webman跨域相关问题

2023年9月13日14:14:05

webman版本1.5

php版本8.0

运行环境windows

测试项目：https://gitee.com/open-php/zx-webman-website

webman在跨域的时候，会有点不同因为第一个区别就是是否关闭自动路由

复制代码

//关闭自动路由
Route::disableDefaultRoute();

如果不关闭路由只要简单的在路由上挂上跨域中间件,如果开启自动路由，就在config/middleware.php添加就可以了

复制代码

return [
    '' => [
        app\middleware\CrossDomain::class,//跨域请求
    ]
];

CrossDomain中间件的代码

复制代码

<?php

namespace app\middleware;

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

//跨域
class  CrossDomain implements MiddlewareInterface
{
    public function process(Request $request, callable $next): Response
    {
//        p(getTime() . self::class);
        // 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
        $response = strtoupper($request->method()) === 'OPTIONS' ? response('', 204) : $next($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;
    }
}

如果关闭自动路由挂在中间件就如下：

复制代码

Route::group('/open', function () {

    Route::get('/test', [app\controller\Web\TestController::class, 'index'])->name('测试');
    Route::post('/uploadPic', [app\controller\Web\IndexController::class, 'uploadPic']);//上传图片文件
    Route::post('/uploadFile', [app\controller\Web\IndexController::class, 'uploadFile']);//上传普通文件
})->middleware([
    app\middleware\CrossDomain::class,
    app\middleware\ApiLog::class
]);

关闭自动路由的情况下需要额外配置一点东西
