Dynamicly add Wifi credential insted of hard coding

[Ramjivan]

Hi folks,

I was to add WiFiManager Library to provide feature of adding WiFi credentials dynamically, Later I found it was using ESP8266Webserver Library and the same lib is being utilized by webthing lib.

Can anybody tell me how can I resolve this issue.

Here's the error I'm encountering

Quick look shows that WiFiManager is using ESP8266WebServer, whereas ESPWebThingAdapter uses ESP8266AsynWebServer. Both define the HTTP methods. It might be possible to combine them (using #define and #ifdef) ... or mod'ing the WiFiManager to use Async might do it. ESPWebThingAdapter should definitely (IMO) use the Async version.

Modifying WiFiManager to use Async does not solves the problem

This seems like an issue with the web server libraries, not directly with this library. Closing.
