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,并使它们一起工作,这一切都很好,直到我想在另一个脚本中使用main.py脚本中创建的对象。
我不想在我的非主脚本中创建新对象。我想使用在main.py中用不同脚本创建的现有对象。
我通过GPIO上的串口连接到GSM调制解调器,所以我可以使用AT命令来"通话"它。我有powerOn.py类(我不会在这里发布)我有一些引脚设置,serial.py脚本,我有一些方法,允许我通过serialClass和我最新的丑陋孩子串口通信gsmSMS.py脚本(我目前正在处理它)我希望有一些方法来发送sys,openSMS,listSMSs,delteSpecificSMS,deleteAllSMS等。在这些方法中我需要来自serialConnection的send()和receive()但是没有在这个sript中创建一个新对象。
但问题出在这里:
我的main.py脚本(好吧......部分内容):
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,但由于它正常工作,我决定不打算编写代码。
这是我的serial.py
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
同样,不是整个代码。
我的sms.py脚本: class 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:&#39;短信&#39;对象没有属性状态
这意味着程序&#34;认为&#34; &#34; self.state&#34;在serialConnection.send()for python isnt serialConnectionObject.state但是smsObject.state它找不到它,因为没有人。对?但是我怎样才能让它发挥作用呢?
和 问题2: 为什么我必须将self置于send()中?或者我不应该?现在,当我写它时,我认为它可能会导致问题(因为我有点将自己从短信传递到serialConnection)!但是我这样做是因为在我这样做之前: serialConnectionClass.send(命令),我有这个: 错误:send()缺少1个必需的位置参数:&#39; message&#39; 它有点像send()需要的不仅仅是一个参数。但是由于send(self,command)导致问题而send(命令)不起作用,我该怎么做呢? :d

在班级sms
中,您拥有(并提供)参数serialGSMclass
。但你没有对他做任何事。你应该做那样的事情
def __init__(self, serialGSMclass):
self.setATE0() #AND OFC PROBLEM "GOES" HERE
self.setSmsMessageFormat()
self.setPrefferedSmsMessageStorage()
self.serialGSMclass = serialGSMclass
def setATE0(self):
command = "ATE0"
self.serialGSMclass.send(self, command) #AND HERE
self.serialGSMclass.receive(self, False, True, False) #QUESTION 2!
if self.serialGSMclass.responseState=="COMPLETE_OK":
print("Set to ATE0")
else:
print("ERROR: Did not set ATE0!!!")
2:在类方法中,必须将self
作为第一个参数来使用类实例的变量,方法,....如果没有self
,您可以在方法定义上方写@staticmethod
。但是你不能再使用类变量和方法了。
示例:
class A:
def __init__(self, a):
self.a = a
def print_a(self):
print(self.a)
@staticmethod
def print_a_static():
print(self.a)
@staticmethod
def print_a_static_2():
print(a)
a_instance = A(2) # a_instance is a instance of the class A now and has a variable a=2
a_instance.print_a() # print the value of a: 2
a_instance.print_a_static() # Exception: unknown self
a_instance.print_a_static_2() # Exception: unknown a

Soebody发布了一个有效的答案,但它被删除了......对不起,我不记得你的昵称了。 我缺少的是sms.py init ()脚本:
def __init__(self, serialConnection):
if not serialConnection:
raise Exception ("invalid serial connection")
self.serialConnection = serialConnection
然后它工作正常。
哦,抱歉。是你吗,julivico?
