通过Gin框架对接阿里云SLS日志服务，查询服务日志，你学会了吗？

package main


import (
  "fmt"
  "github.com/aliyun/aliyun-log-go-sdk"
  "github.com/gin-gonic/gin"
  "net/http"
  "time"
)


func main() {
  router := gin.Default()


  router.GET("/download-logs", func(c *gin.Context) {
    // 地区
    endpoint := "cn-beijing.log.aliyuncs.com"
    // key
    accessKeyID := "LTAI5tShzYy1VMGR17H"
    // 密钥
    accessKeySecret := "QELEeTCudJHYhYY3mpuD"


    provider := sls.NewStaticCredentialsProvider(accessKeyID, accessKeySecret, "")
    client := sls.CreateNormalInterfaceV2(endpoint, provider)


    ProjectName := "dean"
    LogStoreName := "nginx"


    logstore, err := client.GetLogStore(ProjectName, LogStoreName)
    if err != nil {
      fmt.Println("出现报错了")
      panic(err)
    }
    fmt.Println("get logstore successfully:", logstore.Name)


    // 设置查询的时间范围
    fromTime := time.Now().Unix() - (60 * 60 * 24) // 24小时之前
    toTime := time.Now().Unix()                    // 当前时间


    // 设置查询的参数
    query := "*"
    line := int64(100) // 每页日志条数
    offset := int64(0) // 偏移量


    // 获取日志
    resp, err := logstore.GetLogs("", fromTime, toTime, query, line, offset, false)
    if err != nil {
      fmt.Println(err)
      c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to get logs"})
      return
    }
    logs := resp.Logs


    // 将所有日志转换为JSON格式返回
    c.JSON(http.StatusOK, logs)


    //// 设置文件名（可以根据需要自定义）
    //filename := "access_log_" + time.Now().Format("20060102150405") + ".txt"
    //
    //// 设置HTTP头信息，指示这是一个文件下载响应
    //c.Header("Content-Disposition", "attachment; filename=\""+filename+"\"")
    //c.Header("Content-Type", "text/plain")
    //
    //// 写入文件内容
    //c.String(http.StatusOK, logs)


    // 设置下载相关的头部信息
    c.Header("Content-Description", "File Transfer")
    c.Header("Content-Disposition", "attachment; filename=logs.txt")
    c.Header("Content-Type", "application/octet-stream")


    // 将日志内容写入响应体
    for _, log := range resp.Logs {
      c.Writer.Write([]byte(fmt.Sprintf("%v\n", log)))
    }


  })


  router.Run(":8080")
}
