python爬虫,requests,html,javascript

在用python的requests获取学校的教室信息时，在浏览器抓包时只有一条，URL后半部分是这样的/Room/GetUsingRoomList?vpn-12-o1-...:8080，（”“省略了ip地址），这个url后面也没跟什么信息啊，为什么可以返回相应的教室信息
而我用requests请求时会报错
代码：
import requests
url =/Room/GetUsingRoomList?vpn-12-o1-...*:8080
h={
"Accept":
,"Accept-Encoding":
"Accept-Language": "zh-CN,zh;q=0.9",
"Connection": "keep-alive",
"Cookie":
"Host":
"Referer":
"Sec-Fetch-Dest": "document",
"Sec-Fetch-Mode": "navigate",
"Sec-Fetch-Site": "same-origin",
"Sec-Fetch-User":
"Upgrade-Insecure-Requests":
"User-Agent":
"sec-ch-ua":
"sec-ch-ua-mobile":
"sec-ch-ua-platform": '"Windows"'
}
response = requests.post(url,headers=h) 在这就报错了
responses = response.text
print(responses)

连接出错了
