Features

ThisWebServer_ESP32_SC_W6100 library is a simple yet complete WebServer wrapper library forESP32_S2/S3/C3-based boards usingLwIP W6100 Ethernet. The functions are similar and compatible to those ofESP32 WebServer andESP8266WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

ThisWebServer_ESP32_SC_W6100 library also provides high-levelHTTP(S), MQTT(S) and WebSockets Client by using the functions from ESP32'sHTTPClient Library

The library provides these features:

  1. TCP Server and Client
  2. UDP Server and Client
  3. HTTP(S) Server and Client
  4. HTTP(S) GET and POST requests, provides argument parsing, handles one client at a time.
  5. High-level HTTP(S) (GET, POST, PUT, PATCH, DELETE), MQTT(S) and WebSocket Client.

Library is providing similar functions to:

  1. Ivan Grokhotkov's ESP32 WebServer
  2. HTTPClient Library

Installation

Use Arduino Library Manager

The best and easiest way is to useArduino Library Manager. Search forWebServer_ESP32_SC_W6100, then select / install the latest version.You can also use this linkarduino-library-badge for more detailed instructions.

Manual Install

  1. Navigate toWebServer_ESP32_SC_W6100 page.
  2. Download the latest releaseWebServer_ESP32_SC_W6100-main.zip.
  3. Extract the zip file toWebServer_ESP32_SC_W6100-main directory
  4. Copy the wholeWebServer_ESP32_SC_W6100-main folder to Arduino libraries' directory such as~/Arduino/libraries/.

VS Code & PlatformIO:

  1. InstallVS Code
  2. InstallPlatformIO
  3. InstallWebServer_ESP32_SC_W6100 library by usingLibrary Manager. Search for WebServer_ESP32_SC_W6100 inPlatform.io Author's Libraries
  4. Use includedplatformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples atProject Configuration File

Libraries' Patches

1. For fixing ESP32 compile error

To fixESP32 compile error, just copy the following file into theESP32 cores/esp32 directory (e.g. ./arduino-1.8.19/hardware/espressif/cores/esp32) to overwrite the old file:

HOWTO FixMultiple Definitions Linker Error

The current library implementation, usingxyz-Impl.h instead of standardxyz.cpp, possibly creates certainMultiple Definitions Linker error in certain use cases.

You can include this.hpp file

// Can be included as many times as necessary, without `Multiple Definitions` Linker Error#include"WebServer_ESP32_SC_W6100.hpp"//https://github.com/khoih-prog/WebServer_ESP32_SC_W6100

in many files. But be sure to use the following.h filein just 1.h,.cpp or.ino file, which mustnot be included in any other file, to avoidMultiple Definitions Linker Error

// To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error#include"WebServer_ESP32_SC_W6100.h"//https://github.com/khoih-prog/WebServer_ESP32_SC_W6100

Check the newmultiFileProject example for aHOWTO demo.

HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)

Please have a look atESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.

1. ESP32 has 2 ADCs, named ADC1 and ADC2

2. ESP32 ADCs functions

  • ADC1 controls ADC function for pinsGPIO32-GPIO39
  • ADC2 controls ADC function for pinsGPIO0, 2, 4, 12-15, 25-27

3. ESP32 WiFi uses ADC2 for WiFi functions

Look in fileadc_common.c

In ADC2, there're two locks used for different cases:

  1. lock shared with app and Wi-Fi:ESP32:When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed.ESP32S2:The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.

  2. lock shared between tasks:when several tasks sharing the ADC2, we want to guaranteeall the requests will be handled.Since conversions are short (about 31us), app returns the lock very soon,we use a spinlock to stand there waiting to do conversions one by one.

adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.

  • In order to useADC2 for other functions, we have toacquire complicated firmware locks and very difficult to do
  • So, it's not advisable to useADC2 with WiFi/BlueTooth (BT/BLE).
  • UseADC1, and pins GPIO32-GPIO39
  • If somehow it's a must to use those pins serviced byADC2 (GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use thefix mentioned at the end ofESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).

Usage

Class Constructor

WebServerserver(80);

Creates theWebServer_ESP32_SC_W6100 class object.

Parameters:

host port number:int port (default is the standard HTTP port 80)

Basic Operations

Starting the server

voidbegin();

Handling incoming client requests

voidhandleClient();

Disabling the server

voidclose();voidstop();

Both methods function the same

Client request handlers

voidon();voidaddHandler();voidonNotFound();voidonFileUpload();

Example:

server.on("/", handlerFunction);server.onNotFound(handlerFunction);// called when handler is not assignedserver.onFileUpload(handlerFunction);// handle file uploads

Sending responses to the client

voidsend();voidsend_P();

Parameters:

code - HTTP response code, can be200 or404, etc.

content_type - HTTP content type, like"text/plain" or"image/png", etc.

content - actual content body

Advanced Options

Getting information about request arguments

const String &arg();const String &argName();intargs();boolhasArg();

Function usage:

arg - get request argument value, usearg("plain") to get POST body

argName - get request argument name

args - get arguments count

hasArg - check if argument exist

Getting information about request headers

const String &header();const String &headerName();const String &hostHeader();intheaders();boolhasHeader();

Function usage:

header - get request header value

headerName - get request header name

hostHeader - get request host header if available, else empty string

headers - get header count

hasHeader - check if header exist

Authentication

boolauthenticate();voidrequestAuthentication();

Function usage:

authenticate - server authentication, returns true if client is authenticated else false

requestAuthentication - sends authentication failure response to the client

Example Usage:

if(!server.authenticate(username, password)){  server.requestAuthentication();}

Other Function Calls

const String &uri();// get the current uriHTTPMethodmethod();// get the current methodWiFiClientclient();// get the current clientHTTPUpload &upload();// get the current uploadvoidsetContentLength();// set content lengthvoidsendHeader();// send HTTP headervoidsendContent();// send contentvoidsendContent_P();voidcollectHeaders();// set the request headers to collectvoidserveStatic();size_tstreamFile();

Debug

Debug is enabled by default on Serial. Debug Level from 0 to 4. To disable, change theETHERNET_WEBSERVER_LOGLEVEL to 0

// Use this to output debug msgs to Serial#defineDEBUG_ETHERNET_WEBSERVER_PORT       Serial// Use this to disable all output debug msgs// Debug Level from 0 to 4#define_ETHERNET_WEBSERVER_LOGLEVEL_0

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, applying Libraries' Patches, Packages' Patches or this library latest version.
