khoih-prog / AsyncHTTPSRequest_Generic

Simple Async HTTPS Request library, supporting GET, POST, PUT, PATCH, DELETE and HEAD, on top of AsyncTCP_SSL library for ESP32 (including ESP32_S2, ESP32_S3 and ESP32_C3), WT32_ETH01 (ESP32 + LAN8720). Supporting in the future for RP2040W, ESP8266, Portenta_H7, STM32 with built-in LAN8742A Ethernet, etc. Now you can send HTTP / HTTPS requests to multiple addresses and receive responses from them

I filled up my wifi ssid/pass in example but I did not get response, only:

I'm sorry I couldn't duplicate and everything is OK here. You have to check your network / router settings and turn on better debug option to understand what's really happening there. 

#define _ASYNC_TCP_SSL_LOGLEVEL_    4
#define _ASYNC_HTTPS_LOGLEVEL_      4

I'll investigate only after you'd prove this is a bug of the library.

I now have a functional sending of requests. I found that in order to send another request, I have to wait for the previous one to reply. I have solved this with the request queue and it works reliably. However, the problem occurred when I wanted to send a POST request after a GET request and vice versa. I can send multiple requests of the same type until I send a request of a different type - I get a "Can't send bad request" error (request.open = false)

Hi @DavidAntonin

I'm currently have no time to spend on this issue yet.

Can you try by

  1. Using ESP32 core v2.0.1 (not v2.0.2). Some HTTPS was reportedly causing issue in Connection problem via https ESP32S2 #6117

then post your test result here.

khoih-prog commented 2 years ago

More to try and digest

  1. WiFiClientSecure handshake fails after client.stop(). Regression in 2.0.2 #60770

As a workaround for the issue, one can add client.setHandshakeTimeout(30); before every connection attempt.

  1. ESP32 core 2.0.2 does not work (2.0.1 does) #270

A temporary fix that worked for me was to change line 266 in the ssl_client.cpp (in the WiFiClientSecure library) file from:

if((millis()-handshake_start_time)>ssl_client->handshake_timeout)

to:

if((millis()-handshake_start_time)>(ssl_client->handshake_timeout != 0?ssl_client->handshake_timeout:120000))

(So I manually set a timeout if the handshake_timeout is zero.)

Adapt the new example AsyncHTTPSRequest_ESP_Multi of the new AsyncHTTPSRequest_Generic releases v1.4.1

In the current design, each AsyncHTTPSRequest instance can only be use for one address and one type of request (GET, POST, etc,).

It's more complex to completely rewrite the library, than to write the code using multiple instances.

So I don't think I'll spend the time to fix the library in the near future.

Good Luck,

Hi @khoih-prog Thank you four your time and example. I will adot it to my program Have a nice day
