asp.net微信开发中永久素材管理介绍

除了3天就会失效的临时素材外，开发者有时需要永久保存一些素材，届时就可以通过本接口新增永久素材。

最近更新，永久图片素材新增后，将带有URL返回给开发者，开发者可以在腾讯系域名内使用（腾讯系域名外使用，图片将被屏蔽）。

请注意：

• 1、新增的永久素材也可以在公众平台官网素材管理模块中看到

• 2、永久素材的数量是有上限的，请谨慎新增。图文消息素材和图片素材的上限为5000，其他类型为1000

• 3、素材的格式大小等要求与公众平台官网一致。具体是，图片大小不超过2M，支持bmp/png/jpeg/jpg/gif格式，语音大小不超过5M，长度不超过60秒，支持mp3/wma/wav/amr格式

先来看我自己自定义的后台永久素材管理效果图，如下：

再看看微信官网后台上的显示界面，同步的哦！

首先我们来分析一下步骤：

/// <summary>   /// 微信永久素材实体类，用于保存永久素材上传至微信服务器后返回的数据   /// </summary>   public class WxSuCaiInfo   {   public int SuCaiId { get; set; }//自增列序号     public string SuCaiUrl { get; set; }// 存储文件名     public string SuCaiType { get; set; }//素材类型，可分为image,voice,video,thumb(缩略图)     public string SuCaiTitle { get; set; }//图文消息的标题     public string SuCaiDigest { get; set; }//图文消息的摘要       public string SuCaiauthor { get; set; }//图文消息的作者   public string SuCaishow_cover_pic { get; set; }//图文消息是否显示封面.保存0或1     public string SuCaicontent { get; set; }//图文消息的正文内容   public string SuCaicontent_source_url { get; set; }//图文消息的原文链接       public string media_ID { get; set; }//上传至微信服务器后，返回的永久mediaID       public string Url { get; set; }//上传至微信服务器后，返回的图片URL，仅图片才会返回此属性     public string uploadDate { get; set; }//上传日期时间       }

 /// <summary>   /// 上传图片至微信服务器,并且本地也保存一份   /// </summary>   /// <param name="sender"></param>   /// <param name="e"></param>   protected void LinBtnUploadImg_Click(object sender, EventArgs e)   {    if (this.FileUploadImage.HasFile)    {    string fileContentType = FileUploadImage.PostedFile.ContentType;    if (fileContentType == "image/bmp" || fileContentType == "image/gif" || fileContentType == "image/png" || fileContentType == "image/x-png" || fileContentType == "image/jpeg"     || fileContentType == "image/pjpeg")    {     int fileSize = this.FileUploadImage.PostedFile.ContentLength;       if (fileSize <= 2097152)     {     string fileName = this.FileUploadImage.PostedFile.FileName;     // 客户端文件路径     string filepath = FileUploadImage.PostedFile.FileName; //得到的是文件的完整路径,包括文件名，如：C:\Documents and Settings\Administrator\My Documents\My Pictures\20022775_m.jpg      //string filepath = FileUpload1.FileName;  //得到上传的文件名20022775_m.jpg      string filename = filepath.Substring(filepath.LastIndexOf("\\") + 1);//20022775_m.jpg      string serverpath = Server.MapPath("~/WeiXinImg/") + filename;//取得文件在服务器上保存的位置C:\Inetpub\wwwroot\WebSite1\images\20022775_m.jpg       //把图片上传至本地服务器     this.FileUploadImage.PostedFile.SaveAs(serverpath);//将上传的文件另存为         //上传图片素材至微信服务器,永久保存       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 url = string.Format("http://api.weixin.qq.com/cgi-bin/material/add_material?access_token={0}&type={1}", Access_tokento,"image");       try     {        string res = HttpUploadFile(url, serverpath);      //判断res结果集里面是否包含media_id      if (res.Contains("media_id"))      {      //如果能进行到这里，那说明图片已经上传至微信服务器，是永久素材哦，      //开始解析json串，使用前需要引用Newtonsoft.json.dll文件      JObject jsonObj = JObject.Parse(res);                //图片上传成功后，返回的是两个字段，media_id和url          //将两个字段开始存入数据库，保存数据，方便获取列表的时候直接从本地服务器读取      WxSuCaiInfo wsc = new WxSuCaiInfo();        wsc.SuCaiUrl = filename;//注意，这里保存的图片名称        wsc.SuCaiType = "image";//文件类型        wsc.media_ID = jsonObj["media_id"].ToString();//这个属性保存的是微信返回的media_id        wsc.Url = jsonObj["url"].ToString();//这个属性保存的才是微信返回的url        wsc.uploadDate = System.DateTime.Now.ToString();//记录当前文件上传日期时间        //存入数据库      WxSuCaiService wscs = new WxSuCaiService();          int num = wscs.AddWxSuCaiInfo(wsc);        if (num > 0)      {       Response.Write("<script>alert('上传图片素材成功！');location='WxSuCaiMannageImageList.aspx';</script>");      }      else      {       Response.Write("<script>alert('上传图片素材失败！');location='WxSuCaiMannageImageList.aspx';</script>");      }      }     }     catch(Exception ex)     {      Response.Write(ex.Message.ToString());     }     }     else     {     Response.Write("<script>alert('上传文件不能大于2M！')</script>");     }      }    else    {     Response.Write("<script>alert('只支持BMP,GIF,PNG,JPG,JPEG格式的图片！')</script>");    }    }    else    {    Response.Write("<script>alert('请选择图片！')</script>");    }   }

