理论上，当
AMPByExample服务器收到登录页面的 POST 请求时，如果凭据正确，它会将请求重定向到的 URLreturnURL并添加参数success = true。一旦完成，AMP执行时间最终可以授权页面。
登录页面如下：
登录.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Login Page</title>
</head>
<body>
<form method="post" action="loginauthorization">
Correo Electronico: <input type="text" name="correo"><br>
Contraseña: <input type="password" name="clave"><br>
<input name="returnurl" type="hidden" value="https://cdn.ampproject.org/v0/amp-login-done-0.1.html?url=https%3A%2F%2Fampbyexample.com%2Fplayground%2F">
<input type="submit" value="Ingresar">
</form>
</body>
</html>如您所见，returnurl它是相同的登录 URL，AmpByExample但它不起作用。
我已经尝试通过以下方式制作自己的网址：
<input name="returnurl" type="hidden" value="https://cdn.ampproject.org/v0/amp-login-done-0.1.html?url=http%3A%2F%2Flocalhost%3A8084%2Fmypage%2Fpanel.jsp">它也不起作用。
在loginauthorization.java我收到的 servlet 中returnurl，我添加了# success = true（假设我必须验证用户名和密码，但我想先让它工作）。
登录授权.java：
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.*;
public class loginauthorization extends HttpServlet {
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try{
response.setContentType("text/html");
//I get the parameters
String email = request.getParameter("correo");
String password = request.getParameter("clave");
String url = request.getParameter("pageurl");
int ridini = url.indexOf("rid=")+4;
int ridend = url.indexOf("&url=");
String rid = url.substring(ridini, ridend);
String returnurl = request.getParameter("returnurl");
//assuming that the username and password are correct, add to the returnurl success true
returnurl= returnurl + "#success=true";
//create a session
HttpSession session=request.getSession();
session.setAttribute("umail",email);
session.setAttribute("upass",password);
session.setAttribute("rid",rid);
session.setAttribute("returnurl",returnurl);
//redirect after login with the success = true
response.sendRedirect(returnurl);
}catch(Exception exp){
System.out.println(exp);
}
}
}面板配置如下：
面板.jsp
<script id="amp-access" type="application/json">
{
"authorization": "http://localhost:8084/mypage/jsonauthorization",
"noPingback": "true",
"login": {
"sign-in": "/mypage/login.jsp?rid=READER_ID&url=CANONICAL_URL&return=RETURN_URL",
"sign-out": "/mypage/endsession"
},
"authorizationFallbackResponse": {
"loggedIn": false
},
"type": "server"
}
</script>jsonauthorization印刷品{"loggedIn": true}或{"loggedIn": false}：_
jsonauthorization.java
import java.io.*;
import javax.servlet.http.*;
public class jsonauthorization extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response){
try{
response.setContentType("application/json");
response.setHeader("AMP-Access-Control-Allow-Source-Origin", "http://localhost:8084/mypage");
PrintWriter pwriter = response.getWriter();
HttpSession session=request.getSession(false);
if(session != null){
String email=(String)session.getAttribute("umail");
if(email==null){
session.invalidate();
pwriter.print("{\"loggedIn\":false}");
}else{
String rid;
rid = (String) session.getAttribute("rid");
Cookie AmpCookie = new Cookie("authorized",rid);
AmpCookie.setPath("/");
AmpCookie.setDomain("/mypage");
response.addCookie(AmpCookie);
pwriter.print("{\"loggedIn\":true}");
}
}else{
pwriter.print("{\"loggedIn\":false}");
}
pwriter.close();
}catch(Exception exp){
System.out.println(exp);
}
}
}我很感激答案，如果错误不在
returnurl请告诉我在哪里：P
