now i have a signature in sig :3044022014d647cd08f1ea5b31d1e6539b6cbceb9182f6e7b2e29fb969354ef7e3434923022028b b4eda36af410149baa936322e7c0e46cc5540a3aa89c811bc3c360028bfd301

now i have a  hash :f27c6c3aa42563c958292922be1e53fe107f4db0dfadba11122f0b12bf77f3ab

now i have a  pubkey  :04b0bd634234abbb1ba1e986e884185c61cf43e001f9137f23c2c409273eb16e6537a576782eba6 68a7ef8bd3b3cfb1edb7117ab65129b8a2e681f3c1e0908ef7b


this is my go code to verify it but i false，it is problem me !   so why it is fault???：

package main

import (
   "crypto/ecdsa"
   "crypto/elliptic"
   "fmt"
   "math/big"
   "encoding/hex"
)


func main(){


   pubkey,_:=hex.DecodeString("b0bd634234abbb1ba1e986e884185c61cf43e001f9137f23c2c409273eb16e6537a576782eba668 a7ef8bd3b3cfb1edb7117ab65129b8a2e681f3c1e0908ef7b");



   curve := elliptic.P256()
   //length
   keyLen := len(pubkey)

   x := big.Int{}
   y := big.Int{}
   x.SetBytes(pubkey[:(keyLen / 2)])
   y.SetBytes(pubkey[(keyLen / 2):])

   rawPubKey := ecdsa.PublicKey{curve, &x, &y}


   //hash
   hash,_:=hex.DecodeString("f27c6c3aa42563c958292922be1e53fe107f4db0dfadba11122f0b12bf77f3ab")


  
   r := big.Int{}
   s := big.Int{}
   rr,_:=hex.DecodeString("14d647cd08f1ea5b31d1e6539b6cbceb9182f6e7b2e29fb969354ef7e3434923")
   ss,_:=hex.DecodeString("28bb4eda36af410149baa936322e7c0e46cc5540a3aa89c811bc3c360028bfd3")

   r.SetBytes(rr)
   s.SetBytes(ss)

  

   if ecdsa.Verify(&rawPubKey, hash[:], &r, &s) == false {
      fmt.Printf("%s\n", "false")
   }else{
      fmt.Printf("%s\n", "true")
   }

}
