react native android设置邮箱，进行邮件发送

引入发送邮件的架包。

在build.gradle 的dependencies 下引入：

复制代码

 //发送邮件的依赖
 implementation 'com.sun.mail:android-mail:1.6.7'
 implementation 'com.sun.mail:android-activation:1.6.7'

导入EmailSender类

复制代码

 import android.widget.Toast;
 
 import java.util.Properties;
 
 import javax.mail.Authenticator;
 import javax.mail.Message;
 import javax.mail.MessageRemovedException;
 import javax.mail.MessagingException;
 import javax.mail.PasswordAuthentication;
 import javax.mail.Session;
 import javax.mail.Transport;
 import javax.mail.internet.InternetAddress;
 import javax.mail.internet.MimeMessage;
 
 public class EmailSender {
     private String username;
     private String password;
     private String host;
     private String port;
 
 
     public EmailSender(String username,String password,String host,String port){
         this.username = username;
         this.password = password;
         this.host = host;
         this.port = port;
 
     }
 
     public void sendEmail(String to, String subject , String text){
 
         Properties properties = new Properties();
         properties.put("mail.smtp.auth",true);
         properties.put("mail.smtp.starttls.enable",true);
         properties.put("mail.smtp.host",host);
         properties.put("mail.smtp.port",port);
 
         Session session = Session.getInstance(properties, new Authenticator() {
             @Override
             protected PasswordAuthentication getPasswordAuthentication() {
                 return new PasswordAuthentication(username,password);
             }
         });
 
         try {
             Message message = new MimeMessage(session);
             message.setFrom(new InternetAddress(username));
             message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to));
             message.setSubject(subject);
             message.setText(text);
 
 
             Transport.send(message);
 
         } catch (MessagingException e){
             e.printStackTrace();
         }
 
     }
 
 }

在NativeModule 中调用。

username：账户名、邮箱

password：密码

host:主机

port:端口

to:发送的邮箱

subject:主题

text:内容

复制代码

	@ReactMethod
	    public void sendEmail(String username,String password,String host,String port,String to,String subject,String text) {
	
	        new Thread(new Runnable() {
	            @Override
	            public void run() {
	                EmailSender emailSender = new EmailSender(username,password,host,port);
	
	                emailSender.sendEmail(to,subject,text);
	            }
	        }).start();
	

}
