ESP32-cam http-server streaming

This repo is based in the HTTP-Server example in tho the esp-idf, and in the streaming example of the esp32-cam repository.

  • Open the project configuration menu (idf.py menuconfig) to configure Wi-Fi or Ethernet.

  • For esp32-camera enable the support for external SPRAM.

  • 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 : "python 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

  • If the server log shows "httpd_parse: parse_block: request URI/header too long", especially when handling POST requests, then you probably need to increase HTTPD_MAX_REQ_HDR_LEN, which you can find in the project configuration menu (idf.py menuconfig): Component config -> HTTP Server -> Max HTTP Request Header Length

  • Access to the camera streaming in the /cam url.
