微信朋友圈转发第三方网站带缩略图实现

简介: 前情提要 有时候我们会在朋友圈看到如下两种转发情况:一种是前面带缩略图的 ,一种是无缩略图的,当然有缩略图的不管是从用户体验,还是网站推广运营方都是更优的选择。 那我们看看微信分享朋友圈缩略图是 怎么一回事呢 注:微信6.5.5版本后,微信调整了分享规则。

前情提要

有时候我们会在朋友圈看到如下两种转发情况:一种是前面带缩略图的 ,一种是无缩略图的,当然有缩略图的不管是从用户体验,还是网站推广运营方都是更优的选择。

那我们看看微信分享朋友圈缩略图是 怎么一回事呢

注:微信6.5.5版本后,微信调整了分享规则。以前的没有通过认证公众号jssdk注入分享的都不是官方认可的分享。

必要前提:① 所打开的分享网页 域名必须经过备案(备案过的二级域名也行) ②公众号后台基本配置里面获取AppID和AppSecret 以添加服务器IP到白名单 显示如下:

 

 代码实现

 在HTML的Body下 加入如下代码:

<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
    <script>
                var dataForWeixin = {
                    appId: '@ViewBag.appid',
                    url: '@ViewBag.url',
                    jsapiTicket:'@ViewBag.jsapiTicket',
                    title: '转发标题',
                    imgUrl: '服务器上需要显示的图片路径',
                    timestamp: '@ViewBag.timestamp',
                    nonceStr: '@ViewBag.nonceStr',
                    signature: '@ViewBag.signature',
                    jsApiList: ['onMenuShareTimeline','onMenuShareAppMessage'],
                    callback: function () { }
                };
              wx.config({
                  debug: false,
                  appId: dataForWeixin.appId,
                  timestamp: dataForWeixin.timestamp,
                  nonceStr: dataForWeixin.nonceStr,
                  signature: dataForWeixin.signature,
                  jsApiList: dataForWeixin.jsApiList
              });
    </script>
    <div style="height:0px;overflow:hidden;">
        <img src="服务器上需要显示的图片路径" />
    </div>

在控制器中加入一个 获取微信分享接口的参数如下(再程序入口调用此方法即可)

     /// <summary>
        /// 获取微信分享接口参数
        /// </summary>
        public void GetWX()
        {

            string app_id = ConfigHelper.AppId;
            string AppSecret = ConfigHelper.AppSecret;
            writeLog.WriteLogs("app_id,AppSecret:" + app_id + AppSecret + "");
            Wx_helper jssdk = new Wx_helper(app_id, AppSecret);
            Hashtable ht = jssdk.getSignPackage();
            // 遍历哈希表
            foreach (DictionaryEntry de in ht)
            {
                if (de.Key.ToString() == "appId")
                {
                    ViewBag.appid = de.Value.ToString();
                }
                if (de.Key.ToString() == "nonceStr")
                {
                    ViewBag.nonceStr = de.Value.ToString();
                }
                if (de.Key.ToString() == "timestamp")
                {
                    ViewBag.timestamp = de.Value.ToString();
                }
                if (de.Key.ToString() == "url")
                {
                    ViewBag.url = de.Value.ToString();
                }
                if (de.Key.ToString() == "signature")
                {
                    ViewBag.signature = de.Value.ToString();
                }
                if (de.Key.ToString() == "jsapiTicket")
                {
                    ViewBag.jsapiTicket = de.Value.ToString();
                }
            }
        }

另外,微信接口类 继承 了 DBBase ,里面只有连接数据库对象,这个可以根据自己项目特点和需要处理 这里只做演示:

   public class DBBase
    {
        protected static string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
        public SqlHelper sqlhelp = new SqlHelper(connectionString);
    }
