异步使用 Pop3Client

异步使用 Pop3Client

也可以使用 Aspose.Email 异步检索邮箱中的消息 Pop3Client。本文展示了如何异步检索邮箱中的消息，并展示了如何使用 MailQuery.

异步检索消息

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java

Pop3Client client = new Pop3Client();
client.setHost("pop.gmail.com");
client.setPort(995);
client.setSecurityOptions(SecurityOptions.SSLImplicit);
client.setUsername("username");
client.setPassword("password");

try {
    Pop3MessageInfoCollection messages = client.listMessages();
    System.out.println("Total Number of Messages in inbox:" + messages.size());
    IAsyncResult asyncResult = client.beginFetchMessage(messages.get_Item(0).getSequenceNumber());
    MailMessage message = client.endFetchMessage(asyncResult);
} catch (Exception ex) {
    System.out.println(ex.getMessage());
}

使用 MailQuery 异步列出消息

该 MailQuery 类可用于指定检索消息列表的搜索条件，示例代码如下所示。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java

MailQueryBuilder builder = new MailQueryBuilder();
builder.getSubject().contains("Subject");
MailQuery query = builder.getQuery();
IAsyncResult asyncResult = client.beginListMessages(query);
Pop3MessageInfoCollection messages = client.endListMessages(asyncResult);
