strings.Trim被去掉字母 「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 

繼承人我的代碼：

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/")) 
     } 
    } 

難道我失去了我的心？正斜槓與此有關嗎？如果你知道，請解釋發生了什麼事。

Answer 1

strings.Trim()的第二個參數是'cutset'，也就是從字符串中移除的一組符，'i'就是其中之一。

要返回路徑的最後一個元素，請使用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)) 

結果：

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