项目启动与重启

执行 docker-compose up 启动文件

如果想要修改配置文件, 直接编辑当前目录下的 config.ini, 修改完成后, 执行 docker-compose down -v, docker-compose up 即可.

命令行执行体验

可以在 ~/.bashrc 中添加如下命令

alias eosioc='docker-compose exec walletd /opt/eosio/bin/eosioc -H eosiod'

添加完记得 soucre ~/.bashrc 促使生效

这样子可以直接通过终端执行 eosioc, 其实实际上已经访问到 docker 内部,非常方便

执行 eosioc get info
可以看到返回结果类似:

EOS 智能合约体验

接上文: #4

官方文档地址: https://github.com/EOSIO/eos#example-currency-contract-walkthrough

智能合约示例

首先启动节点

docker-compose up

导入帐号

在创世区块的配置中已经存在一个 eosio 的账户, 把私钥导入.

eosioc wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

为 "currency" 合约创建帐号

先生成2个密钥对:

rkd@mac:~/blockchain/eos/Docker$ eosioc create key
Private key: 5KMohsQ5cqXGgMRPH5qXqaTpRhrThwtGT7e8sqS7KuxXRxGLFfW
Public key: EOS55iuKLbH2XhNv4pJXjNtxTJYoD5Xes2PuB4N7LYfgdeEjFPWat   // owner_key
rkd@mac:~/blockchain/eos/Docker$ eosioc create key
Private key: 5K8T42F56S6VX3bFh3sC6UcNjC1aQEY37AmK2rdnXVzsSX3YeCT
Public key: EOS6RPNryk7rxkrcxKEigmrNBS4dzGcUqdoWT4HupbrbYnVro5npM  // active_key

通过 eosio 这个帐号, 创建 currency 帐号

eosioc create account eosio currency EOS55iuKLbH2XhNv4pJXjNtxTJYoD5Xes2PuB4N7LYfgdeEjFPWat EOS55iuKLbH2XhNv4pJXjNtxTJYoD5Xes2PuB4N7LYfgdeEjFPWat

会返回一大段 json 串就说明成功了

查询一下:
eosioc get account currency

返回结果:

{
  "account_name": "currency",
  "permissions": []
}

导入钱包私钥:

eosioc wallet import 5KMohsQ5cqXGgMRPH5qXqaTpRhrThwtGT7e8sqS7KuxXRxGLFfW
eosioc wallet import 5K8T42F56S6VX3bFh3sC6UcNjC1aQEY37AmK2rdnXVzsSX3YeCT

上传 "currency" 合约

上传前可以查看下:

eosioc get code currency
code hash: 0000000000000000000000000000000000000000000000000000000000000000

上传:

eosioc set contract currency ../../contracts/currency/currency.wast ../../contracts/currency/currency.abi

返回的结果中带有 transaction_id 字段那就说明成功了

你可以再查询验证下:

eosioc get code currency

返回结果看起来像这样子:

code hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975

使用这个合约前,要现先生成代币.

eosioc push action currency issue '{"to":"currency","quantity":"1000.0000 CUR"}' --permission currency@active

验证下看看余额对不对:

eosioc get table currency currency account
{
  "rows": [{
     "currency": 1381319428,
     "balance": 10000000
     }
  ],
  "more": false
}

通过合约交易

eosioc push action currency transfer '{"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}' --permission currency@active

返回的结果中带有 transaction_id 字段那就说明成功了

通过合约查询余额

eosioc get table eosio currency account
{
  "rows": [{
      "currency": 1381319428,
      "balance": 200000
       }
    ],
  "more": false
}
eosioc get table currency currency account
{
  "rows": [{
      "currency": 1381319428,
      "balance": 9800000
    }
  ],
  "more": false
}

显然余额已经发生变化了.

偶尔写写东西感觉也不错~

让终端 sudo 时用上 Touch ID

用了一段时间 MacBook Pro with TouchBar 感觉开机或唤醒时读指纹还是很方便的，但安装一些软件或执行命令操作时还是需要输入密码，似乎不那么省事，对设置复杂密码也不够友好。今天学到了一个新技巧，让我们在终端里sudo执行命令时不再需要手输密码，而是Touch ID验证。

修改/etc/pam.d/sudo这个文件，建议用
sudo vim /etc/pam.d/sudo

在第一行增加
auth sufficient pam_tid.so

现在尝试下 sudo 操作吧，应该会看到提示识别指纹而不是输入密码了。

如果你使用了 tmux 需要添加额外的配置

https://github.com/fabianishere/pam_reattach

git clone https://github.com/fabianishere/pam_reattach
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr/local <PATH-TO-SOURCE>
make
sudo make install

修改/etc/pam.d/sudo这个文件，建议用
sudo vim /etc/pam.d/sudo

在第一行增加
auth optional pam_reattach.so

然后就可以顺利使用了

从 etherscan 获取可用的 peer

https://etherscan.io/nodetracker/nodes

var enodeTable = document.getElementsByClassName("table")[0]
var enodeList = []
var info = []
var commandList = []


for (i = 1; i < enodeTable.rows.length; i++) {
    var enodeUrl = "";
    var command= "";
    // GET THE CELLS COLLECTION OF THE CURRENT ROW.
    var objCells = enodeTable.rows.item(i).cells;
    var btn = objCells[8]
    copySpan = btn.getElementsByClassName("d-none")
    enodeUrl = copySpan[0].innerText
    enodeList.push(enodeUrl);
    command = 'admin.addPeer("' + enodeUrl + '");';
    commandList.push(command);
}
var arrLength = commandList.length
for(i=0; i< arrLength; i++)
{
    console.log(commandList[i]);
}
