發送可可電子郵件

Question

如何在不使用任何電子郵件客戶端的情況下從Cocoa應用程序發送電子郵件？我有NSURL，但它打開了一個電子郵件客戶端。我想在沒有發生這種情況的情況下發送電子郵件。

Answer 1

更新：正如其他人建議，從10.9可以使用NSSharingService支持附件以及！

斯威夫特例如：

let emailImage   = NSImage.init(named: "ImageToShare")! 
    let emailBody   = "Email Body" 
    let emailService  = NSSharingService.init(named: NSSharingServiceNameComposeEmail)! 
    emailService.recipients = ["support@myapp.com"] 
    emailService.subject = "App Support" 

    if emailService.canPerform(withItems: [emailBody,emailImage]) { 
     // email can be sent 
     emailService.perform(withItems: [emailBody,emailImage]) 
    } else { 
     // email cannot be sent, perhaps no email client is set up 
     // Show alert with email address and instructions 

    } 

舊的更新：我老的答案工作的罰款，直到我不得不沙箱爲App Store我的應用程序~~ 從那以後，我發現的唯一的解決方案是使用只需一個mailto：鏈接。

- (void)sendEmailWithMail:(NSString *) senderAddress Address:(NSString *) toAddress Subject:(NSString *) subject Body:(NSString *) bodyText { 
    NSString *mailtoAddress = [[NSString stringWithFormat:@"mailto:%@?Subject=%@&body=%@",toAddress,subject,bodyText] stringByReplacingOccurrencesOfString:@" " withString:@"%20"]; 
    [[NSWorkspace sharedWorkspace] openURL:[NSURL URLWithString:mailtoAddress]]; 
    NSLog(@"Mailto:%@",mailtoAddress); 
} 

缺點：沒有附件！如果你知道如何使它在Mac上工作，讓我知道！

OLD答： 您可以在Apple腳本，蘋果的腳本橋框架（方案二）或Python腳本（方案三）

解決方案1（蘋果腳本）：

附件是一個數組包含文件路徑刺

- (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"); 

}

SOLU您可以使用Apple的scriptingbridge框架使用Mail發送您的消息
Apple's exmaple link這很簡單，您只需要添加一條規則和Mail.app到您的項目中。仔細閱讀Readme.txt。

更改「emailMessage.visible = YES;」到「emailMessage.visible = NO;」所以它在後臺發送它。

缺點：用戶需要在郵件下擁有有效的帳號。

解決方案3（Python腳本（無用戶帳戶）： 您還可以使用python腳本發送消息。 缺點：用戶必須輸入SMTP的詳細信息，除非您從郵件中抓取郵件（但您可以直接使用上面的解決方案1），或者您必須在應用中使用硬編碼的可靠SMTP中繼（您可以設置Gmail帳戶並使用它用於這一目的，但如果您的應用程序發送過多的電子郵件，谷歌可以刪除自己的帳戶（SPAM））
我用這個python腳本：

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() 

而且我把它形成這個方法使用發送電子郵件Gmail帳戶

- (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; 
     } 
    } 

我希望它有幫助

Answer 2

這post應該幫助 - 它也引用example code。

您還需要更改Controller.m或者線114在後臺發送消息：

emailMessage.visible = NO; 

Answer 3

您將需要使用Simple Mail Transfer Protocol（SMTP）。這個鏈接將給你簡單的介紹它是如何工作的：Understanding the SMTP Protocol。

Answer 4

這些反應是過時的Mac OS X 10.8，更應該使用NSSharingService

[啞劇

NSArray *shareItems=@[body,imageA,imageB]; 
NSSharingService *service = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail]; 
service.delegate = self; 
service.recipients=@[@"xxx@apple.com"]; 
service.subject= [ NSString stringWithFormat:@"%@ %@",NSLocalizedString(@"SLYRunner console",nil),currentDate]; 
[service performWithItems:shareItems]; 

The sharing service documentation page
