技术贴：抓取ERC20交易数据的docker容器开发

把ERC20上的交易数据抓取到docker容器中，今天试着用Golang写了一个代码，最终编译通过。

只是，过程中，docker及docker-compose的安装部署，实在令人生厌。

心得：容易部署方面，Linux比windows好用太多了。

package main

import (
"context"
"fmt"

"github.com/ethereum/go-ethereum/common"
"github.com/getamis/eth-indexer/model"
"github.com/getamis/eth-indexer/store/account"
"github.com/getamis/eth-indexer/store/sqldb"
"github.com/getamis/sirius/database"
"github.com/getamis/sirius/database/mysql"

)

func main() {
db, _ := sqldb.New("mysql",
database.DriverOption(
mysql.Database("ethdb"),
mysql.Connector(mysql.DefaultProtocol, "127.0.0.1", "3306"),
mysql.UserInfo("root", "my-secret-pw"),
),
)
addr := common.HexToAddress("0x756f45e3fa69347a9a973a725e3c98bc4db0b5a0")
store := account.NewWithDB(db)

account, err := store.FindAccount(context.Background(), model.ETHAddress, addr)
if err != nil {
    fmt.Printf("Failed to find account: %v\n", err)
} else {
    fmt.Printf("Find account, block_number: %v, balance: %v, \n", account.Balance, account.BlockNumber)
}

}
