就地存档(也称为在线存档或无限存档)是企业邮箱系统中用于长期存储邮件的功能,它不同于传统的PST文件存档,而是直接在服务器上存储邮件数据,用户可以通过客户端或API访问。
对于Microsoft Exchange环境,可以使用EWS(Exchange Web Services)或Microsoft Graph API访问存档邮箱。
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);
service.Credentials = new WebCredentials("username", "password");
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
// 搜索存档邮箱中的邮件
ItemView view = new ItemView(10);
FindItemsResults<Item> findResults = service.FindItems(
WellKnownFolderName.ArchiveInbox,
new ItemView(10));
foreach (EmailMessage email in findResults.Items.OfType<EmailMessage>())
{
Console.WriteLine("Subject: " + email.Subject);
Console.WriteLine("Received: " + email.DateTimeReceived);
}
GET https://graph.microsoft.com/v1.0/users/{user-id}/mailFolders/archive/messages
Authorization: Bearer {access-token}
某些邮箱系统允许通过IMAP协议访问存档邮箱:
import imaplib
mail = imaplib.IMAP4_SSL('imap.example.com')
mail.login('user@example.com', 'password')
mail.select('Archive') # 选择存档邮箱
status, messages = mail.search(None, 'ALL')
for num in messages[0].split():
status, data = mail.fetch(num, '(RFC822)')
print(data[0][1])
通过API访问存档邮箱是可行的,但具体实现方式取决于使用的邮件系统和技术栈。
