发送电子邮件 - 可可

Question

我将如何能够使用Cocoa发送电子邮件？我会使用哪个框架，以及如何使用它。

Answer 1

Apple's Developer Connection有一个名为SBSendEmail的示例项目，演示了如何使用脚本桥将脚本发送到邮件应用程序。

您可以下载whole project并在XCode中运行它以查看其工作原理。特别感兴趣的是您的sendEmailMessage：方法Controller.m

Answer 2

您可以使用打开默认mail client或者您可以使用framework。这应该让你开始。

Answer 3

对于Growl 1.2，我写了a Python-based mail-sending program，MailMe显示使用NSTask运行。

我在很大程度上出于对可可的其他邮件框架的不满，其中大部分邮件框架也支持接收邮件，这对于某些输出（如MailMe）来说是不必要的。

Answer 4

我还没看着它在好几年了，但是当我在苹果我主张我们包括它的操作系统，以取代邮件功能，我们会在NeXT/Apple转型中失利。

Answer 5

我认为使用Apple脚本是最简单的解决方案。当用户在Mail中设置帐户时使用它。

Apple脚本：

attachments是一个包含文件路径的stings数组。

“设置为true可见”，如果你想在邮件中发送

- (void)sendEmailWithMail:(NSString *) toAddress withSubject:(NSString *) subject Attachments:(NSArray *) attachments { 
NSString *bodyText = @"Your body text \n\r";  
NSString *emailString = [NSString stringWithFormat:@"\ 
         tell application \"Mail\"\n\ 
         set newMessage to make new outgoing message with properties {subject:\"%@\", content:\"%@\" & return} \n\ 
         tell newMessage\n\ 
         set visible to false\n\ 
         set sender to \"%@\"\n\ 
         make new to recipient at end of to recipients with properties {name:\"%@\", address:\"%@\"}\n\ 
         tell content\n\ 
         ",subject, bodyText, @"McAlarm alert", @"McAlarm User", toAddress ]; 

//add attachments to script 
for (NSString *alarmPhoto in attachments) { 
    emailString = [emailString stringByAppendingFormat:@"make new attachment with properties {file name:\"%@\"} at after the last paragraph\n\ 
        ",alarmPhoto]; 

} 
//finish script 
emailString = [emailString stringByAppendingFormat:@"\ 
       end tell\n\ 
       send\n\ 
       end tell\n\ 
       end tell"]; 



//NSLog(@"%@",emailString); 
NSAppleScript *emailScript = [[NSAppleScript alloc] initWithSource:emailString]; 
[emailScript executeAndReturnError:nil]; 
[emailScript release]; 

/* send the message */ 
NSLog(@"Message passed to Mail"); 

}

缺点之前弹出：用户需要有邮件下有效的帐户。

Python脚本（如果邮件下没有用户帐户）： 您也可以使用python脚本发送消息。 缺点：用户必须输入SMTP详细信息，除非您从邮件中抓取它们（但是您可以使用上面的Apple脚本），或者您必须在应用程序中硬编码一个可靠的SMTP中继（您可以设置一个Gmail帐户并使用它用于这一目的，但如果您的应用程序发送过多的电子邮件，谷歌可以删除自己的帐户（SPAM））
我用这个python脚本：

import sys 
import smtplib 
import os 
import optparse 

from email.MIMEMultipart import MIMEMultipart 
from email.MIMEBase import MIMEBase 
from email.MIMEText import MIMEText 
from email.Utils import COMMASPACE, formatdate 
from email import Encoders 

username = sys.argv[1] 
hostname = sys.argv[2] 
port = sys.argv[3] 
from_addr = sys.argv[4] 
to_addr = sys.argv[5] 
subject = sys.argv[6] 
text = sys.argv[7] 

password = getpass.getpass() if sys.stdin.isatty() else sys.stdin.readline().rstrip('\n') 

message = MIMEMultipart() 
message['From'] = from_addr 
message['To'] = to_addr 
message['Date'] = formatdate(localtime=True) 
message['Subject'] = subject 
#message['Cc'] = COMMASPACE.join(cc) 
message.attach(MIMEText(text)) 

i = 0 
for file in sys.argv: 
    if i > 7: 
     part = MIMEBase('application', 'octet-stream') 
     part.set_payload(open(file, 'rb').read()) 
     Encoders.encode_base64(part) 
     part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(file)) 
     message.attach(part) 
    i = i + 1 

smtp = smtplib.SMTP(hostname,port) 
smtp.starttls() 
smtp.login(username, password) 
del password 

smtp.sendmail(from_addr, to_addr, message.as_string()) 
smtp.close() 

而且我把它形成这个方法使用发送电子邮件Gmail帐户

- (bool) sendEmail:(NSTask *) task toAddress:(NSString *) toAddress withSubject:(NSString *) subject Attachments:(NSArray *) attachments { 

     NSLog(@"Trying to send email message"); 
     //set arguments including attachments 
     NSString *username = @"my.gmail.account@gmail.com"; 
     NSString *hostname = @"smtp.gmail.com"; 
     NSString *port = @"587"; 
     NSString *fromAddress = @"my.gmail.account@gmail.com"; 
     NSString *bodyText = @"Body text \n\r"; 
     NSMutableArray *arguments = [NSMutableArray arrayWithObjects: 
            programPath, 
            username, 
            hostname, 
            port, 
            fromAddress, 
            toAddress, 
            subject, 
            bodyText, 
            nil]; 
     for (int i = 0; i < [attachments count]; i++) { 
      [arguments addObject:[attachments objectAtIndex:i]]; 
     } 

     NSData *passwordData = [@"myGmailPassword" dataUsingEncoding:NSUTF8StringEncoding]; 


     NSDictionary *environment = [NSDictionary dictionaryWithObjectsAndKeys: 
            @"", @"PYTHONPATH", 
            @"/bin:/usr/bin:/usr/local/bin", @"PATH", 
            nil]; 
     [task setEnvironment:environment]; 
     [task setLaunchPath:@"/usr/bin/python"]; 

     [task setArguments:arguments]; 

     NSPipe *stdinPipe = [NSPipe pipe]; 
     [task setStandardInput:stdinPipe]; 

     [task launch]; 

     [[stdinPipe fileHandleForReading] closeFile]; 
     NSFileHandle *stdinFH = [stdinPipe fileHandleForWriting]; 
     [stdinFH writeData:passwordData]; 
     [stdinFH writeData:[@"\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
     [stdinFH writeData:[@"Description" dataUsingEncoding:NSUTF8StringEncoding]]; 
     [stdinFH closeFile]; 

     [task waitUntilExit]; 

     if ([task terminationStatus] == 0) { 
      NSLog(@"Message successfully sent"); 
      return YES; 
     } else { 
      NSLog(@"Message not sent"); 
      return NO; 
     } 
    } 

我希望它有帮助
