# 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 * Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details. * In order to test the HTTPD server persistent sockets demo : 1. compile and burn the firmware `idf.py -p PORT flash` 2. run `idf.py -p PORT 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 \ \ \" * the provided test script first does a GET \hello and displays the response * the script does a POST to \echo with the user input \ 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 See the README.md file in the upper level 'examples' directory for more information about examples.
