CDN相关功能

在使用CDN相关功能之前，需要构建CdnManager对象：

  1. mac := qbox.NewMac(accessKey, secretKey)
  2. cdnManager := cdn.NewCdnManager(mac)

文件刷新

  1. //刷新链接，单次请求链接不可以超过100个，如果超过，请分批发送请求
  2. urlsToRefresh := []string{
  3.     "http://if-pbl.qiniudn.com/qiniu.png",
  4.     "http://if-pbl.qiniudn.com/github.png",
  5. }
  7. ret, err := cdnManager.RefreshUrls(urlsToRefresh)
  8. if err != nil {
  9.     fmt.Println(err)
  10.     return
  11. }
  12. fmt.Println(ret.Code)
  13. fmt.Println(ret.RequestID)

目录刷新

  1. // 刷新目录，刷新目录需要联系七牛技术支持开通权限
  2. // 单次请求链接不可以超过10个，如果超过，请分批发送请求
  3. dirsToRefresh := []string{
  4.     "http://if-pbl.qiniudn.com/images/",
  5.     "http://if-pbl.qiniudn.com/static/",
  6. }
  8. ret, err := cdnManager.RefreshDirs(dirsToRefresh)
  9. if err != nil {
  10.     fmt.Println(err)
  11.     return
  12. }
  13. fmt.Println(ret.Code)
  14. fmt.Println(ret.RequestID)
  15. fmt.Println(ret.Error)

文件预取

  1. // 预取链接，单次请求链接不可以超过100个，如果超过，请分批发送请求
  2. urlsToPrefetch := []string{
  3.     "http://if-pbl.qiniudn.com/qiniu.png",
  4.     "http://if-pbl.qiniudn.com/github.png",
  5. }
  7. ret, err := cdnManager.PrefetchUrls(urlsToPrefetch)
  8. if err != nil {
  9.     fmt.Println(err)
  10.     return
  11. }
  12. fmt.Println(ret.Code)
  13. fmt.Println(ret.RequestID)

获取域名流量

  1. domains := []string{
  2.     "if-pbl.qiniudn.com",
  3.     "qdisk.qiniudn.com",
  4. }
  5. startDate := "2017-07-30"
  6. endDate := "2017-07-31"
  7. granularity := "day"
  9. data, err := cdnManager.GetFluxData(startDate, endDate, granularity, domains)
  10. if err != nil {
  11.     fmt.Println(err)
  12.     return
  13. }
  14. fmt.Printf("%v\n", data)

获取域名带宽

  1. domains := []string{
  2.     "if-pbl.qiniudn.com",
  3.     "qdisk.qiniudn.com",
  4. }
  5. startDate := "2017-07-30"
  6. endDate := "2017-07-31"
  7. granularity := "day"
  9. data, err := cdnManager.GetBandwidthData(startDate, endDate, granularity, domains)
  10. if err != nil {
  11.     fmt.Println(err)
  12.     return
  13. }
  14. fmt.Printf("%v\n", data)

获取日志下载链接

  1. domains := []string{
  2.     "if-pbl.qiniudn.com",
  3.     "qdisk.qiniudn.com",
  4. }
  6. day := "2017-07-30"
  8. ret, err := cdnManager.GetCdnLogList(day, domains)
  9. if err != nil {
  10.     fmt.Println(err)
  11.     return
  12. }
  14. domainLogs := ret.Data
  15. for domain, logs := range domainLogs {
  16.     fmt.Println(domain)
  17.     for _, item := range logs {
  18.         fmt.Println(item.Name, item.URL, item.Size, item.ModifiedTime)
  19.     }
  20. }

构建时间戳防盗链访问链接

具体算法可以参考：时间戳防盗链

  1. urlStr := "http://img.abc.com/test.jpg"
  2. cryptKey := "abc123"
  3. deadline := time.Now().Add(time.Second * 3600).Unix()
  4. accessUrl, err := cdn.CreateTimestampAntileechURL(urlStr, cryptKey, deadline)
  5. if err != nil {
  6.     fmt.Println(err)
  7.     return
  8. }
  9. fmt.Println(accessUrl)
