ThinkPHP中跨域请求设置的几种方式

public function yourMethod()
{
    // 设置允许所有来源的请求
    header('Access-Control-Allow-Origin: *');
    // 设置允许的请求方法
    header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
    // 设置允许的请求头
    header('Access-Control-Allow-Headers: Content-Type, Authorization');

    // 其他业务逻辑代码
    return json(['message' => '跨域请求成功']);
}

php think make:middleware CorsMiddleware

<?php

namespace app\middleware;

class CorsMiddleware
{
    public function handle($request, \Closure $next)
    {
        // 设置允许所有来源的请求
        header('Access-Control-Allow-Origin: *');
        // 设置允许的请求方法
        header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
        // 设置允许的请求头
        header('Access-Control-Allow-Headers: Content-Type, Authorization');

        if ($request->method() === 'OPTIONS') {
            // 对于预检请求，直接返回200状态码
            return response('', 200);
        }

        return $next($request);
    }
}

return [
    // 其他中间件...
    app\middleware\CorsMiddleware::class,
];
