    <content type="html"><![CDATA[<p>被坑了两天。。感觉这个必须得记下了。。。</p>

<p>使用 retrofit2 上传一张图到服务器，服务器上使用这样的 php 语句来获取文件</p>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
</pre></td><td class='code'><pre><code class=''><span class='line'>$file = $_FILES['image'];
</span><span class='line'></span></code></pre></td></tr></table></div></figure>


<p>ApiService 按照官方的文档使用<code>Multipart</code>就好，用不用 PartMap 就看喜好了</p>

<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>

</span></code></pre></td></tr></table></div></figure>


<p>所有的参数都要用<code>RequestBody</code>包装一下</p>

<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>

</span></code></pre></td></tr></table></div></figure>


<p>然后把它们加入 PartMap ，如果不使用 PartMap ，把对应部分填到 @Part(&ldquo;field&rdquo;) 里去也可以</p>

<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
<span class='line-number'>4</span>
</pre></td><td class='code'><pre><code class='Java'><span class='line'><span class="n">Map</span><span class="o">&lt;</span><span class="n">String</span><span class="o">,</span> <span class="n">RequestBody</span><span class="o">&gt;</span> <span class="n">partMap</span> <span class="o">=</span> <span class="k">new</span> <span class="n">HashMap</span><span class="o">&lt;&gt;();</span>
</span><span class='line'><span class="n">partMap</span><span class="o">.</span><span class="na">put</span><span class="o">(</span><span class="s">&quot;apikey&quot;</span><span class="o">,</span> <span class="n">apikey</span><span class="o">);</span>
</span><span class='line'><span class="n">partMap</span><span class="o">.</span><span class="na">put</span><span class="o">(</span><span class="s">&quot;use&quot;</span><span class="o">,</span> <span class="n">use</span><span class="o">);</span>
</span><span class='line'><span class="n">partMap</span><span class="o">.</span><span class="na">put</span><span class="o">(</span><span class="s">&quot;image\&quot;; filename=\&quot;upload.jpg\&quot;&quot;</span><span class="o">,</span> <span class="n">imgFile</span><span class="o">);</span>
</span></code></pre></td></tr></table></div></figure>


<p>然后把这个 partMap 传入对应函数中，大功告成。。。</p>

<p><del>看起来很简单就像是 FormUrlEncoded 一样，然而，发现坑没有？</del></p>

<p><strong>注意：</strong>在传入文件的时候，使用</p>

<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='Java'><span class='line'><span class="n">partMap</span><span class="o">.</span><span class="na">put</span><span class="o">(</span><span class="s">&quot;image\&quot;; filename=\&quot;upload.jpg\&quot;&quot;</span><span class="o">,</span> <span class="n">imgFile</span><span class="o">);</span>
</span></code></pre></td></tr></table></div></figure>


<p>实际上，上传的文件名与系统中存储的文件的真实文件名没有关系，只与这个字符串有关系。。。  <br/>
所以，如果需要在服务器上使用<code>$_FILES['参数名']</code>来获取上传的文件，那么上传的时候就应该写</p>

<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
<span class='line-number'>4</span>
<span class='line-number'>5</span>
</pre></td><td class='code'><pre><code class='Java'><span class='line'><span class="c1">// 使用 PartMap </span>
</span><span class='line'><span class="n">partMap</span><span class="o">.</span><span class="na">put</span><span class="o">(</span><span class="s">&quot;参数名\&quot;; filename=\&quot;文件名\&quot;&quot;</span><span class="o">,</span> <span class="n">imgFile</span><span class="o">);</span>
</span><span class='line'>
</span><span class='line'><span class="c1">// 直接在定义 ApiService 时使用 @Part 注释</span>
</span><span class='line'><span class="n">Call</span><span class="o">&lt;...&gt;</span> <span class="nf">upload</span><span class="o">(...,</span> <span class="nd">@Part</span><span class="o">(</span><span class="s">&quot;参数名\&quot;; filename=\&quot;文件名\&quot;&quot;</span><span class="o">)</span> <span class="n">RequestBody</span> <span class="n">file</span><span class="o">,</span> <span class="o">...);</span>
</span></code></pre></td></tr></table></div></figure>


