发送POST请求rails

我是Ruby / Rails的新手,我正在尝试创建一个简单的API来保存啤酒模型(名称和酒精百分比)。我用rails gem rails-api实现了API,但是我发送POST请求有问题。由于语法错误(使用邮递员发送请求),我得到400 ERROR。

我不知道我做错了什么。这是我的啤酒控制器:

class BeersController < ApplicationController
  before_action :set_beer, only: [:show, :update, :destroy]

  # GET /beers
  # GET /beers.json
  def index
    @beers = Beer.all

    render json: @beers
  end

  # GET /beers/1
  # GET /beers/1.json
  def show
    render json: @beer
  end

  # POST /beers
  # POST /beers.json
  def create
    @beer = Beer.new(beer_params)

    if @beer.save
      render json: @beer, status: :created, location: @beer
    else
      render json: @beer.errors, status: :unprocessable_entity
    end
  end

  # PATCH/PUT /beers/1
  # PATCH/PUT /beers/1.json
  def update
    @beer = Beer.find(params[:id])

    if @beer.update(beer_params)
      head :no_content
    else
      render json: @beer.errors, status: :unprocessable_entity
    end
  end

  # DELETE /beers/1
  # DELETE /beers/1.json
  def destroy
    @beer.destroy

    head :no_content
  end

  private

    def set_beer
      @beer = Beer.find(params[:id])
    end

    def beer_params
      params.require(:beer).permit(:name, :percent)
    end
end

希望你们能帮助我解决这个问题。提前谢谢!

当我在此请求之后打印日志时,我从heroku日志中获取此信息:

2015-04-06T11:51:40.715123 + 00:00 heroku [router]:at = info method = POST path =“/ beer s”host = drinkapptest.herokuapp.com request_id = e4557a13-1391-4e30-ab8a -069e714b93 d0 fwd =“89.164.165.138”dyno = web.1 connect = 0ms service = 9ms status = 400 bytes = 264

来自邮递员应用的POST应该是这样的结构:

beer[name]       testing
beer[percent]    1

它应该是这样的......

render json: { data: @beer, location: @beer, status: :created }
