key -t vi-copy y copy-pipe "reattach-to-user-namespace pbcopy"

# Update default binding of `Enter` to also use copy-pipe
unbind -t vi-copy Enter
bind-key -t vi-copy Enter copy-pipe "reattach-to-user-namespace pbcopy"

# History
set -g history-limit 10000

# Mouse mode
set-option -g mouse on

# Rename Tab
set-option -g set-titles on

# Terminal notifier doesnt work with tmux
set -g default-command "which reattach-to-user-namespace > /dev/null && reattach-to-user-namespace -l $SHELL || $SHELL -l"

set-option -sg escape-time 10

Answer 1

我确切地知道你在找什么......

var uid = event.data.val();
var uid1 = String(uid);

将此uid1添加到标题或正文

const payload = {
      notification: {
        title: paypes
        body:  uid1
      }
    };

Answer 2

我不确定我是否理解你要做的事情但是会被刺伤。

如果您要访问触发该功能的节点内uid的数据：

var uid = event.data.child("uid").val;

查看the documentation on handling event data。

Answer 3

由于API的最新更改。以下给出数据值。

event.before.val();

或

event.after.val();

与onWrite（）一样，在实时数据库中创建，更新或删除数据时触发。因此，它同时提供了值之前和之后的值。

Firebase Cloud功能onWrite子值
