一年一度的苹果新品刚发布后的几天，9月12号就正式上市了，按照惯例，果农们又得在网上拼个你死我活了，香港苹果店在12号下午3点后正式开放购买，还没来得及写好脚本，经过不断的按F5和enter，不懈努力之下，抢到了1台!

抢收过后，特意写下这个脚本，监控苹果网上商店是否有货，有货第一时间发出邮件通知我，网上有类似的订阅服务，留个邮件地址也能收到相关的提醒，也有chrom或者firefox的插件能够在浏览器定时监控，有货第一时间发出窗口通知或者播放警告声。

此类服务的原理大多使用同一原理，就是发送get请求，获取苹果服务器的回应json字符串，判断里面的值,比如这次有isBuyable:true/false.获取方法有很多，比如我这次写的php，运行在服务器端，也能用javascript写，在浏览器定时运行，也能做成浏览器插件，接收来自服务器的返回信息并根据对应的回应进行相关的触发提醒。

至于怎么获取或者怎么知道苹果服务器的get url，有开发经验的童鞋肯定用过firefox 的firebug, 打开购买的网页后，打开firebug，然后按照正常购买的流程，比如选择"iphone 6 plus"->"金色"->"64GB",留意这些选项都选中之后，在firebug的网络模块里可以看到浏览器发出了" 这样的请求，然后打开该请求的响应信息，内容很长，基本如下：

{"head":{"status":"200","data":{}}, "body":{"content":{"pageURL":"5.5-吋螢幕-128gb-金色-已解鎖", "selected":{"productImage":"
     
      ", "productTitle":"iPhone 6 Plus 128GB 金色 已解鎖", "purchaseOptions":{"financing":"\n\n\n\n\n\n",                   "promotions":"\n\n
      
       \n\n\n",                   "shippingPrice":"\n
       
        免費運送",                   "shippingLead":"\n預計出貨時間
        :
        
\n
        
         暫時無法提供\n\n",                   "price":"\n
         
          \n
          
           \n\n
           \n
           
            \nHK$8,088\n\n\n\n\n\n",                   "isBuyable":false}, "partNumber":"MGAF2ZP/A"}, "pageTitle":"iPhone 6 Plus 128GB 金色 已解鎖 - Apple Store (香港)"}}}

返回的json里面，包含了isBuyable的参数，估计苹果就是利用这个响应来判断是否有存货，并且来控制页面的操作。

知道这个原理后，就可以着手写脚本了，主要是用curl的api来发送请求，将返回的json转换为array，并判断该字段的值，false为无货，true为有货，代码已完成，摘录如下：


     array('screensize'=>'4_7inch','color'=>'silver','capacity'=>'16gb'),                1=>array('screensize'=>'4_7inch','color'=>'space_gray','capacity'=>'16gb'),                2=>array('screensize'=>'4_7inch','color'=>'gold','capacity'=>'16gb'),                3=>array('screensize'=>'4_7inch','color'=>'silver','capacity'=>'64gb'),                4=>array('screensize'=>'4_7inch','color'=>'space_gray','capacity'=>'64gb'),                5=>array('screensize'=>'4_7inch','color'=>'gold','capacity'=>'64gb'),                6=>array('screensize'=>'4_7inch','color'=>'silver','capacity'=>'128gb'),                7=>array('screensize'=>'4_7inch','color'=>'space_gray','capacity'=>'128gb'),                8=>array('screensize'=>'4_7inch','color'=>'gold','capacity'=>'128gb'),                );$iphone6plus=array(                0=>array('screensize'=>'5_5inch','color'=>'silver','capacity'=>'16gb'),                1=>array('screensize'=>'5_5inch','color'=>'space_gray','capacity'=>'16gb'),                2=>array('screensize'=>'5_5inch','color'=>'gold','capacity'=>'16gb'),                3=>array('screensize'=>'5_5inch','color'=>'silver','capacity'=>'64gb'),                4=>array('screensize'=>'5_5inch','color'=>'space_gray','capacity'=>'64gb'),                5=>array('screensize'=>'5_5inch','color'=>'gold','capacity'=>'64gb'),                6=>array('screensize'=>'5_5inch','color'=>'silver','capacity'=>'128gb'),                7=>array('screensize'=>'5_5inch','color'=>'space_gray','capacity'=>'128gb'),                8=>array('screensize'=>'5_5inch','color'=>'gold','capacity'=>'128gb'),                );// iphone 6 foreach ($iphone6 as $model){    $screensize=$model['screensize'];    $color=$model['color'];    $capacity=$model['capacity'];    $json_url="http://store.apple.com/hk/buyFlowSelectionSummary/IPHONE6?node=home/shop_iphone/family/iphone6&step=select&option.dimensionScreensize=".$screensize."&option.dimensionColor=".$color."&option.dimensionCapacity=".$capacity."&option.carrierModel=UNLOCKED%2FWW&carrierPolicyType=UNLOCKED";    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $json_url);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);//伪装成浏览器    $str=curl_exec($ch);    $str_array=json_decode($str,true);    curl_close($ch);    $available=$str_array['body']['content']['selected']['purchaseOptions']['isBuyable'];    $partnumber=$str_array['body']['content']['selected']['partNumber'];    if ($available!==false)        {            echo $screensize."-".$color."-".$capacity.": is available, please go to http://store.apple.com/hk-zh/buy-iphone/iphone6?cppart=UNLOCKED/WW&product=".$partnumber."&step=accessories"."\n";            $iphone6msg.="".$screensize." ".$color." ".$capacity." is available,

至于该监控是否准确，有待验证，只能坐等苹果有好消息了，希望延迟不会超过10分钟（假如邮件能够正常发送成功的话）。
