CORS交叉 - 帆中的原点飞行前错误

CORS cross - origin preflight error in sails

本文关键字：原点 飞行前 错误 交叉 CORS      更新时间：2023-09-26

我是第一次创建混合应用程序，并开始遵循几个教程。我在浏览器控制台上收到这些错误

Refused to load the script 'http://192.168.1.142:35729/livereload.js?snipver=1' because it violates the following Content Security Policy directive: "script-src 'self' 'unsafe-inline' 'unsafe-eval'".
XMLHttpRequest cannot load http://localhost:1337/auth/local. The request was redirected to 'http://localhost:1337/login', which is disallowed 
for cross-origin requests that require preflight.

我在服务器端使用 sails，并在路由表中添加了以下内容

'get /' : {
  cors: {
    origin: '*'    
  },
  controller: 'FlashController',
  action: 'home'
},
'post /auth/local' : {
  cors: {
    origin: '*'    
  },
  controller: 'AuthController',
  action: 'callback'
},
'get /login' : {
  cors: {
    origin: '*'    
  },
  controller: 'AuthController',
  action: 'login'
},

当我按照教程进行操作时 devdactic.com/user-auth-angularjs-ionic/并对应用程序进行了以下更改以允许 CORS

ionic plugin add cordova-plugin-whitelist

以下是我的配置.xml

删除

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">

编译时重新添加
