Python处理HTTP认证的常见方法

import requests
from requests.auth import HTTPBasicAuth
 
url = 'http://example.com/api/data'
username = 'your_username'
password = 'your_password'
 
response = requests.get(url, auth=HTTPBasicAuth(your_username, your_password))
print(response.text)

import requests
 
url = 'http://example.com/protected'
username = 'your_username'
password = 'your_password'
 
# 将用户名和密码进行Base64编码后放入请求头
auth_string=f'{your_username}:{your_password}'
b64_auth_string = base64.b64encode(auth_string.encode()).decode()
header={'Authorization': 'Basic ' + b64_auth_string}
 
# 使用requests的headers参数
response = requests.get(url, headers=header)
 
print(response.text)

import requests
from requests.auth import HTTPDigestAuth
 
url = 'http://example.com/protected'
username = 'your_username'
password = 'your_password'
 
# 使用HTTPDigestAuth
response = requests.get(url, auth=HTTPDigestAuth(username, password))
 
print(response.text)

import requests
 
url = 'http://example.com/protected'
token = 'your_token_here'
 
headers = {
    'Authorization': f'Bearer {token}'  # 或者使用其他认证机制，如 'Token {token}' 等
}
 
response = requests.get(url, headers=headers)
 
print(response.text)

pip install requests-oauthlib

from requests_oauthlib import OAuth2Session
 
client_id = 'your_client_id'
client_secret = 'your_client_secret'
redirect_uri = 'your_redirect_uri'
authorization_base_url = 'https://provider.com/oauth/authorize'
token_url = 'https://provider.com/oauth/token'
 
oauth = OAuth2Session(client_id=client_id, redirect_uri=redirect_uri)
authorization_url, state = oauth.authorization_url(authorization_base_url)
# 在这里，你可以打开authorization_url让用户登录并授权你的应用。之后，你将得到一个授权码（code）。
# 使用授权码获取token：
token = oauth.fetch_token(token_url, code='your_authorization_code')
# 现在，你可以使用这个token进行API调用：
response = oauth.get('http://api.example.com/protected')
print(response.text)
