微信JSSDK分享功能详解
本文以微信分享到朋友圈,分享给微信好友为例为参考,进行调用测试,想添加其他的功能,自行查看开发人员文档即可
工欲善其事,必先利其器,好好利用下边的帮助工具,都是腾讯给开发人员的工具

微信版本6.0以后,原有的WeixinJSBridge.on('menu:share:timeline', function (argv) {}不再可在以使用,那如何在使用微信的其他功能呢?官方给出了JSSDK的使用,帮助我们解决~
前言:
虽然微信提供了JSSDK,但是这不意味着你可以用自定义的按钮来直接打开微信的分享界面,这套JSSDK只是把微信分享接口的内容定义好了,实际还是需要用户点击右上角的菜单按钮进行主动的分享,用户点开分享界面之后,出现的内容就会是你定义的分享标题、图片和链接。
- 1.JSSDK使用步骤
- 1.1.1 步骤一:绑定域名
- 1.1.2 步骤二:引入JS文件
- 1.1.3 步骤三:通过config接口注入权限验证配置
($tpl['appid'] $tpl['appsercret']换成你自己!)
- 1.1.4 步骤四:通过ready接口处理成功验证
- 1.1.5 步骤五:通过error接口处理失败验证
- 2.实测图解:

2.2分享到朋友圈:
2.3分享到朋友圈:
2.3调试界面:
- 3.实测代码样例:
后台代码(jssdk.PHP见后边):
- //获取apptoken
- require_once "jssdk.php";
- $jssdk = new JSSDK($appid,$appsecret);//这里填写自己的appid 和secret
- $signPackage = $jssdk->GetSignPackage();
- $this->assign("signPackage",$signPackage);
JS配置代码
- <script type="text/javascript" src='http://res.wx.qq.com/open/js/jweixin-1.0.0.js'></script>
- <script type="text/javascript">
- wx.config({
- debug: false,
- appId: '{$signPackage["appId"]}',
- timestamp: '{$signPackage["timestamp"]}',
- nonceStr: '{$signPackage["nonceStr"]}',
- signature: '{$signPackage["signature"]}',
- jsApiList: [
- // 所有要调用的 API 都要加到这个列表中
- 'checkJsApi',
- 'onMenuShareTimeline',
- 'onMenuShareAppMessage',
- 'onMenuShareQQ',
- 'onMenuShareWeibo',
- 'onMenuShareQZone'
- ]
- });
- </script>
- <script type="text/javascript" src='http://203.195.235.76/jssdk/js/zepto.min.js'></script>
JS分享代码:
- <script type="text/javascript">
- //完成wx.config,执行这里
- wx.ready(function () {
- //分享到朋友圈
- wx.onMenuShareTimeline({
- title: '1111111', // 分享标题
- link:window.location.href,
- imgUrl: "{pigcms:$res['pic']}", // 分享图标
- success: function () {
- // 分享成功执行此回调函数
- alert('success');
- },
- cancel: function () {
- alert('cancel');
- }
- });
- //分享给朋友
- wx.onMenuShareAppMessage({
- title: '22222', // 分享标题
- desc: '22222',
- link:window.location.href,
- imgUrl: "{pigcms:$res['pic']}", // 分享图标
- trigger: function (res) {
- // 不要尝试在trigger中使用ajax异步请求修改本次分享的内容,因为客户端分享操作是一个同步操作,这时候使用ajax的回包会还没有返回
- },
- success: function (res) {
- // 分享成功执行此回调函数
- alert('已分享');
- },
- cancel: function (res) {
- alert('已取消');
- },
- fail: function (res) {
- alert(JSON.stringify(res));
- }
- });
- });
- </script>
