这是我目前的JSP代码：response.sendRedirect是在JSP

<%@ 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>

这里我用jsp:forward page="index.jsp"重定向到index.jsp页面。那么，如果我想用response.sendRedirect("index.jsp")？我该如何继续？

我尝试这样做：

<% 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>

但失败了。请帮忙！谢谢！！

回答：

response.sendRedirect()是Java代码不是一个标签，所以你应该不键入它之前关闭scriptlet标记，它不是由<开头且>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 
} 
%>

以上是 response.sendRedirect是在JSP 的全部内容， 来源链接： utcz.com/qa/259955.html
