html5网页链接分享到微信朋友，微信朋友圈，QQ，微博带图标和摘要
步骤一：
登录微信公众平台：https://mp.weixin.qq.com/
获取到appid，添加IP白名单（添加服务IP即可）
步骤二：绑定域名
先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。
步骤三：引入JS文件
获取JS地址：https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/JS-SDK.html#3
在设置开发--->接口权限 查看是否已经获取到分享权限（需要验证公众号）

}除此之外要创建一个文件夹jsoncache，在文件夹中放三个文件，后两个文件用在jssdk.php代码之中用于存储值使用，
第一个文件内容为deny from all（apache 安全性设置），如果你是nginx就需要重新设置
<?php
require_once './jssdk.php';
$jssdk = new JSSDK('appid', 'appsecret');
$wxconfig = $jssdk->getSignPackage();
?>
<script type="text/javascript" src="http://res.wx.qq.com/open/js/jweixin-1.6.0.js"></script>
<script>
if(isMobile()){
wx.config({
debug: false,
appId: '<?php echo $wxconfig['appId']; ?>',
timestamp: <?php echo $wxconfig["timestamp"]; ?>,
nonceStr: '<?php echo $wxconfig["nonceStr"]; ?>',
signature: '<?php echo $wxconfig["signature"]; ?>',
jsApiList: [
'onMenuShareTimeline',
'onMenuShareAppMessage',
'onMenuShareQQ',
'onMenuShareWeibo'
'updateAppMessageShareData'
]
});
wx.ready(function() {
var shareTitle = '标题';
var shareDesc = '描述';
var shareLink = '地址';
var shareImg = 'logo版';
wx.updateAppMessageShareData({
title: shareTitle,
desc: shareDesc,
link: shareLink,
imgUrl: shareImg,
success: function () {
// 设置成功
}
});
// 分享给朋友事件绑定
wx.onMenuShareAppMessage({
title: shareTitle,
desc: shareDesc,
link: shareLink,
imgUrl: shareImg
});
// 分享到朋友圈
wx.onMenuShareTimeline({
title: shareTitle,
link: shareLink,
imgUrl: shareImg
});
// 分享到QQ
wx.onMenuShareQQ({

});
// 分享到微博
wx.onMenuShareWeibo({

}
