需求
自己输入框搜索，跳转到百度页面搜索。
思路
- jsp实现搜索框，传递搜索内容到servlet
- servlet获得搜索内容重定向传参到百度
- 随便测试一下发现百度搜索关键词为wd=
具体可参考百度搜索URL参数含义
代码实现

import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@WebServlet(name = "SearchServlet",urlPatterns = "/search")
public class SearchServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String searchContent = request.getParameter("searchContent");
response.sendRedirect("https://www.baidu.com/s?wd="+searchContent);
}
}
实现效果
