Send mail in JavaMail with gmail smtp

最近用到Java Mail，正在煩惱要用哪個Smtp Server來寄信，就想到用Gmail

附上程式碼....

import java.security.Security;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.sun.net.ssl.internal.ssl.Provider;

public class GmailSend {
private String mailhost = "smtp.gmail.com";

public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception {

Security.addProvider(new Provider());

Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.quitwait", "false");

Session session = Session.getDefaultInstance(props, new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("your@gamil.com", "password@gmail");
}
});

MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(sender,"nickname of sender"));
message.setSubject(subject);
message.setContent(body, "text/plain;charset=big5");
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));

Transport.send(message);
System.out.println("finished!");
}

}

Perl中對URL參數進行編碼

在打工的時候遇到的問題，
今天找了好久，終於找到解決方法了
原來是big5轉utf8的問題…

首先，因為原本存在MySQL中的資料是以big5編碼的，
所以要傳到utf8的網頁當參數時，除了用url的編碼外，
還要用encode編一次，但是這還不夠，
由於是big5碼，所以要先以big5解碼，再轉utf8，
於是…解法如下：
-------------------------------------------------------------------------------
use Encode;
use CGI;

$url_para = encode("utf8",decode("big5",$original_str));

$final_para = uri_escape($url_para);
-------------------------------------------------------------------------------

That's all.

Prototype在Firefox中無法正常運作bug

Prototype.js 1.6.0.3中有一處bug，
導致Ajax.Request對象無法在Firefox下正常運作，
找了好久，終於找到相關的修正方法了…

原版本：
for (var name in headers)
this.transport.setRequestHeader(name, headers[name]);
},

修正後：
for (var name in headers)
if(typeof headers[name] != 'function')
this.transport.setRequestHeader(name, headers[name]);
},

終於可以正常運作了，
只是沒想到這個bug在1.5版就有了。
