运行可执行文件以获取Outlook附件

Question

我编写了从 [email protected] 下载 Outlook 附件的 Python 代码将它们保存在special_folder中。当我在 Spyder 中运行它时效果很好，但是当我将其转换为可执行文件并运行它时，附件不会下载，但不会引发错误。我很困惑可能是什么问题。

import win32com.client as win
import datetime as dt


# Set up connection to outlook
outlook = win.Dispatch("Outlook.Application").GetNamespace("MAPI")

# Go to the inbox folder
inbox = outlook.GetDefaultFolder(6)

# Record the messages
messages = inbox.Items

# Get the first message
message = messages.GetLast()

# Record today's date
today = dt.date.today()

# Initialize email date to today
email_date = today

# Get yesterday's date
yesterday = today - dt.timedelta(days = 1)

# Initialize count at 0
count = 0

# Record the number of emails read
emails_read = 0

# Record the number of tries
tries = 0

# Record the number of excepts
excepts = 0

# Was the break reached?
break_reached = 0

# While the count is less than three
while count < 4:

  emails_read += 1
  
  try:

      # Record the email address
      email_address = message.SenderEmailAddress
      
      # Record the date when the message was sent
      email_date = message.senton
        
      # Convert the date to a dt.date object
      email_date = dt.date(year = email_date.year, month = email_date.month, day = email_date.day)
        
      # If the email is from [email protected] and the email was send yesterday... 
      if (email_address == '[email protected]') & ((email_date == yesterday)|(email_date == today)):
            
          # Record the attachment  
          attachments = message.Attachments
              
          # Get the first attachment
          attachment = attachments.Item(1)
              
          # Get the name of the attachment
          attachment_name = str(attachment)
              
          # Save the attachment in my ICE folder
          attachment.SaveASFile(particular_location + attachment_name)
              
          # Add 1 to the count
          count += 1
              
      # Move on to the next message
      message = messages.GetPrevious()
      
      tries += 1
       
  # ... when not possible...
  except:
        
      # ... move on to the next message            
      message = messages.GetPrevious()
      
      excepts += 1
          
    
  if (emails_read > 1e4)|(email_date == dt.date.today() - dt.timedelta(days = 2)):
      
      break_reached += 1
      
      break
  
# Create a log dictionary
log_dict = {'count':count, 'emails_read':emails_read, 'tries':tries, 'excepts':excepts, 
            'break_reached':break_reached, 'email_date':email_date.strftime("%m-%d-%y")}

   
# Record the hyperparameters from the cross-validation
with open(other_location + 'log.txt', 'w') as f: 
    
    # Look over the dictionary of best hyperparameters
    for key, value in log_dict.items(): 
        
        # Print key: value (space)
        f.write('%s:%s\n' % (key, value))

我已将日志添加到上面显示的代码中。日志中写道：

计数：0 emails_read：10001 尝试：0 例外：10001 Break_reached：1 email_date:03-30-22

所以，事实证明我总是在 try 情况下收到错误，并且它转到 except 。

有很多原因会导致您的代码无法将附加文件保存到磁盘上。我举几个例子：

1. Outlook 是一个单例。您不能同时运行 Outlook 应用程序的两个实例。因此，如果加载的实例在不同的安全内容下运行，您的代码可能会失败。

2. 无法访问目标文件夹。可能是写作权限不足、缺席等。

3. 未找到与代码中定义的条件相对应的 Outlook 项目。

我们可以继续在那里列出假设。但只有日志文件才能揭示您所面临的问题。
