使用 Python 绕过 Cloudflare ReCaptcha 挑战

Question

我想绕过网站开头的 Cloudflare ReCaptcha 挑战，用 Python 抓取它。

我有一个正在解决 ReCaptcha 问题的 API。如果我直接通过 Chrome 中的检查元素从 API 添加“g-recaptcha-response”并按下按钮提交，它将 100% 工作并绕过验证码。

截图来理解我的意思：

但是，我现在的问题是，如果我使用带有令牌和所有隐藏输入字段的 python 请求的所有参数向下面的请求 URL 发出 GET 请求，它将无法工作并且无法绕过它。它不会返回 cookie 名称“cf_clearance”。

以下是通过浏览器成功绕过 GET 请求的情况：

我是否遗漏了什么或者为什么 Cloudflare 不接受它？以及我如何让它通过 python 请求接受它。
