## 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](http://alibaba.github.io/dubbo-doc-static/Telnet+Command+Reference-zh-showComments=true&showCommentArea=true.htm) telnet 调用示例： ```python $ telnet 172.17.103.110 9097 Trying 172.17.103.110... Connected to 172.17.103.110.

待改进 * 进行多个项目的实验，增加异常处理 ## 参考资料 -   [本文最新版本地址](https://china-testing.github.io/python3_lib_dubbo.html) -   [本文涉及的python测试开发库](https://github.com/china-testing/python-api-tesing) 谢谢点赞！ -   [本文相关海量书籍下载](https://github.com/china-testing/python-api-tesing/blob/master/books.md) -   [本文源码地址](https://github.com/china-testing/python-api-tesing/tree/master/python3_libraries/_dubbo)