<p>因此，如果需要文件名可变，那么就必须使用 PartMap</p>

<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='Java'><span class='line'><span class="n">partMap</span><span class="o">.</span><span class="na">put</span><span class="o">(</span><span class="s">&quot;参数名\&quot;; filename=\&quot;&quot;</span> <span class="o">+</span> <span class="n">filename</span> <span class="o">+</span> <span class="s">&quot;\&quot;&quot;</span><span class="o">,</span> <span class="n">imgFile</span><span class="o">);</span>
</span></code></pre></td></tr></table></div></figure>

    <content type="html"><![CDATA[<p><a href="http://hackspire.unsads.com/wiki/index.php/Main_Page">HackSpire</a> 一直处于挂掉的状态，这使得很多 Nspire 的资料无法搜寻。今天 MetroStyle 突然发现了 archive.org 上缓存过 HackSpire 的镜像，但是要使用<del>科学的上网方式</del>才能访问而且速度很慢确实也不太方便。于是就在自己的阿里云服务器上弄了一个。</p>

<p>实际上就是查看镜像站的源代码界面然后直接贴到一个空白的 MediaWiki 上。</p>

<p><del>好歹能看吧</del>。。。</p>

<p>再次感谢 MetroStyle ，他提供的站点导出文件使得当前的 HackSpire 镜像站十分完整了。</p>

    <content type="html"><![CDATA[<p>最近有人发现，将 TI-Nspire CX CAS 升级到 OS 4.0.3.29 之后出现了无法安装字典的问题，我在 firebird 上使用字典安装程序，然后发现这实际上是防降级机制的问题。  <br/>
因为 OS 4.0 实际上有两个版本，官网上直接下载到的是 OS 4.0.3.29 ，而教师软件里自带的是 OS 4.0.0.235 。而教师软件自带了一个版本号是 4.0.0.500 的 ZiDian.tcc ，因此在 4.0.3.29 上直接安装这个 ZiDian.tcc 会触发防降级机制，并不会被安装。  <br/>
我在 firebird 里安装了一个 OS 4.0.0.235 ，然后在里面安装了字典，然后我发现安装过程中会有这样的输出。</p>

<p>原来字典安装字典的主要过程就是解压+复制+验证的过程，如果把 ZiDian.tcc 以 zip 解压，我们会得到一个 os_ext.img 再解压它，得到的恰好就是这些文件，那就简单了。把这些文件直接复制到对应文件夹里试试。  <br/>
于是我写了个简单的 Ndless 程序<del>（好吧其实是拿以前写的复制文件代码随便改改出来的）</del>，来完成这个复制操作</p>

<p>考虑到 Nspire 只能传输 .tns 文件。所以必须在传入之前加上这个后缀，复制的时候再把它处理掉。  <br/>
把从 ZiDian.tcc 中得到的所有文件加个 .tns 后缀，放到 我的文档 下面的 dict 文件夹，然后运行一下这个程序，效果相当不错！  <br/>

重启一下，字典就可以用了。  <br/>

    <link href="http://www.caoyue.com.cn/blog/2015/09/17/coolpad-5261-de-root-yu-shua-ji-fang-fa/"/>
    <updated>2015-09-17T13:31:28+08:00</updated>
    <id>http://www.caoyue.com.cn/blog/2015/09/17/coolpad-5261-de-root-yu-shua-ji-fang-fa</id>
    <content type="html"><![CDATA[<p>其实这篇文章没有什么技术含量的。。。用的工具、文件什么的差不多都是现成的。。。<br />
写这篇文章的纯粹目的，只是因为网上几乎没有这部手机相关的东西，放一个作为一个备忘，顺便为以后破解国产机提供一种思路。<br />
<br />
首先说一下这部机子的来历：我们学校的电信宽带是办宽带赠(kun)送(bang)手机的，由于本来有手机就选了个最便宜的，于是就拿到了这部“连官网上都找不到的机子”<br /></p>

<div>
<img src="http://www.caoyue.com.cn/images/blog/20150917/001.jpg" style="height: 40%; width: 40%; float: left ;" />
<img src="http://www.caoyue.com.cn/images/blog/20150917/002.jpg" style="height: 40%; width: 40%; float: left ;" />
</div>


