    'passwd':'aA123456'
} #請求數據
req = requests.post(url,data)#發送post請求
print(req.json())

3.入參是json類型
import random
phone = random.randint(10000000000,99999999999)
url = 'http:///api/user/add_stu'

    "name":"yyy",
    "grade":"天蠍座",
    "phone":phone,
    "sex":"男",
    "age":28,

cookie = {'niuhanyang':'337ca4cc825302b3a8791ac7f9dc4bc6'}
req = requests.post(url,data,cookies=cookie)
print(req.json())


5.添加header
url = 'http:///api/user/all_stu'
