POST some JSON through TELNET

I am told to upload an image to a server by sending a JSON as a request.

JSON is sth like below:

{"action":"setMap","data":{"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}}

I do not know how to use TELNET to POST a JSON.

i guess i should write something like below

terminal>telnet my.ip.num.ber port

POST /setMap HTTP/1.1

but dont know how to continue.

Should i write 

DATA : {"action":"setMap","data":{"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}}

How can i get the JSON sent?

I can't understand why you want to use Telnet. Telnet can be useful to quickly test chatty protocols, and even if HTTP is chatty to some degree, it's very cumbersome to upload an image (plus, from the given service name, setMap, I guess the service doesn't really let you upload an image, but just insert a record in the database pointing to an image accessible on another service).

What you are asking is something like:

$ telnet example.com 80
> POST /setMap HTTP/1.1
> Host: www.example.com
> Content-Type: application/json; charset=utf-8
> Content-Length: 1234
> 
> {"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}
>

Note that it's just an example. You have to replace connection parameters (host, port), content-type, content-length and the actual JSON data - and this we can't know because depends on the actual service implementation.
