当我们执行 reflect.ValueOf(1) 时,虽然看起来是获取了基本类型 int 对应的反射类型,但是由于 reflect.TypeOf、reflect.ValueOf 两个方法的入参都是 interface{} 类型,所以在方法执行的过程中发生了类型转换。 Go 语言的函数调用都是值传递的,变量会在函数调用时进行类型转换。基本类型 int 会转换成 interface{}...

Reflection in computing is the ability of a program to examine its own structure, particularly through types; it’s a form of metaprogramming. It’s also a great source of confusion. (在计算机领域,反射是一种让程序——主要是通过类型——理解其自身结构的一种能力。它是元编程的组成之一,同时它也...
