Hourly Reminder

忙起來的時候不知不覺時間就過去了,而久坐對健康絕對不是什麼好事。那麼就產生了一個需求,提醒我時間的流逝。Android上有個不錯的開源應用Hourly Reminder,但是我是在工作的時候才需要提醒,所以最好是桌面彈窗。簡單搜索發現Fedora預裝的notify-send命令就能很好的實現toast效果,搭配crontab就能滿足需求了。

crontab -e
#單行Hourly Reminder簡潔版
0 9-18 * * 1-5 notify-send -t 6000 '整點咯' 'It is 🕛 time.'
#Hourly Reminder python 豪華版

import time,datetime,subprocess,random

ts = int(time.time())
hour = datetime.datetime.fromtimestamp(ts).strftime('%H')
title = "現在時刻"+hour+"點整"
emojiList=['🍏','🍎','🍐','🍊','🍋','🍌','🍉','🍇','🍓','🍈','🍒','🍑','🍍','🥭','🥥','🥝','🍅','🍆','🥑','🥒','🥬','🌶','🌽','🥕','🥔','🍠','🥐','🍞','🥖','🥯','🧀','🥚','🍳','🥞','🥓','🍗','🍖','🌭','🍔','🍟','🍕','🥙','🌮','🌯','🥗','🥘','🍝','🍜','🍲','🍛','🍣','🍱','🍤','🍘','🍥','🥮','🍢','🍡','🍧','🍨','🍦','🍰','🎂','🍮','🍭','🍬','🍫','🍿','🧂','🍩','🍪','🌰','🥜','🍯','🥛','🍼','☕️','🍵','🥤','🍶','🍺','🍻','🥂','🍷','🥃','🍸','🍹','🍾']
content = '\r        '+random.choice(emojiList)+'\r'
subprocess.check_call(['notify-send','-t','6000',title,content])

幹掉QQProtect.exe

本文使用python3搭配windows的定時任務來實現正常使用TIM而不運行QQProtect.exe的功能。之所以沒有用bat是因為bat會彈出黑色命令行窗口,而使用pythonw則不會彈窗,體驗較好。方法參考自知乎如何禁用QPCore service启动项?

#file:killQQP.pyw
#杀死QQProtect.exe:killQQP.pyw 1
#启动TIM时杀死QQProtect.exe:killQQP.pyw 2

import os,time,sys

def killProgress(targetProgress):
    if targetProgress in os.popen('tasklist /FI \"IMAGENAME eq '+targetProgress+'\"').read():
        os.system('TASKKILL /F /IM '+targetProgress)

progressToBeKill = "QQProtect.exe"
progressToBeLaunch = "TIM.exe"
targetProgressFile = 'E:\\\"Program Files (x86)\"\\Tencent\\TIM\Bin\\QQScLauncher.exe' 
  
if str(sys.argv[1]) == "1":
    killProgress(progressToBeKill)
elif str(sys.argv[1]) == "2":
    count = 0
    time.sleep(5)
    os.system(targetProgressFile)
    time.sleep(2)
    while count < 5:
        killProgress(progressToBeKill)
        time.sleep(10)
        count = count + 1
        
else:
    killProgress(progressToBeKill)

然後在開始菜單運行taskschd.msc,新建定時任務。第一個定時任務:常規選項卡勾選“使用最高權限運行”;觸發器選項卡選擇“登錄時”;操作選項卡,程序或腳本填pythonw的位置,比如我的是C:\Users\42\AppData\Local\Programs\Python\Python35\pythonw.exe,添加參數則填寫上面腳本所在位置加參數,如E:\code\killQQP.pyw 1,保存。第二個定時任務:常規選項卡勾選“使用最高權限運行”;觸發器選項卡選擇“發生事件時”,然後日誌選“應用程序”,源填入QPCore,時間ID填入0;操作選項卡,程序或腳本填pythonw的位置,我的還是C:\Users\42\AppData\Local\Programs\Python\Python35\pythonw.exe,添加參數填寫腳本所在位置加參數,如E:\code\killQQP.pyw 2,保存即可。QQ用戶需要修改targetProgressFile為QQ的啟動文件,可以通過在QQ啟動快捷方式上右鍵查看詳情取得。

