使用Python请求发布到asp.net表单失败

我试图使用Python请求将值发布到

这是我迄今为止在Python中尝试的：

import requests
url = "http://www.myvisajobs.com/Search_Visa_Sponsor.aspx?N="
data = {"ctl00$ctl00$ContentPlaceHolder1$ContentPlaceHolder1$txtCompany":"Microsoft"}
r = requests.post(url,data)
print(r.text)

---

它只返回原始HTML。我正在尝试返回生成的HTML。我的直觉是我在做一些根本错误的事情，但我不确定是什么

在搜索帖子请求中发送的参数比引用公司名称的

ctl00$ctl00$contentplaceholder 1$contentplaceholder 1$txtCompany

多得多

相反，为了使事情变得透明和简单，我将使用“自动填充”所需的其他表单POST参数。示例工作代码：

from robobrowser import RoboBrowser


url = "http://www.myvisajobs.com/Search_Visa_Sponsor.aspx?N="

browser = RoboBrowser(history=True)
browser.open(url)

form = browser.get_form(id='aspnetForm')
form['ctl00$ctl00$ContentPlaceHolder1$ContentPlaceHolder1$txtCompany'].value = 'Microsoft'
browser.submit_form(form)

results = browser.select('div#ctl00_ctl00_ContentPlaceHolder1_ContentPlaceHolder1_divContent table tr')[1:]
for result in results:
    cells = result.find_all("td")

    print(cells[2].get_text(strip=True))

它打印搜索结果中的公司名称：

Microsoft Corporation

我编辑了标签以反映这一点。谢谢。如果你不介意的话。。。发送的其他参数是什么？@user32882只需打开浏览器开发人员工具的“网络”选项卡，提交表单并检查将出现在网络网格中的POST请求。希望有帮助。
