How to build a valid HTTP Response. Recv failure: Connection reset by peer
I'm developing an Arduino server that should respond with a message when it receives a POST Request.
If I test my project with a HTTP Client (like insomnia or postman), I get an error:
Error: Failure when receiving data from the peer
I still get a response that I can read but with a final error.
That's my client request:
> POST /SOMETHING/ HTTP/1.1
> Host: [ARDUINO IP]
> User-Agent: insomnia/6.2.0
> Accept: */*
> Content-Length: 0
And this is my Arduino response considered as not valid:
< HTTP/1.1 200 OK
< Connection: close
< [MY MESSAGE]
* Recv failure: Connection reset by peer
* stopped the pause stream!
* Closing connection 2
As you can notice, I just added 2 strings
HTTP/1.1 200 OK
Connection: close
before the real message.
Am I missing something to create a valid response?
Thanks

HTTP requires an empty line after HTTP headers.
First line is status line. Then the header lines. The headers are terminated by an empty line. Then the response body follows. Line terminator for HTTP is rn. Arduino println() function uses rn.
The response with body should contain Content-type and Content-length header. Alternative to Content-lenght is "chunked" Transfer-Encoding.

Thanks, it works. I just don't know why it still doesn't work in insomnia or postman even if it works if I read the request from a browser. Insomnia keeps saying:< HTTP/1.1 200 OK < Content-Type: text/html < Connection: close * Received 9 B chunk * Recv failure: Connection reset by peer * stopped the pause stream!... looks like it receives the response but there's still the "recv failure" error.

you don't send content length, so the client doesn't know where the body ends. it waits for more data and you close the connection. browser tolerates it or has some orientation in the body structure (html tags?)