<p><div style="clear: both; " />
<br />
到手的时候真是有一种“用之无味，弃之可惜”的感觉了。本来办宽带的学长说可以少35元回收掉，但是想想当时说的<del>豪言壮志</del>“这种机子就是拿来耍的”，那就还是耍一耍吧！<br />
<!--more-->
<br />
配置的话 512 MB RAM ，CPU 是高通的 MSM8909<del>（这是什么鬼？）</del>，系统是 Android 4.4 ，df 命令显示有 775MB 的 /system 分区以及 248M 的 /cache 分区 ，另外这货的 /data 分区和内置存储卡是共用空间的（虽然只有 1.6GB ），令人惊讶是这货居然支持 zram 和 swap 。。。<br />
<br />
好吧，废话+吐槽到此结束。。。<br />
<br />
首先，这部机子虽说在学校稍微普遍一点（电信赠(kun)送(bang)的影响），但在网上几乎找不到，还好有位好心人上传了个 <a target="_blank" href="http://pan.baidu.com/s/1mgMoxSG">5261售后专用线刷救砖包.zip</a> ，用 MiFlash 就可以给这部手机刷机了<del>（怎么又和小米扯上关系了）</del>。<br />
<br />
不管怎么样，先刷了再说。。。<br />
<br />
按照它提供的方法，装好驱动（Windows 8 需要关闭驱动强制签名）和 MiFlash ，把 5261售后专用线刷救砖包.zip/酷派进Qdload模式用MIFLASHTOOL刷.zip/酷派进Qdload模式/ 下面的 #dload#.d 和 !dload!.l 拷贝到 SD 卡，插拔一次电池，将手机连接电脑，打开MiFlash，点几下[刷新]，然后选择那个有刷机文件的文件夹，点击[刷机]就开刷了。。。<br />
<br />
刷好之后，拔下 SD 卡，长按电源键就可以开机，话说第一次开机确实挺久的。。。<br />
<br />
一进系统，发现系统果然变了不少，以前只有企鹅管家，现在居然上了大数字全家桶，看来那些国厂为了我国国民信息安全真是费(shang)尽(xin)心(bing)机(kuang)！！！<br />
<br />
不过倒是终于找到了一种能改系统的方法，<del>那就好办多了</del>。<br />
<br />
本来的想法是先把刷机包里的 system_1.img 到 system_7.img 合并一下，到 Linux 下面挂载，耍好之后重新拆开，然后看看能不能刷上去，结果并好的包在 Linux 上死活不能挂载，虽然 file 命令显示它就是一个正常的，可以挂载的 img 。<br />
<br />
那就另寻捷径了，上网一搜发现了一款叫 <a target="_blank" href="http://www.romzhushou.com/">ROM助手</a> 的软件，说是能直接修改 img 文件，虽说看里面的功能有点内置程序赚钱的感觉，但是能抓到耗子的猫就是好猫吧，拿来试试再说。<br />
<br />
ROM助手 自带 img 合并拆分，那就先合并掉，然后用自带的编辑功能编辑一下合并好的 img ，把所有多余的内置删掉，然后再把 SuperSU 相关的文件全部放进去，再重新拆开。。。这些步骤都很简单，这里就不多说了<del>（我说了这篇文章一点技术含量都没有的）</del>。<br />
<br />
然后就用分解好的 img 文件以及输出的 rawprogram_unsparse.xml 把之前刷机文件夹里的文件覆盖掉，再用 MiFlash 刷一次机。开机，root 就已经搞定了！<br />
<br />
另外发现这货在 fastboot 模式下面进行 fastboot flash 的时候是不做检查的，能做什么就不知道了，或许以后可以编译个 recovery 放进去吧，这样刷机过程可能就正常一些了。。。</p>

    <link href="http://www.caoyue.com.cn/blog/2015/07/29/wo-yao-rang-wo-de-email-xiang-octopress-yi-yang-piao-liang/"/>

    <id>http://www.caoyue.com.cn/blog/2015/07/29/wo-yao-rang-wo-de-email-xiang-octopress-yi-yang-piao-liang</id>
    <content type="html"><![CDATA[<p>自定义信纸，让 Email 像 Octopress 一样！<br />
<br />
这个想法在我的脑子里一闪而过，<del>但是就像马云说的，梦想还是要有的，如果实现了呢？</del><br />
<br />
那就来实现一下吧！<br /></p>

