Webmock stub request with any body and header

问题:

How to use Webmock to stub request with any body and header? I tried to use regex

WebMock.stub_request(:post, 'api.quickblox.com/').with(:body => /.*?/, :headers => /.*?/).to_return(:status => 201, :body => "", :headers => {})

in rspec but it doesn't work, it has

NoMethodError:
   undefined method `map' for /.*?/:Regexp

回答1:

Check out the Webmock docs on headers. You need to provide it a hash with further details on what you are matching.

回答2:

You should be able to just use

WebMock.stub_request(:post, 'api.quickblox.com/')
  .to_return(status: 201, body: 'whatever', headers: { some_kind_of: 'header' })

If you don't specify the body or headers on the stub itself, it will allow anything for the body or headers. This does not apply to query parameters.

For example, this sample project's test passes:

bundle exec rspec output:

Test
  does a thing

class Test
  def self.do_a_thing
    JSON.parse(Faraday.get('http://www.example.com') do |request|
      request.headers['Something'] = 'anything'
      request.body = 'bla bla bla'
    end.body)
  end
end

spec/test_spec.rb

require_relative '../lib/test.rb'
require 'webmock/rspec'

describe Test do
  WebMock.stub_request(:get, 'http://www.example.com')
    .to_return(body: '{ "this": "is a test" }')

  it 'does a thing' do
    expect(described_class.do_a_thing).to include({ 'this' => 'is a test' })
  end
end
