1、Web.config配置上system.web节点下加入以下配置

<system.web>
    <authentication mode="Forms">
      <forms name=".wechat" loginUrl="url" timeout="30" protection="All" defaultUrl="/index.html" />
    </authentication>
    <httpCookies httpOnlyCookies="true" requireSSL="true" />
  </system.web>

2、上代码

using Newtonsoft.Json;
using System;
using System.Security.Principal;
using System.Web;
using System.Web.Http;
using System.Web.Security;
 
namespace KMHC.CTMS.DrugStore.Controllers
{
    public class BaseApiController : ApiController
    {
        protected void SignIn(dynamic user)
        {
            if (user == null)
                return;
            var httpContext = HttpContext.Current;
 
            var version = 1;
            var name = user.OpenId;
            var now = DateTime.Now.ToLocalTime();
            var expiration = now.Add(TimeSpan.FromDays(30));
            var isPersistent = true;
            var userData = JsonConvert.SerializeObject(user);
 
            var ticket = new FormsAuthenticationTicket(version, name, now, expiration, isPersistent, userData, FormsAuthentication.FormsCookiePath);
 
            var encryptedTicket = FormsAuthentication.Encrypt(ticket);
 
            var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket)
            {
                HttpOnly = true,
                Secure = FormsAuthentication.RequireSSL,
                Path = FormsAuthentication.FormsCookiePath
            };
            cookie.Expires = ticket.Expiration;
            if (FormsAuthentication.CookieDomain != null)
            {
                cookie.Domain = FormsAuthentication.CookieDomain;
            }
 
            var url = HttpContext.Current.Request.Url.ToString();
            if (!string.IsNullOrEmpty(url) && url.StartsWith("https"))
            {
                cookie.Secure = true;
            }
 
            httpContext.Response.Cookies.Add(cookie);
 
            httpContext.User = new GenericPrincipal(new FormsIdentity(ticket), new string[] { "Wechat" });
        }
 
        protected string OpenId
        {
            get
            {
                return this.User.Identity.Name;
            }
        }
 
        protected bool IsAuthenticated
        {
            get
            {
                return this.User.Identity.IsAuthenticated;
            }
        }
 
        protected dynamic UserInfo {
            get {
                var identity = (FormsIdentity)HttpContext.Current.User.Identity;
                var user = JsonConvert.DeserializeObject<dynamic>(identity.Ticket.UserData);
                return user;
            }
        }
    }
}

3、默认地址获取

//index.html  <forms name=".wechat" loginUrl="url" timeout="30" protection="All" defaultUrl="/index.html" />

var defaultUrl= FormsAuthentication.DefaultUrl;
