【Go从入门到实战】学习笔记，从零开始学Go、Gin框架，基本语法包括26个Demo，Gin框架包括：Gin自定义路由配置

## 项目介绍 [Gin 日志记录](https://github.com/xinliangnote/Go/blob/master/01-Gin框架/03-日志记录.md) ## 修改日志 2019-07-30 优化了 logger.go，日志新增了返回数据，见[最新代码包](https://github.com/xinliangnote/Go/tree/master/01-Gin框架/codes/05-自定义错误处理)。 ## 配置 ``` // 日志记录到文件 func LoggerToFile() gin.HandlerFunc { logFilePath := config.Log_FILE_PATH logFileName := config.LOG_FILE_NAME //日志文件 fileName := path.Join(logFilePath, logFileName) //写入文件 src, err := os.OpenFile(fileName, os.O_APPEND|os.O_WRONLY, os.ModeAppend) if err != nil { fmt.Println("err", err) } //实例化 logger := logrus.New() //设置输出 logger.Out = src //设置日志级别 logger.SetLevel(logrus.DebugLevel) //设置日志格式 logger.SetFormatter(&logrus.TextFormatter{}) return func(c *gin.Context) { // 开始时间 startTime := time.Now() // 处理请求 c.Next() // 结束时间 endTime := time.Now() // 执行时间 latencyTime := endTime.Sub(startTime) // 请求方式 reqMethod := c.Request.Method // 请求路由 reqUri := c.Request.RequestURI // 状态码 statusCode := c.Writer.Status() // 请求IP clientIP := c.ClientIP() // 日志格式 logger.Infof("| %3d | %13v | %15s | %s | %s |", statusCode, latencyTime, clientIP, reqMethod, reqUri, ) } } ``` ## 运行 **下载源码后，请先执行 `dep ensure` 下载依赖包！** ## 效果图 ``` time="2019-07-17T22:10:45+08:00" level=info msg="| 200 | 27.698µs | ::1 | GET | /v1/product/add?name=a&price=10 |" time="2019-07-17T22:10:46+08:00" level=info msg="| 200 | 27.239µs | ::1 | GET | /v1/product/add?name=a&price=10 |" ``` ``` time="2019-07-17 22:15:57" level=info msg="| 200 | 185.027µs | ::1 | GET | /v1/product/add?name=a&price=10 |" time="2019-07-17 22:15:58" level=info msg="| 200 | 56.989µs | ::1 | GET | /v1/product/add?name=a&price=10 |" ``` ``` {"level":"info","msg":"| 200 | 24.78µs | ::1 | GET | /v1/product/add?name=a\u0026price=10 |","time":"2019-07-17 22:23:55"} {"level":"info","msg":"| 200 | 26.946µs | ::1 | GET | /v1/product/add?name=a\u0026price=10 |","time":"2019-07-17 22:23:56"} ``` ``` {"client_ip":"::1","latency_time":26681,"level":"info","msg":"","req_method":"GET","req_uri":"/v1/product/add?name=a\u0026price=10","status_code":200,"time":"2019-07-17 22:37:54"} {"client_ip":"::1","latency_time":24315,"level":"info","msg":"","req_method":"GET","req_uri":"/v1/product/add?name=a\u0026price=10","status_code":200,"time":"2019-07-17 22:37:55"} ```
