After ages, finally there is a crystal clear video explaining how to do this. Now I will be able to get my esp32 out of the box again.

Thank you for this, it’s given me a more of a understanding of how and what happens, but wow you’re quick with copy and paste then going to the next step. I’m thankful for the pause and play on the vid lol.

Hey, I'm working on a project that needs to get data from my page on my website. But I came across a problem. When I do the GET command on my page I get this:

Statuscode: 200
<!DOCTYPE html>
<html lang="pt-br">
<head>
</head>
<body>
Array
(
[0] => stdClass Object
(
[AutoIncrement] => 1
[Nome Aparelho] => LED
[Status] => 0
)

)
</body>
</html>

This is when I output the page info:
0.00

0
Could you help me please?

Good video, but what about JSON that's more than 1 dimensional?

andrewmcallister

Great video. Can you also show how it works if I have more than one dataset in JSON file?

franklarsen

i am trying to use this example with my url but getting the response as 200 only. I am not getting json data after that.

Hi great video! can you explain how to add headers to the GET request?

EpsRae

Interesting library there... I'm wondering how it deals with arrays. Will take a look.

WistrelChianti

What if status code is 404? That's greater than 0 but is a resulting error
