Access-Control-Allow-Origin 包含无效值

Question

当我在 angular 2 中使用 http 服务发送请求时，浏览器显示以下错误。谁能告诉解决方案？？？

XMLHttpRequest cannot load http://192.168.1.59:1340/User/add. Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains the invalid value ''. Origin 'http://192.168.1.59:8083' is therefore not allowed access.

Answer 1

您需要服务器启用 CORS（跨源资源共享）

参考：http://sailsjs.org/documentation/concepts/security/cors

只需在config/cors.js中启用allRoutes: allRoutes: true

Answer 2

您需要在 config/cors.js 文件中启用 cors

allRoutes: false, // Change to true if you want to enable cors in all routes.


origin: 'https://myapp.com,https://auth.myapp.com' // use * for any origin.

如果您只想为特定路由启用 cors，请在 config/routes.js

'get /foo/bar': {
    controller: 'FooController',
    action: 'bar',
    cors: true
  },

Access-Control-Allow-Origin 包含无效值

Access-Control-Allow-Origin contains invalid value
