如何建立对Rails POST方法的邮递员请求 [英] How to build postman request for Rails POST method

问题描述

无论我如何格式化请求的原始部分，我都无法避免下面的解析错误。

No matter how I format the raw portion of this request, I cannot avoid the parsing error below.

我有一个Rails API，其create方法可以传递规范，以说明控制器消息是正确的：

I have a Rails API with a create method that passes the spec, to illustrate that the controller message is sound:

describe "POST power_up" do

    let!(:client) { FactoryGirl.create :client, name: "joe", auth_token: "asdfasdfasdfasdfasdfasdf" }

    it "should create and save a new Power Up" do

      expect { post :create, format: :json, power_up: FactoryGirl.attributes_for(:power_up) }.to change(V1::PowerUp, :count).by(1)
    end

  end

我正在使用Postman尝试对其进行发布。不管我尝试什么，都会遇到错误：

I'm using Postman to try to POST to it. No matter what I try I'm getting the error:

Started POST "/v1/power_ups.json" for 127.0.0.1 at 2014-08-30 18:05:29 -0400
Error occurred while parsing request parameters.
Contents:

{
  'name': 'foo',
  'description': 'bar'
}


ActionDispatch::ParamsParser::ParseError (795: unexpected token at '{
  'name': 'foo',
  'description': 'bar'
}

邮递员请求设置：

我也尝试过：

{
  'power_up': {
    'name': 'foo',
    'description': 'bar'
   }
}

创建方法和强大的代码 power_ups_controller.rb 中的参数声明：

Code from create method and strong parameters declaration in power_ups_controller.rb:

def create
    @power_up = PowerUp.new(power_up_params)

  if @power_up.save!
    redirect_to @power_up
  end
end

private

  def power_up_params
    params.require(:power_up).permit(:name, :description)
  end

推荐答案

很抱歉，回答这个问题为时已晚，但可能会对其他人有所帮助。

Sorry bit too late to answer this but might help someone else.

您需要做的就是在请求标头（在邮递员或任何客户中）中添加-

All you need to do is - in your request header (in postman or whatever client) add

Content-Type ='application / json'

，也可以尝试使用curl（源）：

Alternatively, you can also try it with curl (source):

curl -X POST -H Content-Type：application / json -d '{ power_up：{
name： foo，
description： bar
}
}'127.0.01：3000 / v1 / power_ups .json
