Question

我进行了以下测试：

require 'rails_helper'

  RSpec.describe 'User management', :type => :request do
    before do
      @expected_number_of_users = 3
    end

    context 'an authenticated user with admin privileges' do
      before do
        # This username/password combo is in my fixtures
        @headers = login_user 'scottj', '123456'
      end

      context 'when at least a username, name, role, and email address are passed as inputs' do
        before do
          @new_user_details = {
            :username => 'stitch',
            :name => 'Stitch',
            :role => :admin,
            :email => 'stitch@disney.com'
          }
        end

        it 'should create a new user' do
          post users_path, headers: @headers, params: @new_user_details
          expect(response).to have_http_status(:ok)

          expect(json.username).to eq('stitch')
          expect(json.name).to eq('Stitch')
          expect(json.role).to eq(:admin.to_s)
          expect(json.email).to eq('stitch@disney.com')
          expect(json.password).to_not be_nil
        end
      end
    end
  end

带有以下login_support.rb文件：

module LoginSupport
  def json_api_headers
    {
      "Content-Type": 'application/json',
      "Accept": 'application/json'
    }
  end

  def login_user(username, password)
    combined_login_password = username + ":" + password
    encoded_username_password = Base64.encode64(combined_login_password)
    headers = {
      'X-Api-Key': Client.find_by_id(1234).api_key,
      'Authorization': 'Basic ' + encoded_username_password
    }.merge(json_api_headers)

    post '/login', headers: headers

    user = JSON.parse(response.body, object_class: OpenStruct)

    {
      'Authorization': 'Bearer ' + user.auth_token
    }
  end
end

此测试按预期通过，但是当我将login_user的返回类型更改为（即，更改该函数的最后三行）时：

{
  'Authorization': 'Bearer ' + user.auth_token
}.merge(json_api_headers)

现在，当我运行测试时，出现错误：

ActionDispatch::ParamsParser::ParseError: 765: unexpected token at 'username=stitch&name=Stitch&role=admin&email=jaywir3%40gmail.com'

在我看来，标头的更正确版本是这样的，因为我的API都希望以JSON形式接收POST请求的正文，并返回JSON，标头到位。在我看来，指定了这些标头的POST请求正试图将请求的主体作为查询参数传递。

我在做错什么吗？测试时，我应该只将Accept和Content-Type标头保留在请求之外吗？

为什么在此测试中，接受：application / json和内容类型：application / json导致问题？
