Simple HTTPD Server Example

The Example consists of HTTPD server demo with demostration of URI handling : 1. URI \hello for GET command returns "Hello World!" message 2. URI \echo for POST command echoes back the POSTed message

• Configure the project using "make menuconfig" and goto :

  • Example Configuration ->
    1. WIFI SSID: WIFI network to which your PC is also connected to.
    2. WIFI Password: WIFI password

• In order to test the HTTPD server persistent sockets demo :

  1. compile and burn the firmware "make flash"
  2. run "make monitor" and note down the IP assigned to your ESP module. The default port is 80
  3. test the example :
     • run the test script : "python2 scripts/client.py <IP> <port> <MSG>"
       • the provided test script first does a GET \hello and displays the response
       • the script does a POST to \echo with the user input <MSG> and displays the response
     • or use curl (asssuming IP is 192.168.43.130):
       1. "curl 192.168.43.130:80/hello" - tests the GET "\hello" handler
       2. "curl -X POST --data-binary @anyfile 192.168.43.130:80/echo > tmpfile"
          • "anyfile" is the file being sent as request body and "tmpfile" is where the body of the response is saved
          • since the server echoes back the request body, the two files should be same, as can be confirmed using : "cmp anyfile tmpfile"
       3. "curl -X PUT -d "0" 192.168.43.130:80/ctrl" - disable /hello and /echo handlers
       4. "curl -X PUT -d "1" 192.168.43.130:80/ctrl" - enable /hello and /echo handlers
