1.需要在startup.cs中添加cookie的服务
services.Configure<CookiePolicyOptions>(option =>{ option.CheckConsentNeeded=ContextBoundObject=>true; option.MinimumSameSitePolicy=SameSiteMode.None; }); //添加cookie的服务
图示:
2.在startup.cs中启动服务
app.UseCookiePolicy(); //启用cookie服务
图示:
startup.cs中添加的引用:
using System; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks; using Microsoft.AspNetCore.Builder; using Microsoft.AspNetCore.Hosting; using Microsoft.AspNetCore.Http; using Microsoft.Extensions.DependencyInjection; //参数验证,路由的参数验证配置 using Microsoft.AspNetCore.Routing; using Microsoft.AspNetCore.Routing.Constraints; //mysql基础配置引用 using Online.Examination.Web.Repositories; using Online.Examination.Web.Controllers; using Online.Examination.Web.Repositories.DBBase;

3.在控制层使用Append方法向客户端添加cookie
//cookie的引用 需要引用这三个包
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.CookiePolicy;
using Microsoft.AspNetCore.Http.Features;
图示:
4.最后一步:很重要 如果服务器要想客户端存储cookie,客户端需要向服务器发送第一次请求,请求允许使用cookie
所以需要在控制层中写入方法,这个方法只需要请求一次,就可以向客户端存储cookie了
5.js代码示例
$(function() { $.post("/login/OkCookie", function() {}) //如果使用cookie,客户端必须向服务端发送一次请求//// }) function login() { $(".error").text(""); var uname = $("input[name=‘name‘]").val(); var pwd = $("input[name=‘pwd‘]").val(); var type = $("input[name=‘login_type‘]:checked").val(); if (uname == "" || pwd == "") return false; $.post("/login/login", { "uname": uname, "pwd": pwd, "type": type }, function(msg) { if (msg.message == "success") { window.location.href = "index.html?id=" + msg.users.name; } else { $(".error").text("密码或账号错误"); } }) }
图示:
6.关于cookie其他的使用方法
代码:
protected void DeleteCookies(string key) //删除指定的cookie { HttpContext.Response.Cookies.Delete(key); } protected string GetCookies(string key) //获取指定的cookie { HttpContext.Request.Cookies.TryGetValue(key, out string value); if (string.IsNullOrEmpty(value)) value = string.Empty; return value; }
