Access to XMLHttpRequest at 'http://*******' from origin 'http://localhost:8091' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

解决方案

• application/tags.php

return [
    // 应用初始化
    'app_init'     => [
        'app\\common\\behavior\\CORS'
    ],

];

• application/common/behavior/CORS.php

namespace app\common\behavior;

use think\Response;
class CORS
{
    public function appInit()
    {
        // Allow from any origin
        if (isset($_SERVER['HTTP_ORIGIN'])) {
            // Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one
            // you want to allow, and if so:
            header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
            header('Access-Control-Allow-Credentials: true');
            header('Access-Control-Max-Age: 86400');    // cache for 1 day
        }

        // Access-Control headers are received during OPTIONS requests
        if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

            if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
                // may also be using PUT, PATCH, HEAD etc
                header("Access-Control-Allow-Methods: GET, POST, OPTIONS");

            if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
                header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

            exit(0);
        }

    }
