java在H5中微信公众号分享

今天研究了一下关于微信公众号里的分享，本来是想要做成下图一样的分享方式。但后来发现H5里根本不支持这种方式。

微信对H5的支持还是挺不友好的，上图中我发现是小程序或APP内可以做到以上的方式。

公众号里虽然有对外的分享接口，但只能做到回调的判断。

我贴一下自己研究的代码，以下代码是H5里做的一些代码的总结。

前端代码：

<input type="hidden" id="title" value="title">
<input type="hidden" id="desc" value="desc">
<input type="hidden" id="imgUrl" value="imgUrl">
<input type="hidden" id="path" value="http://www.shengsenorg.com">

<!--    -->
<script type="text/JavaScript" src="http://res.wx.qq.com/open/js/jweixin-1.6.0.js"></script>
<script>
    function share() {
        var title = $("#title").val();
        var desc = $("#desc").val();
        // var name     = $("#program_name").val();
        var imgUrl = $("#imgUrl").val();
        var path = $("#path").val();
        var url = location.href.split('#')[0];
        // var url = "http://www.shengsenorg.com";
        var signature, timestamp, noncestr, appid;
        /**/
        $.ajax({
            url: "/ajax/weixinshare/getShare",
            type: 'GET',
            data: {
                url: url
            },
            success: function (d) {
                signature = d.data.wxSignature;
                timestamp = d.data.wxTimestamp;
                noncestr = d.data.wxNoncestr;
                appid = d.data.appId;
                wx.config({
                    debug: false, // ,apialertpclogpcappId: appid, // timestamp: timestamp, // nonceStr: noncestr, // signature: signature,// jsApiList: ['checkJsApi', 'onMenuShareAppMessage','onMenuShareTimeline'] // JS// jsApiList: ['checkJsApi', 'onMenuShareTimeline', 'onMenuShareAppMessage', 'updateTimelineShareData', 'updateAppMessageShareData', 'getLocation', 'scanQRCode', 'uploadImage', 'downloadImage', 'showAllNonBaseMenuItem', 'hideAllNonBaseMenuItem'] // JS});
                wx.checkJsApi({
                    jsApiList: ['checkJsApi',
                        'onMenuShareAppMessage',
                        'onMenuShareTimeline'
                    ],
                    success: function (res) {
                        console.log(res)
                        // apitruefalse
                        // {"checkResult":{"chooseImage":true},"errMsg":"checkJsApi:ok"}
                    }
                });
                wx.error(function (res) {
                    alert("error00:" + JSON.stringify(res));
                });
                wx.ready(function () {
                    //wx.onMenuShareAppMessage({
                        title: title, // desc: desc, // link: path, // JSimgUrl: imgUrl, // s
                        type: 'link', // ,musicvideolinklink
                        dataUrl: '', // typemusicvideosuccess: function () {
                            // alert("OK");
                        },
                        cancel: function () {
                            // alert("fail");
                        }
                    });
                    //wx.onMenuShareTimeline({
                        title: title, // link: path, // JSimgUrl: imgUrl, // success: function () {
                            // },
                    });
                });
            },
            error: function (error) {
                console.log(error);
            }
        });
    }
</script>

后端代码：

}

WeixinShareUtil(RedisUtils redisUtils) {

}

下期说我到底是怎么解决H5里的分享问题。
