# 设置 - 截图

## 什么是截图？

当数据提取失败时，**会自动生成截图**以便您识别原因。失败时的页面状态和错误代码会一起提供，这对诊断问题有很大帮助。

## 截图页面布局

{% columns %}
{% column %}

<figure><img src="/files/8fce084622721a7dcce17b47aa10dad653f1be56" alt=""><figcaption></figcaption></figure>
{% endcolumn %}

{% column %} <mark style="color:red;">➊</mark> URL：尝试提取的网站地址。

<mark style="color:red;">➋</mark> Error details：显示发生的错误代码。

<mark style="color:red;">➌</mark> Date Time：指示错误发生的时间。

<mark style="color:red;">➍</mark> Screenshot：失败时的屏幕截图——这是识别原因的最重要线索。在上面的示例屏幕中，您可以看到提取失败是因为网站访问被阻止，没有连接到正常页面。
