How does Sinatra's `put` work?

Question

get in Sinatra displays whatever you want when you type the path into the URL. I don't put. How do you call put?

I am trying to run

put '/:name' do |name|
  puts "hello " + name
end

How do I actually call this? I type into my browser:

http://localhost:4567/examplename\

but when I read it in my terminal (cmd prompt), it tries to access it as get. What am I missing regarding how put works?

Answer 1

The put method corresponds with an HTTP PUT request. If you're making a GET, which is what the browser does by default, you should change that to:

get '/:name' do |name|
  # ...
end

If you're talking about "how do I write to the browser" then you need this:

get '/:name' do |name|
  "hello #{name}"
end

Don't write things to STDOUT with puts, just return the content you want to be sent. That's how Sinatra works.

If you want to make a PUT request you need to tell your tool to use that method. For example, with curl -X PUT.

You can use Advanced REST Client Chrome Extension. Enter your URL in the URL field, select PUT for the http verb and click on Send button. You will the result in the Response text area.
