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

    public abstract class MessageBase
    {
        protected string requestUri;

        public MessageBase()
        { }

        public string Send()
        {
            try
            {
                var httpContent = this.CreateHttpClient();
                return WeCharBase.Post(this.requestUri, httpContent);
            }
            catch (Exception ex)
            {
                return ex.Message;
            }
        }

        protected abstract HttpContent CreateHttpClient();
    }

    public abstract class SingleMessageBase : MessageBase
    {
        public SingleMessageBase()
        {
            base.requestUri = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={0}";
        }
    }

    public class TextSingleMessage : SingleMessageBase
    {
        public string ToUser { get; set; }
        public string TextContent { get; set; }

        public TextSingleMessage() { }

        protected override HttpContent CreateHttpClient()
        {
            return new StringContent(JsonConvert.SerializeObject(new
            {
                touser = ToUser,
                msgtype = "text",
                text = new
                {
                    content = TextContent
                }
            }));
        }
    }

新增控制器:SingleMessageController.cs

    public class SingleMessageController : Controller
    {
        /// <summary>发送文本信息</summary>
        /// <returns></returns>
        public ActionResult ViewTextSingleMessage()
        {
            return View();
        }

        /// <summary>发送文本信息</summary>
        /// <returns></returns>
        public ActionResult TextSingleMessage(string id)
        {
            var textSingleMessage = new TextSingleMessage()
            {
                ToUser = "ombxUwMY-l-0rFyQkubkFcl4-Ggw",
                TextContent = id
            };

            return Content(textSingleMessage.Send());
        }
    }

新增视图：ViewTextSingleMessage.cshtml

<script type="text/javascript" language="javascript">
    $(document).ready(function () {
        $("#btnTextSingleMessage").click(function () {
            $.ajax({
                type: "POST",
                url: "/SingleMessage/TextSingleMessage",
                data: { id: $("#txtContent").val() },
                success: function (responseTest) {
                    $("#resultMesage").text(responseTest);
                }
            });
        });
    });
</script>

<table>
    <tr>
        <td>
            <div class="title">发送文本消息</div>
            <textarea id="txtContent" name="txtContent" rows="4" cols="40"></textarea>
        </td>
        <td><input class="btncss" id="btnTextSingleMessage" type="button" value=" 发送 " /></td>
        <td id="resultMesage" class="resultMesage"></td>
    </tr>

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

    public class ImageSingleMessage : SingleMessageBase
    {
        public string ToUser { get; set; }
        public string MediaId { get; set; }

        public ImageSingleMessage() { }

        protected override HttpContent CreateHttpClient()
        {
            return new StringContent(JsonConvert.SerializeObject(new
            {
                touser = ToUser,
                msgtype = "image",
                image = new
                {
                    media_id = MediaId
                }
            }));
        }
    }

修改控制器：SingleMessageController.cs

 新增下边2个方法
