老许的bug ?

你确定没抄错？ imgid := fileInfo.Name 这里应该是：fileInfo.Name() os.FileInfo 接口的Name()方法

给个上下文啊。imgid 是啥类型？

连个图片也不支持啊，http://www.freeimagehosting.net/9ygno.png package main func listHandler(w http.ResponseWriter, r *http.Request) { fileInfoArr, err := ioutil.ReadDir("./uploads") if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } var listHtml string for _, fileInfo := range fileInfoArr { imgid := fileInfo.Name listHtml += "<li><a href=\"/view?id=" + imgid + "\">imgid</a></li>" } io.WriteString(w, "<ol>"+listHtml+"</ol>") }
