除了3天就會(huì)失效的臨時(shí)素材外,開發(fā)者有時(shí)需要永久保存一些素材,屆時(shí)就可以通過本接口新增永久素材。
最近更新,永久圖片素材新增后,將帶有URL返回給開發(fā)者,開發(fā)者可以在騰訊系域名內(nèi)使用(騰訊系域名外使用,圖片將被屏蔽)。
請(qǐng)注意:
先來看我自己自定義的后臺(tái)永久素材管理效果圖,如下:
再看看微信官網(wǎng)后臺(tái)上的顯示界面,同步的哦!
首先我們來分析一下步驟:
第一步:如果想讓圖片在自己的頁(yè)面顯示,首先得先建個(gè)實(shí)體類吧,用來存儲(chǔ)素材的信息吧
/// summary> /// 微信永久素材實(shí)體類,用于保存永久素材上傳至微信服務(wù)器后返回的數(shù)據(jù) /// /summary> public class WxSuCaiInfo { public int SuCaiId { get; set; }//自增列序號(hào) public string SuCaiUrl { get; set; }// 存儲(chǔ)文件名 public string SuCaiType { get; set; }//素材類型,可分為image,voice,video,thumb(縮略圖) public string SuCaiTitle { get; set; }//圖文消息的標(biāo)題 public string SuCaiDigest { get; set; }//圖文消息的摘要 public string SuCaiauthor { get; set; }//圖文消息的作者 public string SuCaishow_cover_pic { get; set; }//圖文消息是否顯示封面.保存0或1 public string SuCaicontent { get; set; }//圖文消息的正文內(nèi)容 public string SuCaicontent_source_url { get; set; }//圖文消息的原文鏈接 public string media_ID { get; set; }//上傳至微信服務(wù)器后,返回的永久mediaID public string Url { get; set; }//上傳至微信服務(wù)器后,返回的圖片URL,僅圖片才會(huì)返回此屬性 public string uploadDate { get; set; }//上傳日期時(shí)間 }
第二步:上傳圖片至微信服務(wù)器,成功后將返回的media_id和url兩個(gè)字段數(shù)據(jù)和其他字段數(shù)據(jù)一并保存到本地服務(wù)器,上傳的代碼如下:
/// summary> /// 上傳圖片至微信服務(wù)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; // 客戶端文件路徑 string filepath = FileUploadImage.PostedFile.FileName; //得到的是文件的完整路徑,包括文件名,如:C:\Documents and Settings\Administrator\My Documents\My Pictures\20022775_m.jpg //string filepath = FileUpload1.FileName; //得到上傳的文件名20022775_m.jpg string filename = filepath.Substring(filepath.LastIndexOf("\\") + 1);//20022775_m.jpg string serverpath = Server.MapPath("~/WeiXinImg/") + filename;//取得文件在服務(wù)器上保存的位置C:\Inetpub\wwwroot\WebSite1\images\20022775_m.jpg //把圖片上傳至本地服務(wù)器 this.FileUploadImage.PostedFile.SaveAs(serverpath);//將上傳的文件另存為 //上傳圖片素材至微信服務(wù)器,永久保存 WeiXinServer wxs = new WeiXinServer(); ///從緩存讀取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果為空,重新獲取 Access_token = wxs.GetAccessToken(); //設(shè)置緩存的數(shù)據(jù)7000秒后過期 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); //判斷res結(jié)果集里面是否包含media_id if (res.Contains("media_id")) { //如果能進(jìn)行到這里,那說明圖片已經(jīng)上傳至微信服務(wù)器,是永久素材哦, //開始解析json串,使用前需要引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(res); //圖片上傳成功后,返回的是兩個(gè)字段,media_id和url //將兩個(gè)字段開始存入數(shù)據(jù)庫(kù),保存數(shù)據(jù),方便獲取列表的時(shí)候直接從本地服務(wù)器讀取 WxSuCaiInfo wsc = new WxSuCaiInfo(); wsc.SuCaiUrl = filename;//注意,這里保存的圖片名稱 wsc.SuCaiType = "image";//文件類型 wsc.media_ID = jsonObj["media_id"].ToString();//這個(gè)屬性保存的是微信返回的media_id wsc.Url = jsonObj["url"].ToString();//這個(gè)屬性保存的才是微信返回的url wsc.uploadDate = System.DateTime.Now.ToString();//記錄當(dāng)前文件上傳日期時(shí)間 //存入數(shù)據(jù)庫(kù) WxSuCaiService wscs = new WxSuCaiService(); int num = wscs.AddWxSuCaiInfo(wsc); if (num > 0) { Response.Write("script>alert('上傳圖片素材成功!');location='WxSuCaiMannageImageList.aspx';/script>"); } else { Response.Write("script>alert('上傳圖片素材失敗!');location='WxSuCaiMannageImageList.aspx';/script>"); } } } catch(Exception ex) { Response.Write(ex.Message.ToString()); } } else { Response.Write("script>alert('上傳文件不能大于2M!')/script>"); } } else { Response.Write("script>alert('只支持BMP,GIF,PNG,JPG,JPEG格式的圖片!')/script>"); } } else { Response.Write("script>alert('請(qǐng)選擇圖片!')/script>"); } }
走到這其實(shí)效果已經(jīng)出來了,接下來看最后一步就是刪除選中的素材,刪除微信遠(yuǎn)程服務(wù)器的數(shù)據(jù)--再刪除本地服務(wù)器的數(shù)據(jù),有人問難道這個(gè)還有順序?
其實(shí)你可以想象,如果微信服務(wù)器的圖片沒有刪除成功,你先把本地服務(wù)器的圖片刪除了,那就和官網(wǎng)同步不了了。
第三步:刪除素材
/// summary> /// 全選全不選 /// /summary> /// param name="sender">/param> /// param name="e">/param> protected void CheckAll_CheckedChanged(object sender, EventArgs e) { foreach (DataListItem item in this.DLSuCaiImageList.Items) { CheckBox checkIn = item.FindControl("CheckIn") as CheckBox; checkIn.Checked = CheckAll.Checked; } } /// summary> /// 刪除選中項(xiàng) /// /summary> /// param name="sender">/param> /// param name="e">/param> protected void LinkBtnDeleteSelected_Click(object sender, EventArgs e) { Boolean ischeck = false; foreach (DataListItem item in this.DLSuCaiImageList.Items) { CheckBox checkIn = item.FindControl("CheckIn") as CheckBox; if (checkIn.Checked) { ischeck = true; Label lbSuCaiId = item.FindControl("lbSuCaiId") as Label; Label lbSuCaiUrl = item.FindControl("lbSuCaiUrl") as Label; Label lbmedia_ID = item.FindControl("lbmedia_ID") as Label; //刪除微信服務(wù)器上的圖片 WeiXinServer wxs = new WeiXinServer(); string res = ""; ///從緩存讀取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果為空,重新獲取 Access_token = wxs.GetAccessToken(); //設(shè)置緩存的數(shù)據(jù)7000秒后過期 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/del_material?access_token=" + Access_tokento; //POST數(shù)據(jù)例子: POST數(shù)據(jù)例子:{"media_id":MEDIA_ID} string media_id = lbmedia_ID.Text.ToString(); string postData = "{\"media_id\":\"" + media_id + "\"}"; res = wxs.GetPage(posturl, postData); if (res.Contains("errcode")) { //開始解析json串,使用前需要引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(res); if (jsonObj["errcode"].ToString().Equals("0")) { ///獲取本地服務(wù)器的路徑 string serverPathss = Server.MapPath("~/WeiXinImg/") + lbSuCaiUrl.Text.ToString(); //驗(yàn)證本地服務(wù)的路徑是否存在該圖片 if (File.Exists(serverPathss)) { //如果存在就刪除 File.Delete(serverPathss); } WxSuCaiService wscs = new WxSuCaiService(); //通過media_id刪除本地服務(wù)器數(shù)據(jù)庫(kù)記錄 int num = wscs.DeleteWxSuCaiInfo(lbmedia_ID.Text.ToString()); if (num > 0) { Response.Write("script>alert('圖片素材刪除成功!');location='WxSuCaiMannageImageList.aspx';/script>"); } else { Response.Write("script>alert('微信服務(wù)器圖片刪除成功!本地服務(wù)器圖片素材刪除失??!');location='WxSuCaiMannageImageList.aspx';/script>"); } } } } } if (!ischeck) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('請(qǐng)先選中刪除項(xiàng)!??!')", true); return; } }
