GetName()stringGetAge()int} AI代码助手复制代码 实现一个函数,将接口类型转换到结构体类型。例如: funcConvertInterfaceToStruct(p PersonInterface)(Person,error) {varperson Person value := reflect.ValueOf(p)ifvalue.Kind() == reflect.Ptr && !value.IsNil() { value = value.Elem()ifvalue.Kind()...

cannot convert a (type interface{}) to type string: need type assertion 此时,意味着整个转化的过程需要类型断言。类型断言有以下几种形式: 1)直接断言使用 var a interface{} fmt.Println("Where are you,Jonny?", a.(string)) 但是如果断言失败一般会导致panic的发生。所以为了防止panic的发生,我们需要在...
