跨域問題服務端解決辦法 Request header field Authorization is not allowed by Access-Control-Allow-Headers

跨域問題服務端解決辦法

一般在入口文件加

header('Access-Control-Allow-Origin:*');
// 響應類型
header('Access-Control-Allow-Methods:*');
// 響應頭設置
header('Access-Control-Allow-Headers:content-type,token,id');
header("Access-Control-Request-Headers: Origin, X-Requested-With, content-Type, Accept, Authorization");
都能解決，要是不行試試下面

if($_SERVER['REQUEST_METHOD'] == 'OPTIONS'){
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
header('Access-Control-Allow-Methods: GET, POST, PUT,DELETE,OPTIONS,PATCH');
file_put_contents('option.txt',json_encode($_REQUEST));
exit;
}

header('Access-Control-Allow-Origin:*');
// 響應類型
header('Access-Control-Allow-Methods:*');
// 響應頭設置
header('Access-Control-Allow-Headers:content-type,token,id');
header("Access-Control-Request-Headers: Origin, X-Requested-With, content-Type, Accept, Authorization");
