我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但它会打开一个电子邮件客户端。我希望在没有此类情况发生的情况下发送电子邮件。

这些响应已经过时,对于 Mac OS X 10.8 及以上版本,您应该使用 NSSharingService。
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];
NSSharingService
是 10.8+ 版本可用,但 recipients
和 subject
属性仅在 10.9+ 版本以上可用,因此如果你的目标是 10.8 版本,应该添加一个 respondToSelector:
测试。 - Vincent Tourraine更新:正如其他人建议的那样,从 10.9 版本开始,您可以使用 NSSharingService,它也支持附件!
Swift 示例:
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
}
旧更新: 我之前的答案一直有效,直到我不得不为应用商店对我的应用进行沙盒处理。自那以后,我找到的唯一解决方案就是简单使用一个 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);
}
缺点:无附件!如果您知道如何在Mac上运行它,请告诉我!
旧答案:您可以使用Apple Script,苹果公司的脚本桥接框架(解决方案2)或Python脚本(解决方案3)
解决方案1(Apple脚本):
attachments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");
}
Solution 2(苹果ScriptingBridge框架): 您可以使用苹果的ScriptingBridge框架来使用Mail发送邮件。 苹果示例链接,非常简单,您只需要调整添加规则和Mail.app到您的项目中。仔细阅读Readme.txt。
将“emailMessage.visible = YES;”更改为“emailMessage.visible = NO;”,以便在后台发送。
缺点:用户需要在Mail下拥有有效帐户。
Solution 3(Python脚本(无用户帐户): 您还可以使用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(但然后您可以直接使用上述解决方法1),或者您必须在应用程序中硬编码可靠的SMTP中继(您可以设置一个gmail帐户并将其用于此目的,但如果您的应用程序发送太多电子邮件,谷歌可能会删除您的帐户(SPAM)) 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()
我使用这个方法调用它,以便使用Gmail账户发送电子邮件。
- (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;
}
}
希望这能有所帮助。
