跨域问题服务端解决办法

一般在入口文件加

header('Access-Control-Allow-Origin:*');
// 响应类型
header('Access-Control-Allow-Methods:*');
// 响应头设置
header('Access-Control-Allow-Headers:content-type,token,id');
header("Access-Control-Request-Headers: Origin, X-Requested-With, content-Type, Accept, Authorization");

都能解决，要是不行试试下面

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:*');
// 响应类型
header('Access-Control-Allow-Methods:*');
// 响应头设置
header('Access-Control-Allow-Headers:content-type,token,id');
header("Access-Control-Request-Headers: Origin, X-Requested-With, content-Type, Accept, Authorization");
