Project Wflink

Description

CMCC combine network process consists of a http server on the lan side and a coap-tls client on the wan side. The process named wflink.exe will handle common interfaces from both sides in the requests of two protocols(lan side using http and wan side using coap). At the same time, wflink.exe can also initiate a request to the remote coap server for registering/activating/logining/loginouting. The process named coapsrv.exe can simulate the conditions on coap requests from a remote server. On the other side, using a curl/postman/browser to send http requests is a cinsh.

Compile

Compile wflink

make

Compile test

make coapsrv.exe

Config file

Config path

}

Test

Preparation, change all "192.168.234.129" into your PC ip.

First, we start the remote coap server. Second, run our process. Third, try to send a demo reuqest to our process. Note: when the coap server simulates sending msg, fill the url with your coap client ip and port.

• ./coapsrv.exe -n 240 -v 7
• ./wflink.exe
• ./coapsrv.exe -rx "{"method": "get", "url":"192.168.234.129:6684/test/helloworld"}"
