grequest案例对比requests案例

grequets和requests案例各一个，使用上对比：

import grequests
import requests

headers = {
    "content-type": "application/json;charset=UTF-8",
    "authentication": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9"
                      ".eyJpc3MiOiJwYXNzcG9ydHRlc3Quc2VuZ3VvLm1lIiwiZXhwIjoxNjA5MjI4MzczLCJwYXNzcG9ydF9pZCI6MzI4OTg4MCwic3ViIjoiYXV0aF90b2tlbiIsImF1ZCI6ImxpbmdzaG91IiwiaWF0IjoxNjA4NjIzNTczfQ.UiKxI2gtDy9vl43F_i4305KaGeADAyuTpJxSwtXqAfY",
    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) "
                  "Chrome/72.0.3626.121 Safari/ "
}
url = 'https://cashiertest.sg.me/api/finance/getonedayshopprofit'
data = '{"date": "2020-12-22"}'

def g_request():
    res = [grequests.post(url=url, data=data, headers=headers)]
    rp = grequests.map(res)
    for i in rp:
        print(i.text)

def requests_():
    res = requests.post(url=url, data=data, headers=headers)
    print(res.text)

if __name__ == '__main__':
    g_request()
    requests_()

控制台输出都一样：
{"message":"请求成功","data":{"shop_profit":{"is_confirmed":false,"gross_profit":null,"gross_profit_rate":null},"shop_goods_profits":[]}}
{"message":"请求成功","data":{"shop_profit":{"is_confirmed":false,"gross_profit":null,"gross_profit_rate":null},"shop_goods_profits":[]}}

grequest标准使用：

import grequests  # gevent+request

request_list = [
    grequests.get('https://www.runoob.com/python3/python3-file-methods.html', timeout=0.1),
    grequests.get('https://www.zxgj.cn/g/tupiancaijian'),
    grequests.get('https://www.json.cn/')
]
# 响应列表
response_list = grequests.map(request_list)
# 取响应码(和request用于)
response_content = response_list[0].status_code
# 取json
# ips = [ret.json() for ret in response_list if ret and ret.status_code == 200]
print(response_content)
