为了在python中调用HTTP方法，可以使用以下库：
httplib
urllib
requests
可以使用PIP安装所有上述库，最简单的库是“requests”库。本文中使用的示例使用的是'requests'库。
pip install requests Collecting requests Downloading requests-2.23.0-py2.py3-none-any.whl (58 kB) |████████████████████████████████| 58 kB 2.4 MB/s Collecting certifi>=2017.4.17 Downloading certifi-2019.11.28-py2.py3-none-any.whl (156 kB) |████████████████████████████████| 156 kB 9.3 MB/s Collecting urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1 Downloading urllib3-1.25.8-py2.py3-none-any.whl (125 kB) |████████████████████████████████| 125 kB 10.6 MB/s Collecting chardet<4,>=3.0.2 Using cached chardet-3.0.4-py2.py3-none-any.whl (133 kB) Collecting idna<3,>=2.5 Downloading idna-2.9-py2.py3-none-any.whl (58 kB) |████████████████████████████████| 58 kB 4.1 MB/s Installing collected packages: certifi, urllib3, chardet, idna, requests Successfully installed certifi-2019.11.28 chardet-3.0.4 idna-2.9 requests-2.23.0 urllib3-1.25.8
import requests url = "http://www.recipepuppy.com/api/?i=onions,garlic&q=omelet" response = requests.get(url=url)print(response)print(response.text)
输出结果
