从Cocoa发送电子邮件 [英] Send email from Cocoa
问题描述
如何从Cocoa应用程式传送电子邮件，而不使用任何电子邮件用户端？我有NSURL，但它打开一个电子邮件客户端。
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.
推荐答案
更新：正如其他人所建议的，从 10.9 您可以使用支持附件的 NSSharingService ！
UPDATE: As others suggested, from 10.9 you can use NSSharingService that supports attachments as well!
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
}
旧版更新：我的旧答案工作正常，直到我必须为我的应用商店沙箱我的应用程序~~
从那时起，我找到的唯一解决方案只使用一个mailto：链接。
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.
- (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：没有附件！如果你知道如何让它在Mac上工作让我知道！
Disadvantage: No attachment! If you know how to make it work on Mac let me know!
老问答：
你可以Apple脚本桥梁框架（解决方案2）或Python脚本（解决方案3）
OLD ANSWER: You can Apple Script, Apple's scripting bridge framework (Solution 2) or a Python script (Solution 3)
解决方案1（Apple脚本）：
Solution 1 (Apple script):
attachments是包含文件路径的字符串数组
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");
}
解决方案2框架）：
您可以使用Apple的scriptingbridge框架使用Mail发送您的邮件
苹果的示例链接这很简单，你只需要干脆向你的项目添加规则和Mail.app。仔细阅读Readme.txt。
Solution 2 (Apple scriptingbridge framework):
You can use Apple's scriptingbridge framework to use Mail to send your message
Apple's exmaple link it's pretty straightforward, you only need to fiddle with adding a rule and Mail.app to your project. Read Readme.txt carefully.
更改emailMessage.visible = YES;到emailMessage.visible = NO;因此它会在后台发送。
Change "emailMessage.visible = YES;" to "emailMessage.visible = NO;" so it sends it in the background.
缺点：用户需要在Mail下拥有有效的帐户。
Disadvantage: users need to have valid accounts under Mail.
解决方案3（Python脚本（无用户帐户）：
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抓取它们（但是您可以使用解决方案1直接），或者你必须有一个可靠的SMTP中继硬编码在你的应用程序（你可以设置一个gmail帐户，并使用它的目的，但如果你的应用程序发送太多的电子邮件google可以删除你的帐户（垃圾邮件） ）
我使用这个python脚本：
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()
我使用gmail帐户发送电子邮件，形成这个方法。
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 = @"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;
}
}
我希望它有助于
