Why do we need this Async AsyncHTTPRequest_Generic library

Features

  1. Asynchronous HTTP Request library for ESP8266, including ESP32-S2 (ESP32-S2 Saola, AI-Thinker ESP-12K, etc.) using built-in WiFi, WT32_ETH01 (ESP32 + LAN8720), ESP32_ENC (ESP32 + LwIP ENC28J60) and STM32 boards using LAN8720 or built-in LAN8742A Ethernet.
  2. Providing a subset of HTTP.
  3. Relying on on ESPAsyncTCP for ESP8266, AsyncTCP for ESP32 using built-in WiFi
  4. Relying on STM32duino LwIP/STM32duino STM32Ethernet/STM32AsyncTCP for STM32 using LAN8720 or built-in LAN8742A Ethernet.
  5. Methods similar in format and usage to XmlHTTPrequest in Javascript.

Supports

  1. GET, POST, PUT, PATCH, DELETE and HEAD
  2. Request and response headers
  3. Chunked response
  4. Single String response for short (<~5K) responses (heap permitting).
  5. Optional onData callback.
  6. Optional onReadyStatechange callback.

Principles of operation

This library adds a simple HTTP layer on top of the ESPAsyncTCP/AsyncTCP/STM32 AsyncTCP library to facilitate REST communication from a Client to a Server. The paradigm is similar to the XMLHttpRequest in Javascript, employing the notion of a ready-state progression through the transaction request.

Synchronization can be accomplished using callbacks on ready-state change, a callback on data receipt, or simply polling for ready-state change. Data retrieval can be incremental as received, or bulk retrieved when the transaction completes provided there is enough heap to buffer the entire response.

The underlying buffering uses a new xbuf class. It handles both character and binary data. Class xbuf uses a chain of small (64 byte) segments that are allocated and added to the tail as data is added and deallocated from the head as data is read, achieving the same result as a dynamic circular buffer limited only by the size of heap. The xbuf implements indexOf and readUntil functions.

For short transactions, buffer space should not be an issue. In fact, it can be more economical than other methods that use larger fixed length buffers. Data is acked when retrieved by the caller, so there is some limited flow control to limit heap usage for larger transfers.

Request and response headers are handled in the typical fashion.

Chunked responses are recognized and handled transparently.

This library is based on, modified from:

  4. Use included platformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at Project Configuration File

Packages' Patches

1. For STM32 boards to use LAN8720

For Generic STM32F4 series boards, such as STM32F407VE, using LAN8720, please use STM32 core v2.2.0 as breaking core v2.3.0 creates the compile error.

To use LAN8720 on some STM32 boards

  • Nucleo-144 (F429ZI, NUCLEO_F746NG, NUCLEO_F746ZG, NUCLEO_F756ZG)
  • Discovery (DISCO_F746NG)
  • STM32F4 boards (BLACK_F407VE, BLACK_F407VG, BLACK_F407ZE, BLACK_F407ZG, BLACK_F407VE_Mini, DIYMORE_F407VGT, FK407M1)

you have to copy the files stm32f4xx_hal_conf_default.h and stm32f7xx_hal_conf_default.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.2.0/system) to overwrite the old files.

Supposing the STM32 stm32 core version is 2.2.0. These files must be copied into the directory:

  • ~/.arduino15/packages/STM32/hardware/stm32/2.2.0/system/STM32F4xx/stm32f4xx_hal_conf_default.h for STM32F4.
  • ~/.arduino15/packages/STM32/hardware/stm32/2.2.0/system/STM32F7xx/stm32f7xx_hal_conf_default.h for Nucleo-144 STM32F7.

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

  • ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/system/STM32F4xx/stm32f4xx_hal_conf_default.h
  • `~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/system/STM32F7xx/stm32f7xx_hal_conf_default.h

2. For STM32 boards to use Serial1

To use Serial1 on some STM32 boards without Serial1 definition (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8, etc.) boards, you have to copy the files STM32 variant.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.3.0). You have to modify the files corresponding to your boards, this is just an illustration how to do.

Supposing the STM32 stm32 core version is 2.3.0. These files must be copied into the directory:

  • ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.
  • ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/NUCLEO_L053R8/variant.h for Nucleo-64 NUCLEO_L053R8.

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

  • ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/NUCLEO_F767ZI/variant.h
  • ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/NUCLEO_L053R8/variant.h

Note for Platform IO using ESP32 LittleFS

In Platform IO, to fix the error when using LittleFS_esp32 v1.0.6 for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line

from

//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

to

#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

It's advisable to use the latest LittleFS_esp32 v1.0.5+ to avoid the issue.

Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'

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

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

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

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

Check the new multiFileProject example for a HOWTO demo.

Have a look at the discussion in Different behaviour using the src_cpp or src_h lib #80

Note for Platform IO using ESP32 LittleFS

In Platform IO, to fix the error when using LittleFS_esp32 v1.0 for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line

from

//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

to

#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

It's advisable to use the latest LittleFS_esp32 v1.0.5+ to avoid the issue.

Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'

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 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

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 to work with ESP32 WiFi/BlueTooth (BT/BLE).

Debug

Debug is enabled by default on Serial.

You can also change the debugging level from 0 to 4

#define ASYNC_HTTP_DEBUG_PORT           Serial

// Use from 0 to 4. Higher number, more debugging messages and memory usage.
#define _ASYNC_HTTP_LOGLEVEL_           1

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the ESP32 / ESP8266 / STM32 core for Arduino.

Sometimes, the library will only work if you update the ESP32 / ESP8266 / STM32 core to the latest version because I am using newly added functions.
