字符串。Trim正在删除字母“ i”（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

Heres my code:

    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/"))
        }
    }

Have I lost my mind? Does the forward slash have something to do with this? Please explain what's going on if you know.

The second parameter to strings.Trim() is a 'cutset', ie, a set of runes to remove from the strings, and 'i' is one of them.

To return all but the last element of path, use path.Dir().
