python连接consul
1. consul的KV操作
#!/usr/bin/python
# -*- coding: utf-8 -*-
# pip install python-consul
import consul
class Consul(object):
def __init__(self, host, port, token):
'''初始化，连接consul服务器'''
self._consul = consul.Consul(host, port, token=token)
def setConfig(self, key, value):
self._consul.kv.put(key, value)
def getConfig(self, key):
index, data = self._consul.kv.get(key)
print data['Value']
def deletConfig(self, key):
self._consul.kv.delete(key)
if __name__ == '__main__':
host = "192.168.1.200" # consul服务器的ip
port = 8500 # consul服务器对外的端口
token = "xxx"
# 连接consul
consul_client = Consul(host, port, token)
# 设置值,会在根目录下，创建test目录
consul_client.setConfig('test', 'ccc')
# 获取值
consul_client.getConfig('test')
# 删除值
consul_client.deletConfig('test')
2. consul服务注册
# -*- coding: UTF-8 -*-
# pip install python-consul
import consul
class Consul(object):
def __init__(self, host, port, token):
'''初始化，连接consul服务器'''
self._consul = consul.Consul(host, port, token=token)
def RegisterService(self, name, host, port, tags=None):
tags = tags or []
# 注册服务
self._consul.agent.service.register(
name,
name,
host,
port,
tags,
# 健康检查ip端口，检查时间：5,超时时间：30，注销时间：30s
check=consul.Check().tcp(host, port, "5s", "30s", "30s"))
def GetService(self, name):
services = self._consul.agent.services()
service = services.get(name)
if not service:
return None, None
addr = "{0}:{1}".format(service['Address'], service['Port'])
return service, addr
if __name__ == '__main__':
host = "192.168.1.120" # consul服务器的ip
port = "8500" # consul服务器对外的端口
token = "xxxx"
consul_client = Consul(host, port, token)
name = "loginservice"
host = "192.168.1.10"
port = 8500
consul_client.RegisterService(name, host, port)
check = consul.Check().tcp(host, port, "5s", "30s", "30s")
print(check)
res = consul_client.GetService("loginservice")
print(res)
