python實現adb shell之後的連續執行

import subprocess
#最基本的啟動程序方式類似cmd下執行: notepad.exe text.txt 命令
obj = subprocess.Popen(['notepad.exe','text.txt'], shell = True, stdin=subprocess.PIPE, stdout=subprocess.PIPE ,stderr=subprocess.PIPE)
print(obj.stderr.read().decode('gbk'))
#進入某個環境執行語句,需要依賴上次執行的狀態
obj = subprocess.Popen('python', shell = True, stdin=subprocess.PIPE, stdout=subprocess.PIPE ,stderr=subprocess.PIPE)
obj.stdin.write('print(6+7)'.encode('utf-8'))
info,err = obj.communicate()
print(info.decode('gbk'))
#進入某個環境執行語句(adb shell),注意shell內部命令需要帶\n,執行完後一定記得執行exit命令退出,否則會阻塞
obj = subprocess.Popen(['adb', 'shell'], shell = True, stdin= subprocess.PIPE, stdout=subprocess.PIPE ,stderr=subprocess.PIPE)
obj.stdin.write('ls\n'.encode('utf-8'))
obj.stdin.write('exit\n'.encode('utf-8')) #重點,一定要執行exit
info,err = obj.communicate()
print(info.decode('gbk'))
print(err.decode('gbk'))
#進入某個環境執行語句(adb shell),命令用列表方式全部列出
cmds = [
"cd data" ,
'cd data',
"ls",
"exit",#這是是非常關鍵的,退出
]
obj = subprocess.Popen("adb shell", shell= True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
info = obj.communicate(("\n".join(cmds) + "\n").encode('utf-8'));
for item in info:
if item:
print(item.decode('gbk'))
#當需要連續實時輸出資訊時,採用obj.stdout.readline方式讀取
import chardet
obj = subprocess.Popen("adb logcat", shell = True, stdin=subprocess.PIPE, stdout=subprocess.PIPE ,stderr=subprocess.PIPE)
for item in iter(obj.stdout.readline,'b'):
encode_type = chardet.detect(item)
if encode_type['encoding'] == 'utf-8':
print(item.decode('utf-8'))
else:
print(item.decode('gbk'))
