在我的网站中,我有一个链接忘记密码,当我点击此链接时,页面将会出现,所以我们填写emailId并发送邮件到特定的gmailid(在这封邮件中我们必须生成一个链接) 。当我们点击生成的链接页面打开重置密码(如新密码ar确认密码)。
我的问题是我能够成功发送邮件,但点击链接时无法找到emailId 用于重置密码。 Gmail链接:
http://127.0.0.1:8888/abc.html?gwt.codesvr=127.0.0.1:9997#forgetPassword
客户代码
sendButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
// TODO Auto-generated method stub
greetServer.mailLinkSend(emailId.getText(),"http://"+Window.Location.getHost()+Window.Location.getPath()+Window.Location.getQueryString()+"#forgetPassword", new AsyncCallback<String>() {
@Override
public void onSuccess(String result) {
// TODO Auto-generated method stub
System.out.println("success"+result);
}
@Override
public void onFailure(Throwable caught) {
// TODO Auto-generated method stub
System.out.println("fail");
}
});
}
});
服务器上的
public String mailLinkSend(String emailText, String link) {
SecretKey key = KeyGenerator.getInstance("DES").generateKey();
//创建加密/解密器类 DesEncrypter encrypter = new DesEncrypter(key);
//加密 encrypted = encrypter.encrypt(emailText);
//解密 String decrypted = encrypter.decrypt(encrypted);
String ss = "true";
String emailMsgTxt = "Hi" + emailText + "\n" + "\n"
+ "Your Password Change Link\n" + link + "?id=" + encrypted
+ "\n Click on the above link to Reset your Password";
String emailSubjectTxt = "Change Password Link";
String emailFromAddress = "abc@gmail.com";
String receipentList = emailText;
try {
MailUtility smtpMailSender = new MailUtility();
smtpMailSender.postMail(receipentList, emailSubjectTxt,emailMsgTxt, emailFromAddress);
} catch (MessagingException messagingException) {}
return ss;
}
MailUtility类
public class MailUtility {
public String postMail(String recipients, String subject,
String message, String from) throws MessagingException {
一些代码...... }
我已经以加密形式发送emailId,但我不知道如何保存解密密钥以及如何在一次使用和48小时后过期链接。

所以加密和解密的问题
以下代码将帮助您
注意服务器和客户端上的Constants.GWT_DES_KEY相同
例如:
private final static byte [] GWT_DES_KEY = new byte [] { -110,121,-65,22,-60,61,-22,-60,21,-122,41,-89,-89,-68,-8, 41,-119,-51,-12,-36,19,-8,-17,47 };
在服务器上:
TripleDesCipher cipher = new TripleDesCipher();
cipher.setKey(Constants.GWT_DES_KEY);
try {
enc = cipher.encrypt(String.valueOf(value));
} catch (DataLengthException e1) {
e1.printStackTrace();
} catch (IllegalStateException e1) {
e1.printStackTrace();
} catch (InvalidCipherTextException e1) {
e1.printStackTrace();
}
On the client, make sure you inherit the module:
<inherits name='com.googlecode.gwt.crypto.Crypto'/>
Then:
TripleDesCipher cipher = new TripleDesCipher();
cipher.setKey(Constants.GWT_DES_KEY);
String dec ="";
try {
dec = cipher.decrypt(enc);
} catch (DataLengthException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (InvalidCipherTextException e) {
e.printStackTrace();
}
