Doge is a Python RPC framework like [Alibaba Dubbo](http://dubbo.io/) and [Weibo Motan](https://github.com/weibocom/motan).

## Features

![doge](https://camo.githubusercontent.com/51ff9a1d5530f269f3074e9172483acf14c73eb8/687474703a2f2f6e2e73696e61696d672e636e2f746563682f7472616e73666f726d2f32303136303531302f4a7458792d66787279686875323338323938372e6a7067)

- 服务治理, 服务注册, 服务发现
- 高可用策略, failover, backupRequestHA
- 负载均衡策略, RandomLB, RoundrobinLB
- 限流策略, gevent Pool

## Quick Start

### Installation

```sh
pip install dogerpc
```

你可以在[examples](https://github.com/zhu327/doge/tree/master/examples)找到以下实例

### Doge server

1. 新建server端配置文件

```javascript
{
"registry": { // 注册中心
"protocol": "etcd", // 注册协议, 支持 etcd 与 direct, 默认 etcd
"host": "127.0.0.1", // 注册中心 host
"port": 2379, // 注册中心 port
// "address": "127.0.0.1:2379,127.0.0.1:4001", // 注册中心地址, 如果有etcd集群, 可配置多个node
"ttl": 10 // etcd注册ttl, 用于server的心跳检查, 默认10s
},
"service": {
"name": "test", // 服务名称
"node": "n1", // 节点名称
"host": "127.0.0.1", // 服务暴露ip
"port": 4399, // 服务暴露port
"limitConn": 100 // 服务最大连接数, 可选, 默认不限制
}
}
```

2. 定义RPC methods类, 启动服务

```python
# coding: utf-8

from gevent import monkey
monkey.patch_socket() # 依赖gevent

import logging
logging.basicConfig(level=logging.DEBUG)

from doge.rpc.server import new_server


# 定义rpc方法类
class Sum(object):
def sum(self, x, y):
return x + y


if __name__ == '__main__':
server = new_server('server.json') # 基于配置文件实例化server对象
server.load(Sum) # 加载暴露rpc方法类
server.run() # 启动服务并注册节点信息到注册中心
```

### Doge client

1. 新建client端配置文件

```javascript
{
"registry": { // 注册中心
"protocol": "etcd", // 注册协议, 支持 etcd 与 direct, 默认 etcd
"host": "127.0.0.1", // 注册中心 host
"port": 2379, // 注册中心 port
// "address": "127.0.0.1:2379,127.0.0.1:4001", // 注册中心地址, 如果有etcd集群, 可配置多个node
"ttl": 10 // etcd注册ttl, 用于server的心跳检查, 默认10s
},
"refer": {
"haStrategy": "failover", // 高可用策略, 支持 failover backupRequestHA, 默认failover
"loadbalance": "RoundrobinLB", // 负载均衡策略, 支持 RandomLB RoundrobinLB, 默认RoundrobinLB
}
}
```

2. 创建client并call远程方法

```python
# coding: utf-8

from __future__ import print_function

from gevent import monkey
monkey.patch_socket()

import logging
logging.basicConfig(level=logging.DEBUG)

from doge.rpc.client import Cluster

if __name__ == '__main__':
cluster = Cluster('client.json') # 基于配置文件实例化Cluster对象
client = cluster.get_client("test") # 获取服务名对应的Client对象
print(client.call('sum', 1, 2)) # 远程调用服务Sum类下的sum方法
```

## doge json gateway

基于Bottle实现的json rpc gateway
