Python subprocess 使用(一)

本文主要讲下 subprocess 的简单使用.

1: 通过subprocess 获取设备信息

import subprocess
def get_android_device_info():
    # 使用adb命令获取设备信息
    result = subprocess.run(['adb', 'devices', '-l'], capture_output=True, text=True)
    output = result.stdout.strip()

    # 解析设备信息
    devices = []
    lines = output.split('\n')
    for line in lines[1:]:
        if 'device' in line:
            device_info = line.split()
            device = {
                'serial': device_info[0],
                'model': device_info[4],
                'device': device_info[5],
                'product': device_info[3],
                'transport_id': device_info[6]
            }
            devices.append(device)

    return devices

# 调用函数获取设备信息
devices = get_android_device_info()
for device in devices:
    print('Serial:', device['serial'])
    print('Model:', device['model'])
    print('Device:', device['device'])
    print('Product:', device['product'])
    print('Transport ID:', device['transport_id'])
    print('--')

具体的adb 执行结果如下:

List of devices attached
6b4a96b2               device usb:1-1 product:LeMax2_WW model:LEX820 device:le_x2 transport_id:43

2: 通过subprocess 获取屏幕分辨率

def get_device_physical():
    command = 'adb shell wm size'
    result = subprocess.check_output(command.split()).decode().strip()
    resolution = result.split()[-1]
    return resolution

print('设备分辨率：' + str(get_device_physical()))

3: 获取设备系统日志

def capture_android_log():
    # 使用adb命令获取Android系统日志
    command = "adb logcat"
    process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

    # 读取日志输出
    while True:
        line = process.stdout.readline().decode("utf-8")
        if line:
            print(line.strip())
        else:
            break


# 调用函数抓取Android系统日志
capture_android_log()
