python项目通过使用jenkinsapi远程控制jenkins

jenkinsapi使用的远程连接方法是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

的header头来表明是长连接，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('http://', adapter)
resp = sess.get("/mypage")

requests常见的一些错误提示有：

• Failed to establish a new connection:
• Connection pool is full, discarding connection

The newest version of Requests does in fact keep the TCP connection alive after your request.. If you do want your TCP connections to close, you can just configure the requests to not use keep-alive.

s = requests.session()
s.config['keep_alive'] = False
s.keep_alive = False

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
