在RSpec请求规范中的每个请求之前设置标头

require 'rspec'
require 'rack/test'

RSpec.describe 'API' do
  include Rack::Test::Methods

  before do
    header 'Content-Type', 'application/json'
    header 'Authorization', 'Bearer token'
  end

  def app
    # 这里是你的应用程序实例
  end

  it 'should return a successful response' do
    get '/api/endpoint'
    expect(last_response.status).to eq(200)
  end

  it 'should return the correct data' do
    get '/api/endpoint'
    expect(JSON.parse(last_response.body)).to eq({ 'key' => 'value' })
  end
end
