小编Eli*_* K.的帖子

我在 gemfile 中有它gem 'rack-cors', require: 'rack/cors'。我做了捆绑安装。

我还在 config/initializers/cors.rb 中进行了设置

Rails.application.config.middleware.insert_before 0, Rack::Cors do
  allow do
    origins '*'

    resource '*',
      headers: :any,
      methods: [:get, :post, :put, :patch, :delete, :options, :head]
   end
 end

之后我确实重新启动了服务器。

这是我得到的错误：

Access to XMLHttpRequest at 'localhost:3000/articles' from origin 'http://localhost:8080' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
