一、python查询功能代码
1、查询修改配置文件
global
log 127.0.0.1 local2
daemon
maxconn 256
log 127.0.0.1 local2 info
defaults
log global
mode http
timeout connect 5000ms
timeout client 50000ms
timeout server 50000ms
option dontlognull listen stats :8888
stats enable
stats uri /admin
stats auth admin:1234 frontend simon.org
bind 0.0.0.0:80
option httplog
option httpclose
option forwardfor
log global
acl www hdr_reg(host) -i www.simon.org
use_backend www.simon.org if www backend www.simon1.org
server 101.1000.7.9 101.1000.7.9 weight 20 maxconn 30
server 2.2.2.7 2.2.2.7 weight 30 maxconn 4000
server 10.10.10.1 10.10.10.1 weight 22 maxconn 2000
server 2.2.2.5 2.2.2.5 weight 30 maxconn 4000 backend www.simon2.org
server 3.3.3.3 3.3.3.3 weight 20 maxconn 3000
backend www.simon20.org
server 10.10.0.10 10.10.0.10 weight 9999 maxconn 33333333333
haproxy.conf
二、实现代码如下

break

r_list.append(line.strip())

print(line)
return r_list

with open(filename, 'r') as read_file, \

continue

else:

return
else:
