向 Discord 提交 hcaptcha 驗證碼令牌以使用 selenium 創建帳戶

Question

我正在使用 python selenium 創建一個 Discord 帳戶 ( https://discord.com/register )，但它受 hcaptcha 保護。 我有一個驗證碼 API (2captcha/capmonster) 來返回驗證碼令牌並將其放入 g-captcha-response 文本區域。 通常有一個提交按鈕，之后您可以單擊該按鈕，然后您可以訪問該站點（如果驗證碼標記正確），但是一旦您手動完成驗證碼，Discord 會自動重定向您。 我假設 Discord 正在使用 hcaptcha 回調函數。 但是我沒有找到回調函數，所以我可以在輸入驗證碼令牌后調用它。

這是我到目前為止的代碼：

# code to submit captcha token

您應該嘗試手動解決驗證碼，看看有什么區別，注意元素的任何變化？

將驗證碼標記注入 h-captcha-response 和 g-recaptcha-response 元素總是會引發錯誤。

我給你舉個例子，有時在解決 hCaptcha 后會生成一個新的隱藏元素，所以你可以做的是創建完全相同的元素

js_script = f"""
          let captchaElement = document.getElementById('captcha')
          let inputElement = document.createElement('input');
          inputElement.setAttribute('type', 'hidden');
          inputElement.setAttribute('name', 'response_token');
          inputElement.setAttribute('value', "{captcha_token}");
          captchaElement.appendChild(inputElement)
"""
self.driver.execute_script(js_script)
