原文：http://jingyan.baidu.com/article/d3b74d64c517051f77e609ed.html为了净化网络，整顿诱导分享及诱导关注行为，微信于2014年12月30日发布了《微信公众平台关于整顿诱导分享及诱导关注行为的公告》，微信平台开发者发现，原有的微信分享功能不能用了，在iphone手机上，显示为当前页的链接，之前设置的图标和标题等都没有了。虽然在部分android手机上还可以用，但最近微信升级后，分享功能也不正常了。正在苦于微信分享该怎么解决时，微信于2015年1月10日即时发布了开放JS-SDK，为微信网站的开发提供了强大的js功能。这里仅就分享功能的使用进行一些描述。下面的代码，服务器端使用的是php。<h2 class="exp-content-head" style="margin: 40px 0px 0px;
