Analyze block data

分析eth区块logs数据

根据区块高度扫描分析以太坊系（私有链、公链、测试链、侧链等）合约部署及交易信息 目前只实现了（ERC20，ERC721，ERC1155）三种协议的部署和交易信息。 主要使用eth_getLogs来获取log数据

测试案例

func TestCS_GetBlocks(t *testing.T) {
    c := client.C{
        Provider: "http://xxxxx", // 节点链接
    }
    cc, err := ethclient.Dial(c.Provider)
    if err != nil {
        t.Fatal(err)
    }
    cs := CS{
        Client:    cc,
        FromBlock: 1519251,
        ToBlock:   1519251,
        Ctx:       context.Background(),
    }
    blocks, err := cs.GetBlocks()
    if err != nil {
        t.Fatal(err)
    }
    jsonS, _ := json.Marshal(blocks)
    t.Log(string(jsonS))
}

返回数据

[
    {
        "contract_address": "0xEb433F1f5272bBaCCa3BF3f9d9527FbF5010aDe1",
        "from_address": "",

    }

分析eth区块交易数据（只针对ETH RECORD）

根据区块高度扫描分析以太坊系（私有链、公链、测试链、侧链等） 主要使用eth_getBlockByNumber来获取record数据，可在现有基础上进行自己的扩展

测试案例

func TestCS_GetETHLogsByNumber(t *testing.T) {
    c := client.C{
        Provider: "xxxx",
    }
    cc, err := ethclient.Dial(c.Provider)
    if err != nil {
            t.Fatal(err)
    }
    cs := CS{
        Client: cc,
        Ctx:    context.Background(),
    }
    blocks, err := cs.GetETHLogsByNumber(1655849)
    if err != nil {
        t.Fatal(err)
    }
    jsonS, _ := json.Marshal(blocks)
    t.Log(string(jsonS))
}

返回数据
