<h3>web.py学习笔记</h3>
<p>由于后台的几个需求，需要给测试同学构造gm指令以方便测试，思来想去还是搭建个快速的webserver来方便测试同学，django太庞大，tornado不大熟悉，别人介绍了下<a href="http://webpy.org/">web.py</a>，而且也不需要安装一大堆的第三方依赖库(原谅楼主有时候在服务器上不喜欢装第三方库的臭毛病吧)，甚至把web.py打包后都不需要额外安装任何东西。简单看了下web.py的文档，感觉还是入手还是比较容易。</p>
<p>工程文档目录结构：</p>
<pre class="code literal-block">main
|---- conf (工程配置文件)
|---- static (js，图片等)
|---- template (html文件)
|---- web (web.py的库文件)
|---- config.py (目录，密码等配置)
|---- index.py (路由文件)
</pre>
<p>接着就可以开始coding，在web.py中需要指定url路由,当url请求中包含相应关键字时则跳转到相应的class中进行处理。</p>
<pre class="code literal-block"><span class="n">urls</span> <span class="o">=</span> <span class="p">(</span>
<span class="s">'/favicon.ico'</span><span class="p">,</span><span class="s">"Ico"</span><span class="p">,</span>
<span class="s">'/about'</span><span class="p">,</span> <span class="s">"About"</span><span class="p">,</span>
<span class="s">'/list_(.*)'</span><span class="p">,</span> <span class="s">"Script"</span><span class="p">,</span>
<span class="s">'/bin_upload(.*)'</span><span class="p">,</span> <span class="s">"Upload"</span><span class="p">,</span>
<span class="s">'/changetime(.*)'</span><span class="p">,</span> <span class="s">"ChangeTime"</span><span class="p">,</span>
<span class="s">'/(.*)'</span><span class="p">,</span><span class="s">'Index'</span><span class="p">,</span>
<span class="p">)</span>
<span class="n">render</span> <span class="o">=</span> <span class="n">web</span><span class="o">.</span><span class="n">template</span><span class="o">.</span><span class="n">render</span><span class="p">(</span><span class="s">'template/'</span><span class="p">)</span>
</pre>
<p>以下以about跳转为例：</p>
<pre class="code literal-block"><span class="k">class</span> <span class="nc">Upload</span><span class="p">:</span>
<span class="k">def</span> <span class="nf">POST</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="o">*</span><span class="n">args</span><span class="p">,</span> <span class="o">**</span><span class="n">kw</span><span class="p">):</span>
<span class="c"># save a file to disk</span>
<span class="n">x</span> <span class="o">=</span> <span class="n">web</span><span class="o">.</span><span class="n">input</span><span class="p">(</span><span class="nb">file</span><span class="o">=</span><span class="p">{})</span>
<span class="c">#print "bintag, filename:", x.bintag, x.file.filename</span>
<span class="k">if</span> <span class="n">x</span><span class="o">.</span><span class="n">bintag</span> <span class="o">==</span> <span class="s">""</span> <span class="ow">or</span> <span class="n">x</span><span class="o">.</span><span class="n">file</span><span class="o">.</span><span class="n">filename</span> <span class="o">==</span> <span class="s">""</span><span class="p">:</span>

<span class="c"><!--<div id="filedrag">or drop the file here</div>--></span>
<span class="nt"></div></span>
<span class="nt"></fieldset></span>
<span class="nt"></form></span>
</pre>
<p>当POST请求跳转到bin_upload时，则跳转到Upload进行相应的处理，Upload中处理接收的参数，进行后台逻辑处理。如果需要将处理后的数据返回前台，通常使用render来处理返回的数据<code>render.htmlfilename(parms)</code>的方式。</p>
