Question

很久以来，我尝试了其他方法来使用python请求向表单提交POST请求，但是没有运气。我正在尝试将'3513'发送到表单的文本字段，其名称为TextTrnNo，然后从网站获取信息。

我失败的一种方法：

import requests

payload = {'TextTrnNo': '3513'}


r = requests.post('https://appiris.infofer.ro/mytrainro.aspx', data=payload)

print(r.text)

我得到的输出：

Answer 1

您的代码正确无误，就像它发送带有所需数据的发件请求一样。但是，在查看发送到站点的网络请求时，我注意到您缺少几个字段，这些字段阻止站点解析发布请求。这些字段是：

Button1
__VIEWSTATE

它们可以完全为空，它们只需要作为发布请求的一部分，从而使您的完整有效负载变量：

payload = {'TextTrnNo': '3513', 'Button1': '', '__VIEWSTATE': ''}

这将返回不同的输出，其中包括某种表。

无法将POST请求发送到旧网站
