Question

我有2个Rails应用程序，App1和App2。

App1包含指向App2中控制器操作的链接，后者又返回文件（下载），例如：

<%= link_to "Download Video", "http://app2/downloads/download_video", :target => "_bkank" %>

在App2中有“downloads”和控制器，“download_video”是“downloads”控制器的一个动作：

def download_video
    send_file  '/path/to/video/video.mp4', type: "video/mp4", :disposition => "inline"
end

单击链接后，将打开一个新窗口（选项卡）并在窗口中播放视频 - 这是一种理想的行为....我的问题是，当查看日志时，我看到相同的GET请求被发送3次 - 第一次作为HTML，然后作为 / 两次：

Started GET "/downloads/download_video" for ::1 at 2018-04-19 16:26:45 +0200
Processing by DownloadsController#download_video as HTML
Sent file /path/to/video/video.mp4 (0.2ms)
Completed 200 OK in 1ms


Started GET "/downloads/download_video" for ::1 at 2018-04-19 16:26:46 +0200
Processing by DownloadsController#download_video as */*
Sent file /path/to/video/video.mp4 (0.1ms)
Completed 200 OK in 1ms


Started GET "/downloads/download_video" for ::1 at 2018-04-19 16:26:46 +0200
Processing by DownloadsController#download_video as */*
Sent file /path/to/video/video.mp4 (0.1ms)
Completed 200 OK in 0ms

有谁能让我知道为什么会这样，我怎么能阻止它？

谢谢，乔恩。

@ praga2050，

请你发布整个控制器代码......

是的：

class DownloadsController < ApplicationController
    def download_video
        send_file  '/var/www/videos/video.mp4', type: "video/mp4", :disposition => "inline"
    end
end

@ praga2050，

...尝试使用时间戳添加Rails.logger.debug并查看

是的：

Rails发送多个GET开始的文件
