I am trying to follow the tutorial here : https://goethereumbook.org/block-query/
In his code , he calls the header
and then hard codes it into blockNumber
.
header, err := client.HeaderByNumber(context.Background(), nil)
if err != nil {
log.Fatal(err)
}
fmt.Println(header.Number.String()) // 5671744
blockNumber := big.NewInt(5671744)
I have attempted to improve on this and converted the string to int64.
header, err := client.HeaderByNumber(context.Background(), nil)
if err != nil {
log.Fatal(err)
}
fmt.Println(header.Number.String())
var stringBlockNumber = header.Number.String()
int64BlockNumber, err := strconv.ParseInt(stringBlockNumber, 10, 64)
if err != nil {
log.Fatal(err)
}
blockNumber := big.NewInt(int64BlockNumber)
block, err := client.BlockByNumber(context.Background(), blockNumber)
if err != nil {
log.Fatal(err)
}
This works until in try to add the following line:
fmt.Println(block.Number.Uint64())
I get the following error in the terminal :
./queryBlock.go:41:26: block.Number.Uint64 undefined (type func() *big.Int has no field or method Uint64)
I would appreciate any pointers on this.
