C# 封装微信的模板消息

1.先新建一个类库，以方便以后移植到其他的项目上继续使用，如何新建类库就自己去百度了哈，这里就不描述了，若有不会的朋友请留言哈。标红了的都要注意下咯。

2.先看看WxTemplate这个类文件的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WxTemplateMsg
{
    public class WxTemplate
    {
        /// <summary>
        /// 目标用户OpenId
        /// </summary>
        public string touser { get; set; }
        /// <summary>
        /// 模板ID
        /// </summary>
        public string template_id { get; set; }
        /// <summary>
        /// 模板消息顶部颜色（16进制），默认为#FF0000
        /// </summary>
        public string topcolor { get; set; }
        /// <summary>
        /// 模板跳转链接
        /// </summary>
        public string url { get; set; }
        /// <summary>
        /// 数据
        /// </summary>
        public object data { get; set; }
        public WxTemplate()
        {
            topcolor = "#FF0000";
        }
    }

    public class TemplateDataItem
    {
        /// <summary>
        /// 项目值
        /// </summary>
        public string value { get; set; }
        /// <summary>
        /// 16进制颜色代码，如：#FF0000
        /// </summary>
        public string color { get; set; }
        /// <summary>
        /// 
        /// </summary>
        /// <param name="v">value</param>
        /// <param name="c">color</param>
        public TemplateDataItem(string v, string c = "#173177")
        {
            value = v;
            color = c;
        }
    }
}

TemplateModel文件夹是放不同模板的类文件，我这里的是金额变动的微信模板消息

MemRechargeTemplate.cs文件代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WxTemplateMsg.TemplateModel
{
    public class MemRechargeTemplate
    {
        /// <summary>
        /// 标题
        /// </summary>
        public TemplateDataItem first { get; set; }
        /// <summary>
        /// 日期
        /// </summary>
        public TemplateDataItem date { get; set; }
        /// <summary>
        /// 变动金额
        /// </summary>
        public TemplateDataItem adCharge { get; set; }
        /// <summary>
        /// 
        /// </summary>
        public TemplateDataItem type { get; set; }
        /// <summary>
        /// 卡内余额
        /// </summary>
        public TemplateDataItem cashBalance { get; set; }
        /// <summary>
        /// 备注
        /// </summary>
        public TemplateDataItem remark { get; set; }
    }
}

3.怎么调用呢，看下面代码：

#region 发送模板消息 
                                WxTemplateMsg.WxTemplate wxTemp = new WxTemplateMsg.WxTemplate();
                                wxTemp.touser = openid;
                                wxTemp.template_id = template_id;
                                wxTemp.topcolor = "#FF0000";
                                wxTemp.url = "http://" + PubFunction.curParameter.strDoMain + "/mobile/member/bill.aspx";

                                MemRechargeTemplate memRecTemp = new MemRechargeTemplate();
                                memRecTemp.first = new WxTemplateMsg.TemplateDataItem(title);
                                memRecTemp.date = new WxTemplateMsg.TemplateDataItem(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));
                                memRecTemp.adCharge = new WxTemplateMsg.TemplateDataItem((dclTotalRechargeMoney).ToString("#0.00"));
                                memRecTemp.type = new WxTemplateMsg.TemplateDataItem("");
                                memRecTemp.cashBalance = new WxTemplateMsg.TemplateDataItem(modelMem.MemMoney.ToString("#0.00"));
                                memRecTemp.remark = new WxTemplateMsg.TemplateDataItem("点击“详情“立即查阅您的帐户财务记录。");
                                wxTemp.data = memRecTemp;

                                string res = PubFunction.PushTempleModel(wxTemp, access_token);
                                if (!res.Contains("ok"))
                                {
                                    //PubFunction.LogError("会员充值推送错误》" + res);//这里是把错误日志进入到数据库的表中，这个就自行补脑了哈
                                }
                                #endregion

上面的代码中有一个方法：PushTempleModel

/// <summary>
    /// 发送模板消息
    /// </summary>
    /// <returns></returns>
    public static string PushTempleModel(WxTemplateMsg.WxTemplate tm, string access_token)
    {
        string url = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=" + access_token;
        HttpRequestHelper httpRequest = new HttpRequestHelper();

        string postData = JavaScriptConvert.SerializeObject(tm);
        
        string response = httpRequest.Reqeust(url, postData);//调用HTTP通信接口提交数据  
        return response;
    }

HttpRequestHelper.cs文件的代码：

public string Reqeust(string url, string postText)
        {
            System.Net.HttpWebRequest request;
            request = (System.Net.HttpWebRequest)WebRequest.Create(url);
            //Post请求方式
            request.Method = "POST";
            // 内容类型
            request.ContentType = "application/x-www-form-urlencoded";
            //// 参数经过URL编码
            //string paraUrlCoded = System.Web.HttpUtility.UrlEncode(postText);
            byte[] payload;
            //将URL编码后的字符串转化为字节
            payload = System.Text.Encoding.UTF8.GetBytes(postText);
            //设置请求的 ContentLength 
            request.ContentLength = payload.Length;
            //获得请 求流
            System.IO.Stream writer = request.GetRequestStream();
            //将请求参数写入流
            writer.Write(payload, 0, payload.Length);
            // 关闭请求流
            writer.Close();
            System.Net.HttpWebResponse response;
            // 获得响应流
            response = (System.Net.HttpWebResponse)request.GetResponse();
            System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8);
            string responseText = reader.ReadToEnd();
            reader.Close();
            return responseText;
        }
