嗨,伙计们。 我有几个脚本包含不同的类,我有主脚本,我使用这些类,使他们一起工作,这一切都做得很好,直到我想在另一个脚本中使用main.py脚本中创建的对象
我不想在非主脚本中创建新对象。我想使用现有的对象,在main.py中以不同的脚本创建
我通过GPIO上的串行端口连接到GSM调制解调器,这样我就可以使用ATcommands与之“交谈”。我有powerOn.py类(我不想在这里发布),其中有一些pin设置,serial.py脚本,其中有一些方法允许我通过serialClass内的串行端口进行通信,还有我最新的丑陋的孩子gsmSMS.py脚本(我目前正在编写),其中我想有一些方法来发送sms、openSMS、listSMSs、delteSpecificSMS,deleteAllSMS等。在这些方法中,我需要从serialConnection发送()和接收(),但不需要在此sript中创建新对象
但问题是:
我的main.py脚本(嗯。。一部分):
def main():
try:
global running
running = True
global atCommandLineOn
atCommandLineOn = True
with ooGSM.RPiToGsmPins() as modemGSM:
with aGsmSerial.serialConnection() as serialGSM:
if modemGSM.czyWlaczany==True:
sms = aGsmSMS.sms(serialGSM) #THIS WHERE PROBLEM STARTS!!!!
else:
print("ERROR: Turn on the modem!!!")
if atCommandLineOn==True:
print("AT command line is ON.")
else:
print("AT command line is OFF.")
while running==True:
print("Write command:\n :: ", end="")
command = str(input())
menu(command, modemGSM, serialGSM)
time.sleep(0.5)
except OSError:
print("asdasdfsdff")
if __name__ == "__main__":
main()
魔法发生在menu()中,但由于它工作正常,我决定不压缩代码
这是我的连载
class serialConnection():
IDLE = 0; SENDING = 1; RECEIVING = 2;
UNKNOWN = 0; COMPLETE_OK = 1; COMPLETE_ERROR = 2; NOTCOMPLETE = 3; EMPTY = 4;
def __init__(self, devicePath="/dev/ttyAMA0", timeout=3):
self.STATE = ["IDLE", "SENDING", "RECEIVING"]
self.STATE_RESPONSE = ["UNKNOWN" ,"COMPLETE_OK", "COMPLETE_ERROR", "NOTCOMPLETE", "EMPTY"]
self.mySerial = serial.Serial(devicePath)
self.mySerial.timeout = timeout
self.state = self.STATE[serialConnection.IDLE]
def __enter__(self):
return self
def __exit__(self, type, value, traceback):
self.mySerial.flushInput()
self.mySerial.flushInput()
self.mySerial.close()
print("Serial connection closed")
def send(self, message, printWhatIsSent=True):
command = message + "\r"
if self.state==self.STATE[serialConnection.IDLE] and self.mySerial.isOpen(): #THIS IS WHERE PROGRAM STOPS
self.responseState=self.STATE_RESPONSE[serialConnection.UNKNOWN]
self.state = self.STATE[serialConnection.SENDING]
messageInBytes = self.str2byte(command)
self.mySerial.write(messageInBytes)
self.mySerial.flushOutput()
self.state = self.STATE[serialConnection.IDLE]
if printWhatIsSent==True:
print(">>>>> Command sent: " + message)
else:
print("!!!ERROR: Command did not send")
def str2byte(self, message):
return bytearray(message, "ascii")
def receive(self, saveResponseToFile=True, printResponseStatus=True, printResponse=True):
bytesToRead = self.mySerial.inWaiting()
responseReadyToSave = "saveResponseToFile=False"
if self.state==self.STATE[serialConnection.IDLE] and self.mySerial.isOpen():
self.state = self.STATE[serialConnection.RECEIVING]
while self.state==self.STATE[serialConnection.RECEIVING]:
modemResponse = ""
while self.mySerial.inWaiting() > 0:
responseInBytes = self.mySerial.read(bytesToRead)
modemResponse += self.byte2str(responseInBytes)
self.mySerial.flushInput()
self.state = self.STATE[serialConnection.IDLE]
if printResponse==True:
print("<<<<< received:")
print(modemResponse)
if self.lookForEndChars(modemResponse)==False:
self.isResponseEmpty(modemResponse)
if saveResponseToFile==True:
responseReadyToSave = self.makeResponseReadyToSave(modemResponse)
if printResponseStatus==True:
if self.responseState==self.STATE_RESPONSE[serialConnection.NOTCOMPLETE]:
print("INFO: End char is missing!!!")
print()
elif self.responseState==self.STATE_RESPONSE[serialConnection.EMPTY]:
print("INFO: Response is EMPTY!!!")
print()
elif self.responseState==self.STATE_RESPONSE[serialConnection.UNKNOWN]:
print("This one should never be printed!!!")
print()
print()
return responseReadyToSave
再说一遍,不是全部代码
还有我的sms.py脚本: 类sms():
def __init__(self, serialGSMclass):
self.setATE0() #AND OFC PROBLEM "GOES" HERE
self.setSmsMessageFormat()
self.setPrefferedSmsMessageStorage()
def setATE0(self):
command = "ATE0"
serialGSMclass.send(self, command) #AND HERE
serialGSMclass.receive(self, False, True, False) #QUESTION 2!
if serialGSMclass.responseState=="COMPLETE_OK":
print("Set to ATE0")
else:
print("ERROR: Did not set ATE0!!!")
错误:“sms”对象没有属性状态
这意味着程序“认为”python的serialConnection.send()中的“self.state”不是serialConnectionObject.state,而是smsObject.state,它找不到它,因为没有。对吗?但我怎样才能让它工作呢
以及 问题2: 为什么我要把self放进send()呢?或者我不应该?现在,当我写它的时候,我想它可能会导致这个问题(因为我有点把自己从sms传递到serialConnection)!但我这么做是因为在我这样做之前: serialConnectionClass.send(命令)我有: 错误:send()缺少1个必需的位置参数:“message” 有点像send()需要的不仅仅是一个参数。但是既然send(self,command)引起了问题,send(command)也不起作用,我该如何使它起作用呢D级
Soebody发布了一个有效的答案,但被删除了。。对不起,我不记得你的昵称了。 我缺少的是sms.pyinit()脚本:
然后它工作得很好
哦,对不起。是你吗,朱利维科
在类
sms
中有(并给出)一个参数serialGSMclass
。但你对他什么也没做。你应该这样做2:在类方法中,必须将
self
作为第一个参数来使用变量、方法。。。类实例的。如果没有self
,就必须在方法定义上方写@staticmethod
。但是你不能再使用类变量和方法了示例:
