微信公众号分享格式自定义

微信文章默认分享格式是标题，摘要，和一个图片。公众号文章分享是类似这个格式。

但非公众号网页，比如自己的H5网页，则要写一定的代码才能实现

调试时，要把wx.config({  debug: true}} 打开，不然你找不到错误。

后台代码生成timestamp，nonceStr，signature：

       public  long CreatenTimestamp(){return (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000;}public  string CreatenNonce_str(){string[] strs = new string[]{"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};Random r = new Random();var sb = new StringBuilder();var length = strs.Length;for (int i = 0; i < 15; i++){sb.Append(strs[r.Next(length - 1)]);}return sb.ToString();}public  string GetSignature(string jsapi_ticket, string timestamp, string nonce, string url){url = url.IndexOf("#") >= 0 ? url.Substring(0, url.IndexOf("#")) : url;string tmpStr = "jsapi_ticket=" + jsapi_ticket + "&noncestr=" + nonce + "×tamp=" + timestamp + "&url=" + url;tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1").ToLower();return tmpStr;}

写完之后，假如你没有在公众号后台设置，一定会碰到这个错误。

调试返回参数：

{ "errMsg": "config:invalid url domain" }

截图：

环境：

微信测试号，非正式的公共号

说明：

需要在公众号设置=》 功能设置里配置
