can you help me please

What do you need help with ?

The compiler found multiple libraries with the same name and resolved the conflict

et maintenant j'ai cette erreur

Do you have this library installed and, if so, where is it located on your PC ?

no i can't find this library

Which board do you have selected in the IDE ?
Which version of the ESP8266 board files do you have installed ?

StreamDev.h is on my PC in the following folder

C:\Users\Bob2\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.2\cores\esp8266\StreamDev.h

Substitute your Windows Username for mine (Bob2) and look in that folder

it's v3.1.2

i found this "C:\Users\UTILISATEUR\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.2\cores\esp8266\StreamDev.h" and this error now

As I understand it, the error message says that your sketch is using a call to the http.begin() function that is no longer supported, ie

    http.begin(httpurl);

and that it should be replaced by

    http.begin(client, httpurl);

This is not an area that I have much knowledge about, but it is worth a try

10

ok thanks is good

11

Are you saying that your code compiles now ?

How did you solve the problem with StreamDev.h not being found ?

12

in the end it doesn't work either

13

Please post the full sketch that produces that error

14

I believe that you have made other changes to your original code. Did you rename client to Client in this line ?

    WiFiClient client = server.available();

By the way, the sketch compiles for me

}

That is very different from the code that you originally posted. For instance, nowhere in the latest one do you declare a WiFiClient as you do in the original one so this line

        http.begin(client, httpurl);

can never work
