使用Python从Outlook下载附件

Question

我正在尝试使用Python从Outlook下载附件，到目前为止可以按主题行下载附件，但在我的情况下，我想从主题行以某些字符串开头的多个电子邮件中下载多个附件，例如:主题是:查询123654，查询56975，查询5698像这样，我想下载主题名称以“查询”开头的所有附件。我当前的代码如下：

from win32com.client import Dispatch
outlook = Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder("6")
all_inbox = inbox.Items
val_date = datetime.date.today()

sub_today = 'Query 123654'
att_today = ''
for msg in all_inbox:
    if msg.Subject == sub_today and msg.Senton.date() == val_date:
        break

for att in msg.Attachments:
    if att.FileName == att_today:
        break

try:
    att.SaveAsFile('C:\\Offline Feeds\\Attachments' + '\\'+ att.FileName)
    messagebox.showinfo("SUCCESSFUL","Attachments Downloaded")
except:
    messagebox.showerror("ERROR","Attachment Download Failed")

Answer 1

您可以使用find()来搜索特定数据。

sub_today = 'Query'

if msg.Subject.find(sub_today) != -1 break

如果subject中不包含Query，则返回-1。

这是完整的代码：

from win32com.client import Dispatch
outlook = Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder("6")
all_inbox = inbox.Items
val_date = datetime.date.today()

sub_today = 'Query'
att_today = ''
for msg in all_inbox:
    if msg.Subject.find(sub_today) != -1 and msg.Senton.date() == val_date:
        break

for att in msg.Attachments:
    if att.FileName == att_today:
        break

try:
    att.SaveAsFile('C:\\Offline Feeds\\Attachments' + '\\'+ att.FileName)
    messagebox.showinfo("SUCCESSFUL","Attachments Downloaded")
except:
    messagebox.showerror("ERROR","Attachment Download Failed")
