python编写adb截图工具的实现源码

一、 功能

android端或者android终端的远程截图至本地电脑中

二、使用说明

1.adb截图工具可用于android手机及android终端
2.使用数据线连接前提：电脑与android终端/手机已连接
android终端/手机已打开开发者模式
3.生成的图片格式为png

三、实现

1.初始源码

        if filepath==none:
            adb_devices(n,lines)
        else:  
            adb_devices(n,lines,filepath)

#输入ip
def ip_info():
    ippath=input("请输入ip：（不输入enter跳过默认使用数据线连接）\n")
    if len(ippath)>0:
        try:
            cnd='adb connect '+ippath
            os.system(cnd)
            return ippath
        except:
            print("adb调试模式为usb，需要切换到无线调试模式\n")
            print("切换方法:\n第一步：android设备开启usb调试，并且通过usb线连接到电脑\n第二步：在终端执行以下命令”adb tcpip 5555“\n第三步：在终端执行以下命令”adb connect ip“。此时拔出usb线，应该就可以adb通过wifi调试设备\n")
            return ip_info()
if  __name__ == '__main__':
    ippath=ip_info()
    filepath=input("请输入保存地址:(不输入enter跳过，默认保存至d:\png\)\n")
    #查询当前连接的设备
    r=os.popen("adb devices")
    lines=r.readlines()
    lines=lines[1:-1]
    n=len(lines)
    ip_add=0
    if ippath!=none:
        for i in lines:
            if ippath in i:
                ip_add=i.split("\t")[0]
    if len(filepath)>0:
        if ":\\" in filepath:
            if ip_add!=0:
                adb_devices(n,ip_add,filepath)
            else:
                adb_devices(n,lines,filepath)
        else:
            print("地址输入非法，使用默认地址\n")
            if ip_add!=0:
                adb_devices(n,ip_add)
            else:
                adb_devices(n,lines)
    else:
        if ip_add!=0:
            adb_devices(n,ip_add) 
        else:
            adb_devices(n,lines) 

2.优化：增加ip连接断开重连处理

在输入ip函数ip_info()增加ip连接判断，将os.system替换成os.popen函数执行cmd命令：

r=os.popen(cnd)
#读取执行结果
lines=r.readlines()[0]
if 'unable' in lines:
    print("连接失败\n")
    return ip_info()
else:
    return ippath

1. os.system函数无法获取执行结果，只能获取执行成功或失败的结果，成功返回0，失败返回1，且会执行的结果打印在终端上，相当于调起dos执行命令
2. os.popen函数可获取执行的结果内容，但获取的结果要进行readlines读取，执行的结果不会打印在终端上

在输入ip函数ip_info()增加ip连接判断，将os.system替换成os.popen函数执行cmd命令：

a=os.system(cmd_screencap)
if a==0:
   os.system(cmd_pull)
   os.system(cmd_delete)
else:
   if ":5555" in devices:
            print("连接断开，请重新连接\n")
            ippath=ip_info()
            if ippath==none:
                ippath=ip_info()
            else:
                device=ippath+":5555"
                adb_info(device,filepath)
        else:
            print("设备连接断开，请更换设备\n")
            device=change_devices()
            adb_info(device,filepath)
