php监控apple store是否有货【2014-09-15】（服务器端）
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http://store.apple.com/hk-zh/buy-iphone/iphone6/ 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"http://store.apple.com/hk-zh/buyFlowSelectionSummary/IPHONE6P?node=home/shop_iphone/family/iphone6&step=select&option.dimensionScreensize=5_5inch&option.dimensionColor=gold&option.dimensionCapacity=128gb&option.carrierModel=UNLOCKED%2FWW&carrierPolicyType=UNLOCKED" 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":"<img src=http://www.mamicode.com/"http://store.storeimages.cdn-apple.com/7872/as-images.apple.com/is/image/AppleInc/aos/published/images/i/ph/iphone6p/gold/iphone6p-gold-select-2014_GEO_HK_LANG_ZH?wid=110&hei=78&fmt=jpeg&qlt=95&op_sharpen=0&resMode=bicub&op_usm=0.5,1.5,0,0&iccEmbed=0&layer=comp&.v=1410265171755\" alt=\"\" width=\"110\" height=\"78\" data-scale-params-2=\"wid=220&hei=156&fmt=jpeg&qlt=95&op_sharpen=0&resMode=bicub&op_usm=0.5,1.5,0,0&iccEmbed=0&layer=comp&.v=1410265171755\" itemprop=\"image\"/>",
"productTitle":"iPhone 6 Plus 128GB 金色 已解鎖",
"purchaseOptions":{"financing":"\n\n\n\n\n\n",
"promotions":"\n\n<span class=\"gift-card\">\n\n</span>\n",
"shippingPrice":"\n<span class=\"freeshipping promo-text\">免費運送</span>",
"shippingLead":"\n預計出貨時間<b>:</b><br/>\n<span class=\"customer_commit_display\">暫時無法提供</span>\n\n",
"price":"\n<span class=\"current_price\">\n<span itemscope=\"itemscope\" itemprop=\"offers\" itemtype=\"http://schema.org/Offer\">\n\n<meta itemprop=\"priceCurrency\" content=\"HKD\"/>\n<span itemprop=\"price\">\nHK$8,088\n</span>\n</span>\n</span>\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：
