title: POST some JSON through TELNET
body: <p>I am told to upload an image to a server by sending a JSON as a request.</p>
  
  <p>JSON is sth like below:</p>
  
  <pre><code>{"action":"setMap","data":{"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}}
  </code></pre>
  
  <p>I do not know how to use TELNET to POST a JSON.</p>
  
  <p>i guess i should write something like below</p>
  
  <pre><code>terminal&gt;telnet my.ip.num.ber port
  
  POST /setMap HTTP/1.1
  </code></pre>
  
  <p>but dont know how to continue.</p>
  
  <p>Should i write </p>
  
  <pre><code>DATA : {"action":"setMap","data":{"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}}
  </code></pre>
  
  <p>How can i get the JSON sent?</p>
