如何在python中模拟http请求？

import requests

# 发送GET请求
response = requests.get('http://example.com')
print(response.status_code)  # 打印响应状态码
print(response.text)  # 打印响应内容

# 发送POST请求
data = {'key1': 'value1', 'key2': 'value2'}
response = requests.post('http://example.com', data=data)
print(response.status_code)
print(response.text)

# 发送带有请求头的请求
headers = {'User-Agent': 'Mozilla/5.0'}
response = requests.get('http://example.com', headers=headers)
print(response.status_code)
print(response.text)

# 发送带有参数的请求
params = {'key1': 'value1', 'key2': 'value2'}
response = requests.get('http://example.com', params=params)
print(response.status_code)
print(response.text)
