已經(jīng)在php接口文件中添加：

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

然而前端調(diào)用接口請(qǐng)求數(shù)據(jù)時(shí)仍然報(bào)錯(cuò)：

Failed to load http://aaa.com/version?test=1: Redirect from 'http://aaa.com/version?test=1' to 'http://bbb.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://ccc.com' is therefore not allowed access.
