我们可以写
get '/foo' do
...
end
和
post '/foo' do
...
end
哪个好。但是我可以在一个路由中组合多个HTTP动词吗?
答案 0 :(得分:33)
这可以通过作为sinatra-contrib的一部分的multi-route
extension来实现:
require 'sinatra'
require "sinatra/multi_route"
route :get, :post, '/foo' do
# "GET" or "POST"
p request.env["REQUEST_METHOD"]
end
# Or for module-style applications
class MyApp < Sinatra::Base
register Sinatra::MultiRoute
route :get, :post, '/foo' do
# ...
end
end
但请注意,您可以通过以下方式自行完成此操作:
foo = lambda do
# Your route here
end
get '/foo', &foo
post '/foo', &foo
或者更优雅地作为元方法:
def self.get_or_post(url,&block)
get(url,&block)
post(url,&block)
end
get_or_post '/foo' do
# ...
end

FWIW,我只是手动完成,没有辅助方法或扩展名:
%i(get post).each do |method|
send method, '/foo' do
...
end
end
虽然如果你做得很多,那么将它抽象出来当然是有意义的。

Phrogz有一个很好的答案,但如果lambdas或包括sinatra-contrib不适合你,那么这个元方法将达到与sinatra-contrib相同的结果:
# Provides a way to handle multiple HTTP verbs with a single block
#
# @example
# route :get, :post, '/something' do
# # Handle your route here
# end
def self.route(*methods, path, &block)
methods.each do |method|
method.to_sym
self.send method, path, &block
end
end
如果您对能够向self
发送任意方法有点谨慎,那么您可以通过在数组中设置允许方法的白名单来保护自己,然后检查符号在阵列。
# Provides a way to handle multiple HTTP verbs with a single block
#
# @example
# route :get, :post, '/something' do
# # Handle your route here
# end
def self.route(*methods, path, &block)
allowed_methods = [:get, :post, :delete, :patch, :put, :head, :options]
methods.each do |method|
method.to_sym
self.send(method, path, &block) if allowed_methods.include? method
end
end

这是一个服务不可用的服务器,我设法获得单行:)
require 'sinatra';set port: ARGV[0]||80;%w.get post put patch options delete..map{|v|send(v,'*'){503}}
我实际上用它来测试面对503s的某些客户端代码的行为。
