問題描述

webman 控制器返回遠(yuǎn)程服務(wù)器的文件流,參考了帖子
http://wtbis.cn/q/13212

程序代碼或配置

public function streamFile()
    {
        $http = new \Workerman\Http\Client();
        $url ='https://xxxx.cn/uploads/default/2024-10/09/670629b1d8f8a.jpeg';
        $connection = \request()->connection;
        // $http = new Client();
        $http->request($url, [
            'method' => 'GET',
            'progress' => function($buffer) use ($connection) {
            print_r($buffer);
                $connection->send(new \Workerman\Protocols\Http\Chunk($buffer));
            },
            'success' => function($response) use ($connection) {
                $connection->send(new \Workerman\Protocols\Http\Chunk('')); // 發(fā)送空的的chunk代表response結(jié)束
            },
        ]);
        $downloadName = uniqid().'.jpeg';
        return response()->withHeaders([
            "Content-Type" => "application/jpeg",
            "Transfer-Encoding" => "chunked",
            "Content-Disposition"=>"attachment;filename=\"$downloadName\""
        ]);
    }

請求后下載的是一個(gè)空文件，
progress 回調(diào)內(nèi)也是可以讀取到文件的二進(jìn)制內(nèi)容的，

操作系統(tǒng)環(huán)境及workerman/webman等具體版本

win10 調(diào)試
PHP 8.0.2
"workerman/http-client": "^2.2",
"workerman/webman-framework": "^1.5",
本地調(diào)試，沒有使用nginx 作為反向代理
