API开发指南（ Java 客户端DEMO）

第二步:登录本系统，取得API Key

• 使用用户名与密码登录本系统，进入【系统设置】➞ 找到【API Key管理】。
  
• 找到API Key的Consumer Key和Consumer Secret后，就可以调用SMTP和RESTful接口了。

第三步: 使用API Key调用SMTP接口

• 1. 使用邮件客户端调用SMTP接口，直接进行邮件发送调用，下面用户名密码就是API Key的Consumer Key和Consumer Secret：

  
  

• 或者:

  import java.util.Properties;
  import javax.activation.DataHandler;
  import javax.activation.DataSource;
  import javax.activation.FileDataSource;
  import javax.mail.Authenticator;
  import javax.mail.Message;
  import javax.mail.PasswordAuthentication;
  import javax.mail.Session;
  import javax.mail.Transport;
  import javax.mail.internet.AddressException;
  import javax.mail.internet.InternetAddress;
  import javax.mail.internet.MimeBodyPart;
  import javax.mail.internet.MimeMessage;
  import javax.mail.internet.MimeMultipart;
  import javax.mail.internet.MimeUtility;
  import org.apache.commons.lang3.StringUtils;
  
  public class MySMTP {
  
  	private static final String SMTP_SERVER = "smtp.unimarketing.org";
  	private static final String APIKey = "您的API Key";
  	private static final String APISecret = "您的API Secret";
  
  	public static void main(String[] args) throws Exception {
  
  		Properties properties = new Properties();
  		properties.put("mail.smtp.host", SMTP_SERVER);
  		properties.put("mail.smtp.auth", "true");
  		properties.put("mail.smtp.port", "25");
  		properties.put("mail.transport.protocol", "smtp");
  
  		String fromAddress    = "no-reply@example.com";
  		String recipient      = "someone@customer.com";
  		String subject        = "邮件主题";
  		String fileAttachment = "附件路径";
  		String content        = "邮件正文内容";
  
  		InternetAddress[] receiveAddresses = new InternetAddress[] { new InternetAddress(recipient) };
  
  		Session session = Session.getInstance(properties, new SmtpAuth());
  		session.setDebug(true);
          	session.setDebugOut(new PrintStream("smtp.log"));
  
  		MimeMessage message = new MimeMessage(session);
  		MimeMultipart multipart = new MimeMultipart();
  
  		multipart.setSubType(ContentTypeEnum.ALTERNATIVE.getLabel());
  		MimeBodyPart bodyPart = new MimeBodyPart();
  		bodyPart.setContent(content, "text/html; charset=utf-8");
  		multipart.addBodyPart(bodyPart);
  
  		if (StringUtils.isNotBlank(fileAttachment)) {
  			DataSource dataSource = new FileDataSource(fileAttachment);
  			String name = dataSource.getName();
  			bodyPart = new MimeBodyPart();
  			bodyPart.setDataHandler(new DataHandler(dataSource));
  			bodyPart.setFileName(MimeUtility.encodeText(name));
  			multipart.addBodyPart(bodyPart);
  		}
  
  		message.setSubject(subject);
  		message.setContent(multipart);
  
  		message.setFrom(new InternetAddress(fromAddress));
  		message.setRecipients(Message.RecipientType.TO, receiveAddresses);
  		InternetAddress[] addresses = new InternetAddress[1];
  		addresses[0] = new InternetAddress("someone@somewhere.com");
  		message.setReplyTo(addresses);
  
  		message.addHeader("X-List", MimeUtility.encodeText("联系人列表名称"));
  		message.addHeader("X-Campaign", MimeUtility.encodeText("邮件名称"));
  		Transport.send(message);
  
   /**
     *  获取返回信息
     */
          File file = new File("smtp.log");
          BufferedReader reader = null;
  		try {
  			reader = new BufferedReader(new FileReader(file));
  			String tempString = null;
  			while ((tempString = reader.readLine()) != null) {
  				if (tempString.lastIndexOf("250 ok:") != -1) {
  					System.out.println("返回数据为：" + tempString);
  				}
  			}
  			reader.close();
  		} catch (IOException e) {
  			e.printStackTrace();
  		} finally {
  			if (reader != null) {
  				reader.close();
  			}
  		}
  
  		System.out.println("发送成功");
  	}
  	
  	static class SmtpAuth extends Authenticator {
  		
  		public PasswordAuthentication getPasswordAuthentication() {
  			return new PasswordAuthentication(USER_NAME, PASSWORD);
  		}
  	}
  }
  

• 2. 使用RESTfull接口进行邮件发送调用:

  	UnimailClient unimailClient = UnimailClient.getClient(false, UnimailClient.AuthMode.APIKEY, new String[] { "您的API Key", "您的API Secret" });
  	MessageSendReq msr = new MessageSendReq();
  	msr.setSubject("注册激活通知");		
  	msr.setFrom("no-reply@customer.com");	//【选填】From 地址
  	msr.setReply("services@example.com");	//【选填】回复地址
  	msr.setListName("注册激活列表");		//【必填】列表名称
  	msr.setContent("邮件正文内容");		// 邮件内容
  	msr.setContentType("html");        	// 邮件类型
  	msr.setTo("someone@exanple.com");    	// 收件人
  	msr.setQos(MessageSendReq.QOS_BULK); 	// 非触发交易邮件
  	msr.setMessageName("注册激活通知");   	// 邮件名称
  
  	//发送邮件
  	List trsLists = unimailClient.messageSend(msr);
  	if (trsLists != null) {
  		//获取Message-Id，做后续处理等
  		for (TransactionMailRes transactionMailRes : trsLists) {
  			log.debug(ToStringBuilder.reflectionToString(transactionMailRes,ToStringStyle.MULTI_LINE_STYLE));	
  		}
  	}
