Hi Supun & Himasha,
The AJAX call for the "
https://192.168.1.2:9443/bpmn-explorer/send?req=/bpmn/runtime/tasks/15048/attachments
<https://www.google.com/url?q=https%3A%2F%2F192.168.1.2%3A9443%2Fbpmn-explorer%2Fsend%3Freq%3D%2Fbpmn%2Fruntime%2Ftasks%2F15048%2Fattachments&sa=D&sntz=1&usg=AFQjCNGtlHGgHQIkEKjRr4tnkFlGAySrqw>
" resolves to a controller called "communication.jag" [1] inside the
"bpmn-explorer" jaggery app.
1. localIP = process.getProperty('carbon.local.ip'),
2. httpPort = process.getProperty('mgt.transport.http.port'),
3. httpUrl = "http://"+localIP+":"+httpPort,
4. //....
5. run = request.getMethod();
6. if(run == "POST"){
7. req = request.getParameter("req");
8. url = req;
9. data = request.getContent();
10. result = post( httpUrl + url, JSON.stringify(data), headers, "text");
11. log.debug("BPMN Rest POST results: " + result);
12. }
13. //....
1. This controller passes the call for the service url mentioned in "req"
parameter. httpUrl is always HTTP(not HTTPs) and port is 9763(not 9443).
Please refer above line #3; this is the reason for getting
"*http://192.168.1.2:9763
<http://192.168.1.2:9763>*" instead of "*https://192.168.1.2:9443
<https://192.168.1.2:9443>*".
2. The reason for getting "null" for "req" parameter is quite unclear(Refer
above line #7). Try to pass it as a "form parameter" instead of "query
parameter" for the "POST" request[2].
Thank you
