如果不在范围[0,NumMethod())内,会导致panic.// 对于非接口类型T或*T,返回的方法的type和Func字段描述其第一个参数为接收器的函数,并且只有导出的方法才可访问// 对于接口类型,返回方法的类型字段给出了方法签名,没有接收器,而Func字段为零// 方法按字典顺序排序Method(int) Method// MethodByName返回在类型的...
另外,显式初始化一个大数只能到上限math.MaxInt64,如果想设置比这还大的数,则只能使用如下方法,即从byte到big int: Convert byte array to big.Int import"math/big"z :=new(big.Int) z.SetBytes(byteSliceHere) or: func Base64ToInt(sstring) (*big.Int, error) { data, err :=base64.StdEncoding...
