微信公眾號(hào)自定義分享內(nèi)容實(shí)現(xiàn)
Jun 08, 2016 pm 05:20 PM微信公眾號(hào)號(hào)在手機(jī)中通過(guò)api接口可以實(shí)現(xiàn)自定義分享內(nèi)容了,下面我們來(lái)看這個(gè)接口的實(shí)現(xiàn)步驟。
一、準(zhǔn)備階段
公眾號(hào)一個(gè),微網(wǎng)站一個(gè)。
?
二、綁定域名
先登錄微信公眾平臺(tái)進(jìn)入“公眾號(hào)設(shè)置”的“功能設(shè)置”里填寫(xiě)“JS接口安全域名”。

四、視圖顯示
在需要調(diào)用JS接口的頁(yè)面引入如下JS文件,(支持https):http://res.wx.qq.com/open/js/jweixin-1.0.0.js
通過(guò)config接口注入權(quán)限驗(yàn)證配置
<script> //通過(guò)config接口注入權(quán)限驗(yàn)證配置 wx.config({ debug : false, appId : 'AppID', timestamp : '<?php echo $wx["timestamp"];?>', nonceStr : '<?php echo $wx["noncestr"];?>', signature : '<?php echo $wx["signature"];?>', jsApiList : ['onMenuShareTimeline', 'onMenuShareAppMessage', 'onMenuShareQQ', 'onMenuShareWeibo'] }); wx.ready(function(){ var s_title = '分享標(biāo)題', // 分享標(biāo)題 s_link = '分享鏈接', // 分享鏈接 s_desc = '分享描述', //分享描述 s_imgUrl = '分享圖片'; // 分享圖標(biāo) //朋友圈 wx.onMenuShareTimeline({ title: s_title, // 分享標(biāo)題 link: s_link, // 分享鏈接 imgUrl: s_imgUrl, // 分享圖標(biāo) success: function () { }, cancel: function () { } }); //發(fā)送給好友 wx.onMenuShareAppMessage({ title: s_title, // 分享標(biāo)題 desc: s_desc, // 分享描述 link: s_link, // 分享鏈接 imgUrl: s_imgUrl, // 分享圖標(biāo) type: '', // 分享類(lèi)型,music、video或link,不填默認(rèn)為link dataUrl: '', // 如果type是music或video,則要提供數(shù)據(jù)鏈接,默認(rèn)為空 success: function () {}, cancel: function () {} }); //QQ好友 wx.onMenuShareQQ({ title: s_title, // 分享標(biāo)題 desc: s_desc, // 分享描述 link: s_link, // 分享鏈接 imgUrl: s_imgUrl, // 分享圖標(biāo) success: function () { }, cancel: function () { } }); //騰訊微博 wx.onMenuShareWeibo({ title: s_title, // 分享標(biāo)題 desc: s_desc, // 分享描述 link: s_link, // 分享鏈接 imgUrl: s_imgUrl, // 分享圖標(biāo) success: function () { }, cancel: function () { } }); }); </script>
五、大功告成
基本上的流程就是這樣了,比較麻煩的一點(diǎn)就是生成簽名那一塊,注意一點(diǎn)就行了