最后是頁(yè)面的代碼一并奉上,大家仔細(xì)研究。

其他素材上傳都類似,就不一一介紹了。
新建圖文素材界面如下:
從圖片庫(kù)選擇圖片素材如下:
這是就是從已上傳過的圖片庫(kù)中選擇的,和圖片素材管理界面的功能基本相似,只不過多了一個(gè)確認(rèn)選擇的按鈕,因?yàn)榇_認(rèn)選擇了之后,要關(guān)閉本頁(yè),回到新建圖文頁(yè)面,主要代碼:
/// summary> /// 確認(rèn)選擇,選中之后,跳轉(zhuǎn)至新建圖文頁(yè)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('請(qǐng)選擇一個(gè)圖片素材?。。?)", true); return; } if (num >= 2) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('您只能選擇一個(gè)圖片素材!');", true); return; } else { foreach (DataListItem item in this.DLSuCaiImageList.Items) { CheckBox checkIn = item.FindControl("CheckIn") as CheckBox; if (checkIn.Checked) { ///獲取選中圖片media_id Label lbmedia_ID = item.FindControl("lbmedia_ID") as Label; Session["imgmedia_id"] = lbmedia_ID.Text.ToString(); Response.Write("script>alert('已選擇!');window.opener.location.reload();window.close();/script>"); } } } }
新建圖文的頁(yè)面在接收的時(shí)候可以這樣:
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();//圖片的media_id Session["fileNameimg"] = wscinfo.SuCaiUrl.ToString();//圖片的文件名稱 } }
最后新建圖文信息的效果圖如下:
官方后臺(tái)如下:
關(guān)于編輯圖文信息的關(guān)鍵代碼如下:
/// summary> /// 綁定事件 /// /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('您確定刪除該圖文素材???刪除后將和微信官網(wǎng)同步刪除?。?)"); HyperLink HyperLinkEdit = e.Item.FindControl("HyperLinkEdit") as HyperLink; HyperLinkEdit.Attributes.Add("OnClick", "return confirm('即將進(jìn)入編輯模式??!是否執(zhí)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();//把圖文消息的media_id傳參到新建圖文界面 } }
新建圖文頁(yè)面關(guān)鍵代碼如下:
if(!Page.IsPostBack) { ///編輯模式 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; } } } }
編輯提交關(guān)鍵代碼如下:
/// summary> /// 保存圖文素材和修改按鈕公用 /// /summary> /// param name="sender">/param> /// param name="e">/param> protected void LinkBtnSaveYongjiu_Click(object sender, EventArgs e) { //非空驗(yàn)證 if (String.IsNullOrWhiteSpace(this.txttuwen_title.Value.ToString())) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('請(qǐng)輸入圖文標(biāo)題!');", true); return; } if (this.ImgTuWen2.ImageUrl.ToString().Equals("")) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('必須上傳一張圖片!');", true); return; } if (String.IsNullOrWhiteSpace(this.tbContent.InnerText.ToString())) { ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "alert('請(qǐng)輸入正文內(nèi)容!');", true); return; } //對(duì)各項(xiàng)進(jìn)行賦值 WeiXinServer wxs = new WeiXinServer(); ///從緩存讀取accesstoken string Access_token = Cache["Access_token"] as string; if (Access_token == null) { //如果為空,重新獲取 Access_token = wxs.GetAccessToken(); //設(shè)置緩存的數(shù)據(jù)7000秒后過期 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); //根據(jù)session判斷media_id是否為空,也可根據(jù)request.queryString["media_id"]進(jìn)行判斷是否為空 if (Session["sucaimedia_id"] != null) { //執(zhí)行更新操作 //{ // "media_id":MEDIA_ID, // "index":INDEX, // "articles": { // "title": TITLE, // "thumb_media_id": THUMB_MEDIA_ID, // "author": AUTHOR, // "digest": DIGEST, // "show_cover_pic": SHOW_COVER_PIC(0 / 1), // "content": CONTENT, // "content_source_url": CONTENT_SOURCE_URL // } //} string isshow_cover_pic = ""; if (this.CheckFengMianShow.Checked) { isshow_cover_pic = "1"; } else { isshow_cover_pic = "0"; } string description = NoHTML(this.tbContent.InnerText.ToString()); string postData = "{\"media_id\":\"" + Session["sucaimedia_id"].ToString() + "\",\"index\":\"0\" ,\"articles\":{\"title\":\"" + this.txttuwen_title.Value.ToString() + "\",\"thumb_media_id\":\"" + Session["imgmedia_id"].ToString() + "\",\"author\":\"" + this.txttuwen_author.Value.ToString() + "\",\"digest\":\"" + this.txtzhaiyao.InnerText.ToString() + "\",\"show_cover_pic\":\"" + isshow_cover_pic + "\",\"content\":\"" + description + "\",\"content_source_url\":\"" + this.txtYuanWenUrl.Text.ToString() + "\"}}"; ///修改永久圖文素材 string url = string.Format("https://api.weixin.qq.com/cgi-bin/material/update_news?access_token={0}", Access_tokento); string jsonres = PostUrl(url, postData); if (jsonres.Contains("errcode")) { //使用前需要引用Newtonsoft.json.dll文件 JObject jsonObj = JObject.Parse(jsonres); if (jsonObj["errcode"].ToString().Equals("0")) { //修改本地?cái)?shù)據(jù) //保存數(shù)據(jù),方便獲取列表的時(shí)候直接從本地服務(wù)器讀取 WxSuCaiInfo wsc = new WxSuCaiInfo(); wsc.SuCaiUrl = Session["fileNameimg"].ToString();//注意,這里保存的圖片名稱 wsc.SuCaiTitle = this.txttuwen_title.Value.ToString();//圖文消息的標(biāo)題 wsc.SuCaiDigest = this.txtzhaiyao.InnerText.ToString();//圖文消息的摘要 wsc.SuCaithumb_media_id = Session["imgmedia_id"].ToString();//圖文的消息封面media_id wsc.SuCaiauthor = this.txttuwen_author.Value.ToString(); wsc.SuCaishow_cover_pic = isshow_cover_pic; wsc.SuCaicontent = description; wsc.SuCaicontent_source_url = this.txtYuanWenUrl.Text.ToString(); wsc.uploadDate = System.DateTime.Now.ToString();//記錄當(dāng)前文件保存圖文素材日期時(shí)間 //修改數(shù)據(jù)庫(kù)信息 WxSuCaiService wscs = new WxSuCaiService(); int num = wscs.UpdateWxSuCaiInfo(Session["sucaimedia_id"].ToString(), wsc); if (num > 0) { Session["sucaimedia_id"] = null; Response.Write("script>alert('圖文素材修改成功!');location='WxSuCaiManageList.aspx';/script>"); } else { Response.Write("script>alert('圖文素材修改失??!');/script>"); } } } } else { //新增圖文素材 } }
需注意:新建圖文頁(yè)面和修改圖文頁(yè)面是公用的一個(gè)頁(yè)面.......
編輯提交按鈕和保存按鈕是公用的一個(gè)按鈕.....
