This appears to be a problem with POSTMAN rest client you are using.
I’m seeing the same with POSTMAN 0.8.4.12 and it’s only in JSON/Pretty – if you
switch to JSON/RAW it shall show correct dpid.
POSTMAN 1.0.8 does not have the problem.

Dear all
A problem encountered when I use the ryu-controller,the dpid of the SDN
switch displayed at ryu-controller sever is not the same as using REST
API(/stats/switches) to get ,the detail as next:
After running ryu-controller sever and point the SDN switch to the
controller,I can see the packet in data at the ryu-controller sever,the data
is:"packet in 6790944927334400461 48:5a:b1:36:45:8d ff:ff:ff:ff:ff:ff 1".
From the data we can get the dpid of the SDN switch is
6790944927334400461.But when I using the REST API to get the SDN information,I
get another dpid 6790944927334400000 .And there is only a SDN switch have
pointed to the ryu-controller.You also can see the next picture.

From this picture we can see the dpid of the SDN switch
is 6790944927334400461.

From this picture we can see the dpid is
6790944927334400000,and this dpid is wrong.The true dpid is the one displayed
on ryu-controller server.
I have afflict by this problem for a long time,if anyone can give me some
help,thanks very much!
Best Regards
PanCheng
