h2c

headers 2 curl. Provided a set of HTTP request headers, output the curl command line for generating that set.

$ cat test
HEAD  / HTTP/1.1
Host: curl.haxx.se
User-Agent: moo
Shoesize: 12

$ ./h2c < test
curl --head --http1.1 --header Accept: --user-agent "moo" --header "Shoesize: 12" https://curl.haxx.se/

or a more complicated one:

$ cat test2
PUT /this is me HTTP/2
Host: curl.haxx.se
User-Agent: moo on you all
Shoesize: 12
Cookie: a=12; b=23
Content-Type: application/json
Content-Length: 57

{"I do not speak": "jason"}
{"I do not write": "either"}

$ ./h2c < test2
curl --http2 --header Accept: --user-agent "moo on you all" --header "shoesize: 12" --cookie "a=12; b=23" --header "content-type: application/json" --data-binary "{\"I do not speak\": \"jason\"} {\"I do not write\": \"either\"}" --request PUT "https://curl.haxx.se/this is me"
