[英]response.sendRedirect in JSP
这是我当前的 JSP 代码:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<jsp:useBean id="user" class= "uts.wsd.User" scope="session" ></jsp:useBean>
<%
String name = request.getParameter("name");
String email = request.getParameter("email");
String password = request.getParameter("password");
String gender = request.getParameter("gender");
String color = request.getParameter("favcol");
user.setName(name);
user.setEmail(email);
user.setPassword(password);
user.setGender(gender);
user.setFavouriteColour(color);
%>
<body style="background: <%= color %>;">
<% if (request.getParameter("tos") == null ) {%>
<p>
Sorry, you must agree to the Terms of Service.</p>
<p>Click <a href="register.jsp" > here </a> to go back.
</p>
<%} else { %>
<jsp:forward page="index.jsp" />
<% } %>
</html>
这里我使用jsp:forward page="index.jsp"
重定向到 index.jsp 页面。 那么,如果我想使用response.sendRedirect("index.jsp")
呢? 我该如何继续?
我试过这个:
<% if (request.getParameter("tos") == null ) {%>
<p>
Sorry, you must agree to the Terms of Service.</p>
<p>Click <a href="register.jsp" > here </a> to go back.
</p>
<%} else { %>
<response.sendRedirect("index.jsp")>
<% } %>
</html>
但它失败了。 请帮忙! 谢谢!!
response.sendRedirect()
是Java代码不是一个标签,所以你不应该键入它接近scriptlet标记之前,它是不是在前面加<
与关闭>
...它只是Java代码:
<%
}
else
{
response.sendRedirect("index.jsp");
return; //this is to redirect immediately so it doesn't
//run any code below this point before redirecting
}
%>
