如何在Ruby中存根请求/响应

require 'webmock/rspec'

describe 'MyClass' do
  before do
    # 存根GET请求
    stub_request(:get, 'http://example.com/api/resource')
      .to_return(status: 200, body: 'Response body', headers: {})
  end

  it 'should make a GET request' do
    response = Net::HTTP.get(URI('http://example.com/api/resource'))
    expect(response).to eq('Response body')
  end
end

require 'vcr'

VCR.configure do |config|
  config.cassette_library_dir = 'fixtures/vcr_cassettes'
  config.hook_into :webmock
end

describe 'MyClass' do
  it 'should make a GET request' do
    VCR.use_cassette('my_cassette') do
      response = Net::HTTP.get(URI('http://example.com/api/resource'))
      expect(response).to eq('Response body')
    end
  end
end