走到这其实效果已经出来了，接下来看最后一步就是删除选中的素材，删除微信远程服务器的数据--再删除本地服务器的数据，有人问难道这个还有顺序？其实你可以想象，如果微信服务器的图片没有删除成功，你先把本地服务器的图片删除了，那就和官网同步不了了。

从图片库选择图片素材如下：

 /// <summary>   /// 确认选择，选中之后，跳转至新建图文页面   /// </summary>   /// <param name="sender"></param>   /// <param name="e"></param>   protected void LinkBtnSubMitSelected_Click(object sender, EventArgs e)   {      Boolean bools = false;    int num = 0;    foreach (DataListItem item in this.DLSuCaiImageList.Items)    {    CheckBox checkIn = item.FindControl("CheckIn") as CheckBox;      if (checkIn.Checked)    {     num += 1;     bools = true;    }    }    if (!bools)    {    ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('请选择一个图片素材！！！')", true);    return;    }    if (num >= 2)    {    ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('您只能选择一个图片素材！');", true);    return;    }    else    {    foreach (DataListItem item in this.DLSuCaiImageList.Items)    {     CheckBox checkIn = item.FindControl("CheckIn") as CheckBox;       if (checkIn.Checked)     {     ///获取选中图片media_id     Label lbmedia_ID = item.FindControl("lbmedia_ID") as Label;     Session["imgmedia_id"] = lbmedia_ID.Text.ToString();     Response.Write("<script>alert('已选择！');window.opener.location.reload();window.close();</script>");     }    }    }   }

 if (Session["imgmedia_id"] != null)     {     WxSuCaiService wscs = new WxSuCaiService();       WxSuCaiInfo wscinfo = wscs.GetWxSuCaiInfo(Session["imgmedia_id"].ToString());       if(wscinfo!=null)     {      this.ImgTuWen.ImageUrl = "~/WeiXinImg/" + wscinfo.SuCaiUrl.ToString();      this.ImgTuWen2.ImageUrl = "~/WeiXinImg/" + wscinfo.SuCaiUrl.ToString();      this.ImgTuWen2.Visible = true;      Session["imgmedia_id"] = wscinfo.media_ID.ToString();//图片的media_id      Session["fileNameimg"] = wscinfo.SuCaiUrl.ToString();//图片的文件名称     }         }

最后新建图文信息的效果图如下：

官方后台如下：

 /// <summary>   /// 绑定事件   /// </summary>   /// <param name="sender"></param>   /// <param name="e"></param>   protected void DLMpNewsList_ItemDataBound(object sender, DataListItemEventArgs e)   {    if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem)    {    LinkButton LinkBtnDeleteSucai = e.Item.FindControl("LinkBtnDeleteSucai") as LinkButton;        LinkBtnDeleteSucai.Attributes.Add("OnClick","return confirm('您确定删除该图文素材？？？删除后将和微信官网同步删除！！')");        HyperLink HyperLinkEdit = e.Item.FindControl("HyperLinkEdit") as HyperLink;      HyperLinkEdit.Attributes.Add("OnClick", "return confirm('即将进入编辑模式！！是否执行下一步操作？？')");        Label lbmedia_ID = e.Item.FindControl("lbmedia_ID") as Label;        HyperLinkEdit.NavigateUrl = "WxNewTuWen.aspx?media_id=" + lbmedia_ID.Text.ToString();//把图文消息的media_id传参到新建图文界面      }   }

 if(!Page.IsPostBack)    {    ///编辑模式    if (Request.QueryString["media_id"] != null)    {     string media_id = Request.QueryString["media_id"].ToString();       Session["sucaimedia_id"] = media_id;       WxSuCaiService wscs = new WxSuCaiService();         WxSuCaiInfo wscinfo = wscs.GetWxSuCaiInfo(media_id);       if (wscinfo != null)     {     this.txttuwen_title.Value = wscinfo.SuCaiTitle.ToString();       if (wscinfo.SuCaiTitle.ToString().Length > 15)     {      this.biaoti_yulan.InnerText = wscinfo.SuCaiTitle.ToString().Substring(0, 15) + "...";     }     else     {      this.biaoti_yulan.InnerText = wscinfo.SuCaiTitle.ToString();     }       this.txttuwen_author.Value = wscinfo.SuCaiauthor.ToString();     this.txtzhaiyao.InnerText = wscinfo.SuCaiDigest.ToString();     this.ImgTuWen.ImageUrl = "~/WeiXinImg/" + wscinfo.SuCaiUrl.ToString();     this.ImgTuWen2.ImageUrl = "~/WeiXinImg/" + wscinfo.SuCaiUrl.ToString();     this.ImgTuWen2.Visible = true;     Session["imgmedia_id"] = wscinfo.SuCaithumb_media_id.ToString();     this.LinkBtnDeleteImg.Visible = true;       if (!String.IsNullOrWhiteSpace(wscinfo.SuCaicontent_source_url.ToString()))     {      this.txtYuanWenUrl.Text = wscinfo.SuCaicontent_source_url.ToString();      this.txtYuanWenUrl.Visible = true;      this.CheckYuanWen.Checked = true;     }       this.txtYuanWenUrl.Text = wscinfo.SuCaicontent_source_url.ToString();       this.tbContent.InnerText = wscinfo.SuCaicontent.ToString();         if (wscinfo.SuCaishow_cover_pic.ToString().Equals("1"))     {      this.CheckFengMianShow.Checked = true;     }     else     {      this.CheckFengMianShow.Checked = false;     }     }    }    }
