+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+# gtoken
+
+#### 介绍
+基于gf框架的token插件，通过服务端验证方式实现token认证；
+
+1. 支持单机gcache模式
+2. 支持简单token认证
+3. 框架使用简单，只需要设置登录验证方法以及登录、登出、拦截路径即可；
+
+#### 安装教程
+
+gopath模式: `go get https://gitee.com/goflyfox/gtoken`
+
+或者 使用go.mod添加 :`require gitee.com/goflyfox/gtoken last`
+
+#### 使用说明
+
+只需要配置登录路径、登出路径、拦截路径以及登录校验实现即可
+
+```go
+	// 启动gtoken
+	gtoken := &gtoken.GfToken{
+		LoginPath:       "/login",
+		LoginBeforeFunc: loginFunc,
+		LogoutPath:      "/user/logout",
+		AuthPaths:       g.SliceStr{"/user/*", "/system/*"},
+	}
+	gtoken.Start()
+```
+
+登录方法实现
+
+```go
+func Login(r *ghttp.Request) (string, interface{}) {
+	username := r.GetPostString("username")
+	passwd := r.GetPostString("passwd")
+
+	// TODO 进行登录校验
+
+	return username, ""
+}
+```
+
+#### 逻辑测试
+
+可运行api_test.go进行测试并查看结果；验证逻辑说明：
+
+1. 访问用户信息，提示未携带token
+2. 登录后，携带token访问正常
+3. 登出成功
+4. 携带之前token访问，提示未登录
+
+```json
+--- PASS: TestSystemUser (0.00s)
+    api_test.go:43: 1. not login and visit user
+    api_test.go:50: {"code":-1,"data":"","msg":"query token fail"}
+    api_test.go:63: 2. execute login and visit user
+    api_test.go:66: {"code":0,"msg":"success","data":"system user"}
+    api_test.go:72: 3. execute logout
+    api_test.go:75: {"code":0,"msg":"success","data":"logout success"}
+    api_test.go:81: 4. visit user
+    api_test.go:86: {"code":-1,"msg":"login timeout or not login","data":""}
+```
