python项目通过使用jenkinsapi长途控制jenkins
jenkinsapi使用的长途连接要领是requests包，requests包又使用了urllib3，urllib3又引用了httplib。
"""
urllib3 - Thread-safe connection pooling and re-using.
"""
requests使用连接池机制，，连接池
http的通过设置
Connection:keep-alive
的header头来表白是长连接，通过传输层tcp的长连接实现
短连接会占用较多的端口
socket就是源IP、源端口、协议(scheme)、目的IP、目的端口的五元组
import requests sess = requests.Session() adapter = requests.adapters.HTTPAdapter(pool_connections=100, pool_maxsize=100) sess.mount(‘‘, adapter) resp = sess.get("/mypage")requests的默认连接池是10个，每个连接池的最大连接数默认也是10个
