【未解决】安卓游戏暗黑觉醒自动化：进入首页后就是首充充值弹框
期间，对于之前函数：
utils/common_utils.py
def multipleRetry(functionInfoDict, maxRetryNum=5, sleepInterval=0.1, isShowErrWhenFail=True):
"""
do something, retry mutiple time if fail
Args:
functionInfoDict (dict): function info dict contain functionCallback and [optional] functionParaDict
maxRetryNum (int): max retry number
sleepInterval (float): sleep time of each interval when fail
isShowErrWhenFail (bool): show error when fail if true
Returns:
bool
Raises:
"""
doSuccess = False
functionCallback = functionInfoDict["functionCallback"]
functionParaDict = functionInfoDict.get("functionParaDict", None)
curRetryNum = maxRetryNum
while curRetryNum > 0:
if functionParaDict:
doSuccess = functionCallback(**functionParaDict)
else:
doSuccess = functionCallback()
if doSuccess:
break
time.sleep(sleepInterval)
curRetryNum -= 1
if not doSuccess:
if isShowErrWhenFail:
functionName = str(functionCallback)
# '<bound method DevicesMethods.switchToAppStoreSearchTab of <src.AppCrawler.AppCrawler object at 0x1053abe80>>'
logging.error("Still fail after %d retry for %s", maxRetryNum, functionName)
return doSuccess具体调用举例：
isGotoPay = CommonUtils.multipleRetry({"functionCallback": self.isGotoPayPopupPage})有个缺点：
传入的函数，返回值必须是：单个的bool变量
而不支持：返回多个值的情况
希望：增加支持传入函数返回值是tuple或别的类型的变量的情况
至少此处是tuple，三个值，则第一个值要是bool
如果支持了这种返回多个值的tuple类型，最好还要：增加把完整的返回值返回给调用者
if functionParaDict: # doSuccess = functionCallback(**functionParaDict) respValue = functionCallback(**functionParaDict) else: # doSuccess = functionCallback() respValue = functionCallback() doSuccess = False if isinstance(respValue, bool): doSuccess = bool(respValue) elif isinstance(respValue, tuple): doSuccess = respValue first value
期间又遇到：对于tuple，不知道具体几个值，希望获取第一个值
如何写？
python get first element of tuple
好像就是支持 someTuple[0] 即可获取第一个值？
Tuples can be indexed just like lists.
就是的，可以像list一样去索引tuple
就像代码：
finalReturnValue = None
doSuccess = False
if isinstance(respValue, bool):
doSuccess = bool(respValue)
elif isinstance(respValue, tuple):
doSuccess = bool(respValue[0])
elif isinstance(respValue, list):
doSuccess = bool(respValue[0])
else:
Exception("multipleRetry: Not support type of return value: %s" % respValue)
if doSuccess:
if isRespFullRetValue:
finalReturnValue = respValue
else:
finalReturnValue = doSuccess
break去调试看看
调用：
def isGotoPayPopupPage_multipleRetry(self, isRespFullInfo=False):
"""鉴于 暗黑觉醒 的 首充弹框 的检测很不稳定，所以 增加此函数 多次尝试 以确保 当是首充页面时，的确能稳定的检测出的确是"""
respBoolOrTuple = CommonUtils.multipleRetry(
{
"functionCallback": self.isGotoPayPopupPage,
"functionParaDict": {
"isRespLocation": isRespFullInfo,
},
"isRespFullRetValue": isRespFullInfo,
}
)
return respBoolOrTuple然后根据此处的isRespFullInfo决定是：
返回单个bool，还会返回完整信息tuple（带坐标位置信息）
其调用：
isGotoPay = self.isGotoPayPopupPage_multipleRetry()
发现参数错误，调整为：
def isGotoPayPopupPage_multipleRetry(self, isRespLocation=False):
"""鉴于 暗黑觉醒 的 首充弹框 的检测很不稳定，所以 增加此函数 多次尝试 以确保 当是首充页面时，的确能稳定的检测出的确是"""
respBoolOrTuple = CommonUtils.multipleRetry(
{
"functionCallback": self.isGotoPayPopupPage,
"functionParaDict": {
"isRespLocation": isRespLocation,
},
"isRespFullRetValue": isRespLocation,
}
)
return respBoolOrTuple
isGotoPay, matchResult, imgPath = self.isGotoPayPopupPage_multipleRetry(isRespLocation=True)去调试看看
终于调试到：传入True的情况了
结果调用写错了，改为：
respBoolOrTuple = CommonUtils.multipleRetry(
functionInfoDict = {
"functionCallback": self.isGotoPayPopupPage,
"functionParaDict": {
"isRespLocation": isRespLocation,
},
},
isRespFullRetValue = isRespLocation,
)再去调试
也支持返回多个值的tuple类型了：
不过返回值要改：
# return doSuccess return finalReturnValue
即可。
【总结】
此处最终代码：
def multipleRetry(functionInfoDict, maxRetryNum=5, sleepInterval=0.1, isShowErrWhenFail=True, isRespFullRetValue=False):
"""do something, retry if single call failed, retry mutiple time until max retry number
Args:
functionInfoDict (dict): function info dict contain functionCallback and [optional] functionParaDict
maxRetryNum (int): max retry number
sleepInterval (float): sleep time (seconds) of each interval when fail
isShowErrWhenFail (bool): show error when fail if true
isRespFullRetValue (bool): whether return full return value of function call
Returns:
isRespFullRetValue=False: bool
isRespFullRetValue=True: bool / tuple/list/...
Raises:
