//能量值费用：「创建NFT/MT类别」、「发行NFT/MT」为 40 万能量值（等值人民币：0.1元），其他交易类型为 20 万能量值（等值人民币：0.05元）

// 初始化 OPB 网关账号（测试网环境设置为 nil 即可）
// 开启 TLS 连接
// 若服务器要求使用安全链接，此处应设为true,后面需要填写tlsServiceName
//若此处设为false可能导致请求出现长时间不响应的情况
// 若开启 TLS 连接，则必须设置验证证书的主机名

创建离线链账户：
address,mnemonic,err:=client.key.add(name,password)

查询交易结果(根据交易哈希查询)：
result,err:=client.BaseClient.QueryTx(tx_hash)

代付授权(用于离线链账户上链)：
basic := &feegrant.BasicAllowance{
        SpendLimit: atom,        //授权额度
        Expiration: &threeHours, //过期时间
}
//链账户地址在这里需要转换一下
granter, _ = types.AccAddressFromBech32(address)
grantee, _ = types.AccAddressFromBech32(address)
// 授权
result, err := client.Feegrant.GrantAllowance(granter, grantee, basic, baseTx)
