Python Http发送请求浅析

# get 请求
requests.get(url, params)

# post 请求
requests.post(url, data)
# 文件上传
upload_files = {'file': open('report.xls', 'rb')}
requests.post(url, file=upload_files)  
# 设置header
headers = {'User-Agent': 'Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit'}
requests.post(url, headers=headers)
# 设置cookie
cookies = {'token': '12345', 'status': '摸鱼'}
requests.post(url, cookies=cookies)

# 先实例化一个对象
session = requests.session()
# 给 requests.session() 对象设置cookie信息，这个看情况使用，具体情况具体分析啊
cookies_dict = {}
session.cookies = requests.utils.cookiejar_from_dict(cookies_dict)
# 后面用法和直接使用requests一样了
# get请求
response = session.get(url)
# post请求
response = session.post(url, json=json_data)
result = response.json()
#获取登陆的所有cookies信息
print(result.cookies.values()) 

# post 请求
payload = {
        "data": "hello world"
    }
async with aiohttp.ClientSession() as session:
	async with session.post(url, json=payload) as resp:
		print(resp.status)
# get请求
# 创建使用session
async with aiohttp.ClientSession() as session:
	async with session.get(url) as resp:
		print(resp.status)
		res = await resp.text()
		return res

# 上传文件
files = {'file': open('report.xls', 'rb')}
async with aiohttp.ClientSession() as sess:
	async with sess.post(url, data=files) as resp:
		print(resp.status)
		print(await resp.text())

# 设置header, cookie
headers = {'User-Agent': 'your agent'}
cookies= {'cookies_are': '摸鱼'}
async with aiohttp.ClientSession(headers=headers, cookies=cookies) as session:
	async with session.get(url) as resp:
		print(resp.status)
		res = await resp.text()
		return res

data = {
    'name': 'autofelix',
    'age': 25
}

# get请求
httpx.get(url,params=data)
# post请求
httpx.post(url, data=data)

# 设置header,cookie,timeout
headers = {'User-Agent': 'your agent'}
cookies= {'cookies_are': '摸鱼'}
httpx.get(url, headers=headers, cookies=cookies, timeout=10.0)

# 使用client发送（同步）请求
with httpx.Client() as client:
   response = client.get(url)

import asyncio
import httpx

async def main():
    # 异步请求AsyncClient
    async with httpx.AsyncClient() as client:
        response = await client.get(url)
        print(response)

if __name__ == '__main__':
    # python3.7+ 支持写法
    # asyncio.run(main())
    # python3.6及以下版本写法
    loop = asyncio.get_event_loop()
    result = loop.run_until_complete(asyncio.gather(main()))
    loop.close()
