home.html：

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <title>个人信息页面</title></head><body><p>个人信息页面</p> </body></html>

只有返回一串字符串

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <title>登录页面</title></head><body> <p>登录页面</p> <form action="/login/" method="post">  {% csrf_token %}  <p>    账号：    <input type="text" name="user">  </p>  <p>    密码：    <input type="text" name="pwd">  </p>  <p>    <input type="submit" value="登录">  </p></form></body></html>

要考虑加上 csrf_token，不然会 403

from django.shortcuts import render, redirectfrom app01 import modelsdef login(request):  if request.method == "POST":    username = request.POST.get("user")    password = request.POST.get("pwd")    if username == "admin" and password == "admin":      rep = redirect("/home/") # 得到一个响应对象      rep.set_cookie("login", "success") # 设置 cookie      return rep  return render(request, "login.html")

set_cookie() 中的第一个参数为 key，第二个参数为 value

home 函数：

from django.shortcuts import render, redirectfrom app01 import models def home(request):  ret = request.COOKIES.get("login") # 获取 cookie 的 value  if ret == "success":    # cookie 验证成功    return render(request, "home.html")  else:    return redirect("/login/")

输入账号、密码：admin，cookie 验证成功

给 cookie 加盐：

from django.shortcuts import render, redirectfrom app01 import modelsdef login(request):  if request.method == "POST":    username = request.POST.get("user")    password = request.POST.get("pwd")    if username == "admin" and password == "admin":      rep = redirect("/home/") # 得到一个响应对象      # rep.set_cookie("login", "success") # 设置 cookie      rep.set_signed_cookie("login", "success", salt="whoami") # 设置 cookie 并加盐      return rep  return render(request, "login.html")

home 函数：

from django.shortcuts import render, redirectfrom app01 import modelsdef home(request):  # ret = request.COOKIES.get("login") # 获取 cookie 的 value  ret = request.get_signed_cookie("login", salt="whoami") # 获取加盐后 cookie 的 value  if ret == "success":    # cookie 验证成功    return render(request, "home.html")  else:    return redirect("/login/")

输入账号、密码：admin，cookie 验证成功
