Requests请求格式

GET

get: params
没有请求体，params就是追加在urL后面的查询参数
接口地址?key=value&key=value&…

payload = {'key1': 'value1', 'key2': 'value2'}
headers = {'user-agent': 'my-app/0.0.1'}
url = "https://httpbin.org/get"

r = requests.get(url, params=payload, headers=headers)

查看请求地址print(r.url)

https://httpbin.org/get?key2=value2&key1=value1

查看请求头print(r.request.headers)

{'user-agent': 'my-app/0.0.1', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive'}

查看响应头print(r.headers)

url = "https://httpbin.org/post"

方式一：参数类型为字典、元组列表、字节或类似文件

url = "https://httpbin.org/put"

方式一：参数类型为字典、元组列表、字节或类似文件

r.json()	返回请求体为json串
r.status_code	响应码

获取cookie

方式一

import requests
# 第一步 实例化Session对象
s = requests.Session()

print("登陆之前的cookies:",s.cookies)

# 第二步：登陆，得到cookies鉴权。
login_url = "https://www.ketangpai.com/UserApi/login"
login_datas = {"email":"2501768591@qq.com",
             "password":"nmb_python",
             "remember":0}
response = s.post(login_url,data=login_datas)
print("登陆响应的cookies: ",response.cookies)

print("登陆之后的cookies:",s.cookies) # 主动会将响应的set-cookies添加到s对象当中。

# 第二种方式：自己主动获取 cookies，并在后续的请求当中，主动加上cookies
# 第二步：获取用户信息，直接使用对象调用get方法
userinfo_url = "https://www.ketangpai.com/UserApi/getUserInfo"
resp = s.get(userinfo_url)
print(resp.json())

方式二

import requests
# 第一步 - 登陆，得到cookies鉴权。
resp = requests.post(login_url,data=login_datas)
# 主动获取cookie
cookies = resp.cookies
print(cookies)

# 第二步： 获取用户信息
resp = requests.get(userinfo_url,cookies=cookies)
print(resp.json())

获取token

import requests


headers = {"X-Lemonban-Media-Type": "lemonban.v2"}

# 第一步：登陆，拿token
login_url = "http://api.lemonban.com/futureloan/member/login"
login_datas = {"mobile_phone": "13845467789", "pwd": "1234567890"}
resp = requests.post(login_url,json=login_datas,headers=headers)
# for key,value in resp.json().items():
#     print(key,value)
resp_dict = resp.json()
print(resp_dict)
token = resp_dict["data"]["token_info"]["token"]
member_id = resp_dict["data"]["id"]
print(token)

# 第二步：充值，将token添加请求头当中： Authorization：Bearer token值
headers["Authorization"] = "Bearer {}".format(token)
print(headers)
recharge_url = "http://api.lemonban.com/futureloan/member/recharge"
recharge_data = {"member_id": member_id, "amount": 2000}
# json=recharge_data，会将在请求头加上 "Content-Type": "application/json"
resp = requests.post(recharge_url,json=recharge_data,headers=headers)
print(resp.json())
