warning: 'const char* ArduinoJson::JsonVariantBase<TImpl>::asString() const [with TImpl = ArduinoJson::JsonObjectSubscript<const char*>]' is deprecated

[minida28]

Got below warnings during compilation:

sketch\FSWebServerLib.cpp: In member function 'bool AsyncFSWebServer::loadHTTPAuth()':

sketch\FSWebServerLib.cpp:363:51: warning: 'const char* ArduinoJson::JsonVariantBase<TImpl>::asString() const [with TImpl = ArduinoJson::JsonObjectSubscript<const char*>]' is deprecated (declared at D:\minida28\Dropbox\Arduino\Sketch\libraries\ArduinoJson/include/ArduinoJson/Deserialization/../JsonVariantBase.hpp:36): use as<char*>() instead [-Wdeprecated-declarations]

     _httpAuth.wwwUsername = json["user"].asString();

                                                   ^

sketch\FSWebServerLib.cpp:364:51: warning: 'const char* ArduinoJson::JsonVariantBase<TImpl>::asString() const [with TImpl = ArduinoJson::JsonObjectSubscript<const char*>]' is deprecated (declared at D:\minida28\Dropbox\Arduino\Sketch\libraries\ArduinoJson/include/ArduinoJson/Deserialization/../JsonVariantBase.hpp:36): use as<char*>() instead [-Wdeprecated-declarations]

     _httpAuth.wwwPassword = json["pass"].asString();

As advised by the warning above, I simply change on these lines on FSWebServerLib.cpp file:

    _httpAuth.wwwUsername = json["user"].asString();
    _httpAuth.wwwPassword = json["pass"].asString();

to this

    _httpAuth.wwwUsername = json["user"].as<char*>();
    _httpAuth.wwwPassword = json["pass"].as<char*>();

No more warnings.

I was on:

• Arduino IDE 1.8.1
• FSBrowserNG master
• ArduinoJSON 5.8.3

Maybe not really an issue but I just don't know if there will be side effects to this library by doing the changes above.

Thanks for the great library though!
