  </ul>
  <p>技巧等级：中级</p>
<p>文件预处理配置文件为default.filecap，每行格式如下：<br>
[文件后缀]:[mimetype]:[处理命令]</p>
<p>其中文件后缀可允许最多两段后缀，譬如&quot;txt.xz&quot;,&quot;html.gz&quot;。<br>
mimetype表示命令处理后的输出内容格式。<br>
处理命令与<a href="../cmd/index.html#">default.cmds</a>相同，主要可能用到如下替换：<br>
%u（网址或文件路径）、%U（编码以后的网址）、%c（当前网址cookie）、%p（密码保护网站中的密码，curl格式）。</p>
<p>利用文件预处理，<a href="../index.html#">超微浏览器</a>现在可以预览/查看/播放一切可下载资源，并且可以利用不同网站在线服务预览不同的文件，而手机上一个应用都不用装。</p>
<p>配置default.filecap如下：</p>
<pre><code>txt:text/html:curl %p "%u"
mp3:text/html:echo '&lt;audio controls width=100% height=100%>&lt;source src="%u">&lt;/audio>'
m4b:text/html:echo '&lt;audio controls width=100% height=100%>&lt;source src="%u">&lt;/audio>'
m3u8:text/html:echo '&lt;video controls width=100% height=100%>&lt;source src="%u">&lt;/video>'
mp4:text/html:echo '&lt;video controls width=100% height=100%>&lt;source src="%u">&lt;/video>'
mkv:text/html:echo '&lt;video controls width=100% height=100%>&lt;source src="%u">&lt;/video>'
doc:uweb:echo https://view.xdocin.com/view?src=%U
xls:uweb:echo https://view.xdocin.com/view?src=%U
ppt:uweb:echo https://view.xdocin.com/view?src=%U
docx:uweb:echo https://view.xdocin.com/view?src=%U
xlsx:uweb:echo https://view.xdocin.com/view?src=%U
pptx:uweb:echo https://view.xdocin.com/view?src=%U
xz:text/plain:curl %p "%u"|xz -d --</code></pre>
<p>安装过相应的<a href="../html5/index.html#">html5应用</a>，则如下配置阅读相应格式文件：</p>
<pre><code>pdf:uweb:echo file:///data/data/info.torapp.uweb/files/app/pdf.js/web/viewer.html?file=%u
djvu:uweb:echo file:///data/data/info.torapp.uweb/files/app/djvu.html?url=%u
epub:uweb:echo file:///data/data/info.torapp.uweb/files/app/reader/index.html#?bookPath==%u</code></pre>
<p>长按设置按钮，勾选“文件预处理”，清后台重启浏览器。则网页上点击下载按钮时上述文件类型会自动预览。</p>
<p>如果用户配置中处理命令用到curl，则需要安装<a href="../gnuplot/index.html#">Termux</a>，并在Termux中安装curl (&quot;apt install curl&quot;)。<br>
如果用户不安装Termux，则上述配置命令中的&quot;am&quot;需要全部路径，需用&quot;/system/bin/am&quot;替换。</p>
<p>使用微软服务预览office文档 (https://view.officeapps.live.com/op/view.aspx?src=)必需当前UA为PC，否则会出现空白页面。有条件的用户建议使用google docs (&quot;http://docs.google.com/gview?embedded=true&amp;url=&quot;) 服务替换。</p>
<p>若使用手机应用预览文件，则docx处理命令可改为：</p>
<pre>am start --user 0 -a android.intent.action.VIEW -d "%u" -t "application/docx"</pre>
<p>其余常见文件的类型名：<br>
application/msword<br>
application/msexcel<br>
application/pdf</p>
<p>目前已知服务：<br>
google docs, 功能强大，可查看几乎一切文档，但 &quot;我的所爱在山腰，想要得到山太高。&quot;</p>
<p>微软office, 可预览office文档，ua必须是pc。</p>
