如何持续监控outlook中的新邮件和python中特定文件夹的未读邮件

Question

我想检查特定的发件人电子邮件并在它到达的任何地方自动处理它

但是，在某些情况下，我的 Outlook 可能会重新启动，这意味着当我收到来自发件人的邮件并标记为未读时

为了持续监控特定主题的新邮件，我找到了以下代码

import win32com.client
import pythoncom
import re

class Handler_Class(object):
  def OnNewMailEx(self, receivedItemsIDs):
    # RecrivedItemIDs is a collection of mail IDs separated by a ",".
    # You know, sometimes more than 1 mail is received at the same moment.
    for ID in receivedItemsIDs.split(","):
        mail = outlook.Session.GetItemFromID(ID)
        subject = mail.Subject
    print subject   
        try: 
            command = re.search(r"%(.*?)%", subject).group(1)

            print command # Or whatever code you wish to execute.
        except:
            pass


outlook = win32com.client.DispatchWithEvents("Outlook.Application",Handler_Class)

#and then an infinit loop that waits from events.
pythoncom.PumpMessages() 

即使我想通过所有未读邮件来检查发件人的邮件是否已经到达并处理它（如果找到）

是否有任何功能可以检查未读邮件以添加到 handler_class 中

或者让我知道任何替代程序

因此，如果您每次重新启动 Outlook 时都重新启动 Python 脚本，那么将这些行添加到您的代码中以检查收件箱中的未读电子邮件：

ol = win32com.client.Dispatch( "Outlook.Application")
inbox = ol.GetNamespace("MAPI").GetDefaultFolder(6)
for message in inbox.Items:
    if message.UnRead == True:
        print message.Subject #or whatever command you want to do

将此代码放在代码中outlook 的定义之前

对我来说，您发布的代码在我关闭 Outlook 之前运行良好，然后即使我重新打开它，在收到新消息时我什么也得不到（请参阅我的一个 cmets）。我猜想用pythoncom.PumpMessages() 关闭Outlook“取消链接”的事实。无论如何，我会在 Handler_Class 类中检查未读电子邮件并重新启动监控，以防你重新启动 Outlook。

import win32com.client
import ctypes # for the VM_QUIT to stop PumpMessage()
import pythoncom
import re
import time
import psutil

class Handler_Class(object):

    def __init__(self):
        # First action to do when using the class in the DispatchWithEvents     
        inbox = self.Application.GetNamespace("MAPI").GetDefaultFolder(6)
        messages = inbox.Items
        # Check for unread emails when starting the event
        for message in messages:
            if message.UnRead:
                print message.Subject # Or whatever code you wish to execute.

    def OnQuit(self):
        # To stop PumpMessages() when Outlook Quit
        # Note: Not sure it works when disconnecting!!
        ctypes.windll.user32.PostQuitMessage(0)

    def OnNewMailEx(self, receivedItemsIDs):
    # RecrivedItemIDs is a collection of mail IDs separated by a ",".
    # You know, sometimes more than 1 mail is received at the same moment.
        for ID in receivedItemsIDs.split(","):
            mail = self.Session.GetItemFromID(ID)
            subject = mail.Subject
            print subject   
            try: 
                command = re.search(r"%(.*?)%", subject).group(1)
                print command # Or whatever code you wish to execute.
            except:
                pass

# Function to check if outlook is open
def check_outlook_open ():
    list_process = []
    for pid in psutil.pids():
        p = psutil.Process(pid)
        # Append to the list of process
        list_process.append(p.name())
    # If outlook open then return True
    if 'OUTLOOK.EXE' in list_process:
        return True
    else:
        return False

# Loop 
while True:
    try:
        outlook_open = check_outlook_open()
    except: 
        outlook_open = False
    # If outlook opened then it will start the DispatchWithEvents
    if outlook_open == True:
        outlook = win32com.client.DispatchWithEvents("Outlook.Application", Handler_Class)
        pythoncom.PumpMessages()
    # To not check all the time (should increase 10 depending on your needs)
    time.sleep(10)

不确定这是不是最好的方法，但它似乎可以按照您寻找的方式工作。

不要从 python 监控 Outlook，而是尝试为该电子邮件设置 Outlook 规则，然后通过 vba 启动 python 脚本。

这是从 VBA 启动 python 脚本的代码。

注意：以下代码取自here。

Sub UruchomBata(MyMail As MailItem)
  Dim Ret_Val
    Dim args As String

    args = "c:\new.py"
    Ret_Val = Shell("C:\python27\python.exe" & " " & args, vbNormalFocus) 
  End Sub

这行下面是 Python 脚本，供感兴趣的人使用。这是 当前设置为控制 com1 串行端口上的 DTR 引脚。这 以下将需要保存为 yourname.py 文件

import serial
from time import sleep


conn = serial.Serial('com1',
                     baudrate=9600,
                     bytesize=serial.EIGHTBITS,
                     parity=serial.PARITY_NONE,
                     stopbits=serial.STOPBITS_ONE,
                     timeout=1,
                     xonxoff=0,
                     rtscts=0
                     )
# Wake Modem

conn.setDTR(True)
sleep(3)
conn.setDTR(False)
sleep(1)


conn.close()


# Start talking

try:
    while True:
        conn.write('AT'+chr(13));
        print conn.readline() # readlines() will probably never return.
finally:
    conn.close()
