axios POST請求（javascript）和Sinatra / Base API（紅寶石）的問題

Question

使用javascript庫axios嘗試向Ruby Sinatra / Base API發出POST請求時，我一直遇到問題

我在下面的Sinatra API中有一個示例POST路由，axios不斷給我帶來一般錯誤

# Running on http://localhost:9292

class Endpoints < Sinatra::Base
  register Sinatra::MultiRoute

  before do
    headers 'Access-Control-Allow-Origin' => 'http://localhost:8080',
      'Access-Control-Allow-Methods' => ['OPTIONS', 'GET', 'POST'],
      'Access-Control-Allow-Headers' => ['Content-Type']
  end

  options '*' do
    headers 'Access-Control-Allow-Origin' => 'http://localhost:8080',
      'Access-Control-Allow-Methods' => ['OPTIONS', 'GET', 'POST'],
      'Access-Control-Allow-Headers' => ['Content-Type']
  end

  route :post, :options, '/create' do
    # does something with params and return a JSON object
  end 
end

使用axios庫的Java代碼：

// Running on http://localhost:8080

axios.post('http://localhost:9292/create', {
  some_val: 'some value'
})
.then(res => {
  console.log(res)
})
.catch(err => {
  console.log(err)
})

我在控制台中不斷收到通用javascript錯誤

POST http://localhost:9292/create 403 (Forbidden)     bundle.js:20263
Error: Request failed with status code 403
  at createError (bundle.js:12159)
  at settle (bundle.js:19627)
  at XMLHttpRequest.handleLoad (bundle.js:11996)

我的服務器端終端沒有給我任何更好的工作方式，它說選項帶有200狀態代碼，但是對於導致403錯誤的原因我卻一無所知...沒有參數使它成功進入我的路線...

::1 - - [08/May/2017:12:49:35 -0700] "OPTIONS /create HTTP/1.1" 200 - 0.0030
::1 - - [08/May/2017:12:49:35 -0700] "POST /create HTTP/1.1" 403 30 0.0076

好，謝謝您，它可以通過以下解決方法為我工作：

before do
    if request.request_method == 'POST'
      body_parameters = request.body.read
      begin
        data= params.merge!(JSON.parse(body_parameters))
        @can_parse = true
      rescue
        puts "LOG: cant parse params" #TODO add real logger
        @can_parse = false
      end
    end
