这样的影视应用需要对视频进行刮削，对于电视剧来说还是有些不一样的，<br>比如我要刮削这部经典电视剧纪晓岚<br><img data-src=https://img.nicksxs.com/blog/gzJIWi.png><br>像这样的命名方式在 tmm 中是无法识别的，或者就得一集一集进行制定刮削，<br><img data-src=https://img.nicksxs.com/blog/S5UtuM.png><br>所以第一步需要进行改名<br>比如这是第一季的，那就是 S01，然后按集数 E01，第一季第一集的文件名就是 S01E01.mkv<br>然后右键点击搜索刮削，默认会以文件夹名进行搜索，是在 tmdb 数据库进行搜索<br><img data-src=https://img.nicksxs.com/blog/hExmO7.png><br>这样除非文件夹名很符合要求，一般都刮削不出来，所以需要有两种刮削方式，一种就是比较标准的命名，这样的名字可以手动先去豆瓣或者 tmdb 搜索，另一个种也可以在豆瓣找到 imdb 的 id 进行搜索<br><img data-src=https://img.nicksxs.com/blog/gUhZNC.png><br>但有时候也会搜不到，比如这个纪晓岚就是搜不到，但是之前的一些韩剧什么的很多都能搜到<br><img data-src=https://img.nicksxs.com/blog/hN7XEL.png><br>这个其实是最基本的刮削，但是这样刮削了需要在 jellyfin 那取消元数据下载<br><img data-src=https://img.nicksxs.com/blog/4oXenN.png>，这样就不会被覆盖</div><footer class=post-footer><div class=post-eof></div></footer></article></div><div class=post-block><article

itemprop=articleBody><p>这个可能是个很简单的点，不过之前碰到了就记录下，我们常规的应用都是使用统一的请求响应转换器去处理请求和响应返回，但是对于有文件上传或者返回的是文件的情况，一般都是不使用统一的处理，但是在响应返回的时候可能会存在这样的情况，如果文件正常被处理那就返回文件，如果处理异常需要给前端返回 json类型的响应，里面能够取到响应码错误描述等<p>比如在请求中参数就使用 <code>httpRequest(HttpServletRequest request, HttpServletResponse response)</code><br>然后在返回的时候就使用 <code>response.getOutputStream().write(result)</code>，而如果是要返回

个sata盘位，用一个 ssd 做系统盘，是挺不错的，但是如果是像我这样的要搞盘位比较多的nas，发现有一系列的不足点，<br>1、 前面有讲过，网卡问题，用的是 RTL 瑞昱的网卡，目前知道的最高能支持的 exsi 的版本是 6.7，再高的版本就不支持了，不过其实真的想用的话，6.7 版本也是可以用的，只是我当时是打包的 8.0 的系统，个人也不太喜欢用比较低版本的，所以算是一个不足点<br>2、 第二点是m.2插槽，只有一个m.2也是很难理解的，一个做系统盘，另一个可以作为简单的数组存储，或者作为群晖的下载缓存，如果只有一个的话特别是现在这个 ssd 的价格这么低了，加一个还是很香的，这个问题跟后面也是有点关系的<br>3、 PCIE 的插槽，这个主板只支持两个 PCIE 3.0 x1 的，它能支持 1Gbps 的传输速度，后面我买了个 PCIE 3.0 x1 转 m.2 的转接卡，这样其实真的是把速度拖慢了很多，还有一个 PCIE 3.0 X16 的，这是用来装显卡的，只用来扩展做个m.2或者 sata 又感觉很浪费，而且说不定未来会装个显卡<br>4、 风扇口的问题，风扇接口其实原来一直没概念，我在这次装 nas 之前其实自己没有完整装个台式机过，之前买的目前在使用的主力机两个风扇在换了的时候才知道是用的大 4pin 接口串接的，其中一个有 pwm 的接口也没用，这样就没办法用主板自带调速软件来进行自动或者手动调速，有时候比如晚上不关机，放在房间里风扇声很大还是挺吵的，这个主板只有两个风扇接口，一个是 cpu 的，一个是系统风扇，其实就只有一个可以用了<br>主要是以上几个点，所以我一直在关注二手主板，之前买了个华硕的 z370 tuf gaming，没想到点不亮，也不知道什么原因，还害我吓得以为 cpu 被我弄坏了，后面慢慢在网上看着发现有一块微星的 z390 TOMAHAWK战斧导弹，各方面接口都很不错，而且还有个千兆网口，在闲鱼蹲了很久终于在前不久蹲到了，买回来赶紧看看能不能点亮，结果一把点亮，还是用的螺丝刀开机的，就心里暗爽感觉捡到了宝，但是装进我的半岛铁盒 F10 机箱就发现跪了，出现的这个问题原来在网上哪里看到过，一直没注意，就是 sata 接口的方向，因为一个是 matx 的板，装进去即使 sata 接口的方向是跟主板平行的也留着足够的空间，但是 atx 板装上之后，大概只有 2 厘米左右的空间并且是两个叠着的端口，一个可能要能硬拗一下，但是两个我试了下，只能识别出一个，这个真让我翻了个大车，而且其实我换这个主板其实还有个大问题，就是我是在 Windows 下的vmware workstation 虚拟机里通过sata 直通，但是这个是认硬盘接口的，也就是顺序是有影响的，换了主板发现也不能支持，后面可能真的想用的话还得重新搞黑裙，要把数据备份出来，幸好换回原来的主板还能用，所以硬件也不能只看性能和接口丰富度，要看适配的其他硬件的合适度以及原先已经有的软件系统</div><footer class=post-footer><div

itemprop=articleBody><p>上次说 nas 的方案我是在 win10 下使用vmware workstation 搭建的黑裙虚拟机，采用 sata 物理磁盘直通的方式，算是跑通了黑裙的基础使用模式，但是后来发现的一个问题是之前没考虑到的，我买了不带 f 的处理器就是为了核显能做硬解，但是因为 cpu 是通过 vmware 虚拟的，目前看来是没法直通核显的，我是使用的 jellyfin 套件，一开始使用是默认的刮削方式，而且把电视剧当成了电影在刮削，所以基本不能看，后面使用了 tmm 作为刮削工具，可以手动填写 imdb 的id 来进行搜索，一般比较正式的剧都可以在豆瓣上找到的，然后让 jellyfin 只作为媒体管理器，但是前面的问题还是没解决，所以考虑了下可以在win10 下直接运行 jellyfin，媒体目录使用挂载在 nas 里的盘，这样 jellyfin 就能直接调用核显了，也算是把 win10 本身给利用起来了，并且文件的管理还是在黑裙中。<br>现在想来其实我这个方案还是不太合理，cpu 性能有点过剩想通过虚拟机的形式进行隔离使用，但是购买带核显的 cpu 最大的目的却没有实现，如果是直接裸机部署黑裙的话，真的是觉得 cpu 有点太浪费了，毕竟 passmark评分有 1w3 的cpu，只用来跑黑裙，所以网上的很多建议也是合理的，不过我可能是 win10 用的比较多了，还是习惯有 win 的环境。</div><footer class=post-footer><div class=post-eof></div></footer></article></div><nav class=pagination><span class="page-number