<!--more-->


<p><br />
首先，把 Octopress 的主页抠出来。。。<br />
删掉所有脚本、博客内容，把背景之类的简化一下，在尾注上加上 Email 专用版标志。。。<br />
然后最终我们就得到了这样一个丑陋东西。。。<br />
<img src="http://www.caoyue.com.cn/images/blog/20150729/blog-email01.jpg" width=533 high=287 /><br />
<del>然后把这些HTML代码复制到邮件里去就可以了！</del><br />
然而现实永远没有那么简单，绝对不要高估 Email 对 HTML 代码的支持能力！<br />
<br />
那怎么办，似乎还是要用图片来解决了。。。<br />
<br />
把这个方框截成图片，把脚注分开截（这样要延长的话就会方便一些），再把空白的地方截下来，延长时比较方便，就像这样<br />
（当时一脑残截成了三个部分，后来一想确实不应该这样）<br />
<img src="http://www.caoyue.com.cn/images/email/email-head.jpg" width=520 high=25 /><br />
<img src="http://www.caoyue.com.cn/images/email/email-main.jpg" width=520 high=205 /><br />
<img src="http://www.caoyue.com.cn/images/email/email-foot.jpg" width=520 high=27 /><br />
最后还有一张方便随时延长：<br />
<img src="http://www.caoyue.com.cn/images/email/email-add.jpg" width=520 high=62 /><br />
<br />
然后，到QQ邮箱里，打开写信模式，把图片上的链接用&#60;map&#62;标签加上去，然后加上各种样式(简写样式自动展开好评)，另外还得一步一步地查看效果以保证样式不会被服务器吞掉。<br />
最后，代码变成了这个样子：（QQ邮箱把所有标签都弄成大写简直差评！）<br /></p>

<p>这是中国特色版的，以后还会有其他语言版本的应该。<br />
最终效果在 QQ邮箱 和 网易邮箱表现还不错（当然要开显示图片）。。。<br />
<del>（除了加载慢出翔以外）</del><br />

美中不足的是：由于用的样式比较复杂，十分符合垃圾邮件的特征，于是。。。<br />
另外，对手机的支持也是一个问题。。。<br />
<br />

    <content type="html"><![CDATA[<p>为了打发暑假时间，<del>顺便唤醒一下一年没动过的编程思维</del>，在TI-Nspire上写了个字符串库啊。。。<br />
本来是想做一个TI-Nspire上的线性输入程序，结果发现要用到很多这种函数，于是就干脆写了个lib，至于线性输入。。。那就再(qi)说(keng)吧！<br />
想来想去就想到了18个函数，涵盖一般的增加,删除,分开,组合,计数&hellip;以及为表达式字符串<del>专门设计</del>的括号检查,空格检查<del>（虽然都很坑）</del><br />
为什么叫 strlib2 呢？因为貌似以前有个大神 Eagle-man 写过一个 strlib 了，<del>我这种业余的自然只能屈居 strlib2 了啊啊啊</del>。。。<br />
这个项目已经放到github上了，<a href=https://github.com/haruue/strlib2.tns.git>欢迎到项目主页看看吧</a><del>（什么？这卵东西还配上github？）</del></p>

    <content type="html"><![CDATA[<p>Hello World!<br />
此乃开博第一文也！<br />
折腾了一整天，终于在 Openshift 上<del>（本来就不是让你放在这里的）</del>开了这个 Octopress 。人家本来说的就是“A blogging framework for hackers”，看来自己距离 hacker 的那种级别还有相当遥远的距离。<br />
忙活了一整年，在不得消停的压力中熬完高三，在艰险与激情中搞定高考，然后就是在忐忑不安中知晓成绩，挑选专业和大学。。。<br />
终于，我获得了大约 2 个月的时间可以做自己想做的事，研究自己喜欢的东西。<br />
似乎，忽然间就自由了呢。。。<br />
规划了一年多的计划终于可以付诸行动，这个 Blog ，当然也是其中之一。<br />
未来又会是怎么样的？可能答案就会出现在以后的文字中吧！<br />
最后感谢<span style=" font-weight:bold;"><a href="http://www.uiharu.space/">初春静流</a></span>，正是他美丽的花园 ，把我吸引到了 Octopress 这片神奇的土地。<br />
