    BlockDog 方块狗是公鹿钱包团队推出的网站。他们借用这个网站提供公共 API 服务以方便 EOS 开发者进行 EOS 相关开发。

    本文整理使用 BlockDog API 查询 EOS actions。

    BlockDog API 官方文档:https://open-api.eos.blockdog.com/

    使用 BlockDog API 需要申请 apikey//www.blockdog.com/openApi

    免费版 apikey 支持 HTTPS API 调用频次≤3次/秒,WebSocket API 订阅合约/账户调用峰值≤3次。

    BlockDog API 查询 EOS actions:

    请求参数:

    code: 动作执行的合约名, 如果related=true, 查询结果则包含执行的合约名为code或者转账转入/转出为code

    related: 是否为相关查询, 默认为 false, 如果为 true 查询结果包含执行的合约名为code或者转账转入/转出为code

    name: 合约动作名;

    account_name: 发起者 EOS 账号;

    status: 交易状态;

    start_block_num: 开始区块高度(包括);

    end_block_num: 结束区块高度(不包括);

    start_block_time: 开始区块时间(包括), 格式为2018-01-01T00:00:00;

    end_block_time: 结束区块时间(不包括), 格式为2018-01-01T00:00:00;

    sort: 按时间排序(1, DESC 2, ASC) 默认1;

    size: 返回记录数, 默认20, 最大100;

    page: 页码,默认1, (page-1) * size + size 必须小于 10000.

    示例:

    直接查询指定合约账户 actions 并设置返回 size 为2:

    Node.js 示例:

    let request = require("request");
    
    let options = { method: 'POST',
        url: 'https://open-api.eos.blockdog.com/v1/third/get_actions',
        headers:
            { 'content-type': 'application/json',
                apikey: '5b4added-e80c-41fb-b5a9-16269d2de79b',
                accept: 'application/json;charset=UTF-8' },
        body: '{"code":"eosio.token","size":2}' };
    
    request(options, function (error, response, body) {
        if (error) throw new Error(error);
    
        console.log(body);
    });
    

    返回的 JSON 示例:
