//获取微信公从号access_token

}
$wx = array();
//生成签名的时间戳
$wx['timestamp'] = time();
//生成签名的随机串
$wx['noncestr'] = 'Wm3WZYTPz0wzccnW';
//jsapi_ticket是公众号用于调用微信JS接口的临时票据.正常情况下,jsapi_ticket的有效期为7200秒,通过access_token来获取.
$wx['jsapi_ticket'] = wx_get_jsapi_ticket();
//分享的地址,注意：这里是指当前网页的URL,不包含#及其后面部分,曾经的我就在这里被坑了,所以小伙伴们要小心了
$wx['url'] = 'http://www.baidu.com';
$string = sprintf("jsapi_ticket=%s&noncestr=%s&timestamp=%s&url=%s",$wx['jsapi_ticket'],$wx['noncestr'],$wx['timestamp'],$wx['url']);
//生成签名
$wx['signature'] = sha1($string);
/*
注意事项
签名用的noncestr和timestamp必须与wx.config中的nonceStr和timestamp相同.
签名用的url必须是调用JS接口页面的完整URL.
出于安全考虑,开发者必须在服务器端实现签名的逻辑.
