Python基础-网络编程request使用

import requests
#get请求

url = "http://127.0.0.1:8000/login"
data={"username":"jmy1235","pwd":123456}
req = requests.get(url+"?"+"username=jmy1235&pwd=123456")
req = requests.get(url,data)
print(req.text)  #字符串

##post请求
url = "http://127.0.0.1:8000/login"
data={"username":"jmy1235","pwd":123456}
req = requests.post(url+"?"+"username=jmy1235&pwd=123456")
req = requests.post(url,data)
print(req.text)  #字符串
print(req.json())  #返回的是字典，如果接口返回的是json的话，那么才能用.json

#请求报文为json类型
def get_sign(url,data):
    res = requests.post(url,data).json()
    print(res)
    return res['sign']
print(get_sign(url,data))
sign = get_sign(url,data)
data2 = {
    "username":'jmy1235',
    "real_name":"处长",
    "class":"巨蟹座",
    "phone":"19312345673",
}

r = requests.post('http://127.0.0.1:8000/add_stu',json=data2)  #请求报文为json类型的
print(r.text)

##发带cookie和header
sign = get_sign(url,data)
cookie  = {'sign':sign}
header = {'tangxiaofeng':'sevenqq'}
data2 = {
    "username":'jmy1235',
    "real_name":"孙树江",
    "class":"巨蟹座",
    "phone":"19312345674"
}
url = "http://127.0.0.1:8000/add_stu2"
r = requests.post(url,json=data2,cookies=cookie,headers=header)  #header里面传的时候不能有中文
print(r.text)

#下面是上传文件的
file ={
    'file_name':open('hahah.py',encoding='utf-8')
}
data = {"username":"jmy",'pwd':123456}
url="http://127.0.0.1:8000/upload"
r = requests.post(url,data,files=file)
print(r.text)
