python requests 示例_python用requests實作http請求代碼執行個體

這篇文章主要介紹了python用requests實作http請求過程解析,文中通過示例代碼介紹的非常詳細，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)

# 下載下傳

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, params=params, headers=headers)

#做其他請求

r = _session.get(url)

_session.close()
