Question

我知道SO中有许多类似的问题，但是我在{中尝试了get，post，data，params等的每种组合{1}}包，但我无法提交表单。我要么返回一个空字符串，要么返回同一页面（即：不是按 Submit 之后我希望获得的页面）

requests

该站点最近发生了变化，我记得这些命令之一肯定可以正常工作。为什么现在都不工作？

Answer 1

您提到过，该网站最近已更改。看来它现在正在使用 form-data 来接收POST请求，并且还需要发送默认值。

总而言之，您的代码应如下所示：

import requests

webserver = 'http://stev.oapd.inaf.it/cgi-bin/cmd'

r = requests.post(webserver, headers=headers, files = files)

希望这会有所帮助！
