利用python脚本和telnet调试dubbo接口

#-*- coding: utf-8 -*-

import dubbo_telnet
import json
Host = ‘192.168.0.1‘  # Doubble服务器IP
Port = 9036  # Doubble服务端口

# 初始化dubbo对象
conn = dubbo_telnet.connect(Host, Port)

# 设置telnet连接超时时间
conn.set_connect_timeout(10)

# 设置dubbo服务返回响应的编码
conn.set_encoding(‘gbk‘)

# 显示服务列表
print conn.do("ls")

# 显示指定服务的方法列表
print conn.do("ls XXXService")

# 方法调用
interface = ‘XXXService‘
method = ‘userinfo‘
param = user_id
result = conn.invoke(interface, method, param)

print json.dumps(result, sort_keys=True, indent=4, separators=(‘,‘, ‘: ‘), skipkeys=True, ensure_ascii=False)
