Templates.ExecuteTemplate(w,"index.html",map[string]interface{}{"Games":games})}games是[]map[string]interface{}(sql查询的映射结果)在模板中:{{range$gval:=.Games}}{{howtomakesomethinglike:$gval.name.(string)}}{{end}}如何在模板中将map的interface{}值转换为字符串(或整数)？在'去'我可以做游戏[0]["name"].(string)当我执行$gval.name时，它会写入十六进制字符串
我有一个类似这个演示的数据结构。typeFamilystruct{firststringlaststring}typePersonstruct{namestringfamily*Family}funcmain(){per1:=Person{name:"niki",family:&Familys{first:"yam",last:"bari"}}Check(per1)}和代码:varvalidate*validator.ValidatefuncCheck(datainterface{}){varv=reflect.ValueOf(data)ifv.Kind()==reflect.Stru

我不确定为什么以下转换不起作用:import"fmt"funcmain(){v:=map[string]interface{}{"hello":"world"}checkCast(v)}funccheckCast(vinterface{}){_,isCorrectType:=v.(map[string]string)if!isCorrectType{fmt.Printf("incorrecttype") 最佳答案 map[string]interface{}与map[string]string不同。interface{}类型与str
