c#中token怎么用

这篇文章主要介绍了c#中token怎么用，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

token的存在意义

这是我初略了解的token的存在意义

• 用户使用用户名密码来请求服务器

• 服务器进行验证用户的信息

• 服务器通过验证发送给用户一个token

• 客户端存储token，并在每次请求时附送上这个token值

• 服务端验证token值，并返回数据

使用方法

先安装一个JWT，注意NetFramework的版本

创建一个工具类TokenInfo.cs

using JWT;using JWT.Algorithms;using JWT.Serializers;using System;using System.Collections.Generic;using System.Web;using System.Web.Script.Serialization;namespace ProjectLYG.Common{    public class TokenInfo    {        public TokenInfo()        {            UserName = "j";            Pwd = "123456";        }        public string UserName { get; set; }        public string Pwd { get; set; }    }    public class TokenHelper    {        public static string SecretKey = "bqsid123k12s0h2d3uhf493fh02hdd102h9s3h48ff";//这个服务端加密秘钥 属于私钥        private static JavaScriptSerializer myJson = new JavaScriptSerializer();        /// 
        /// 生成Token        /// 
        ///         ///         public static string GenToken(TokenInfo M)        {            var payload = new Dictionary            {                {"UserName", M.UserName},//用于存放当前登录人账户信息                {"UserPwd", M.Pwd}//用于存放当前登录人登录密码信息            };            IJwtAlgorithm algorithm = new HMACSHA256Algorithm();            IJsonSerializer serializer = new JsonNetSerializer();            IBase64UrlEncoder urlEncoder = new JwtBase64UrlEncoder();            IJwtEncoder encoder = new JwtEncoder(algorithm, serializer, urlEncoder);            return encoder.Encode(payload, SecretKey);        }        /// 
        /// 验证Token        /// 
        ///         public static string DecodeToken()        {            //获取request中的token            string token = HttpContext.Current.Request.Headers["Authorization"];            //去掉前面的Bearer            if (token != null && token.StartsWith("Bearer"))                token = token.Substring("Bearer ".Length).Trim();            try            {                var json = GetTokenJson(token);                TokenInfo info = myJson.Deserialize(json);                return "Token is true";            }            catch (TokenExpiredException)            {                return "Token has expired";            }            catch (SignatureVerificationException)            {                return "Token has invalid signature";            }        }        public static string GetTokenJson(string token)        {            try            {                IJsonSerializer serializer = new JsonNetSerializer();                IDateTimeProvider provider = new UtcDateTimeProvider();                IJwtValidator validator = new JwtValidator(serializer, provider);                IBase64UrlEncoder urlEncoder = new JwtBase64UrlEncoder();                IJwtDecoder decoder = new JwtDecoder(serializer, validator, urlEncoder);                var json = decoder.Decode(token, SecretKey, verify: true);                return json;            }            catch (Exception)            {                throw;            }        }    }}

使用方法

                 //生成Token                TokenInfo tokenInfo = new TokenInfo();                tokenInfo.Pwd = password;                tokenInfo.UserName = tel;                string token = TokenHelper.GenToken(tokenInfo);                ........                 //token验证                string tokenInfo = TokenHelper.DecodeToken();                ........

工具类已将返回的Request的token值提取出，无须传值
