Can't make GET request work on TLS/SSL connection
Posted: Wed Feb 15, 2017 1:05 pmAll,
So I'm trying to establish a TLS/SSL connection to a server and then making a GET request with a required Auth header.
first attempt at using WiFiClientSecure and first attempt at using ESP8266HTTPClient.
I think I am getting a good TLS connection but the GET request is failing and I get a HTTP response 400,
"400 Bad Request
The server cannot or will not process the request due to an apparent client error"
I need to send the "X-Amt-Auth" header with the long key to show really, I'm allowed to get this data.
could not find an example of using ESP8266HTTPClient to send a GET request with a header. Any suggestions on what I'm doing wrong here?
