Send email from Cocoa
提问by Lenny Magico
How can I send an email from a Cocoa app without using any email clients ? I have NSURL but it opens up an email client. I would like to send the email without this happening.
如何在不使用任何电子邮件客户端的情况下从 Cocoa 应用程序发送电子邮件？我有 NSURL 但它打开了一个电子邮件客户端。我想在没有发生这种情况的情况下发送电子邮件。

Those response are outdated Mac OS X 10.8 and more you should use NSSharingService
这些响应是过时的 Mac OS X 10.8 和更多你应该使用 NSSharingService
NSArray *shareItems=@[body,imageA,imageB];
NSSharingService *service = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail];
service.delegate = self;
service.recipients=@[@"[email protected]"];
service.subject= [ NSString stringWithFormat:@"%@ %@",NSLocalizedString(@"SLYRunner console",nil),currentDate];
[service performWithItems:shareItems];

UPDATE: As others suggested, from 10.9you can use NSSharingServicethat supports attachments as well!
更新：正如其他人所建议的，从10.9 开始，您也可以使用支持附件的NSSharingService！
Swift example:
快速示例：
let emailImage = NSImage.init(named: "ImageToShare")!
let emailBody = "Email Body"
let emailService = NSSharingService.init(named: NSSharingServiceNameComposeEmail)!
emailService.recipients = ["[email protected]"]
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
}
OLD UPDATE: My old answers worked fine until I had to sandbox my apps for the App Store.~~
Since then the only solution I found was using simply a mailto: link.
旧更新：我的旧答案运行良好，直到我不得不为 App Store 沙盒我的应用程序。~~从那时起，我找到的唯一解决方案就是使用简单的 mailto: 链接。
- (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);
}
Disadvantage: No attachment! If you know how to make it work on Mac let me know!
OLD ANSWER:You can Apple Script, Apple's scripting bridge framework (Solution 2) or a Python script (Solution 3)
Solution 1 (Apple script):
attachments is an array of stings containing file paths
- (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");
}
Solution 2 (Apple scriptingbridge framework):
You can use Apple's scriptingbridge framework to use Mail to send your message
Apple's exmaple linkit's pretty straightforward, you only need to fiddle with adding a rule and Mail.app to your project. Read Readme.txt carefully.
Change "emailMessage.visible = YES;" to "emailMessage.visible = NO;" so it sends it in the background.
Disadvantage: users need to have valid accounts under Mail.
Solution 3 (Python Script (no user account):
You can also use a python script to send a message.
Disadvantage: users have to enter SMTP details unless you grab them from Mail (but then you can use Solution 1 above directly), or you have to have a reliable SMTP relay hardcoded in your app (you can set up a gmail account and use it for that purpose, however if your apps send too many emails google can delete your account (SPAM))
I use this python script:
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()
And I call it form this method to send an email using a gmail account
- (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 = @"[email protected]";
NSString *hostname = @"smtp.gmail.com";
NSString *port = @"587";
NSString *fromAddress = @"[email protected]";
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;
}
}
- (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);
}
缺点：无附件！如果您知道如何在 Mac 上运行，请告诉我！
旧答案：您可以使用 Apple Script、Apple 的脚本桥接框架（解决方案 2）或 Python 脚本（解决方案 3）
解决方案 1（Apple 脚本）：
附件是包含文件路径的字符串数组
- (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");
}
解决方案2（Apple scriptingbridge 框架）：您可以使用Apple 的scriptingbridge 框架来使用Mail 发送您的消息
Apple 的示例链接非常简单，您只需要在项目中添加规则和Mail.app 即可。仔细阅读 Readme.txt。
更改“emailMessage.visible = YES;” 到“emailMessage.visible = NO;” 所以它在后台发送它。
缺点：用户需要在Mail下拥有有效的帐户。
解决方案3（Python脚本（无用户帐户）：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Mail中获取它们（但是您可以直接使用上面的解决方案1），或者你必须在你的应用程序中有一个可靠的 SMTP 中继（你可以设置一个 gmail 帐户并将其用于此目的，但是如果你的应用程序发送太多电子邮件谷歌可以删除你的帐户（垃圾邮件））
我使用这个 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()
我称之为使用 gmail 帐户发送电子邮件的这种方法
- (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 = @"[email protected]";
NSString *hostname = @"smtp.gmail.com";
NSString *port = @"587";
NSString *fromAddress = @"[email protected]";
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;
}
}
I hope it helps
我希望它有帮助

This postshould help - it cites example codetoo.
You also need to change line 114 in Controller.m to send the message in the background:
您还需要更改 Controller.m 中的第 114 行以在后台发送消息：
emailMessage.visible = NO;
