The functions are similar and compatible to those of [`ESP32 WebServer`](https://github.com/espressif/arduino-esp32/tree/master/libraries/WebServer) and [`ESP8266WebServer`](https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266WebServer) libraries to make life much easier to port sketches from ESP8266/ESP32. This [**WebServer_ESP32_W5500 library**](https://github.com/khoih-prog/WebServer_ESP32_W5500) also provides high-level **HTTP(S), MQTT(S) and WebSockets Client** by using the functions from ESP32's [**HTTPClient Library**](https://github.com/espressif/arduino-esp32/tree/master/libraries/HTTPClient) 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](https://github.com/espressif/arduino-esp32/tree/master/libraries/WebServer) 2.

Please visit documentation for the other options and examples at [Project Configuration File](https://docs.platformio.org/page/projectconf.html) --- --- ### Libraries' Patches #### 1. For fixing ESP32 compile error To fix [`ESP32 compile error`](https://github.com/espressif/arduino-esp32), just copy the following file into the [`ESP32`](https://github.com/espressif/arduino-esp32) cores/esp32 directory (e.g. ./arduino-1.8.19/hardware/espressif/cores/esp32) to overwrite the old file: - [Server.h](LibraryPatches/esp32/cores/esp32/Server.h) --- --- ### HOWTO Fix `Multiple Definitions` Linker Error The current library implementation, using `xyz-Impl.h` instead of standard `xyz.cpp`, possibly creates certain `Multiple Definitions` Linker error in certain use cases. You can include this `.hpp` file ```cpp // Can be included as many times as necessary, without `Multiple Definitions` Linker Error #include "WebServer_ESP32_W5500.hpp" //https://github.com/khoih-prog/WebServer_ESP32_W5500 ``` in many files. But be sure to use the following `.h` file **in just 1 `.h`, `.cpp` or `.ino` file**, which must **not be included in any other file**, to avoid `Multiple Definitions` Linker Error ```cpp // To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error #include "WebServer_ESP32_W5500.h" //https://github.com/khoih-prog/WebServer_ESP32_W5500 ``` Check the new [**multiFileProject** example](examples/multiFileProject) for a `HOWTO` demo. --- --- ### HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE) Please have a look at [**ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example**](https://github.com/khoih-prog/ESP_WiFiManager/issues/39) 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 pins **GPIO32-GPIO39** - `ADC2` controls ADC function for pins **GPIO0, 2, 4, 12-15, 25-27** #### 3.. ESP32 WiFi uses ADC2 for WiFi functions Look in file [**adc_common.c**](https://github.com/espressif/esp-idf/blob/master/components/driver/adc_common.c#L61) > 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 guarantee > all 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 use `ADC2` for other functions, we have to **acquire complicated firmware locks and very difficult to do** - So, it's not advisable to use `ADC2` with WiFi/BlueTooth (BT/BLE). - Use `ADC1`, and pins GPIO32-GPIO39 - If somehow it's a must to use those pins serviced by `ADC2` (**GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27**), use the **fix mentioned at the end** of [**ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example**](https://github.com/khoih-prog/ESP_WiFiManager/issues/39) to work with ESP32 WiFi/BlueTooth (BT/BLE). --- --- #### Usage #### Class Constructor ```cpp WebServer server(80); ``` Creates the WebServer_ESP32_W5500 class object. *Parameters:* host port number: ``int port`` (default is the standard HTTP port 80) #### Basic Operations **Starting the server** ```cpp void begin(); ``` **Handling incoming client requests** ```cpp void handleClient(); ``` **Disabling the server** ```cpp void close(); void stop(); ``` Both methods function the same **Client request handlers** ```cpp void on(); void addHandler(); void onNotFound(); void onFileUpload(); ``` Example: ```cpp server.on("/", handlerFunction); server.onNotFound(handlerFunction); // called when handler is not assigned server.onFileUpload(handlerFunction); // handle file uploads ``` **Sending responses to the client** ```cpp 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** ```cpp 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** ```cpp 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** ```cpp 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:` ```cpp if(!server.authenticate(username, password)) { server.requestAuthentication(); } ``` #### Other Function Calls ```cpp 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(); ``` --- --- ### How to connect W5500 to ESP32 You can change the `INT` pin to another one. Default is `GPIO4` ```cpp // Must connect INT to GPIOxx or not working #define INT_GPIO 4 ``` --- #### W5500 `FULL_DUPLEX, 100Mbps`
