弹出模式中的验证码：检测和token 提交

用户单击“提交”，然后会弹出一个带有验证码挑战的模式。 sitekey 不在初始页面源中 - 它会在模式打开时动态加载。您的自动化脚本需要触发模式，等待验证码呈现，提取参数，解决并在模式超时或用户会话过期之前注入令牌。

模态时序注意事项

故障排除

常问问题

如何检测无需点击触发器即可自动打开的模式？

使用 MutationObserver 来监视 DOM 中出现的新元素。在导航到该页面之前进行设置。当模态元素被添加并变得可见时，您的观察者会触发，您可以启动验证码检测流程。

如果验证码位于模态 iframe 内怎么办？

如果模式包含带有验证码的 iframe，请将此方法与 iframe 处理结合起来。检测到模态后，切换到模态内的 iframe 上下文以提取 sitekey。

我应该在解决验证码之前还是之后填写表单字段？

前。首先填写所有其他表单字段，然后最后解决验证码。这可以最大限度地缩短获取令牌和提交表单之间的时间，从而降低过期风险。
