Let’s use Go for Infura.
package main
import (
"fmt"
"log"
"github.com/ethereum/go-ethereum/ethclient"
)
func main(){
_, err := ethclient.Dial("https://ropsten.infura.io/v3/44c8c501d2524f13a0312d42a0469990")
if err != nil {
log.Fatalf("Oops! There was a problem", err)
} else {
fmt.Println("Success! you are connected to Ropsten Network")
}
}I began to use the infura API for a startup project in 2017. At that time, the ethclient golang package had not been released by the go-ethereum team yet, so I looked around in github. In the end, I decided to develop my own package to interface the JSON RPC API and I released the “github.com/tarancss/ethcli” package.
One of the issues I encountered with other public clients, was that they would not support Basic Authentication in the RPC calls, so they would not be useful for Infura’s v3 API when you need a secret passphrase. I think this is the case for ethclient, unless I am missing something.
My ethcli package was tailored to my specific needs, however, it provides an easy to use functionality for most needs. Feel free to provide feedback and/or pull requests.
