問題描述

我正在使用自定義 SMTP 服務器，并希望在用戶輸入自己的服務器憑據時驗證連接.

I'm using custom SMTP servers and would like to verify the connection when user enters his own server credentials.

與 Adob??e CF 和 Railo 在添加郵件服務器時允許執行的檢查類型完全相同.

Exactly the same type of check as Adobe CF and Railo allow to do when adding mail server.

當然，這并不能保證 delivery 會正常工作，但至少要檢查輸入的服務器/用戶名/密碼是否有效.

Sure, this does not guarantee that delivery will be working, but at least to check that entered server/username/pass are valid.

我可以看到一種棘手的方法:嘗試使用 cfmail 發送電子郵件并檢查郵件日志.但我相信它可以做得更優雅.

I can see one tricky way: try to send the email with cfmail and check the mail log. But I believe that it can be done with more elegant.

標準 ACF/Railo 發行版中是否有任何 Java 庫可以幫助我?我將如何使用它們?非常感謝示例.

Is there any Java library available with standard ACF/Railo distro to help me? How would I use them? Examples are highly appreciated.

提前致謝.

請不要與存在的 Java 標記相混淆.CFML 中需要解決方案.雖然它可以使用一些 Java 庫(如果適用).

Please don't be confused with Java tag present. Solution needed in CFML. Though it can use some Java libraries, if applicable.

我認為 sfussenegger 的想法是對的.但是不是使用自定義身份驗證器，而是通過 connect(..) 進行身份驗證呢?只用gmail測試過.但它似乎工作.

I think sfussenegger has the right idea. But instead of using a custom authenticator, what about authenticating via connect(..)? Only tested with gmail. But it seems to work.

我用 CF9 &OBD成功.不幸的是，我在 Railo 上沒有運氣……真可惜.

I tested this with CF9 & OBD successfully. Unfortunately, I had no luck with Railo ... bummer.

已更新以添加缺少的mail.smtp.auth"屬性.它現在應該也可以與 Railo 一起正常工作了.

Updated to add the missing "mail.smtp.auth" property. It should now work correctly with Railo as well.

    //Java Version
    int port = 587;
    String host = "smtp.gmail.com";
    String user = "username@gmail.com";
    String pwd = "email password";

    try {
        Properties props = new Properties();
        // required for gmail 
        props.put("mail.smtp.starttls.enable","true");
        props.put("mail.smtp.auth", "true");
        // or use getDefaultInstance instance if desired...
        Session session = Session.getInstance(props, null);
        Transport transport = session.getTransport("smtp");
        transport.connect(host, port, user, pwd);
        transport.close();
        System.out.println("success");
     } 
     catch(AuthenticationFailedException e) {
           System.out.println("AuthenticationFailedException - for authentication failures");
           e.printStackTrace();
     }
     catch(MessagingException e) {
           System.out.println("for other failures");
           e.printStackTrace();
     }



<cfscript>
    //CF Version
    port = 587;
    host = "smtp.gmail.com";
    user = "username@gmail.com";
    pwd = "email password";

    try {
        props = createObject("java", "java.util.Properties").init();
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.auth", "true");
        // or use getDefaultInstance instance if desired...
        mailSession = createObject("java", "javax.mail.Session").getInstance(props, javacast("null", ""));
        transport = mailSession.getTransport("smtp");
        transport.connect(host, port, user, pwd);
        transport.close();
        WriteOutput("success");
     } 
     //for authentication failures
     catch(javax.mail.AuthenticationFailedException e) {
           WriteOutput("Error: "& e.type &" ** "& e.message);
     }
     // for other failures
     catch(javax.mail.MessagingException e) {
           WriteOutput("Error: "& e.type &" ** "& e.message);
     }
</cfscript>
