Nginx 只允许Cloudflare CDN IP访问

现有一个简单的需求，需要用户弹窗选择一个铃音，要求在正式的确认之前就能播放对应的音乐作预听，微信小程序picker（mode = selector）可以实现选择确认功能，但只有点击确认后的bindchange事件，没有选择变化事件。根据微信文档，在mode = multiSelector时，有多了一个bindcolumnchange事件，灵光一闪，只有一列的multiSelector不就是selector？那不就可以把multiSelector当selector用？

wxml:

          <view class="option">铃声: 
          <picker mode="multiSelector" range="{{[ringtones]}}" data-alarmid="{{item.id}}" bindcolumnchange="bindRingtoneSelect" bindchange="bindRingtoneChange">
            <view class="picker">{{ringtones[item.ringtoneIndex]}} <text class="picker-selector"> ❯</text> </view> 
          </picker>
          </view>

特别注意其中：ringtones一维数组，调整为：[ringtones]引用。

js:

  bindRingtoneSelect: function(e) {
    proto.sendPlayMusic(e.detail.value);
  },

  bindRingtoneChange:function(e) {
    proto.sendSaveMusic(e.detail.value);
  },

实验效果完美解决~~

Debian默认root帐号shell无色彩解决

默认root帐号的shell无色彩

修改.bashrc文件为：

# Note: PS1 and umask are already set in /etc/profile. You should not
# need this unless you want different defaults for root.
 PS1='${debian_chroot:+($debian_chroot)}\h:\w\$ '
# umask 022

# You may uncomment the following lines if you want `ls' to be colorized:
 export LS_OPTIONS='--color=auto'
 eval "$(dircolors)"
 alias ls='ls $LS_OPTIONS'
 alias ll='ls $LS_OPTIONS -l'
 alias l='ls $LS_OPTIONS -lA'

# Some more alias to avoid making mistakes:
# alias rm='rm -i'
# alias cp='cp -i'
# alias mv='mv -i'

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
    # We have color support; assume it's compliant with Ecma-48
    # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
    # a case would tend to support setf rather than setaf.)

总结

  1. 可以通过脚本自动获取并验证更新代理节点

  2. 还有更多的搜索方法：

      protocol=="socks5" && "Version:5 Method:No Authentication(0x00)" && after="1900-01-01" && country="CN"
     "“89e3175.js”" 或title="代理池网页管理界面"

Warp+非常好用，速度快，又免费（名义上的收费，但事实上的免费），但是源IP默认为相邻的地区，在使用一些应用时会受目标站点的限制，比如访问: ChatGPT、Netflix等站点，现有终于有大神解决了该问题。

下载

项目源代码：

https://github.com/bepass-org/warp-plus

可执行文件下载地址：
warp-plus

使用

warp -b 0.0.0.0: 本地端口号 -e 优选 ip: 端口号 -k g8lG9B50-Ge346l2I-5FeYv182 -country 国家代码 -cfon
  • 本地端口号：本机Socks代理端口号
  • 优选 ip: 端口号：使用warp plus的优选Endpoint IP及端口，通过优选工具选取最优IP及端口
  • warp plus密钥：填写Warp+ key，参考get warp plus key

  • 国家代码：填写你想设定的国家地区代码，如下：

    Austria (AT)
Belgium (BE)
Bulgaria (BG)
Brazil (BR)
Canada (CA)
Switzerland (CH)
Czech Republic (CZ)
Germany (DE)
Denmark (DK)
Estonia (EE)
Spain (ES)
Finland (FI)
France (FR)
United Kingdom (GB)
Hungary (HU)
Ireland (IE)
India (IN)
Italy (IT)
Japan (JP)
Latvia (LV)
Netherlands (NL)
Norway (NO)
Poland (PL)
Romania (RO)
Serbia (RS)
Sweden (SE)
Singapore (SG)
Slovakia (SK)
Ukraine (UA)
United States (US)

    应用示例：

    warp -b 0.0.0.0:12345 -e 162.159.192.100:987 -k g8lG9B50-Ge346l2I-5FeYv182 -country JP -cfon

    执行后，出现如下提示，说明建立成功：
    2024-04-15T06:13:54.png

保持该窗口不关闭，用代理软件或者浏览器访问本地socks代理127.0.0.1:12345即可上网，并实现IP固定为日本地区。
