Python Django Cookie 简单用法解析
人气:0home.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
login.html:
<!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
login 函数:
from django.shortcuts import render, redirect from app01 import models def 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, redirect from 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:
login 函数:
from django.shortcuts import render, redirect from app01 import models def 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, redirect from app01 import models def 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