使用Termux搭建假wifi熱點

注:本文旨在學習研究wifi熱點相關知識,請勿用於任何違反道德之事。

需要一台Root過的Android(系統版本不低於5.0)手機,安裝好Termux和python。實現Captive Portal需要兩部分,請求重定向和授權頁面。重定向的實現有多種,這裡既然是假熱點,所以使用最簡單的iptables重定向dns。授權頁面則直接採用jczic/MicroWebSrv實現的網頁服務器。把MicroWebSrv解壓到~/scripts/MicroWeb,然後新建如下文件

#~/scripts/MicroWeb/forward.sh
remove127(){
  /system/bin/iptables -t nat -D PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.43.1:8000&&/system/bin/iptables -t nat -D PREROUTING -p tcp --dport 443 -j DNAT --to-destination 192.168.43.1:8000
}
add127(){
  /system/bin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.43.1:8000&&/system/bin/iptables -t nat -I PREROUTING -p tcp --dport 443 -j DNAT --to-destination 192.168.43.1:8000
}
if [[ $1 = "1" ]]; then
  echo "start"       
  add127
elif [[ $1 = "0" ]]; then
  echo "stop"
  remove127
fi
#~/scripts/MicroWeb/web.py
from microWebSrv import MicroWebSrv
mws = MicroWebSrv(port=8000,bindIP='0.0.0.0',webPath="/data/data/com.termux/files/home/scripts/MicroWeb/www")
mws.SetNotFoundPageUrl("http://192.168.43.1:8000/hotspot-detect.html")
mws.Start(False)

上面文件唯一需要修改的地方是你手機的wifi網關,可以在打開手機熱點後通過ip addr命令查看,我的是wlan0網卡,網關是192.168.43.1。

#iptable需要root權限
su
./forward.sh 1
#然后新开一个session運行web server
python web.py
#這時其他手機連上此熱點,即會彈出自定義頁面hotspot-detect.html。

python守護tomcat

下面腳本實現定時檢測tomcat是否還活着,如果死了就啟動它,如果活太久了(24小時)就殺掉再啟動。

在win平台處理自定義協議

在IOS上,Safari可以通過網頁跳轉到snssdk141://detail?id=123456789拉起指定應用並展示內容,但是Safari並不顯示此鏈接。通過添加註冊表和Python可以實現在PC上獲取到這個自定義的協議鏈接。

首先添加註冊表來監聽這種協議,保存下面文本為p.reg運行即可導入:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\snssdk141]
@="\"URL:My Protocol\""
"URL Protocol"=""

[HKEY_CLASSES_ROOT\snssdk141\shell]

[HKEY_CLASSES_ROOT\snssdk141\shell\open]

[HKEY_CLASSES_ROOT\snssdk141\shell\open\command]
@="\"C:\\Users\\42\\AppData\\Local\\Programs\\Python\\Python35\\python.exe\" \"F:\\scripts\\tt.py\" %1"


然後新建F:\\scripts\tt.py內容如下,把鏈接複製到剪切版:

###!C:\Users\42\AppData\Local\Programs\Python\Python35
# coding:utf-8
#snssdk141://detail/?id=123456789
import sys,pyperclip

if __name__ == '__main__':    
    if str(sys.argv[1]) :
        pyperclip.copy(sys.argv[1])
    else:
        pyperclip.copy('fail')

在火狐打開會自動跳轉的網頁,就會彈出選擇框,選擇python運行後就在剪切板里獲取到了snssdk141://detail/?id=123456789。

彎路:火狐並不能添加處理自定義協議的設置。Chrome 58版本在網絡面板可以看到snssdk141://detail/?id=123456789這個鏈接,但是新版Chrome、Chronium和Firefox ESR均無法顯示出網頁中試圖訪問自定義鏈接的請求。requests的作者新開發了個工具叫requests-html,可以支持js和用chrome渲染頁面,及跟蹤網頁跳轉,但是文檔似乎還不完整。

Termux Python3.6安裝paramiko

之前寫過一個python腳本通過paramiko使用SSH鏈接越獄後的iPhone執行一些安裝軟件或重啟SpringBoard之類的操作。後來遇到Termux覺得安卓手機也可以試試,不試不知道,一試坑不少,好在最後還是裝好了。

#首先安裝系統的依賴
apt install libffi-dev clang libsodium libsodium-dev openssl-dev libcrypt-dev python-dev
#然後安裝pynacl,直接pip裝會報錯,指定使用系統的sodium庫即可
SODIUM_INSTALL=system
pip install pynacl
#最後再安裝paramiko和python-nmap
pip install paramiko python-nmap
