+# 刷新Token
+### 在Params创建文件RefreshToken.cs
+```
+namespace ApiTest.Api.Params
+{
+ public class RefreshTokenDTO
+ {
+ public string Token { get; set; }
+ public string refreshToken { get; set; }
+ }
+}
+```
+
+### UsersController.cs加入新代码
+```
+[AllowAnonymous]
+ [HttpPost, Route("refreshtoken")]
+ public dynamic RefreshToken(RefreshTokenDTO refresh)
+ {
+ var username = TokenHelper.ValidateToken(_tokenParameter, refresh);
+
+ if (string.IsNullOrEmpty(username))
+ {
+ return new { Code = 1002, Data = "", Msg = "token验证失败" };
+ }
+
+ var token = TokenHelper.GenerateToekn(_tokenParameter,username);
+ var refreshToken = "112358";
+
+ return new {
+ Code = 1000,
+ Data = new { Token = token, refreshToken = refreshToken },
+ Msg = "刷新token成功^_^"
+ };
+ }
+
+```
+
+### .http文件加入新代码
+```
+### 刷新重新获取token
+POST http://localhost:5000/users/refreshtoken HTTP/1.1
+Content-Type: application/json
+
+{
+ "token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoiYWRtaW4iLCJodHRwOi8vc2NoZW1hcy5taWNyb3NvZnQuY29tL3dzLzIwMDgvMDYvaWRlbnRpdHkvY2xhaW1zL3JvbGUiOiJhZG1pbiIsImV4cCI6MTYyNTczODExMywiaXNzIjoiemh1emh1In0.p93sueqGudKolh8CpPaXhMEGWpXzIsgp474JMsvXupU",
+ "refreshtoken":"113"
+}
+```
+
+效果如下：
+
+
+### 加入代码，消除过期时间设置成少于五分钟的时长，token生效问题
+```
+在生成Token时，我们把过期时间设置成少于五分钟的时长，比方3分钟。但这时，实测会发现，Token的过期失效了。
+
+为什么呢？
+
+TokenValidationParameters有一个属性叫ClockSkew，这个参数有个默认值是TimeSpan.FromMinutes(5)。
+
+这个参数的意义是：考虑到各个服务器之间的时间不一定完全同步，系统给了个5分钟的误差时间。
+
+这个误差时间导致的结果是：少于五分钟的过期时间，会在实际认证检查时被忽略。
+```
+
+
+
+### 当我们将刷新时间设置为两分钟时，过了两分钟他就会重新生成一个新的token，那么旧的token就不能用了！！！

+# .Net Core 审计日志
+```
+审计日志：
+维基百科： “审计跟踪（也叫审计日志）是与安全相关的按照时间顺序的记录，记录集或者记录源，它们提供了活动序列的文档证据，这些活动序列可以在任何时间影响一个特定的操作，步骤或其他”
+```
+### 作用
+```
+ 1、快速定位问题耗时及性能情况
+
+ 2、记录调用时环境信息：如浏览器、参数等
+```
+### 如何实现思路
+```
+获取调用接口方法时相关信息
+
+记录当前接口耗时情况
+
+保存审计日志信息到数据库中
+
+ 那么如何获取调用接口时相关信息呢？.Net Core中可以使用：过滤器、拦截器 实现。
+```
+
+### 在Entity下创建AuditInfo
