brief introduction
After dubbo service is released, we can use telnet command to debug and manage. For more information, see Telnet Command Reference Manual
telnet call example:
$ 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 register dubbo>invoke com.oppo.sso.service.onekey.IOnekeyRegister.register({"applicationKey":"mac","imei":"","mobile":"13244448888","createIP":"127.0.0.1","createBy":"172.17.0.1"}) {"configCountry":null,"userIdLong":0,"appPackage":null,"appVersion":null,"accountName":null,"romVersion":null,"resultCode":3001,"thirdStatus":null,"registerType":0,"sendChannel":null,"operator":null,"manufacturer":null,"password":null,"osVersion":null,"lock":false,"model":null,"visitorLocked":false,"OK":false,"brand":null,"email":null,"createIP":null,"deny":false,"encryptEmail":null,"sessionKey":null,"thirdId":null,"passwordOriginal":null,"mobile":null,"applicationKey":null,"thirdpartyOk":false,"userAgent":null,"userName":null,"resultDesc":"App does not exist","userId":0,"encryptMobile":null,"emailStatus":null,"createBy":null,"freePwd":false,"changeTimes":0,"createTime":null,"mobileStatus":null,"oldLock":false,"codeTimeout":null,"lastUpdate":null,"imei":null,"sessionTimeout":0,"sdkVersion":null,"networkID":0,"status":null} elapsed: 98 ms. dubbo>
Python implementation

To be improved
- Experiment with multiple projects and increase exception handling
