[英]How to configure basic authentication in tomcat 8.5? HTTP Error 401
[英]Http status 401 This request requires HTTP authentication (). in tomcat 6
我已經開發了一個Web應用程序
如果我在tomcat 6中運行該應用程序,則要求輸入用戶名和密碼,但經過3次嘗試后,它將顯示 web.xml文檔是
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<realm-name>Authentication required</realm-name>
</login-config>
<security-role>

</web-app>
我想獲取遠程用戶的用戶名和密碼,我該怎么辦? 這是我的servlet代碼
package com.src;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.tomcat.util.buf.Base64;
public class remoteSample extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public remoteSample() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.setContentType("text/html;charset=UTF-8");
System.out.println("login info:"+request.getRemoteUser());
System.out.println("Authentication type:"+request.getAuthType());
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
}
我應該在服務器的tomcat-server.xml和web.xml中進行更改嗎?
