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：

asp.net微信开发（高级群发图文）

我们先看从素材库中获取图文素材的代码，界面：

asp.net微信开发（高级群发图文）

素材列表，我是使用的repeater控件，

前台代码如下：

 <!--弹出选择素材窗口-->
  <div id="shownewgroup">
  <div class="closeLogin" style="height:40px; background-color:#ddd9ff; line-height:40px;"><span style="float:left; color:#000; font-size:14px; text-indent:5px;">选择素材</span>
  <span style="float:left;margin-left:20px;"><a href="WxNewTuWen.aspx" style="color:red;" onclick="hrefurl();" class="hrefurl">新建图文素材</a></span>
  <a class="closeloginpage"><img src="/UploadFiles/2021-04-02/close1.png">


后台代码如下：







 /// <summary>
 /// 绑定图文素材列表
 /// </summary>
 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_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<WxNewsSucaiIteminfo> newssucaiitemlist = new List<WxNewsSucaiIteminfo>();
  List<WxNewsSuCaiItemlistinfo> WxNewsSuCaiItemlist = new List<WxNewsSuCaiItemlistinfo>();
  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：

  Response.Redirect("WxMassManage.aspx" + jsonObj["media_id"].ToString());
  }
 }
 /// <summary> 
 /// 请求Url，发送数据 
 /// </summary> 
 public static string PostUrl(string url, string postData)
 {
  byte[] data = Encoding.UTF8.GetBytes(postData);

  // 设置参数 
  HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
  CookieContainer cookieContainer = new CookieContainer();
  request.CookieContainer = cookieContainer;
  request.AllowAutoRedirect = true;
  request.Method = "POST";
  request.ContentType = "application/x-www-form-urlencoded";
  request.ContentLength = data.Length;
  Stream outstream = request.GetRequestStream();
  outstream.Write(data, 0, data.Length);
  outstream.Close();

  //发送请求并获取相应回应数据 
  HttpWebResponse response = request.GetResponse() as HttpWebResponse;
  //直到request.GetResponse()程序才开始向目标网页发送Post请求 
  Stream instream = response.GetResponseStream();
  StreamReader sr = new StreamReader(instream, Encoding.UTF8);
  //返回结果网页（html）代码 
  string content = sr.ReadToEnd();
  return content;
 }






Response.Redirect("WxMassManage.aspx" + jsonObj["media_id"].ToString());

这句代码就是将上传图文后得到的media_Id参数传送到群发界面，群发界面接收代码如下：







 protected void Page_Load(object sender, EventArgs e)
 {
  if(!Page.IsPostBack)
  {
  BindNewsSucaiList();//绑定素材列表
  BindGroupList();//绑定分组列表
  BindMassCount();//绑定本月已群发条数
  this.DataBind();
  if (Request.QueryString["media_id"] != null)
  {
   this.RadioBtnList.SelectedValue = "1";
   this.showExpress.Visible = false;
   this.txtwenben.Visible = false;
   this.tuwen.Visible = true;
   this.tuwenxuan.Visible = false;
   this.tuwenjian.Visible = false;
   this.lbtuwenmedai_id.Visible = true;
   this.lbtuwenmedai_id.Text = Request.QueryString["media_id"].ToString();
   this.LinkBtndeletetuwen.Visible = true;
   this.Imageyixuan.Visible = true;
  }
  }
 }





最终界面如下：

我这里只接收了一个media_id值，相对于做的简单，直接将值赋值给了一个label用于显示，也可以做成像官网那样，确定选择后，按照图文样式显示.

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。。。。。


asp.net微信开发（高级群发图文）


至此群发图文信息功能，已完毕，最后是群发记录，还记得上一章提到的群发成功之后要在本地保存记录吗，保存记录的原因，用于计算当月已群发几条信息，另外还有一个功能就是，群发成功之后，会得到一个消息msgid,根据这个ID可以对已经发送成功的信息进行撤销（删除）操作，关于撤销操作：微信官方规定，对群发成功的图文和视频消息，半个小时之内可以进行删除操作，其他消息一经群发成功概不支持此操作。截图如下：


asp.net微信开发（高级群发图文）


该类用于存储已群发记录的实体类







 /// <summary>
 /// 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
 /// </summary>
 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

 }
