Hi! I’m trying implement a HTTP client using erlang library :gen_tcp and the section of code that should recover packet from socket are take too long time to return. My function is: def request(url) do %{host: host, port: port, path: path} = get_information(url) {:ok, ipadress} = :inet.ge…

I believe you need to close the writing side of the socket with :gen_tcp.shutdown(socket, :write) before being able to read the response.

Exactly that, the message in original post is only partial HTTP request as it has no ending, so server waits for the rest until it times out.

This solved my problem. Thanks!

I miss-typed the \n, thank you very much! Didn’t know it has a real purpose on the :gen_tpc, oh well

:gen_tcp.recv() take long time to return

Try with

:ok = :gen_tcp.send(socket, "GET #{path} HTTP/1.1\r\n\r\n")
