请问这段代码运行结果是否应该返回error
因为实际他的值已经不是原来的值了
fmt.Println(cvt.IntE("12.1")) // 12 <nil>
fmt.Println(strconv.ParseInt("12.1", 10, 64)) // 0 strconv.ParseInt: parsing "12.1": invalid syntax
指万恶的protobuf，所有的接口都是指针，
这样类型转换就要套两层
proto.Uint32(cvt.Uint32(xxx))希望能有一套接口能直接完成这个转换
cvt.Uint32P(xxx)万谢
func StringMapE(val interface{}) (m map[string]interface{}, err error)// input
`{"name":"cvt","age":3.21}`
// expect
map[string]interface{}{"name": "cvt", "age": 3.21} map type// input
map[interface{}]interface{}{111: "cvt", "222": 3.21}
// expect
map[string]interface{}{"111": "cvt", "222": 3.21}struct type// input
struct {
Name string
Age int
}{"cvt", 3}
// expect
map[string]interface{}{"Name": "cvt", "Age": 3}妈呀，终于找到这种库了，有了这个库，岂不是可以像写Python一样随意转换了😃
package main
import (
"fmt"

func main() {
fmt.Print("7138826985640367621", "\n")
fmt.Print(cvt.Int64("7138826985640367621"), "\n")
}
输出
