发送数据

Question

我想测试我的葡萄:: API和集成测试中specs/requests

我只使用RSpec的，没有水豚或任何东西。

我只是想在我整合规范后的数据，我不断收到undefined method 'to_sym'

这是我迄今为止

before do 
     post "/v1/users", { :user => { 
     :username => "testuser", :password => "pass", :password_confirmation => "pass" } 
     }.to_xml, @api_key.merge({'HTTP_CONTENT_TYPE' => 'application/xml'}) 
    end 

@api_key merely持有HTTP_AUTHORIZATION头

上午什么我在这里做错了吗？更新葡萄的最新版本，以解决这个问题（ -
