Display txt file on async Webserver using esp8266

[kaan9700]

Hey,
I have several txt files on my SD card that I would like to output to my async webserver. I use the ESP8266 for this.
I have tried it with the following call. However, an error is then displayed.
It also says that two SD.h libraries were found:

Library/Arduino15/packages/esp8266/hardware/esp8266/3.0.2/libraries/SD

/Applications/Arduino.app/Contents/Java/libraries/SD

the latter is not used.

The error I get is the following:
no matching function for call to 'AsyncWebServerRequest::send(SDClass&, const char [12], const char [10])'

how can I solve this problem?

  server.on("/getdata", HTTP_GET, [](AsyncWebServerRequest *request){
    request->send(SD, "/subj1_1.txt", "text/plain");
  });

Basically Version 2.0 is a beta version and still need some update Try doing the same thing in version 1.8.57.0 and then check does the same error is still occurring

Basically Version 2.0 is a beta version and still need some update Try doing the same thing in version 1.8.57.0

what the heck is version 1.8.57?

Is this a more stable "release-candidate" than the actual Arduino 2.0 beta RC
I haven't tested Arduino 2.0 but as it is a beta I expected still a lot of trouble trying to using it.

Be the change you want to see in the world

on both versions I have got the same error

[StefanL38]

[kaan9700]

Also the same

If you get a compiler-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to pos…

Ya U r correct but there are currently a lot of minor bug so if anyone facing an issue we should tell about that error in the software

[StefanL38]

As long as you are as unspecific as "tell about that error in the software" this does not help at all

which error

• using the wrong SD library?
• you using a deprecated library?
• you; having configured your libraries wrong?

in which "software"

• The Arduino IDE?
  -- if yes which version?

• SD-library itself?
  -- if yes which version are you using?

Be the change you want to see in the world
