进入“安全中心”里设置“IP白名单”，一个IP放一行。

步骤二：实现微信自定义分享

sample.php 示例代码

<?phprequire_once "jssdk.php";$jssdk = new JSSDK("yourAppID", "yourAppSecret");$signPackage = $jssdk->GetSignPackage();?><!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title></title></head><body><script src="//res./open/js/jweixin-1.6.0.js"></script><script>var title='标题';var description='描述';var link='链接地址';var imgUrl = '图标';wx.config({debug: false,appId: '<?php echo $signPackage["appId"];?>',timestamp: <?php echo $signPackage["timestamp"];?>,nonceStr: '<?php echo $signPackage["nonceStr"];?>',signature: '<?php echo $signPackage["signature"];?>',jsApiList: ['onMenuShareAppMessage','onMenuShareTimeline']});wx.ready(function () {//获取“分享给朋友”按钮点击状态，点击后发送给朋友微信，微信上的推送显示内容就是下面的数据wx.onMenuShareAppMessage({title: title, // 分享标题desc: description, // 分享描述link: link, // 分享链接，该链接域名或路径必须与当前页面对应的公众号JS安全域名一致imgUrl: imgUrl, // 分享图标type: '', // 分享类型,music、video或link，不填默认为linkdataUrl: '', // 如果type是music或video，则要提供数据链接，默认为空success: function () {console.log('分享成功');},cancel: function () {console.log('分享失败');}});//分享到朋友圈wx.onMenuShareTimeline({title: title, // 分享标题desc: description, // 分享描述link: link, // 分享链接，该链接域名或路径必须与当前页面对应的公众号JS安全域名一致imgUrl: imgUrl, // 分享图标success: function () {console.log('分享成功');},cancel: function () {console.log('分享失败');}});});</script> </body></html>

jsapi_ticket.php 用于存储jsapi_ticket

<?php exit();?>{"jsapi_ticket":"","expire_time":0}

access_token.php 用于存储access_token

<?php exit();?>{"access_token":"","expire_time":0}
