前端項目跨域請求報錯

在開發VUE前端項目訪問服務端的接口的時候報錯：

Access to fetch at

'https://xxx.xxx.com/xxx/xxx/xxx?param=xxx' from origin 'http://xxx.xxx.com:xxx'

has been blocked by CORS policy:

Request header field content-type is not allowed by Access-Control-Allow-Headers in preflight response.

大致意思是：是一個跨域請求我的沒有訪問該地址的權限（接口服務器采用的是PHP編寫）

 

解決方案：

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Access-Control-Allow-Methods: GET, POST, PUT');
