02 let mail = Mail(
03         text: "Across the great wall we can reach every corner in the world.", 
04         from: "onev@onevcat.com", 
05         to: "foo@bar.com", 
06         subject: "Hello World"
07 )
08
09 hedwig.send(mail) { error in
10     if error != nil { /* Error happened */ }
11 }


发送html邮件： 

01 lethedwig = Hedwig(hostName: "smtp.example.com", user: "foo@bar.com", password: "password")
02 letattachement = Attachment(htmlContent: "<html><body><h1>Title</h1><p>Content</p></body></html>")
03 let mail = Mail(
04         text: "Fallback text", 
05         from: "onev@onevcat.com", 
06         to: "foo@bar.com", 
07         subject: "Title",

09 )
10 hedwig.send(mail) { error in
11     if error != nil { /* Error happened */ }
12 }


抄送和暗抄送： 

01 lethedwig = Hedwig(hostName: "smtp.example.com", user: "foo@bar.com", password: "password")
02 let mail = Mail(
03         text: "Across the great wall we can reach every corner in the world.", 
04         from: "onev@onevcat.com", 
05         to: "foo@bar.com",
06         cc: "Wei Wang <onev@onevcat.com>, tom@example.com"// Addresses will be parsed for you
07         bcc: "My Group: onev@onevcat.com, foo@bar.com;"    // Even with group syntax
08         subject: "Hello World"
09 )
10 hedwig.send(mail) { error in
11     if error != nil { /* Error happened */ }
12 }


SMTP设置： 

01 let hedwig = Hedwig(
02         hostName: "smtp.example.com", 
03         user: "foo@bar.com", 
04         password: "password",
05         port: 1234,     // Determined from secure layer by default
06         secure: .plain, // .plain (Port 25) | .ssl (Port 465) | .tls (Port 587) (default)
07         validation: .default, // You can set your own certificate/cipher/protocols
08         domainName: "onevcat.com", // Used when saying hello to STMP Server
09         authMethods: [.plain, .login] // Default: [.plain, .cramMD5, .login, .xOauth2]        
10 )


发送图片和附件： 

01 let imagePath = "/tmp/image.png"
02 // You can create an attachment from a local file path.
03 let imageAttachment = Attachment(
04         filePath: imagePath, 
05         inline: true, 
06         // Add "Content-ID" if you need to embed this image to another attachment.
07         additionalHeaders: ["Content-ID": "hedwig-image"] 
08 )
09 let html = Attachment(
10         htmlContent: "<html><body>A photo <img src=\"cid:hedwig-image\"/></body></html>", 
11         // If imageAttachment only used embeded in HTML, I recommend to set it as related.
12         related: [imageAttachment]
13 )
14
15 // You can also create attachment from raw data.
16 let data = "{\"key\": \"hello world\"}".data(using: .utf8)!
17 let json = Attachment(
18         data: data, 
19         mime: "application/json", 
20         name: "file.json", 
21         inline: false // Send as standalone attachment.
22 )
23
24 let mail = Mail(
25         text: "Fallback text", 
26         from: "onev@onevcat.com", 
27         to: "foo@bar.com", 
28         subject: "Check the photo and json file!",
29         attachments: [html, json]
30 hedwig.send(mail) { error in
31     if error != nil { /* Error happened */ }
32 }


发送给多个收件人： 

01 let mail1: Mail = //...
02 let mail2: Mail = //...
03
04 hedwig.send([mail1, mail2], 
05         progress: { (mail, error) in
06             if error != nil { 
07                 print("\(mail) failed. Error: \(error)") 
08             }
09         },
10         completion: { (sent, failed) in
11             for mail in sent {
12                 print("Sent mail: \(mail.messageId)")
13             }
14
15             for (mail, error) in failed {
16                 print("Mail \(mail.messageId) errored: \(error)")
17             }
18         }
