Servlet doPost方法

Question

This is a simple html page: 这是一个简单的html页面：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="ISO-8859-1">
            <title>GET_POST</title>
    </head>
    <body>

       <h5> Insert username and password  </h5>

       <form action ="./get_Post" method ="post">
           username: <br>
           <input type = "text" name = "username">
           <br>
           password:<br>
           <input type = "password" name ="password">
           <br><br>
           <input type = "submit" value = "LOGIN">
       </form>
    </body>
</html>

The form of this html page called the servlet has /get_Post as url-mapping in web.xml. 此html页面的形式称为servlet，在web.xml中具有/ get_Post作为url映射。

Now, this is doPost method of the servlet: 现在，这是servlet的doPost方法：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String password = request.getParameter("password");
    PrintWriter out = response.getWriter();
    out.println(password);
}

I expected null pointer exception, and instead the servlet gets the password I put in the html form. 我预计会出现空指针异常，而servlet会获取我以html形式输入的密码。 What can I do to make private password information? 如何制作私人密码信息？

If you're worried about security you need to enable SSL. 如果您担心安全性，则需要启用SSL。 For tomcat; 对于雄猫 first create a keystore and then add an SSL connector description to server.xml 首先创建密钥库，然后将SSL连接器描述添加到server.xml

<Connector port="8443" scheme="https" secure="true" SSLEnabled="true"
   keystoreFile="somekeystore" sslProtocol="TLS"
   keystorePass="pwd" />

Then forward login requests to HTTPS page and redirect to HTTP after authorization. 然后将登录请求转发到HTTPS页面，并在授权后重定向到HTTP。
