but don't know how to fix.
Q1: how is the best way to avoid this (i am using a locked-variable at the moment).
Q2: since its async somehow, is there task scheduling and running on different cores@esp32 involved? Best way to exchange "data"/share aviables between "global code" and webserver(callbacks?
Hope im not mixing things too much - and sri for some rookie questening stuff :) Tnx for your support. M.
Can it handle multipart form? I browsed the readme, but the only thing I could find was multipart() that returns true/false. I want to know whether it can read values from a multipart POST. I confirmed that my POST code works correctly by posting it to https://httpbin.org/post; it returned
{
"args": {},
"data": "",
"files": {},
"form": {
"cat": "\u0001\u0002\u0000\u0003\u0004",
"dog": "hello"
},
"headers": {
"Content-Length": "265",
"Content-Type": "multipart/form-data; boundary=\"8a9f2dc0-11a8-451a-9d5e-376624de7af7\"",
"Host": "httpbin.org", .....So, I want to get that "dog" and "cat" in my ESP. But when I listed all arguments using the readme code:
//List all parameters (Compatibility)
int args = request->args();
for (int i = 0; i < args; i++)
{
Serial.printf("ARG[%s]: %s\n", request->argName(i).c_str(), request->arg(i).c_str());
}what I got was:
ARG[o]:
ARG[a]: ␁␂So, how can I get the string "hello" for the "dog" argument, and { 0x01, 0x02, 0x00, 0x03, 0x04 } for the "cat" argument? Is it supported? Any example?

How can I alter content based on a GET requests accept header?
I have a piece of code that looks like this:
server.on("/", HTTP_GET, [](AsyncWebServerRequest * request) {
request->send(SPIFFS, "/index.html", String(), false);
});which works as designed. However I need to send back different data, depending on the Accept header. Something like this:
server.on("/", HTTP_GET, [](AsyncWebServerRequest * request) {
if (request->contentType() == "application/json") {
request->send(200, "text/json", String(publishData));
} else {
request->send(SPIFFS, "/index.html", String(), false);
}});Doesn't seem to work. What do I miss?
Any idea to fix this?
Hi!
I just couldn't find any working examples for TLS so I made an example sketch for TLS WebServer using this library.
Check it out here: https://gitlab.com/artonworkstm/asyncwebservertls
Also want to fasten up a bit the request process by caching sessions so there is no need to redo the whole handshake at every request.
Do you guys know how may I achieve that?
I found it in the ESP8266WiFi library that you can use there (tho I couldn't make it work).
The Session class is here at line 139: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/src/BearSSLHelpers.h

I would like to serve following files as gzipped with the severStatic-method. Is this possible?
for the files.
Content-Type: application/javascript for jQuery.min
server.on("/", HTTP_GET, [](AsyncWebServerRequest *request)
{
request->send_P(200, "text/html", HTMLhead);
request->send_P(200, "text/html", HTMLmain);
request->send_P(200, "text/html", HTMLfoot);
});
server.on("/", HTTP_GET, [](AsyncWebServerRequest *request)
{
AsyncResponseStream *response = request->beginResponseStream("text/html");
response->printf_P(HTMLhead);
response->printf_P(HTMLMain);
response->printf_P(HTMLfoot);
request->send(response);
});
Hi all. Fairly new and very sorry if answered as I've looked but I'm trying to use AsyncWebServer with SdFat and 128 GB exFAT SDHC. I'm having issues with the following lines in my code since I'm not using SD.h
request->send(SD, "/index.html", "text/html");
});
server.serveStatic("/", SD, "/");
I've tried changing SD to sd, and file objects without success. Also tried FS and fs with no luck. I'm fairly new and jsut not sure what filesystem to send from SdFat for request->send
Do you know how I can concat all the chunks (3 in my case) in a String or in a JSON?
Thank you in advanced
@me-no-dev Thanks for your great lib 😊 I'm trying to migrate from "Stock" Webserver in arduino to ESPAsyncWebServer on an ESP32 project right now, as I need to use WebSockets for some functionality.
Unfortunately I cannot get the lib to build with ESP-IDF 4.4. It already fails when I try to include it.
Besides the CMakeLists format is still the "old" IDF style, I don't see any obvious issue.
I added the lib as a component, added AsyncTCP as a component and added arduino-esp as a component (within components/arduino).
Is there any point I'm missing?

hi all
I made a couple of header file for different prepherals + header file for my asyncserver & asyncwebsocket
my_wifi.h
AsyncWebServer server(80);
AsyncWebSocket WS("/ws");in other header file I have sensor to measure sumeting and send through websocket
my_sensor.h
WS.textAll(my_data);but it can not see my WS instance error: 'WS' was not declared in this scope
does anyone know how can I pass my WS instance to other header files
Hi guys, i still have a problem - no idea what to do, heres again my question: I am reading an value continously in my main/loop-code and writing it in a global variabal. in my server.on callback/handler function i am reading this value and returning it to the clients browser. for sure its crashing when i write it the same time.

why not with websocket?
Short problem description: There is a project thats all done in javascript. It uses a raspberry as socket.io server to do hardware things that a js client on a pc directs via socket.io. I cant really change the PC part but i want to replace the raspberry with esp8266 to scale prizes and make it "easier" to build.
but i cant find any resources for a socket.io server. Only clients everywhere.
WS.text(WSclinet,data); however after a while _messageQueue.length() exceeded of maximum size and throw ERROR: Too many messages queued , does anyone know how to solve it
clearQ after each transmitting void AsyncWebSocket::clearQ(uint32_t id){
AsyncWebSocketClient * c = client(id);
if(c)
c->QueuFree();
}
.......
void AsyncWebSocketClient::QueuFree(){
_messageQueue.free();
}
