thinkphp与微信JSSDK结合分享实例
新建CommonController.class.php来获取
appId: '', // 必填，公众号的唯一标识
timestamp: , // 必填，生成签名的时间戳
nonceStr: '', // 必填，生成签名的随机串
signature: '',// 必填，签名<?php <br />
namespace Home\Controller;<br>

}<br>
}下面就可以使用了
新建IndexController.class.php<?php <br />
namespace Home\Controller;<br>
use Think\Controller;<br>
<br>
class IndexController extends CommonController {<br>
public function index(){ <br>
$this->display();<br>
}<br>
<br>
}html文件中添加<script></script><br>
<script><br />
wx.config({<br />
appId: '{$signPackage.appId}',<br />
timestamp: {$signPackage.timestamp},<br />
nonceStr: '{$signPackage.nonceStr}',<br />
signature: '{$signPackage.signature}',<br />
jsApiList: [<br />
'checkJsApi',<br />
'onMenuShareTimeline',<br />
'onMenuShareAppMessage',<br />
'onMenuShareQQ',<br />
'onMenuShareWeibo'<br />
]<br />
}); <br />
wx.ready(function () {<br />
// 1 判断当前版本是否支持指定 JS 接口，支持批量判断<br />
wx.checkJsApi({<br />
jsApiList: [<br />
'getNetworkType',<br />
'previewImage',<br />
'onMenuShareTimeline',<br />
'onMenuShareAppMessage',<br />
'onMenuShareQQ',<br />
'onMenuShareWeibo'<br />
], <br />
});<br />
<br />
var shareData = {<br />
//标题<br />
title: '标题',<br />
//摘要<br />
desc: '摘要',<br />
//链接,可以换主页<br />
link: '{$signPackage.url}',<br />
//缩略图<br />
imgUrl: '缩略图', <br />
<br />
};<br />
wx.onMenuShareAppMessage(shareData);<br />
wx.onMenuShareTimeline(shareData);<br />
wx.onMenuShareQQ(shareData);<br />
wx.onMenuShareWeibo(shareData);<br />
});<br />
</script>之后就大功告成
