我正在编写一个python程序，该程序需要能够在网站上解决验证码。 我想使用 2 验证码。 我使用硒编写了一个 python 脚本，它将完成除解决验证码之外我需要做的所有事情。 当我单击 2captcha.com"API"选项卡时，将显示以下内容（以及其他参数）：
您可以使用两种可用格式上传验证码：
多部分和基数64。
多键示例：
<form method="post" action="http://2captcha.com/in.php" enctype="multipart/form-data">
<input type="hidden" name="method" value="post">
Your key:
<input type="text" name="key" value="YOUR_APIKEY">
The CAPTCHA file:
<input type="file" name="file">
<input type="submit" value="download and get the ID">
</form>
YOUR_APIKEY - 是 32 个符号长度的密钥。
Base64 示例：
<form method="post" action="http://2captcha.com/in.php">
<input type="hidden" name="method" value="base64">
Your key:
<input type="text" name="key" value="YOUR_APIKEY">
The CAPTCHA file body in base64 format:
<textarea name="body">BASE64_FILE</textarea>
<input type="submit" value="download and get the ID">
</form>
YOUR_APIKEY - 是 32 个符号长度的密钥。
BASE64_FILE - 是 base 64 编码的图像正文。
我非常了解python，以及它的大部分科学和数学模块，但我对与Web相关的编程有点陌生。 上面的代码看起来像 html。 我将如何使python程序执行上述html指令？
我来自2CAPTCHA团队，我们有示例python。您可以使用以下代码：
"""
这是如何通过谷歌验证码v2的示例。我使用python + selenium + phantomJS来做到这一点。Phantom JS是用于自动化Web测试的无头浏览器。我用它来报废页面并绕过谷歌验证码。要使用它，您应该安装phantomJS（并从linux系统案例中的源代码构建）并安装Selenium python模块
谷歌验证码出现在iframe的页面上。您应该废弃其元素，单击图像并在单击"确定"后检查错误消息。
