同问

部署到nginx转发api会出现重复头
2024/07/30 08:27:20 [error] 13272#15132: *18 upstream sent duplicate header line: "Content-Length: 8474", previous value: "Content-Length: 8474" while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /ls/api/admin/Statement/download/id/19.xlsx?batoken=4a4f7907-ce10-45c3-82ce-8d2cf3d35ced&server=1 HTTP/1.1", upstream: "http://127.0.0.1:8000/admin/Statement/download/id/19.xlsx?batoken=4a4f7907-ce10-45c3-82ce-8d2cf3d35ced&server=1", host: "localhost"

        // 避免输出到命令行窗口
        while (ob_get_level() > 1) {
            ob_end_clean();
        }

        ob_start();

        $http     = $app->http;
        $response = $http->run();
        $content  = ob_get_clean();

        ob_start();
        $response->send();
        $app->http->end($response);
        $content .= ob_get_clean() ?: '';

        $connection->send(new Response($response->getCode(), $response->getHeader(), $content));

        这里对于文件输出可能重复头了。

        $responseClass = get_class($response);
        $headers = $response->getHeader();
        if (isset($headers['Content-Length'])) {
            unset($headers['Content-Length']);
        }
        if ($responseClass !== 'think\response\File') {
            $connection->send(new Response($response->getCode(), $response->getHeader(), $content));
        }
        else {
            $connection->send(new Response($response->getCode(), $headers, $content));
        }
