我正在测试一个JSON请求到我们的API，它将用JSON响应。看起来JSON中的所有整数都被转换为字符串，因为我们将它们发布到控制器consideraction。

控制器

def consider
    binding.pry # binding no# 2 used to check the params after post from test.
    if ParametersValidator.is_valid?(params)
      application_handler = ApplicationHandler.new(request_interactor)
      render json: application_handler.result
    else
      render json: ParametersValidator.failed_params(params).to_json
    end
  end

字符串
ParamaterValidator验证传入数据的结构和类型。

测试

render_views
let(:json) { JSON.parse(response.body) }
..
..

it 'returns the result in the correct format for the AUTOMATIC APPROVE decision' do
  automatic_approve_params = relative_json_file(relative_file('automatic_approve_params'))
  expected_approve_params = {
    "status" => "accepted",
    "automated" => true,
    "rate" => 6,
    "amount" => 30000,
    "term" => 10,
    "pre_approved_amount" => 2500,
    "comments" => ""
  }
  @request.headers['HTTP_X_AUTH_SIG'] = Rails.application.secrets['authorization']['token']
  request.env["HTTP_ACCEPT"] = 'application/json'

  binding.pry  # binding no# 1 to inspect the params before post

  post :consider, automatic_approve_params, format: :json
  expect(json).to eq(expected_approve_params)
end

测试日志显示请求是

Processing by Api::V1::CreditApplicationsController#consider as JSON

型
在post操作之前检查请求，你会看到参数是正常的，然后在控制器中，在我运行任何东西之前，我检查参数，它们都是字符串。
使用postman来测试API与JSON的工作原理与预期一样，但似乎rspec在发布到consider操作时会将所有参数转换为字符串。我读过几十篇文章，声称通过将format: :json添加到帖子操作中可以解决这个问题，但是我没有这样的运气。
我显然做错了什么，但我已经尝试了几乎所有我知道的。
