This time I will bring you how to use adb shellnode.jsto realize Douyin’s automatic grabbing of red envelopes, and use adb shell node.js to realize Douyin’s automatic grabbing of red envelopes.NotesWhat are they? The following is a practical case. Let’s take a look.
The logic is very simple. After the Douyinvideois played, if it is a red envelope video, the red envelope will pop up. Our simulation logic is as follows:
Click the center of the screen. If there is a red envelope, open the red envelope. If there is no red envelope, the video will be paused.
Click the return button. If there is a red envelope, close the red envelope interface. If there is no red envelope, pressto exit(actually, it does not exit).
#Swipe up to go to the next video.
Click, return, and swipe up, just three steps. It works regardless of whether there is a red envelope or not, as long as you calculate the time.
Code
The following is a piece ofnode.jscode:
touch.js
var process = require('child_process'); function exec(shell) { process.exec(shell,function (error, stdout, stderr) { if (error !== null) { console.log('exec error: ' + error); } }); } function click() { console.log('click') exec(`adb shell input tap 400 600`) setTimeout(back, 1000) } function swipe() { console.log('swipe') exec(`adb shell input swipe 400 800 400 0 500`) setTimeout(click, 20000) } function back() { console.log('back') exec(`adb shell input keyevent 4`) setTimeout(swipe, 1000) } swipe()
Turn on the developer mode of the phone and start USBdebugging. If it is Xiaomi, please also turn on USB debugging (Securitysettings). Connect your phone and open the main interface of Douyin. Save this js locally and execute it using node.
$ node touch.js
If you find that Douyin slides up every 20 seconds, it means it is successful~
Principle
Articles similar to using adb shell to operate mobile phones also include jump operations, etc. The principle is explained below.
child_process.exec(command[, options][, callback])
The function of this method is to spawn a shell, then execute the command in the shell, and buffer any generated output. For details, please refer to the reference document. In fact, it is equivalent to executing scripts and shell commands. We use it to execute adb shell commands.
adb shell
adb is a development tool for connecting computers to mobile phones. All computer operations on mobile phones are actually completed by adb, including various mobile phone assistants that help you install APPs. PS: I have been working on mobile phones for so long, and I just discovered this interesting function today... Sigh...
adb shell can install apk, view mobile phone information, operate mobile phone files, simulate click behavior and other functions, it is very powerful. Our main purpose here is to simulate the click behavior of adb shell input. The functions are listed below:
// 输入文本 content $ adb shell input text “hello” // 点击返回按钮 keynumber $ adb shell input keyevent 4 // 点击屏幕某个点 x y $ adb shell input tap 400 400 // 滑动 x1 y1 x2 y2 time $ adb shell input swipe 400 800 400 0 500 // 下面三个不太清楚，再研究 $ adb shell input press $ adb shell input roll $ adb shell input tmode
For more key corresponding values, you can see the corresponding values ofAndroidkeyevent. Through these commands, we can perform some simple operations on the mobile phone~
at last
This is actually a very simple logic, but it gave me a lot of inspiration. If there are any simple operations in the future, I can use adb and node to repeat them~ Finally, I will complain: There are really few red envelopes on Douyin. I spent 3 hours browsing yesterday. It’s just a few cents, which is not enough for the electricity bill. Just treat it as entertainment~
PS: The following introduces the corresponding values of Android keyevent
Each value in Android keyevent can be used when using adb shell input.
KEYCODE_UNKNOWN=0; KEYCODE_SOFT_LEFT=1; KEYCODE_SOFT_RIGHT=2; KEYCODE_HOME=3; KEYCODE_BACK=4; KEYCODE_CALL=5; KEYCODE_ENDCALL=6; KEYCODE_0=7; KEYCODE_1=8; KEYCODE_2=9; KEYCODE_3=10; KEYCODE_4=11; KEYCODE_5=12; KEYCODE_6=13; KEYCODE_7=14; KEYCODE_8=15; KEYCODE_9=16; KEYCODE_STAR=17; KEYCODE_POUND=18; KEYCODE_DPAD_UP=19; KEYCODE_DPAD_DOWN=20; KEYCODE_DPAD_LEFT=21; KEYCODE_DPAD_RIGHT=22; KEYCODE_DPAD_CENTER=23; KEYCODE_VOLUME_UP=24; KEYCODE_VOLUME_DOWN=25; KEYCODE_POWER=26; KEYCODE_CAMERA=27; KEYCODE_CLEAR=28; KEYCODE_A=29; KEYCODE_B=30; KEYCODE_C=31; KEYCODE_D=32; KEYCODE_E=33; KEYCODE_F=34; KEYCODE_G=35; KEYCODE_H=36; KEYCODE_I=37; KEYCODE_J=38; KEYCODE_K=39; KEYCODE_L=40; KEYCODE_M=41; KEYCODE_N=42; KEYCODE_O=43; KEYCODE_P=44; KEYCODE_Q=45; KEYCODE_R=46; KEYCODE_S=47; KEYCODE_T=48; KEYCODE_U=49; KEYCODE_V=50; KEYCODE_W=51; KEYCODE_X=52; KEYCODE_Y=53; KEYCODE_Z=54; KEYCODE_COMMA=55; KEYCODE_PERIOD=56; KEYCODE_ALT_LEFT=57; KEYCODE_ALT_RIGHT=58; KEYCODE_SHIFT_LEFT=59; KEYCODE_SHIFT_RIGHT=60; KEYCODE_TAB=61; KEYCODE_SPACE=62; KEYCODE_SYM=63; KEYCODE_EXPLORER=64; KEYCODE_ENVELOPE=65; KEYCODE_ENTER=66; KEYCODE_DEL=67; KEYCODE_GRAVE=68; KEYCODE_MINUS=69; KEYCODE_EQUALS=70; KEYCODE_LEFT_BRACKET=71; KEYCODE_RIGHT_BRACKET=72; KEYCODE_BACKSLASH=73; KEYCODE_SEMICOLON=74; KEYCODE_APOSTROPHE=75; KEYCODE_SLASH=76; KEYCODE_AT=77; KEYCODE_NUM=78; KEYCODE_HEADSETHOOK=79; KEYCODE_FOCUS=80;//*Camera*focus KEYCODE_PLUS=81; KEYCODE_MENU=82; KEYCODE_NOTIFICATION=83; KEYCODE_SEARCH=84; KEYCODE_MEDIA_PLAY_PAUSE=85; KEYCODE_MEDIA_STOP=86; KEYCODE_MEDIA_NEXT=87; KEYCODE_MEDIA_PREVIOUS=88; KEYCODE_MEDIA_REWIND=89; KEYCODE_MEDIA_FAST_FORWARD=90; KEYCODE_MUTE=91;
Okay, that’s all.
