branch: masterIn Kemal, a route is an HTTP method paired with a URL-matching pattern. Each route is associated with a block:
get "/" do
.. show something ..
end
post "/" do
.. create something ..
end
put "/" do
.. replace something ..
end
patch "/" do
.. modify something ..
end
delete "/" do
.. annihilate something ..
end Accessing the environment (query params, body, content_type, headers, status_code) is super easy. You can use the environment returned from the block:
# Matches /hello/kemal
get "/hello/:name" do |env|
name = env.params["name"]
"Hello back to #{name}"
end
# Matches /resize?width=200&height=200
get "/resize" do |env|
width = env.params["width"]
height = env.params["height"]
end
# Set the content as application/json and return JSON
get "/user.json" do |env|
kemal = {name: "Kemal", language: "Crystal"}
env.content_type = "application/json"
kemal.to_json
end
# Add headers to your response
get "/headers" do |env|
env.add_header "Accept-Language", "tr"
env.add_header "Authorization", "Token 12345"
endThanks to Manas for their awesome work on Frank.
