微信公众号平台接口开发：发送客服消息

官方接口介绍

发送文本信息

参数有4个，

access_token这个就不用介绍了，就是之前得到的那个AccessToken，就是在这个接口里边当中参数用的

touser是关注了公众号的微信用户的openid，这个其实就是就是第一篇：微信公众号平台接口开发：成为开发者，里边的关注了测试账号的账户

我们再看一篇，就是圈起来的那个ID

msgtype=text是固定的；
content就是要发送的文本内容；

新增文本发送类MessageBase.cs、SingleMessageBase.cs、TextSingleMessage.cs

 1     public abstract class MessageBase
 2     {
 3         protected string requestUri;
 4 
 5         public MessageBase()
 6         { }
 7 
 8         public string Send()
 9         {
10             try
11             {
12                 var httpContent = this.CreateHttpClient();
13                 return WeCharBase.Post(this.requestUri, httpContent);
14             }
15             catch (Exception ex)
16             {
17                 return ex.Message;
18             }
19         }
20 
21         protected abstract HttpContent CreateHttpClient();
22     }
23 
24     public abstract class SingleMessageBase : MessageBase
25     {
26         public SingleMessageBase()
27         {
28             base.requestUri = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={0}";
29         }
30     }
31 
32     public class TextSingleMessage : SingleMessageBase
33     {
34         public string ToUser { get; set; }
35         public string TextContent { get; set; }
36 
37         public TextSingleMessage() { }
38 
39         protected override HttpContent CreateHttpClient()
40         {
41             return new StringContent(JsonConvert.SerializeObject(new
42             {
43                 touser = ToUser,
44                 msgtype = "text",
45                 text = new
46                 {
47                     content = TextContent
48                 }
49             }));
50         }
51     }

新增控制器:SingleMessageController.cs

 1     public class SingleMessageController : Controller
 2     {
 3         /// <summary>发送文本信息</summary>
 4         /// <returns></returns>
 5         public ActionResult ViewTextSingleMessage()
 6         {
 7             return View();
 8         }
 9 
10         /// <summary>发送文本信息</summary>
11         /// <returns></returns>
12         public ActionResult TextSingleMessage(string id)
13         {
14             var textSingleMessage = new TextSingleMessage()
15             {
16                 ToUser = "ombxUwMY-l-0rFyQkubkFcl4-Ggw",
17                 TextContent = id
18             };
19 
20             return Content(textSingleMessage.Send());
21         }
22     }

新增视图：ViewTextSingleMessage.cshtml

 1 <script type="text/javascript" language="javascript">
 2     $(document).ready(function () {
 3         $("#btnTextSingleMessage").click(function () {
 4             $.ajax({
 5                 type: "POST",
 6                 url: "/SingleMessage/TextSingleMessage",
 7                 data: { id: $("#txtContent").val() },
 8                 success: function (responseTest) {
 9                     $("#resultMesage").text(responseTest);
10                 }
11             });
12         });

发送图片消息

这个参数media_id可以先在基础支持里边的在线测试接口里边上传

https://mp.weixin.qq.com/debug/cgi-bin/apiinfo?t=index&type=%E5%9F%BA%E7%A1%80%E6%94%AF%E6%8C%81&form=%E5%A4%9A%E5%AA%92%E4%BD%93%E6%96%87%E4%BB%B6%E4%B8%8A%E4%BC%A0%E6%8E%A5%E5%8F%A3%20/media/upload

 

得到"media_id": "fJOxpTkVyZDnq7s21ovoeWFHSANKBZpZBBSBOwR2DlVorkRKYXDofqsNxgywL5d8"

新增图片发送类ImageSingleMessage.cs

 1     public class ImageSingleMessage : SingleMessageBase
 2     {
 3         public string ToUser { get; set; }
 4         public string MediaId { get; set; }
 5 
 6         public ImageSingleMessage() { }
 7 
 8         protected override HttpContent CreateHttpClient()
 9         {
10             return new StringContent(JsonConvert.SerializeObject(new
11             {
12                 touser = ToUser,
13                 msgtype = "image",
14                 image = new
15                 {
16                     media_id = MediaId
17                 }
18             }));
19         }
