Refer to the following code:

package main

import (
	"context"
	"fmt"
	"strings"

)

// Substrate well-known mnemonic:

var MY_MNEMONIC = "bottom drive obey lake curtain smoke basket hold race lonely fit walk"

var RPC_ADDRS = []string{
	"wss://testnet-rpc0.cess.cloud/ws/",
	"wss://testnet-rpc1.cess.cloud/ws/",
	"wss://testnet-rpc2.cess.cloud/ws/",
}

var oss_url = "http://deoss-pub-gateway.cess.cloud/"
var bucket_name = "my-bucket"

func main() {
	sdk, err := cess.New(
		context.Background(),
		cess.ConnectRpcAddrs(RPC_ADDRS),
		cess.Mnemonic(MY_MNEMONIC),
	)
	if err != nil {
		panic(err)
	}
	// upload object
	fmt.Println(sdk.StoreObject(oss_url, strings.NewReader("test data"), bucket_name))
}
