<span style="font-size:18px;">网站上的商城可以搭建ecshop实现，微信端的微商城也可以开发wap版商城，然后通过链接链到微信菜单上，这样实现起来就不需要远程调用数据了，但登陆上有个问题，在微信上进入微商城在用户体验上当然不需要再登陆只需要有微信openid即可。所以有个考虑是在微信端开发微商城，所以的数据是取自网站商城的，这时需要远程请求数据。 有了ihttp_request()方法后，可通过此方法获取远程数据</span>

打印的内容非常详细，连头部信息都打出来了，但我们只需要关心content中的内容，这才是我们需要获取的数据
["content"]=>
string(241) "{"result":"success","msg":"","info":{"data_info":[{"goods_id":"1","last_modify":"1423937979"},{"goods_id":"2","last_modify":"1425595831"},{"goods_id":"3","last_modify":"1423937959"},{"goods_id":"4","last_modify":"1423942862"}],"counts":"4"}}"
