[Q] Help port from me-no-dev to this repo - getparam() need different data

[softwarecrash]

hello and thank you for this project,
i switched from the me-no-dev espasyncwebser to this, so i ran into a issue with the getparam

here is the little function, it is for setting different variables over web adress, here a short version

server.on("/set", HTTP_GET, [](AsyncWebServerRequest *request)
            {
    AsyncWebParameter *p = request->getParam(0);
    if (p->name() == "sw1")
    {
      if(p->value().toInt() == 1){
       switch1 = true
      }
      if(p->value().toInt() == 0){
       switch1 = false
      }
   }
    if (p->name() == "sw2")
    {
      if(p->value().toInt() == 1){
       switch2 = true
      }
      if(p->value().toInt() == 0){
       switch2 = false
      }
   }

with
http://<DEVICE_IP>/set?sw1=0

so i get the error

src\main.cpp:512:49: error: call of overloaded 'getParam(int)' is ambiguous
  512 |       AsyncWebParameter *p = request->getParam(0);
      |                                                 ^

how can i solve this?

thank you

thank you, but have you a hint how to solve it? i doenst understand the changes complete

so on the readme at https://github.com/mathieucarbou/ESPAsyncWebServer?tab=readme-ov-file#get-post-and-file-parameters
it looks like

if(request->hasParam("download"))
  AsyncWebParameter* p = request->getParam("download");

but when i grab this for test i got a

src\main.cpp:515:43: error: invalid conversion from 'const AsyncWebParameter*' to 'AsyncWebParameter*' [-fpermissive]
  515 |   AsyncWebParameter* p = request->getParam("download");
      |                          ~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
      |                                           |
      |                                           const AsyncWebParameter*

If you didn't solve the issue, I am pretty sure the compiler is telling you to replace:

AsyncWebParameter* p = request->getParam("download");

to be:

const AsyncWebParameter* p = request->getParam("download");

Which means just adding a const to the definition.
