通过Gin框架对接阿里云SLS日志服务，查询服务日志

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")}
