从0开始学爬虫9之requests库的学习之环境搭建
Requests库的环境搭建
环境：python2.7.9版本
参考文档：http://2.python-requests.org/zh_CN/latest/
httpbin.org可以模拟http服务器，速度较慢，可以按照插件模拟http服务器
pip install gunicorn httpbin
gunnicorn不支持windows需要在linux系统中安装
启动http服务
[root@localhost ~]# gunicorn httpbin:app
[2019-07-17 22:08:50 +0000] [46575] [INFO] Starting gunicorn 19.9.0
[2019-07-17 22:08:50 +0000] [46575] [INFO] Listening at: http://127.0.0.1:8000 (46575)
[2019-07-17 22:08:50 +0000] [46575] [INFO] Using worker: sync
[2019-07-17 22:08:50 +0000] [46580] [INFO] Booting worker with pid: 46580
# 修改监听地址
[root@localhost ~]# gunicorn httpbin:app -b 0.0.0.0:8080
Requests是keep-alive可以重复利用一个连接
