python telnet server_python工具库介绍-dubbo：通过telnet接口访问dubbo服务-优快云博客

简介

dubbo服务发布之后，我们可以利用telnet命令进行调试、管理。更多资料参见 Telnet命令参考手册

telnet 调用示例：

$ telnet 172.17.103.110 9097

Trying 172.17.103.110...

Connected to 172.17.103.110.

Escape character is '^]'.

dubbo>ls com.oppo.sso.service.onekey.IOnekeyRegister

dubbo>invoke com.oppo.sso.service.onekey.IOnekeyRegister.register({"applicationKey":"mac","imei":"","mobile":"13244448888","createIP":"127.0.0.1","createBy":"172.17.0.1"})

import json

import socket

class Dubbo(telnetlib.Telnet):

prompt = 'dubbo>'

coding = 'utf-8'

def __init__(self, host=None, port=0,

timeout=socket._GLOBAL_DEFAULT_TIMEOUT):

super().__init__(host, port)

self.write(b'\n')

return data

service_name, method_name, json.dumps(arg))

self.command(Dubbo.prompt, command_str)

data = self.command(Dubbo.prompt, "")

data = json.loads(data.decode(Dubbo.coding,

errors='ignore').split('\n')[0].strip())

return data

if __name__ == '__main__':

conn = Dubbo('172.17.103.110', 9097)

json_data = {

"applicationKey":"mac",

"imei":"",

"mobile":"13244448888",

"createIP":"127.0.0.1",

"createBy":"172.17.0.1"

}

result = conn.invoke(

"register",

)

print(result)

执行结果：
