跨域配置

跨域介绍

通过中间件+路由配置实现跨域如果在线上环境使用，请将验证码模式设置为 redis 模式

跨域中间件

1、系统已内置跨域中间件CrossDomain.php, 内容如下：

php

namespace plugin\saiadmin\app\middleware;

use Webman\Http\Request;
use Webman\Http\Response;
use Webman\MiddlewareInterface;

/**
 * 跨域中间件
 */
class CrossDomain implements MiddlewareInterface
{
    public function process(Request $request, callable $handler) : Response
    {
        // 如果是options请求则返回一个空响应，否则继续向洋葱芯穿越，并得到一个响应
        $response = $request->method() == 'OPTIONS' ? response('') : $handler($request);

        // 给响应添加跨域相关的http头
        $response->withHeaders([
            'Access-Control-Allow-Credentials' => 'true',
            'Access-Control-Allow-Origin' => $request->header('origin', '*'),
            'Access-Control-Allow-Methods' => $request->header('access-control-request-method', '*'),
            'Access-Control-Allow-Headers' => $request->header('access-control-request-headers', '*'),
        ]);

        return $response;
    }
}

2、如果使自己的插件或者应用全局跨域，则需要在插件或者应用的config/middleware.php中配置：

php

use plugin\saiadmin\app\middleware\CrossDomain;

return [
    '' => [
        CrossDomain::class,
    ]
];

3、在插件或者应用路由中配置，文件位置：config/route.php：

php

use Webman\Route;

Route::fallback(function() {
    $response = request()->method() == 'OPTIONS' ? response('') : json(['code' => 400, 'message' => '异常请求']);
    $response->withHeaders([
        'Access-Control-Allow-Credentials' => 'true',
        'Access-Control-Allow-Origin' => request()->header('origin', '*'),
        'Access-Control-Allow-Methods' => request()->header('access-control-request-method', '*'),
        'Access-Control-Allow-Headers' => request()->header('access-control-request-headers', '*'),
    ]);
    return $response;
});


// 此处配置的路由全部能够跨域
Route::group('/api', function () {
    // 数据字典
    Route::get("/common/dict",[\plugin\saiuser\app\controller\CommonController::class, 'dictData']);
    Route::get("/common/dictAll",[\plugin\saiuser\app\controller\CommonController::class, 'dictAll']);
    
    ......
