A golang library to use cloudflare speed test function. use it in your own golang project.
I want to use cloudflare cdn ip speed test in my own project. there is a command-line tool called CloudflareSpeedTest, but if you want to use in your own project,you need wrap it as a bash call. so, here is the project.
# in terminal
go get github.com/fireinrain/cf-speedtester@v1.0.6
# in your project
import (
"github.com/fireinrain/cf-speedtester"
)
client := cf_speedtester.NewCFSpeedTestClient(
config.WithMaxDelay(300*time.Millisecond),
config.WithMinSpeed(2),
config.WithTestCount(5),
)
client.DoSpeedTest()
results := client.SpeedResults
fmt.Println(results)
client := cf_speedtester.NewCFSpeedTestClient(
config.WithMaxDelay(300*time.Millisecond),
config.WithMinSpeed(2),
config.WithTestCount(5),
)
client.DoSpeedTest()
results := client.SpeedResults
fmt.Println(results)
client.ExportToCSV("results.csv")
client := NewCFSpeedTestClient(
config.WithMaxDelay(300*time.Millisecond),
config.WithMinSpeed(2),
config.WithTestCount(5),
config.WithDownloadUrl("https://youself-download-url.com"),
)
result := client.DoSpeedTestForResult()
fmt.Println(result)
//replace ips that you find proxied for cloudflare cdn
var ips = []string{
"193.122.125.193",
"193.122.119.93",

}
var ipList []*net.IPAddr
for _, ip := range ips {
addr := utils.IPStrToIPAddr(ip)
ipList = append(ipList, addr)
}
client := cf_speedtester.NewCFSpeedTestClient(
config.WithMaxDelay(300*time.Millisecond),
config.WithMinSpeed(2),
config.WithTestCount(1),
config.WithIPListForTest(ipList),
)
result := client.DoSpeedTestForResult()
fmt.Println(result)
if you find you get the cloudflare ip is banned in china with this library, take it easy and here is the solution.
//develop yourself ip ban check function, and inject to the config
func YouselfIPBanChecker(some any) any{
//do you check logic
//notice: you need convert any to handler.PingDelaySet
//and with PingDelaySet,do your check logic and return
//checked PingDelaySet
return some
}
//here is an example of a IPBanChecker
func DoIPBanCheck(someData any) any {
var result []handler.CloudflareIPData
//转型
if pingDelaySetValue, ok := someData.(handler.PingDelaySet); ok {
log.Println("Convert someData to PingDelaySet type success,size is :", len(pingDelaySetValue))
//do ip banned check
//DoIPBanCheckInPool if self write check logic, replaced with your check logic
checkerResults := DoIPBanCheckInPool(pingDelaySetValue, 3)
for _, checkerResult := range checkerResults {
if checkerResult.IsBanned == false {
result = append(result, *checkerResult.CheckIPAddr)
}
}
log.Println("Do ip banned check finished, result size is :", len(result))
return result
} else {
log.Println("Convert someData to PingDelaySet type failed :", someData)
}
return someData
}

- download speed always 0? you should change the custom download url, and have a test.
here are some download speed test urls provided by PencilNavigator, thanks for your efforts.
- CloudflareSpeedTest,Thanks very much !
- Jetbrains Goland IDE, Thanks very much !
