十月二十四日

最近晚上都凉起来了,实在是懒,一到晚上就犯困躺在床上就不想动。但还是一直心心念着,这次就说说乱码问题,首先就是两行代码

          request.setCharacterEncoding("UTF-8");
//设置响应的MIME类型,可以指定字符编码,即响应体的字符编码
      response.setContentType("text/html;charset=UTF-8");

这个是关于请求与响应的设置字符编码,主要是在上传服务器器是不同的编码的不同导致,好像是新版本的服务器都已经更改了这个,建议大家用新的,否则就需要添加上面的代码。

其实还要关于HTTP协议的相关内容,建议大家能够好好学习了解这些。

package comServlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import java.util.Map;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class RegisterServlet extends HttpServlet {
//    private static final long serialVersionUID = 1L;


    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setCharacterEncoding("UTf-8");
//        response.setCharacterEncoding("UTF-8");
        //设置响应的MIME类型,可以指定字符编码,即响应体的字符编码
        response.setContentType("text/html;charset=UTF-8");
        String name = request.getParameter("name");
        String possword = request.getParameter("possword");
        System.out.println("name = "+ name);
        System.out.println("possword = "+ possword);
        //输出到控制台
        PrintWriter out = response.getWriter();
        out.println("name = "+ name);
        out.println("possword = " + possword);

        
        
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <form action="registerServlet" method="post">
        name:<input type="text" name="name"><br>
        possword:<input type="password" name="possword"><br>
        <button>提交</button>
    </form>
</body>
</html>

 

 这个是我写的一个简单的用户,密码还有在web返回显示输入的内容。
