    zookeeper给python提供了几种API

    具体代码请参考我的Github。

    1.引用kazoo lib

    API DOC:

    http://kazoo.readthedocs.io/en/latest/install.html

    Code:


    # -*- coding:utf-8 -*-
    __author__ = 'yangxin'
    
    from kazoo.client import KazooClient
    
    class PyZooConn(object):
        # init function include connection method
        def __init__(self):
            self.zk = KazooClient(hosts='localhost:2182')
            self.zk.start()
    
        # get node data
        def get_data(self, param):
            result = self.zk.get(param)
            print result
    
        # create a node and input a value in this node
        def create_node(self, node, value):
            self.zk.create(node, value)
    
    
        # close the connection
        def close(self):
            self.zk.stop()
    
        '''
        Hypothesis there is a bunch of methods here haha :)
        '''
    
    if __name__ == '__main__':
        pz = PyZooConn()
        pz.create_node("/test", "a value")
        pz.get_data("/test/")
        pz.close()


    2.引用 zookeeper

    Code:


    # -*- coding:utf-8 -*-
    __author__ = 'yangxin'
    import zookeeper as zoo
    import os
    
    
    class PyZookeeper(object):
        def __init__(self):
            zk_address = os.environ.get("192.168.1.1:2181")
            self.zk = zoo.init(zk_address)
    
        def create_node(self, node, key,value):
            self.zk.create(node, key, value)
    
        def get(self, node, key):
            self.zk.get("/test", key)
    
        '''
        Hypothesis there is a bunch of methods here haha :)
        '''
    
    if __name__ == '__main__':
        py_zoo = PyZookeeper()
        py_zoo.create_node("","", "")
        py_zoo.get("","")
