据我所知，在控制器规格内不再可以发送原始POST数据。但是，可以在请求规范中轻松完成此操作：
describe "Example", :type => :request do params = { token: 0 } post "/user/reset_password", params.to_json, { 'CONTENT_TYPE' => 'application/json', 'ACCEPT' => 'application/json' } #=> params contains { "controller" => "user", "action" => "reset_password", "token" => 0 }end
