Ruby:接收并打印JSON对象

don*_*ald 2 javascript ruby sinatra node.js ruby-on-rails-3

我想使用Ruby接收JSON对象.我写过:

require 'sinatra'
require 'json'

post '/' do
  push = JSON.parse(params[:payload])
  "I got some JSON: #{push.inspect}"
end

而且我发送:

var options = {
                  host: 'localhost',
                  port: 4567,
                  path: '/',
                  method: 'POST'
                };

var myFirstJSON = { "payload" : { "headers" : 
                                            [{ "from" : from,
                                                "to"  : to,
                                                "subject" : subject }],
                                "body"    : 
                                            [{ "primeira_parte" : primeira_parte,
                                                "segunda_parte" : segunda_parte,
                                                "terceira_parte": terceira_parte }]
                                }};
            req.write(JSON.stringify(myFirstJSON));

但是,我收到此错误:

你想要的是这样的路线:

post '/' do
  push = JSON.parse(request.body.read)
  "I got JSON: #{push.inspect}"
end

您不是对数据进行编码的表单,因此它不会在参数中设置.
