在python中使用单独的主机名和url发出post请求

import urllib.request
import urllib.parse

url = "https://example.com/post"
data = {"key1": "value1", "key2": "value2"}  # POST请求的参数

# 将参数转换为bytes类型
data = urllib.parse.urlencode(data).encode("utf-8")

# 创建请求对象
req = urllib.request.Request(url, data=data)

# 设置请求头中的Host字段
req.add_header("Host", "example.com")

# 发出POST请求
response = urllib.request.urlopen(req)
result = response.read().decode("utf-8")
print(result)

import requests

url = "https://example.com/post"
data = {"key1": "value1", "key2": "value2"}  # POST请求的参数

# 设置请求头中的Host字段
headers = {"Host": "example.com"}

# 发出POST请求
response = requests.post(url, data=data, headers=headers)
result = response.text
print(result)
