I’m integrating allure reports with my API test project using Rspec.
I wanted to attach request and response details to the report after each testcase.

• The following is my response_parser to get needed request and response details.

module ResponseParser
  extend self

  def get_request_body(response)
    request_body = response[:request].body
    puts "#{request_body.class}"
    request_body
  end

  def get_request_headers(response)
    headers = []
    response[:request].each_header do |header, value|
      headers << "#{header}: #{value}"
    end
    puts "#{headers.class}"
    headers
  end

  def get_request_method(response)
    request_method = response[:request].method
    puts "#{request_method.class}"
    request_method
  end

  def get_request_uri(response)
    request_uri = response[:request].uri
    puts "#{request_uri.class}"
    request_uri
  end

  def get_response_body(response)
    response_body = JSON.parse(response[:response].body)
    puts "#{response_body.class}"
    response_body
  end

  def get_response_headers(response)
    headers = []
    response[:response].each_header do |header, value|
      headers << "#{header}: #{value}"
    end
    puts "#{headers.class}"
    headers
  end

  def get_response_status(response)
    {
      code: response[:response].code.to_i,
      message: response[:response].message
    }
  end
end

and I created an allure_helper to any customizations to the report

# spec/allure_helper.rb

require "allure-rspec"
require_relative '../lib/response_parser'

module AllureHelper
  extend self

  def attach_request_details_to_report(response)
    Allure.add_attachment(
      name: 'request method',
      source: ResponseParser.get_request_method(response),
      type: Allure::ContentType::TXT,
      test_case: true
    )

    Allure.add_attachment(
      name: 'request uri',
      source: ResponseParser.get_request_uri(response),
      type: Allure::ContentType::TXT,
      test_case: true
    )

    Allure.add_attachment(
      name: 'request headers',
      source: ResponseParser.get_request_headers(response).join("n"),
      type: Allure::ContentType::TXT,
      test_case: true
    )

    Allure.add_attachment(
      name: 'request body',
      source: ResponseParser.get_request_body(response).to_json,
      type: Allure::ContentType::JSON,
      test_case: true
    )

    Allure.add_attachment(
      name: 'response status',
      source: ResponseParser.get_response_status(response).to_json,
      type: Allure::ContentType::JSON,
      test_case: true
    )

    Allure.add_attachment(
      name: 'response headers',
      source: ResponseParser.get_response_headers(response).join("n"),
      type: Allure::ContentType::TXT,
      test_case: true
    )

    Allure.add_attachment(
      name: 'response body',
      source: ResponseParser.get_response_body(response).to_json,
      type: Allure::ContentType::JSON,
      test_case: true
    )

    rescue StandardError => e
      puts "Failed to add allure attachment: #{e.message}"
      puts e.backtrace
      example.execution_result.exception = e
  end
end

And the below in my spec_helper where I call the function to attach details to report in the after(:each) hook.

require "rspec"
require "allure-rspec"
require "pathname"

require_relative '../spec/allure_helper'

RSpec.configure do |config|
  config.add_formatter AllureRspecFormatter

  AllureRspec.configure do |c|
    c.results_directory = 'reports/allure-results'
    c.clean_results_directory = true
    c.logger = Logger.new($stdout, Logger::DEBUG)
    c.logging_level = Logger::INFO
  end

  config.after(:each) do |example|
    if @response
      example.metadata[:response] = @response
      AllureHelper.attach_request_details_to_report(@response)
    end
  end

  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

  config.shared_context_metadata_behavior = :apply_to_host_groups
end

when I run tests, I keep getting this error
ERROR -- : Can't add attachment, no test, step or fixture is running
