请求curl返回的各项时间为 0

[oslet]

环境: ubuntu 16.04 x86_64
package main

import (
curl "github.com/andelf/go-curl"
"fmt"
)

func main() {
	easy := curl.EasyInit()
	defer easy.Cleanup()
	if easy != nil {
		easy.Setopt(curl.OPT_URL, "http://www.oslet.net/")
		fmt.Println(easy.Getinfo(curl.INFO_RESPONSE_CODE))
		fmt.Println(easy.Getinfo(curl.INFO_TOTAL_TIME))
		fmt.Println(easy.Getinfo(curl.INFO_APPCONNECT_TIME))
		fmt.Println(easy.Getinfo(curl.INFO_STARTTRANSFER_TIME))
		fmt.Println(easy.Getinfo(curl.INFO_REDIRECT_TIME))
		fmt.Println(easy.Getinfo(curl.INFO_NAMELOOKUP_TIME))
		fmt.Println(easy.Getinfo(curl.INFO_PRETRANSFER_TIME))
		fmt.Println(easy.Getinfo(curl.INFO_CONNECT_TIME))
		
		ver := curl.VersionInfo(curl.VERSION_NOW)
		fmt.Printf("VersionInfo: Age: %d, Version:%s, Host:%s, Features:%d, SslVer: %s, LibzV: %s, ssh: %s\n",
			ver.Age, ver.Version, ver.Host, ver.Features, ver.SslVersion, ver.LibzVersion, ver.LibsshVersion)
	}
}

返回如下数据

0 <nil>
0 <nil>
0 <nil>
0 <nil>
0 <nil>
0 <nil>
0 <nil>
0 <nil>
VersionInfo: Age: 3, Version:7.47.0, Host:x86_64-pc-linux-gnu, Features:968605, SslVer: OpenSSL/1.0.2g, LibzV: 1.2.8, ssh:

问题已解决，代码中少了 easy.Perform().
