Question

我正在使用以下方法在后端服务器关闭时提供良好的回退错误消息。

问题是浏览器将响应下载为文件，而不是显示为HTML响应。

 location @fallback {
        echo_status 504;
        add_header Content-Type: "text/html; charset=UTF-8";

        echo "<!DOCTYPE html>";
        echo "<html lang='en'>";
        echo "  <head>";
        echo "    <meta charset='utf-8'>";
        echo "    <title>Backend is down</title>";
        echo "  </head>";
        echo "  <body>";
        echo "    Backend service is offline, please retry in few minutes. $echo_timer_elapsed";
        echo "  </body>";
        echo "</html>";
    }

    location / {
            error_page 502 504 = @fallback;
            proxy_connect_timeout   10s;
            proxy_pass              http://backend:8090;
            proxy_read_timeout      10800s;
    }

如何强制nginx内联响应而不是下载？
