go - 我如何在Go中过滤此输出

Question

我正在尝试过滤此的终端输出，但是我不确定如何执行此操作。我尝试将输出放入 slice 中，但是它们输出单独的 slice ，而且我不确定如何将这些 slice 连接在一起以构成一个 slice 。在搜索过滤输出时，我发现没有任何帮助，因此我希望有人可以给我解决方案。我想获取//abs.twimg.com

func main() {
    profileURL := "url"
    resp, err := soup.Get(profileURL)
    check("Couldn't send GET request:", err)

    parse := soup.HTMLParse(resp)

    find := parse.Find("head").FindAll("link")
    for _, i := range find {
        links := []string{i.Attrs()["href"]}
        log.Println(links)
    }
}

输出:

2020/06/09 08:54:55 [//abs.twimg.com  ]
2020/06/09 08:54:55 [//api.twitter.com  ]
2020/06/09 08:54:55 [//pbs.twimg.com  ]
2020/06/09 08:54:55 [//t.co  ]
2020/06/09 08:54:55 [//video.twimg.com  ]
2020/06/09 08:54:55 [//abs.twimg.com  ]

我希望这有帮助!

import (
        "log"
        "strings"
)

func main() {
    profileURL := "url"
    resp, err := soup.Get(profileURL)
    check("Couldn't send GET request:", err)

    parse := soup.HTMLParse(resp)

    find := parse.Find("head").FindAll("link")
    filter := make([]string, 0)
    for _, i := range find {
        // map[string]string
        if strings.Contains(i.Attrs()["href"], "//abs.twimg.com") {
                filter = append(filter, i.Attrs()["href"])
        }
    }
    log.Println(filter)
}
