配置

如何配置Thordata 的抓取浏览器

本文将引导您完成 Thordata 抓取浏览器的整个配置与使用流程，包括凭证获取、基础配置、示例脚本运行及实时会话管理。遵循本指南，您将能够快速上手并高效地进行网页数据抓取。

在开始之前，请先准备好您的账户凭证，即用于网络自动化工具的用户名和密码。您可以在 Thordata 抓取浏览器区域的 “演示场”标签页中直接查看这些凭证信息。我们假设您已获得有效凭证，若尚未获取，请从 Thordata 处申请。

在使用抓取浏览器之前，需完成基础环境配置。我们将逐步指导您完成身份凭证的配置、API 基本参数设置，以及如何在操作控制台中管理实时浏览器会话，助您更顺畅地启用浏览器功能。

抓取浏览器快速入门示例

我们为您准备了一系列抓取示例，帮助快速入门。您只需替换脚本中的个人凭证和目标网址，即可根据实际业务需求进行调整和扩展。如需编写更复杂的抓取逻辑，可参考 Thordata 官方文档中支持的框架协议说明。

您可以在仪表板中的“演示场”中在线调试脚本，也支持在本地环境中执行实际抓取任务。若选择本地运行，请确保已安装相应依赖（参考 Thordata 支持的框架协议），正确配置身份凭证后，执行示例脚本即可获取目标数据。

浏览器API初始导航

根据抓取浏览器的会话管理机制，每个会话仅允许执行一次初始导航，即首次加载目标网站以进行数据提取的操作。在此会话起点确立后，用户便可在该网站内部通过点击、滚动等交互动作自由跳转。然而，任何需要从初始导航阶段重新开始的抓取任务——无论目标是同一网站还是不同网站——都必须通过创建新会话来完成。

会话时间限制

自动超时机制：所有浏览器会话均受限于30分钟的最大存活时间。若会话未通过脚本指令主动终止，系统将在此时间后自动将其结束。
Web控制台特殊限制：在Web控制台环境中，系统强制实行单账户单一活动会话的策略。为避免资源冲突与潜在错误，请在您的自动化脚本中务必加入显式关闭会话的逻辑。
