這篇文章主要介紹了python用requests實現http請求過程解析,文中通過示例程式碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

1. get

import requests

# 最簡單的get請求
r = requests.get(url)
print(r.status_code)
print(r.json())

# url 中?key=value&key=value
r = requests.get(url,params=params)

# form 表單
params = {"username":"name","password":"passw0rd"}
headers = {'Content-Type':'application/x-www-form-urlencoded'}
r = requests.get(url,params=params,headers=headers)

# 下載
r = requests.get(url)
r.raise_for_status()
with open(target,'wb') as f:
  for ch in r.iter_content(10000):
    result_file_size += f.write(ch)

2. post請求

data = {'name':'train','device':'CN0989'}
r = requests.post(url,json=data)

#上傳
files = {
    "file": (os.path.basename(filepath),open(filepath,"rb"),"application/zip")
}
print('POST %s'%url)
with open(filepath,'rb') as f:
  r = requests.post(url,files=files)

3. 登入

_session = requests.Session()

# login
url = '%s/login'%_basic_url
params = {"username":"admin","password":"admin"}
headers = {'Content-Type':'application/x-www-form-urlencoded'}
r = _session.post(url,headers=headers)

#做其他請求
r = _session.get(url)

_session.close()
