## Python Client For Apache Dubbo
## Achieve load balancing on the client side、auto discovery service function with Zookeeper
### Python calls the Dubbo interface's jsonrpc protocol
Please use dubbo-rpc-jsonrpc and configure protocol in Dubbo for jsonrpc protocol   
*Reference* [https://github.com/apache/incubator-dubbo-rpc-jsonrpc](https://github.com/apache/incubator-dubbo-rpc-jsonrpc)

### Installation

Download code  
python setup.py install  
pip install  
pip install dubbo-client==1.0.0b5
Git install  
pip install git+[http://git.dev.qianmi.com/tda/dubbo-client-py.git@1.0.0b5](http://git.dev.qianmi.com/tda/dubbo-client-py.git@1.0.0b5)  
or  
pip install git+[https://github.com/qianmiopen/dubbo-client-py.git@1.0.0b5](https://github.com/qianmiopen/dubbo-client-py.git@1.0.0b5)

### Load balancing on the client side, service discovery

Get the registration information of the service through the zookeeper of the registry.  
Dubbo-client-py supports configuring multiple zookeeper service addresses. 
"host":"192.168.1.183:2181,192.168.1.184:2181,192.168.1.185:2181"  
Then the load balancing algorithm is implemented by proxy, and the server is called.    
Support Version and Group settings.
### Example
	    config = ApplicationConfig('test_rpclib')
	    service_interface = 'com.ofpay.demo.api.UserProvider'
	    #Contains a connection to zookeeper, which needs caching.
	    registry = ZookeeperRegistry('192.168.59.103:2181', config)
	    user_provider = DubboClient(service_interface, registry, version='1.0')
	    for i in range(1000):
        try:
            print user_provider.getUser('A003')
            print user_provider.queryUser(
                {u'age': 18, u'time': 1428463514153, u'sex': u'MAN', u'id': u'A003', u'name': u'zhangsan'})
            print user_provider.queryAll()
            print user_provider.isLimit('MAN', 'Joe')
            print user_provider('getUser', 'A005')

        except DubboClientError, client_error:
            print client_error
        time.sleep(5)
	
### TODO
Optimize performance, minimize the impact of service upper and lower lines.  
Support Retry parameters  
Support weight call  
Unit test coverage
