如何在mailcore2中获取电子邮件正文

Question

我试图从mailcore迁移到mailcore2.以前在mailcore中,获取正文结构就像[msg fetchBodyStructure]msg是CTCoreMessage对象一样简单.

使用mailcore2,事情似乎更复杂.在MCOIMAPSession的获取消息体的文档中,我们有:

MCOIMAPFetchContentOperation * op = 
    [session fetchMessageAttachmentByUIDOperationWithFolder:@"INBOX"
                                                        uid:[message uid]
                                                     partID:"1.2"
                                                   encoding:[part encoding]];
 [op start:^(NSError * error, NSData * partData) {
 }];

我完全不知道这1.2应该是指什么.作者将用户引用到RFC 822,RFC 2822和RFC 5322,但没有一个能够直接回答上述问题.

有人可以告诉我一个获取整个邮件正文的简单代码示例吗？

我不确定为什么人们会使事情变得复杂:这就是你用MailCore2获取邮件正文的方法:

MCOIMAPSession *session = [[MCOIMAPSession alloc] init];
    [session setHostname:@"imap.gmail.com"];
    [session setPort:993];
    [session setUsername:[UICKeyChainStore stringForKey:@"username"]];
    [session setPassword:[UICKeyChainStore stringForKey:@"password"]];
    [session setConnectionType:MCOConnectionTypeTLS];
    MCOIMAPFetchContentOperation *operation = [session fetchMessageByUIDOperationWithFolder:@"INBOX" uid:message.uid];

    [operation start:^(NSError *error, NSData *data) {
        MCOMessageParser *messageParser = [[MCOMessageParser alloc] initWithData:data];

        NSString *msgHTMLBody = [messageParser htmlBodyRendering];
        [webView loadHTMLString:msgHTMLBody baseURL:nil];
    }];
