如何以编程方式将验证码图像上传到 python（给定 html）中的此求解服务？
How can I programatically upload captcha images to this solving service in python (html given)?
我正在编写一个 python 程序，需要能够解决网站上的验证码问题。我想使用 2captcha。我已经使用 selenium 编写了一个 python 脚本，除了解决验证码之外，它可以完成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）：
您可以上传两种格式的验证码：
多部分和 Base64。:
Multipad 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 - 是您的 32 个符号长度的密钥。
Base64 样本：
<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 - 是您的 32 个符号长度的密钥。
BASE64_FILE - 是 base 64 编码的图像主体。
我知道 python，它的大部分科学和数学模块都很好，但我对网络相关编程有点陌生。上面的代码看起来像 html。我如何让 python 程序执行上面的 html 指令？
查看requests模块
url = 'http://2captcha.com/in.php'
files = {'file': open('image.png', 'rb')}

# do something with the response data
我来自 2captcha 团队，我们有样本 python。
您可以使用代码：
"""
这是如何通过 google recaptcha v2 的示例。
我已经使用 python + selenium + phantomJS 来做到这一点。
Phantom JS 是一种用于自动化 Web 测试的无头浏览器。我用它来废弃页面并绕过 google 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）和安装 selenium python 模块
Google 验证码出现在 iframe 的页面上。你应该废弃它的元素，单击图像并在单击确定后检查错误消息。
