我试着增加了通过Android应用程序将订单发送到电子邮件的可能性。但是要被卡住。我在我的谷歌账户中启用了不太安全的访问。起初，我用这种方式。最终，我尝试应用我在这里创建的其他答案中的各种属性，但仍然没有用。
这是我的部分代码：
Properties props = new Properties();
props.put("mail.smtp.user", Utils.EMAIL);
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
mSession = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(Utils.EMAIL, Utils.PASSWORD);
}
});
mSession.setDebug(true);
MimeMessage mm = new MimeMessage(mSession);
try {
mm.setFrom(new InternetAddress(Utils.EMAIL));
mm.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
mm.setSubject(mSubject);
mm.setText(mMessage);
Transport transport = mSession.getTransport("smtps");
transport.connect("smtp.gmail.com", Integer.valueOf("465"), Utils.EMAIL, Utils.PASSWORD);
transport.sendMessage(mm, mm.getAllRecipients());
transport.close();
} catch (AddressException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}

我将感谢任何有用的建议
我知道一个解决方案，但使用的是okHttp客户端。您需要实现一个sslSocketFactory
val client = OkHttpClient.Builder()
.sslSocketFactory(tlsTocketFactory, tlsTocketFactory.trustManager)
.build()
这是TLSSocketFactory类
import java.io.IOException
import java.net.InetAddress
import java.net.Socket
import java.net.UnknownHostException
import java.security.KeyStore
import java.security.KeyStoreException
import java.security.NoSuchAlgorithmException
import java.util.*
import javax.net.ssl.*
class TLSSocketFactory : SSLSocketFactory() {
private val delegate: SSLSocketFactory
private lateinit var trustManagers: Array<TrustManager>
@Throws(KeyStoreException::class, NoSuchAlgorithmException::class)
private fun generateTrustManagers() {
val trustManagerFactory =
TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm())
trustManagerFactory.init(null as KeyStore?)
val trustManagers =
trustManagerFactory.trustManagers
check(!(trustManagers.size != 1 || trustManagers[0] !is X509TrustManager)) {
("Unexpected default trust managers:"
+ Arrays.toString(trustManagers))
}
this.trustManagers = trustManagers
}
override fun getDefaultCipherSuites(): Array<String> {
return delegate.defaultCipherSuites
}
override fun getSupportedCipherSuites(): Array<String> {
return delegate.supportedCipherSuites
}
@Throws(IOException::class)

return enableTLSOnSocket(delegate.createSocket())
}
@Throws(IOException::class)
override fun createSocket(

autoClose: Boolean

return enableTLSOnSocket(delegate.createSocket(s, host, port, autoClose))
}
@Throws(IOException::class, UnknownHostException::class)
override fun createSocket(host: String, port: Int): Socket {
return enableTLSOnSocket(delegate.createSocket(host, port))
}
@Throws(IOException::class, UnknownHostException::class)
override fun createSocket(
host: String,
port: Int,
localHost: InetAddress,
localPort: Int

return enableTLSOnSocket(delegate.createSocket(host, port, localHost, localPort))
}
@Throws(IOException::class)
override fun createSocket(host: InetAddress, port: Int): Socket {
return enableTLSOnSocket(delegate.createSocket(host, port))
}
@Throws(IOException::class)
override fun createSocket(
address: InetAddress,
port: Int,
localAddress: InetAddress,
localPort: Int
): Socket {
return enableTLSOnSocket(delegate.createSocket(address, port, localAddress, localPort))
}
private fun enableTLSOnSocket(socket: Socket): Socket {
if (socket is SSLSocket) {
socket.enabledProtocols = arrayOf(
"TLSv1.1",
"TLSv1.2"
)
}
return socket
}
val trustManager: X509TrustManager?
get() = trustManagers[0] as X509TrustManager
init {
generateTrustManagers()
val context = SSLContext.getInstance("TLS")
context.init(null, trustManagers, null)
delegate = context.socketFactory
}
}
