这篇文章主要介绍了asp.net微信开发中有关高级群发图文的相关内容，需要的朋友可以参考下
上一篇介绍了如何群发文本消息，本篇将介绍如何群发图文信息，上传图文信息所需的素材，界面如下：
选择素材
确认选择
刷新
删除素材
本类型素材总数量为： 本次获取的素材数量为：
后台代码如下：
/// /// 绑定图文素材列表 /// private void BindNewsSucaiList() { WeiXinServer wxs = new WeiXinServer(); string res = ""; ///从缓存读取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果为空，重新获取 Access_token = wxs.GetAccessToken(); //设置缓存的数据7000秒后过期 Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } string Access_tokento = Access_token.Substring(17, Access_token.Length - 37); string posturl = "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=" + Access_tokento; //POST数据例子： POST数据例子：{"type":TYPE,"offset":OFFSET,"count":COUNT} string postData = "{"type":"news","offset":"0","count":"20"}"; res = wxs.GetPage(posturl, postData); //使用前需要引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(res); int groupsnum = jsonObj["item"].Count(); List newssucaiitemlist = new List(); List WxNewsSuCaiItemlist = new List(); for (int i = 0; i < groupsnum; i++) { WxNewsSucaiIteminfo newssucaiitem = new WxNewsSucaiIteminfo(); newssucaiitem.media_id = jsonObj["item"][i]["media_id"].ToString(); newssucaiitem.update_time = jsonObj["item"][i]["update_time"].ToString(); newssucaiitem.total_count = jsonObj["total_count"].ToString(); newssucaiitem.item_count = jsonObj["item_count"].ToString(); newssucaiitemlist.Add(newssucaiitem); int news_itemcount = jsonObj["item"][i]["content"]["news_item"].Count(); if (news_itemcount > 0) { for (int j = 0; j < news_itemcount; j++) { WxNewsSuCaiItemlistinfo wnscilinfo = new WxNewsSuCaiItemlistinfo(); wnscilinfo.title = jsonObj["item"][i]["content"]["news_item"][j]["title"].ToString(); wnscilinfo.thumb_media_id = jsonObj["item"][i]["content"]["news_item"][j]["thumb_media_id"].ToString(); wnscilinfo.show_cover_pic = int.Parse(jsonObj["item"][i]["content"]["news_item"][j]["show_cover_pic"].ToString()); wnscilinfo.author = jsonObj["item"][i]["content"]["news_item"][j]["author"].ToString(); wnscilinfo.digest = jsonObj["item"][i]["content"]["news_item"][j]["digest"].ToString(); wnscilinfo.content = jsonObj["item"][i]["content"]["news_item"][j]["content"].ToString(); wnscilinfo.url = jsonObj["item"][i]["content"]["news_item"][j]["url"].ToString(); wnscilinfo.content_source_url = jsonObj["item"][i]["content"]["news_item"][j]["content_source_url"].ToString(); wnscilinfo.media_id = newssucaiitem.media_id.ToString(); WxNewsSuCaiItemlist.Add(wnscilinfo); } } } Session["WxNewsSuCaiItemlist"] = WxNewsSuCaiItemlist; this.Repeatersucailist.DataSource = newssucaiitemlist; this.Repeatersucailist.DataBind(); }
再来看看，新建单图文信息界面：
新建单图文上传封面，删除封面的代码如下：
/// /// /// 上传图片文件 ///
protected void LinkBtnSubSend_Click(object sender, EventArgs e) { //根据单选按钮判断类型，//如果选择的是图文消息 if (this.RadioBtnList.SelectedValue.ToString().Equals("1")) { if (String.IsNullOrWhiteSpace(this.lbtuwenmedai_id.Text.ToString().Trim())) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('请选择或新建图文素材再进行群发！');", true); return; } WxMassService wms = new WxMassService(); List wxmaslist = wms.GetMonthMassCount(); if (wxmaslist.Count >= 4) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('本月可群发消息数量已达上限！');", true); return; } else { //如何群发类型为全部用户，根据openID列表群发给全部用户，订阅号不可用，服务号认证后可用 if (this.DDLMassType.SelectedValue.ToString().Equals("0")) { StringBuilder sbs = new StringBuilder(); sbs.Append(GetAllUserOpenIDList()); WeiXinServer wxs = new WeiXinServer(); ///从缓存读取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果为空，重新获取 Access_token = wxs.GetAccessToken(); //设置缓存的数据7000秒后过期 Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration); } string Access_tokento = Access_token.Substring(17, Access_token.Length - 37); string posturl = "https://api.weixin.qq.com/cgi-bin/message/mass/send?access_token=" + Access_tokento; ///群发POST数据示例如下： // { // "touser":[ // "OPENID1", // "OPENID2" // ], // "mpnews":{ // "media_id":"123dsdajkasd231jhksad" // }, // "msgtype":"mpnews" //} string postData = "{"touser":[" + sbs.ToString() + "],"mpnews":{"media_id":"" + this.lbtuwenmedai_id.Text.ToString() + ""},"msgtype":"mpnews"}"; string tuwenres = wxs.GetPage(posturl, postData); //使用前需药引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(tuwenres); if (jsonObj["errcode"].ToString().Equals("0")) { Session["media_id"] = null; WxMassInfo wmi = new WxMassInfo(); if (Session["wmninfo"] != null) { WxMpNewsInfo wmninfo = Session["wmninfo"] as WxMpNewsInfo; wmi.title = wmninfo.title.ToString(); wmi.contents = wmninfo.contents.ToString();

return; } } } } }
为什么叫群发任务提交成功或失败，因为将信息提交给微信服务器，微信服务器还需审核，审核过程中也有可能审核不通过，不给于群发，所以我起名叫这个，嘿嘿，随便你们怎么起。。。。。
/// /// 微信已群发消息实体类，用于记录已群发消息的条数，信息实体 /// public class WxMassInfo { public int WxMassNo { get; set; }//群发消息编号，数据库自增列 public string title { get; set; }//图文消息的标题，若消息是文本类型，此项不显示 public string ImageUrl { get; set; }//图片地址，若消息是文本类型，此项不显示 public string type { get; set; }//消息的类型，文本，图文，图片，语音，视频 public string contents { get; set; }//文本消息的内容，图文消息的正文 public string massObject { get; set; }//群发对象 public string massStatus { get; set; }//群发状态 public string massMessageID{ get; set; }//群发成功后返回的消息ID public string massDate { get; set; }//群发日期时间 }
以上就是本文的全部内容，希望对大家的学习有所帮助。
