			<content:encoded><![CDATA[<p>The legendary rock&#8217;n'roll band <a href="http://acdc.com/">AC/DC</a> will land on brazilian soil for the second time in November, for what is considered to be the show of the decade around here! The tickets for their single concert, sold by the <a href="http://www.ticketmaster.com.br/">brazilian Ticketmaster</a>, ran out in less than 48 hours. This concert is going to be amazing!</p>
<p>A lot of things happened during those 48 hous. The Ticketmaster staff had trouble to keep the website on-line, and due to the enormous load, it&#8217;s possible that only a few thousands of people had enough luck to buy their tickets via the website.</p>
<p>Also, Ticketmaster admits that the notification e-mails may not reach, which means we cannot rely on those to follow our orders. In fact, they recomend that customers check their orders manually once a day. Oh boy&#8230;</p>
<p>I hate to do certain tasks manually, specially the ones that can be automated. So, in this post I&#8217;ll show you a very simple <a href="http://www.python.org">Python</a>-based command-line tool that displays the status of your Ticketmaster<sup class='footnote'><a href='#fn-760-1' id='fnref-760-1'>1</a></sup> orders on the screen<sup class='footnote'><a href='#fn-760-2' id='fnref-760-2'>2</a></sup>, using a technique known as <a href="http://en.wikipedia.org/wiki/Web_scraping">web scraping</a>.</p>

    main<span style="color: black;">&#40;</span><span style="color: black;">&#41;</span></pre></div></div>

<p>The reason I&#8217;ve used web scrapping is because the brazilian Ticketmaster doesn&#8217;t seem to provide an API the way <a href="http://flickr.com">Flickr</a> does, for example. Nevertheless, the code is quite simple.</p>
<p>As you can see, it first fires a HTTP request to the login URI in order to validate the user credentials. If the authentication succeeds, our cookie-aware <code>opener</code> will get the session cookies from the server and use them on the following requests, which extract the current order status for each order ID.</p>
<p>Now, let&#8217;s give it a spin:</p>
<div id="attachment_763" class="wp-caption aligncenter" style="width: 310px"><a href="http://weblog.destaquenet.com/wp-content/uploads/2009/10/order_status1.png"><img src="http://weblog.destaquenet.com/wp-content/uploads/2009/10/order_status1-300x104.png" alt="Current order status" title="order_status" width="300" height="104" class="size-medium wp-image-763" /></a><p class="wp-caption-text">Current order status</p></div>
<p>Finally, add a new entry to your <code>crontab</code> to run the script whenever you want (e.g. every 10 minutes):</p>
<pre>*/10 * * * * python ticketmaster_order_status.py --email=your@email.com --password=passwd --order-ids=1234</pre>
<p>Good luck and let there be rock! <img src='http://weblog.destaquenet.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>
<div class='footnotes'>
<div class='footnotedivider'></div>

<li id='fn-760-1'>The script only works for the <a href="http://www.ticketmaster.com.br/">brazilian Ticketmaster</a> website. <span class='footnotereverse'><a href='#fnref-760-1'>&#8617;</a></span></li>

			<content:encoded><![CDATA[<p>A legendária banda de rock&#8217;n'roll <a href="http://acdc.com/">AC/DC</a> irá pousar em solo brasileiro pela segunda vez em Novembro, para o que é considerado o show da década por aqui! Os ingressos para a única apresentação, vendidos pela <a href="http://www.ticketmaster.com.br/">Ticketmaster</a>, se esgotaram em menos de 48 horas. Esse show será incrível!</p>
<p>Muita coisa aconteceu nessas 48 horas. O pessoal da Ticketmaster teve trabalho para manter o website no ar e, em razão da enorme carga, é possível que apenas poucos milhares de fãs tenham sido sortudos o bastante para comprar seus ingressos através da internet.</p>
<p>Além disso, a Ticketmaster admite que os e-mails de notificação podem não ser enviados, o que significa que não podemos depender deles para acompanhar nossos pedidos. Na verdade, eles até recomendam que seus clientes chequem os pedidos diariamente, na mão. Caramba&#8230;</p>
<p>Eu odeio fazer certas tarefas manualmente, especialmente as que podem ser automatizadas. Então, neste post eu mostrarei uma ferramenta escrita em <a href="http://www.python.org">Python</a> que mostra a situação dos seus pedidos Ticketmaster na tela<sup class='footnote'><a href='#fn-710-1' id='fnref-710-1'>1</a></sup>, usando uma técnica conhecida como <a href="http://en.wikipedia.org/wiki/Web_scraping">web scraping</a>.</p>

