本文主要介紹使用Python調(diào)用ADB命令實(shí)現(xiàn)實(shí)時(shí)監(jiān)控logcat關(guān)鍵字的功能
采用多進(jìn)程,可同時(shí)監(jiān)控多個(gè)設(shè)備,監(jiān)控多個(gè)關(guān)鍵字。
需要配置ADB環(huán)境,具體配置就不多介紹,隨便搜一下一大把,直接上代碼
通過一個(gè)全局變量控制開啟和關(guān)閉監(jiān)控功能, INSTRUCTION 用于根據(jù)指令獲取對應(yīng)的方法名
import os, threading, datetime # 獲取當(dāng)前文件所在目錄,拼接出LOG路徑 LOG_PATH = os.path.join(os.path.dirname(os.path.abspath(__file__)), "log") # 配置需要監(jiān)控的關(guān)鍵字 KEYWORDS = ["ANR ", "NullPointerException", "CRASH", "Force Closed"] # 控制開啟和關(guān)閉 STOP_LOGCAT = True # 指令對應(yīng)具體操作 INSTRUCTION = { "1": "filter_keywords", "2": "stop_filter_keywords", "3": "exit" } def filter_keywords(): global STOP_LOGCAT STOP_LOGCAT = False devices = get_devices() # 先獲取所有連接的設(shè)備 print("開始監(jiān)控關(guān)鍵字") for device in devices: t = threading.Thread(target=filter_keyword, args=(device,)) t.start() def stop_filter_keywords(): global STOP_LOGCAT if STOP_LOGCAT: print("沒有正在執(zhí)行的任務(wù)n") else: STOP_LOGCAT = True print("正在停止關(guān)鍵字監(jiān)控n")
監(jiān)控關(guān)鍵字主函數(shù),
def filter_keyword(device): print("設(shè)備%s關(guān)鍵字監(jiān)控已開啟" % str(device)) sub = logcat(device) with sub: for line in sub.stdout: # 子進(jìn)程會(huì)持續(xù)輸出日志,對子進(jìn)程對象.stdout進(jìn)行循環(huán)讀取 for key in KEYWORDS: if line.decode("utf-8").find(key) != -1: # stdout輸出為字節(jié)類型,需要轉(zhuǎn)碼 message = "設(shè)備:%s 檢測到:%sn" % (device, key)# 設(shè)備:192.168.56.104:5555 檢測到:ANR path = get_log_path("bugreport") # 根據(jù)時(shí)間創(chuàng)建文件夾 bugreport(device, path)# 拉取完整日志壓縮包到創(chuàng)建的文件夾內(nèi) send_message(message) # 這里可以換成自己要做的事情,比如發(fā)送郵件或釘釘通知 if STOP_LOGCAT: break print("設(shè)備%s關(guān)鍵字監(jiān)控已停止" % str(device)) sub.kill()
通過 subprocess.Popen 創(chuàng)建進(jìn)程執(zhí)行命令,持續(xù)輸出日志到 stdout
# logcat持續(xù)輸出日志 def logcat(device): command = "adb -s " + str(device) + " logcat -v time" sub = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) return sub
獲取所有已連接設(shè)備的方法,執(zhí)行"adb devices"后輸出如下,通過對命令執(zhí)行拿到的字符串切割獲取所有設(shè)備號以列表方式存儲
# 獲取所有device def get_devices(): command = "adb devices" res = os.popen(command).read() devices = [] res = res.split("n") for i in res: if i.endswith("device"): devices.append(i.split('t')[0]) return devices
# 打包下載所有日志到當(dāng)前目錄 def bugreport(device, path): os.chdir(path)# bugreport會(huì)下載日志到當(dāng)前文件夾,所以需要先切換到已經(jīng)創(chuàng)建的目錄 command = "adb -s " + str(device) + " bugreport" subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, bufsize=-1) print("設(shè)備:%s 日志路徑:%s" % (str(device), path))
以 當(dāng)前文件所在目錄/年/月/日 格式獲取日志路徑,如果不存在自動(dòng)創(chuàng)建
# 獲取日志存放路徑,如果不存在則按日期創(chuàng)建 def get_log_path(tag): year = datetime.datetime.now().strftime('%Y') month = datetime.datetime.now().strftime('%m') day = datetime.datetime.now().strftime('%d') path = os.path.join(LOG_PATH, tag, year, month, day) if not os.path.exists(path): os.makedirs(path) return path
main函數(shù),循環(huán)接收指令,根據(jù)接收的指令拿到方法名,并通過eval()方法執(zhí)行。
def main(): while True: print("-" * 100) print("1:開啟關(guān)鍵字監(jiān)控n2:停止關(guān)鍵字監(jiān)控n3:退出") print("-" * 100) instruction = str(input("nn請輸入要進(jìn)行的操作號:n")) print("-" * 100) while instruction not in INSTRUCTION.keys(): instruction = str(input("nn輸入無效,請重新輸入:")) if int(instruction) == 9: exit() # TODO 退出前需要判斷是否有正在執(zhí)行的monkey任務(wù)和關(guān)鍵字監(jiān)控任務(wù) eval(INSTRUCTION[str(instruction)] + "()") if __name__ == '__main__': main()
代碼分段之后有點(diǎn)凌亂,看不明白可以把代碼復(fù)制到一個(gè)文件里捋一下就明白了
