nRF9160-DK HTTP POST REQUEST

[Gioele]

Hi!
We are trying to send an HTTP request to our AWS Web Server.
The problem that we are figuring out now is that we don't know the way to add a body to our request.
We based our code on the Connection Example provided by Nordic (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/https_client/README.html), but It doesn't work. Sometimes we have no response and sometimes we obtain a "BAD REQUEST" response from the server.

#define BODY  "{ \"jsonrpc\": \"2.0\", \"method\": \"eth_chainId\" }"



#define HTTP_HEAD "POST HTTP/1.1\r\n"\
		"Host: "HTTPS_HOSTNAME"\r\n"\
		"Connection: close\r\n"\
	    "Content-type: application/json\r\n"\
		""BODY"\r\n\r\n"

We need your help! Thank you!

This is the URL #define HTTPS_HOSTNAME "ec2-184-73-45-204.compute-1.amazonaws.com"

If I make the same request on PostMan it runs!

No, that is the hostname. You also need the path to the resource you want to get/modify.

Try add a '/' between the request method and the protocol version (separated by spaces), if you want  to modify the root object.

We tried to add a "/" but we have the same error. This is the exact request that we make on Postman.

Is the server running?

I am trying to send the request myself, but the connection to the server times out.

Probably the server wasn't running but now everything is fine. We understood that the solution is the "/" that you mentioned plus the correct "content-length" of the body. Thank you!
