为什么 Puppeteer-Extra 的 solveRecaptchas() "not a function"？

Question

我正在尝试使用 Puppeteer 和 puppeteer-extra-plugin-recaptcha through Apify 来解决登录页面上的 Recaptcha。

我会及时进行完全登录。现在，我正在尝试使用 Google 的演示来做 Recaptcha 解决方案。 puppeteer-extra-plugin-recaptcha 通过 API 键点击 2captcha 服务来解决问题。

不幸的是，在我的代码中，重要的 solveRecaptchas() 抛出错误：

TypeError: page.solveRecaptchas is not a function

完整错误：

            // additional code

        },
    });

    await crawler.run();

    }
);

我了解到的可能原因包括：

• Not defining details for the solving plugin - notably, the API key - 但我好像已经这样做了
• Something about different methods for solving in pre-existing browser pages（似乎不相关？）。
• iFrame 的可能影响。但是，当我 loop to get any child frames 时，我仍然得到错误。

这可能是您提供的示例中的一个遗漏，但您似乎没有在任何地方调用 addPlugins() 函数，因此根本没有使用该插件。
