我试图用Java发送一封电子邮件:
import java.util.*; import javax.mail.*; import javax.mail.internet.*; import javax.activation.*; public class SendEmail { public static void main(String [] args) { // Recipient's email ID needs to be mentioned. String to = "abcd@gmail.com"; // Sender's email ID needs to be mentioned String from = "web@gmail.com"; // Assuming you are sending email from localhost String host = "localhost"; // Get system properties Properties properties = System.getProperties(); // Setup mail server properties.setProperty("mail.smtp.host", host); // Get the default Session object. Session session = Session.getDefaultInstance(properties); try{ // Create a default MimeMessage object. MimeMessage message = new MimeMessage(session); // Set From: header field of the header. message.setFrom(new InternetAddress(from)); // Set To: header field of the header. message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Set Subject: header field message.setSubject("This is the Subject Line!"); // Now set the actual message message.setText("This is actual message"); // Send message Transport.send(message); System.out.println("Sent message successfully...."); }catch (MessagingException mex) { mex.printStackTrace(); } } }
我得到了错误:
javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is:java.net.ConnectException: Connection refused: connect at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1706) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:525)
这段代码能用来发送电子邮件吗?
代码:
import java.io.UnsupportedEncodingException; import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; 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.MimeMessage; public class SendMail { public static void main(String[] args) { final String username = "your_user_name@gmail.com"; final String password = "yourpassword"; Properties props = new Properties(); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.port", "587"); Session session = Session.getInstance(props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress("your_user_name@gmail.com")); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("to_email_address@domain.com")); message.setSubject("Testing Subject"); message.setText("Dear Mail Crawler," + "\n\n No spam to my email, please!"); Transport.send(message); System.out.println("Done"); } catch (MessagingException e) { throw new RuntimeException(e); } } }
目前呼叫中心只有API文档,需要用户自己开发。如果用户需要saas系统的呼叫中心可以使用智能外呼机器人:https://cloud.tencent.com/product/ccsr
你有没有调整观众端表现,即通过对 LivePushConfig 中的homeOrientation设置项进行配置,它控制的是观众端看到的视频宽高比是16:9还是6:19,调整后的结果可以用播放器查看以确认是否符合预期。
控制台使用的是新的接口,批量创建子网,https://cloud.tencent.com/document/product/215/31960,可以指定路由表。terraform开发的时候是基于api2.0开发的,还没有这个接口,因此暂时无法使用
