gem“rack cors”不工作,角度客户端请求rails api抛出cors错误

我正在努力让gem“rack cors”在当地工作。我用gem'devieve_token_auth'安装了裸rails,用'angular token'安装了angular 7客户端。但安格尔的每一个要求都是投球失误。我已经按照文档配置了rails和rack cors,但它不起作用。这是我的配置 application.rb

config.middleware.insert_before 0, Rack::Cors do
      allow do
        origins '*'
        resource '*',
          headers: :any,
          expose: ['access-token', 'expiry', 'token-type', 'uid', 'client'],
          methods: [:get, :post, :options, :delete, :put]
      end
    end

如果我列出中间商使用 rails middleware , Rack::Cors 排在第二位 use Webpacker::DevServerProxy 但每个请求都会引发以下错误。

Processing by DeviseTokenAuth::SessionsController#create as HTML
