TP6自帶的跨域中間件無法使用的個人解決方法

使用TP6,因為需要跨域上傳圖片,一直不成功,網上搜了好久,方法都沒解決跨域上傳文件

比如下面的方式沒成功

$this->app     = $app;
$this->request = $this->app->request;

// 支持跨域請求的host數組['a.cn', 'b.cn']
$corsHost = config('mysite.cors_host');

if (!empty($corsHost) && is_array($corsHost) && in_array($this->request->host(), $corsHost)) {

    header("access-control-allow-headers: Accept,Authorization,Cache-Control,Content-Type,DNT,If-Modified-Since,Keep-Alive,Origin,User-Agent,X-Mx-ReqToken,X-Requested-With");
    header("access-control-allow-methods: GET, POST, PUT, DELETE, HEAD, OPTIONS");
    header("access-control-allow-credentials: true");
    header('Access-Control-Allow-Origin: ' . $this->request->domain());
}

if($this->request->isOptions()) {
    exit;
}

發現 問題出在 $this->request->domain() ,返回的結果一直是請求地址,

比如 a.cn跨域訪問b.cn的資源, $this->request->domain() 值為 b.cn ,但是Access-Control-Allow-Origin需要返回的是a.cn

 

最后只能這樣了

$this->app     = $app;
$this->request = $this->app->request;

// 支持跨域請求的host數組['a.cn', 'b.cn']
$corsHost = config('mysite.cors_host');

if (!empty($corsHost) && is_array($corsHost) && isset($_SERVER['HTTP_ORIGIN']) && in_array(parse_url($_SERVER['HTTP_ORIGIN'], PHP_URL_HOST), $corsHost)) {

    header("access-control-allow-headers: Accept,Authorization,Cache-Control,Content-Type,DNT,If-Modified-Since,Keep-Alive,Origin,User-Agent,X-Mx-ReqToken,X-Requested-With");
    header("access-control-allow-methods: GET, POST, PUT, DELETE, HEAD, OPTIONS");
    header("access-control-allow-credentials: true");
//            header('Access-Control-Allow-Origin: ' . $this->request->domain());
    header('Access-Control-Allow-Origin: ' . $_SERVER['HTTP_ORIGIN']);
}

if($this->request->isOptions()) {
    exit;
}
