How to do HTTP GET with netcat?

Question

I am trying to use netcat to submit an HTTP GET request. But it gives me the 505 error.

Does anybody know what is wrong with my use of netcat?
Thanks.

Answer 1

Here is a more readable solution.

$ sed 's/$/\r/g' <<EOF | netcat -v httpbin.org 80
GET /get HTTP/1.1
Host:httpbin.org

EOF

Answer 2

You must use CRLF line endings, and you must include a Host header.

~$ printf 'GET /get HTTP/1.1\r\nHost:httpbin.org\r\n\r\n' | nc -v httpbin.org 80 
HTTP/1.1 200 OK
