如何从Sinatra中转储HTTP请求？
有没有办法以应用程序接收数据的确切方式将所有传入请求转储到Sinatra应用程序？ 也许是某种Rack中间件？
当我想调试’事物’时，我用-D和-V标志运行：
$ thin start -p 3000 -R config.ru -D -V -D, --debug Set debbuging on -V, --trace Set tracing on (log raw request/response)
如果您尝试从请求获取原始输出，请使用请求方法，如：
# app running on http://example.com/example get '/foo' do request.body # request body sent by the client (see below) request.scheme # "http" request.script_name # "/example" request.path_info # "/foo" request.port # 80 request.request_method # "GET" request.query_string # "" request.content_length # length of request.body request.media_type # media type of request.body request.host # "example.com" request.get? # true (similar methods for other verbs) request.form_data? # false request["SOME_HEADER"] # value of SOME_HEADER header request.referer # the referer of the client or '/' request.user_agent # user agent (used by :agent condition) request.cookies # hash of browser cookies request.xhr? # is this an ajax request? request.url # "http://example.com/example/foo" request.path # "/example/foo" request.ip # client IP address request.secure? # false request.env # raw env hash handed in by Rack end

也许这不是你要问的，但我到了这里寻找一种方法来查看Sinatra中的所有HTTP请求头（实际上不必枚举它们，来调试代理请求）。 我发现这非常有用：
get "/my_route" do puts "#{ request.env }" end
或者，以可读的json格式返回响应中的blob：
require 'json' get "/my_route" do content_type :text return JSON.pretty_generate(request.env) end
瞧，所有请求细节：