<p>A razão pela qual eu optei por web scrapping é porque a Ticketmaster não fornece uma API da mesma forma que o <a href="http://flickr.com">Flickr</a> fornece, por exemplo. Ainda assim, o código é bastante simples.</p>
<p>Como você pode ver, ele primeiro envia uma requisição HTTP para a URI de login com o objetivo de validar as credenciais do usuário. Se a autenticação for bem sucedida, nosso <code>opener</code> receberá os cookies de sessão do servidor e os usará nas requisições seguintes, que buscam a situação de cada um dos pedidos informados.</p>
<p>Rodando o script agora:</p>
<div id="attachment_763" class="wp-caption aligncenter" style="width: 310px"><a href="http://weblog.destaquenet.com/wp-content/uploads/2009/10/order_status1.png"><img src="http://weblog.destaquenet.com/wp-content/uploads/2009/10/order_status1-300x104.png" alt="Current order status" title="order_status" width="300" height="104" class="size-medium wp-image-763" /></a><p class="wp-caption-text">Current order status</p></div>
<p>Finalmente, inclua uma nova entrada no seu <code>crontab</code> para que o script rode sempre que necessário (ex: a cada 10 minutos):</p>
<pre>*/10 * * * * python ticketmaster_order_status.py --email=seu@email.com --password=senha --order-ids=1234</pre>
<p>Boa sorte e <em>let there be rock</em>! <img src='http://weblog.destaquenet.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>
<div class='footnotes'>
<div class='footnotedivider'></div>
<ol>
<li id='fn-710-1'>O script usa a biblioteca <a href="http://www.galago-project.org/news/index.php">libnotify</a> para mostrar as notificações na tela, portanto não esqueça de instalá-la. <span class='footnotereverse'><a href='#fnref-710-1'>&#8617;</a></span></li>

			<content:encoded><![CDATA[<p>Todos já devem estar sabendo, mas vale a pena repetir que irá rolar em Sampa, nos dias 15 e 16 de Outubro, o evento <a href="http://www.locaweb.com.br/railssummit/">Rails Summit Latin America</a>.</p>
<p>Minha expectativa em relação a este evento em particular é muito boa. Apesar de já terem ocorrido outros eventos dedicados ao <a href="http://rubyonrails.org/">Ruby on Rails</a> aqui no Brasil, os organizadores desse evento em particular resolveram levar a coisa toda a um outro nível.</p>
<p>Citando o site do evento:</p>
<blockquote><p>
O Rails Summit Latin America surge para completar a agenda dos grandes eventos mundiais de Ruby on Rails™. Inspirado na RailsConf americana que reúne cerca de 2.000 desenvolvedores e tomadores de decisão, o Rails Summit Latin America trará os principais palestrantes e especialistas no assunto do mundo inteiro incluindo participação especial do criador do Ruby on Rails™, David Hansson.</p>
<p>Com diversos palestrantes internacionais e empreendedores brasileiros, o evento será referência sobre o assunto na América Latina, trazendo o que há de melhor na plataforma para o Brasil.
</p></blockquote>
<p>Para quem não se inscreveu, corra que ainda dá tempo. (eu acho!) <img src='http://weblog.destaquenet.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>Nos vemos por lá!</p>
