我有两个相似的代码部分,用
java和PHP编写.由于证书错误,PHP没有发送电子邮件 –
Connection Failed. Error #2: stream_socket_enable_crypto(): Peer certificate CN=*.hosting.com' did not match expected CN=smtp.anotherhosting.com'
但java代码发送电子邮件没有任何问题,我无法理解为什么. (从任何地方我都看到问题 – how to skip ssl checks with java?
这是代码：
PHP：
<?PHP require './PHPMailer.PHP'; require './SMTP.PHP'; use PHPMailer\PHPMailer\PHPMailer; $mail = new PHPMailer(true); try { $mail->SMTPDebug = 4; $mail->isSMTP(); $mail->Host = 'smtp.anotherhosting.com'; $mail->SMTPAuth = true; $mail->Username = 'username@anotherhosting.com'; $mail->Password = 'password'; $mail->SMTPSecure = 'tls'; $mail->Port = 587; //Recipients $mail->setFrom('from@company.com'); $mail->addAddress('myemail@company.com'); $mail->isHTML(true); $mail->Subject = 'Here is the subject12'; $mail->Body = 'This is the HTML message bo22dy <b>in bold!</b>'; $mail->send(); echo 'Message has been sent'; } catch (Exception $e) { echo 'Message Could not be sent. Mailer Error: ',$mail->ErrorInfo; } try { $mail->smtpClose(); } catch (Exception $e) { echo $e->getTraceAsstring(); }
和java：
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Main {
public static void main(String[] args) {
final String username = "username@anotherhosting.com";
final String password = "password";
Properties props = new Properties();
props.put("mail.smtp.auth","true");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.host","smtp.anotherhosting.com");
props.put("mail.smtp.port","587");
Session session = Session.getInstance(props,new javax.mail.Authenticator() {
protected PasswordAuthentication getpasswordAuthentication() {
return new PasswordAuthentication(username,password);
}
});
session.setDebug(true);
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("from@company.com"));
message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("myemail@company.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);
}
}
}
我的任务是使用PHP代码实现电子邮件发送功能.从我目前的角度来看,由于从一个主机到另一个主机的smtp重定向,它失败了.最有可能的是,PHPmailer获取host1,接收重定向到host2,从host2获取证书并将此证书与host1进行比较.同时,java客户端做的一切都很好.如果有人知道如何解决这个问题,请告诉我.
此外,当它试图调用stream_socket_enable_crypto时,PHP代码在line 402失败.
这是日志文件：

对.因此,您的Java代码存在一个允许中间人攻击成功的错误.在PHP中,通过完全按照TLS设计的方式,它成功地阻止了这一点.
发生了什么事情是ISP的防火墙上的TCP重定向,这对两个客户端都是不可见的.您可以禁用证书检查(如the troubleshooting guide中所述),但实际上您不应该这样做.要么显式连接到正确的名称(mailpod.hosting.com),要么使用不会篡改您的流量的托管服务提供商.
