Definitions

GET = "GET"

The GET method requests a representation of the specified resource. Requests using GET should only retrieve data.

HEAD = "HEAD"

The HEAD method asks for a response identical to a GET request, but without the response body.

POST = "POST"

The POST method submits an entity to the specified resource, often causing a change in state or side effects on the server.

PUT = "PUT"

The PUT method replaces all current representations of the target resource with the request payload.

DELETE = "DELETE"

The DELETE method deletes the specified resource.

CONNECT = "CONNECT"

The CONNECT method establishes a tunnel to the server identified by the target resource.

OPTIONS = "OPTIONS"

The OPTIONS method describes the communication options for the target resource.

TRACE = "TRACE"

The TRACE method performs a message loop-back test along the path to the target resource.

PATCH = "PATCH"

The PATCH method applies partial modifications to a resource.

def self.each

Enumerate all HTTP methods.

Signature

parameter　value　String

The value of the method, e.g. "GET".

Implementation

 
def self.each

	constants.each do |name|
		yield name.downcase, const_get(name)
	end
end
