curl http://127.0.0.1:7005/ping

2.2 计算token的md5值

请求示例:

curl http://127.0.0.1:7005/hex/123456

2.3 快速截图(GET)

请求示例:

curl http://127.0.0.1:7005/puppeteer?auth=123456&file=file:///root/1.png

  }
}

2.5 模板渲染(POST)

请求地址: http://127.0.0.1:7005/render

这里只是在2.4的基础上增加了模板渲染的功能，所有参数不变，新增了data参数，传递给art-template模板的数据

<style>
  .table {
    width: 100%;
    border-collapse: collapse;
  }

  .table th,
  .table td {
    border: 1px solid #ddd;
    padding: 8px;
    text-align: center;
  }

  .table th {
    background-color: #4CAF50;
    color: white;
  }

  .table .highlight {
    background-color: #f2f2f2;
  }
</style>

<table class="table">
  <thead>
    <tr>
      <th>#</th>
      <th>名称</th>
      <th>数量</th>
      <th>价格</th>
      <th>总计</th>
    </tr>
  </thead>
  <tbody>
    {{each items item index}}
    <tr class="{{index % 2 === 0 ? 'highlight' : ''}}">
      <td>{{index + 1}}</td>
      <td>{{item.name}}</td>
      <td>{{item.quantity}}</td>
      <td>{{item.price.toFixed(2)}}</td>
      <td>{{(item.quantity * item.price).toFixed(2)}}</td>
    </tr>
    {{/each}}
  </tbody>
  <tfoot>
    <tr>
      <td colspan="4" style="text-align: right;"><strong>总计</strong></td>
      <td>{{items.reduce((sum, item) => sum + item.quantity * item.price, 0).toFixed(2)}}</td>
    </tr>
  </tfoot>
</table>
