strings.Trim正在删除字母＆＃34; i＆＃34; （golang）

Question

full path: views/admin/users.html
trim set (views): /admin/users.html
trim set (views/): admin/users.html

full path: views/index.html
trim set (views): /index.html
trim set (views/): ndex.html

继承我的代码：

    err := filepath.Walk("./views", func(path string, info os.FileInfo, err error) error {
        if strings.Contains(path, ".html") {
            bytes, err := ioutil.ReadFile(path)
            if err != nil {
                panic(err)
            }
            fmt.Println("full path:", path)
            fmt.Println("trim set (views):", strings.Trim(path, "views"))
            fmt.Println("trim set (views/):", strings.Trim(path, "views/"))
        }
    }

我是否忘记了？正斜杠与此有关吗？如果你知道的话，请解释一下。

Answer 1

strings.Trim()的第二个参数是＆＃39; cutset＆＃39;，即从字符串中删除的一组符文，以及＆＃39; i＆＃39;是其中之一。

要返回路径的最后一个元素，请使用path.Dir()。

Answer 2

您也可以使用strings.Replace：

fmt.Println("full path:", path)
fmt.Println("trim set (views):", strings.Replace(path, "views", "", -1))
fmt.Println("trim set (views/):", strings.Replace(path, "views/", "", -1))

结果：

full path: views/index.html
trim set (views): /index.html
trim set (views/): index.html
