Why do we need this WiFiWebServer_RTL8720 library

Features

This WiFiWebServer_RTL8720 library is a simple yet complete WebServer library for Realtek RTL8720DN, RTL8722DM and RTL8722CSM boards.

The functions are similar and compatible to those of ESP32 WebServer and ESP8266WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

This WiFiWebServer_RTL8720 library also provides high-level HTTP and WebSocket Client with the functions are similar and compatible to those of ArduinoHttpClient Library

The library provides supports to:

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

It is based on and modified from:

1. Ivan Grokhotkov's ESP8266WebServer
2. Ivan Grokhotkov's ESP32 WebServer
3. ArduinoHttpClient Library

The WiFiWebServer class found in WiFiWebServer_RTL8720.h header, is a simple web server that knows how to handle HTTP requests such as GET and POST and can only support one client at a time.

---

Currently Supported Boards

This WiFiWebServer_RTL8720 library currently supports these following boards:

1. Realtek RTL8720DN, RTL8722DM and RTL8722CSM

---

---

Prerequisites

1. Arduino IDE 1.8.19+ for Arduino.
2. Arduino AmebaD core 3.1.4+ for Realtek RTL8720DN, RTL8722DM and RTL8722CSM.
3. Functional-Vlpp library v1.0.2+ to use server's lambda function. To install. check

---

---

Installation

Use Arduino Library Manager

The best and easiest way is to use Arduino Library Manager. Search for WiFiWebServer_RTL8720, then select / install the latest version. You can also use this link for more detailed instructions.

Manual Install

1. Navigate to WiFiWebServer_RTL8720 page.
2. Download the latest release WiFiWebServer_RTL8720-main.zip.
3. Extract the zip file to WiFiWebServer_RTL8720-main directory
4. Copy the whole WiFiWebServer_RTL8720-main folder to Arduino libraries' directory such as ~/Arduino/libraries/.

VS Code & PlatformIO:

1. Install VS Code
2. Install PlatformIO
3. Install WiFiWebServer_RTL8720 library by using Library Manager. Search for WiFiWebServer_RTL8720 in Platform.io Author's Libraries
4. Please visit documentation for the other options and examples at Project Configuration File

---

---

Packages' Patches

1. For RTL8720DN boards using AmebaD core

To avoid compile error relating to PROGMEM, you have to copy the file Realtek AmebaD core pgmspace.h into Realtek AmebaD directory (~/.arduino15/packages/realtek/hardware/AmebaD/3.1.4/cores/ambd/avr/pgmspace.h).

Supposing the Realtek AmebaD core version is 3.1.4. This file must be copied into the directory:

• ~/.arduino15/packages/realtek/hardware/AmebaD/3.1.4/cores/ambd/avr/pgmspace.h

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied into the directory:

• ~/.arduino15/packages/realtek/hardware/AmebaD/x.yy.zz/cores/ambd/avr/pgmspace.h

Usage

Class Constructor

  WiFiWebServer server(80);

Creates the WiFiWebServer class object.

Parameters:

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

---

Basic Operations

Starting the server

  void begin();

Handling incoming client requests

  void handleClient();

Disabling the server

  void close();
  void stop();

Both methods function the same

Client request handlers

  void on();
  void addHandler();
  void onNotFound();
  void onFileUpload();	

Example:

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

Sending responses to the client

  void send();
  void send_P();

Parameters:

code - HTTP response code, can be 200 or 404, 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();
  int   args();
  bool  hasArg();

Function usage:

arg - get request argument value, use arg("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();
  int   headers();
  bool  hasHeader();

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

  bool authenticate();
  void requestAuthentication();

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 uri
  HTTPMethod    method(); // get the current method 
  WiFiClient    client(); // get the current client
  HTTPUpload&   upload(); // get the current upload
  
  void setContentLength(); // set content length
  void sendHeader(); // send HTTP header
  void sendContent(); // send content
  void sendContent_P(); 
  void collectHeaders(); // set the request headers to collect
  void serveStatic();
  
  size_t streamFile();

Debug

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

// Use this to output debug msgs to Serial
#define DEBUG_WIFI_WEBSERVER_PORT   Serial

// Debug Level from 0 to 4
#define _WIFI_LOGLEVEL_             1

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.

---

---

This WiFiWebServer_RTL8720 library currently supports these following boards:

1. Realtek RTL8720DN, RTL8722DM and RTL8722CSM

---

The library provides supports to:

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

---

---

Issues

Submit issues to: WiFiWebServer_RTL8720 issues

TO DO

1. Bug Searching and Killing
2. Add SSL/TLS Client

DONE

1. Add support to Realtek RTL8720DN, RTL8722DM and RTL8722CSM
2. Add High-level HTTP (GET, POST, PUT, PATCH, DELETE) and WebSocket Client
3. Fix bug related to usage of Arduino String
4. Optimize library code and examples by using reference-passing instead of value-passing.
5. Change from arduino.cc to arduino.tips in examples
6. Add astyle using allman style. Restyle the library
