用于 Swagger 测试的带有 Apivore 的 Rails RSpec

我正在尝试设置 Apivore Gem 来测试我的 API 上的 Swagger 文档。但是我很难理解如何将内容作为 JSON 发送到正文中。

Swagger 文档

      responses:
        200:
          description: 'User logged in successfully'
          schema:
            type: object
            properties:
              access_token:
                type: string
                description: 'Authorization access token'
                example: '0ee0e77afbdd6fcaa0920a0416d5043aee9a21ca75920cda7d2b1be0d9f40885'
              token_type: 
                type: string
                description: 'Authorization token type'
                example: 'Bearer'
              expires_in:
                type: integer
                description: 'Timestamp expiration time'
                example: 3600
              refresh_token:
                type: string
                description: 'Refresh authorization token'
                example: 'ed1307dde23acbb440d6f31520f7d3c8de099e72b04eb1542008ca139fca6364'
              created_at:
                type: integer
                description: 'Timestamp created at time'
                example: 1519312812

带有 Apiore 测试的 RSpec

require 'rails_helper'

RSpec.describe 'the API', type: :apivore, order: :defined, focus: true do
  subject { Apivore::SwaggerChecker.instance_for('/docs/swagger.json') }

  context 'has valid paths' do
    Fabricate(:user, email: '[email protected]', password: 'abc123', password_confirmation: 'abc123')

    let(:credentials) { { 'grant_type' => 'password', 'username' => '[email protected]', 'password' => 'abc123' } }

    let(:params) do
      {
        '_headers' => { 'accept' => 'application/json', 'content-type' => 'application/json' },
        '_data' => credentials.to_json
      }
    end

    specify do
      expect(subject).to validate(
        :post, '/oauth/token', 200, params
      )
    end
  end

  context 'and' do
    it 'tests all documented routes' do
      expect(subject).to validate_all_paths
    end
  end
end

错误信息

Failures:

  1) the API has valid paths should validate that post /oauth/token returns 200
     Failure/Error: expect(subject).to validate(
       Path /oauth/token did not respond with expected status code. Expected 200 got 401
       Response body:
        {
         "error": "invalid_grant",
         "error_description": "The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."
       }
     # ./spec/requests/api_swagger_spec.rb:19:in `block (3 levels) in <top (required)>'

但是我尝试使用 Postman 获取令牌并工作。如果凭据内容或凭据密钥错误，则会出现此错误消息。
