我想使用Python发送匿名电子邮件。我使用一个名为emkei.cz的在线匿名电子邮件发送工具。我想以编程方式使用这个工具。
如何在网站(emkei.cz(上填写该表格并提交以使用python-requests发送匿名电子邮件？
我不想使用像selenium或mechanize这样的东西，因为它们很慢(即使我无头地运行selenium(，并且对于我可以通过请求模拟的基本HTML表单来说是不需要的。
我尝试过的
我填写了表格，并在Microsoft Edge开发工具的网络选项卡中检查了提交表格时提出的请求。我尝试使用Python中的requests库来模拟这些请求。
邮件已成功发送。我记下了标题和有效负载(数据(。我用相同的表单值编写了一个简单的Python脚本，试图发送邮件。然而，它没有起作用。
为了调试，我检查了r.text。它返回的是我刚刚填写的相同输入表，而不是成功消息"电子邮件发送成功"。
这是我正在使用的代码：

我的猜测是，这与captcha和g-recaptcha-response有效载荷有关。不过，在填写表格时，我没有被要求提供任何captcha。
请尝试访问网站(Emkei的匿名邮件，也链接到上面(，并告诉我如何通过它以编程方式发送电子邮件。
存在不可见的reCAPTCHA，因此需要渲染页面以获得g-recaptcha-response
https://developers.google.com/recaptcha/docs/versions#recaptcha_v2_invisible_recaptcha_badge
您可以使用requests-html，它将在第一次渲染时自动下载Chromium
https://pypi.org/project/requests-html/
-
在POST请求之前，在
send_email函数中渲染页面并设置captcha：from requests_html import HTMLSession session = HTMLSession() response = session.get("https://emkei.cz/") # response.html.render() for _ in range(10): if response.html.search('name="g-recaptcha-response" value="{}"') is None: response.html.render() payload['g-recaptcha-response'] = response.html.search('name="g-recaptcha-response" value="{}"')[0] -
注释
"Content-Type": "multipart/form-data; boundary=...标题：# "Content-Type": "multipart/form-data; boundary=...您不应该指定自己的边界，因为多部分数据是由
requests构建的。https://github.com/psf/requests/issues/1997 -
在
request.status_code != 200旁边添加以下故障检查：# if "The invisible reCAPTCHA test wasn't successful. Please, try again." in request.text: # return -1 if "E-mail sent successfully" not in request.text: return -1
在Windows上，您可能会遇到requests-html试图下载Chromium的问题
https://github.com/psf/requests-html/issues/325
不可见的reCAPTCHA仍可能阻止请求
最初，单个response.html.render()运行良好。
在1小时内运行xx次后，我需要for _ in range(10)，在render():期间偶尔会得到TimeoutError
pyppeteer.errors.TimeoutError:超过导航超时：超过8000毫秒。
在1小时内运行xxx次后，https://emkei.cz/大多返回CCD_ 19。
