公眾號消息會話開發

對於認證訂閱號，群發接口每天可成功調用1次，此次群發可選擇發送給全部用戶或某個分組；
對於認證服務號雖然開發者使用高級群發接口的每日調用限制為100次，但是用戶每月只能接收4條，無論在公眾平台網站上，還是使用接口群發，用戶每月只能接收4條群發消息，多於4條的群發將對該用戶發送失敗；
具備微信支付權限的公眾號，在使用群發接口上傳、群發圖文消息類型時，可使用<a>標簽加入外鏈；
4、開發者可以使用預覽接口校對消息樣式和排版，通過預覽接口可發送編輯好的消息給指定用戶校驗效果。

框架設計

為了簡化接口調用，Magicodes.WeChat.SDK對此進行了封裝。目前框架僅封裝了多圖文的接口調用，其他封裝類似：

多圖文接口

注意：多圖文群發時，圖片地址必須為上傳圖片素材時獲取到的微信服務器地址。

注意：在大多數情況下，建議使用WeChatApisContext來調用API，比如WeChatApisContext.Current.MenuApi.Get()。使用new Api（API實現類）的情況僅限於微信服務器事件代碼以及某些無法通過當前用戶請求獲取到TenantId的情形。

被動回復消息

在用戶給公眾號發消息后，微信服務器會將消息發到開發者預先在開發者中心設置的服務器地址（開發者需要進行消息真實性驗證），公眾號應該在5秒內做出回復，可以回復一個消息，也可以回復命令告訴微信服務器這條消息暫不回復。被動回復消息可以設置加密（在公眾平台官網的開發者中心處設置，設置后，按照消息加解密文檔來進行處理。

概要圖

被動回復流程
1. 普通消息回復流程

注意：對於普通消息，我們還可以通過編程將某些消息指向多客服來接收。

事件推送消息流程

配置

在開發之前，請務必按此步驟配置好認證服務號。

進入公眾號后台，進入【開發-基本配置】頁面。請按要求配置如圖所示的內容：

注意：如果使用的是Magicodes.WeiChat，請進入公眾號管理的公眾號設置頁面，獲得Url以及Token。

客服消息

在用戶給公眾號發消息后的48小時內，公眾號可以給用戶發送不限數量的消息，主要用於客服場景。用戶的行為會觸發事件推送，某些事件推送是支持公眾號據此發送客服消息的，詳見微信推送消息與事件說明文檔。

客服消息可以在微信在線客服平台登錄收發相關消息。

為了簡化接口調用，Magicodes.WeChat.SDK對此進行了封裝。

客服消息接口

注意：多圖文群發時，圖片地址必須為上傳圖片素材時獲取到的微信服務器地址。如果圖文數超過8，則將會無響應。

Demo

using Magicodes.WeiChat.Data;

using Magicodes.WeChat.SDK.Apis.CustomerService;

using Magicodes.WeChat.SDK.Apis.Menu;

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Newtonsoft.Json;

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Web;

using System.Web.Hosting;

using Magicodes.WeChat.SDK.Apis.CustomMessage;

namespace Magicodes.WeChat.SDK.Test.ApiTests

{

[TestClass]

public class CustomMessageApiTest : ApiTestBase

{

CustomMessageApi weChatApi = new CustomMessageApi();

public CustomMessageApiTest()

{

weChatApi.SetKey(1);

}

private string GetTestOpenId()

{

var weiChatUser = db.WeiChat_Users.FirstOrDefault(p => p.AllowTest);

if (weiChatUser != null)

return weiChatUser.OpenId;

throw new Exception("請設置測試粉絲用戶");

}

[TestMethod]

public void CustomMessageApiTest_SendTextMessage()

{

//發送文本客服消息

var result = weChatApi.SendTextMessage(new TextMessage()

{

TextContent = new TextMessage.Text()

{

Content = "Test_SendTextMessage",

Touser = GetTestOpenId()

});

if (!result.IsSuccess())

{

Assert.Fail("發送文本客服消息失敗，返回結果如下：" + result.DetailResult);

}

模板消息

在需要對用戶發送服務通知（如刷卡提醒、服務預約成功通知等）時，公眾號可以用特定內容模板，主動向用戶發送消息。

注意：模板消息僅用於公眾號向用戶發送重要的服務通知，只能用於符合其要求的服務場景中，如信用卡刷卡通知，商品購買成功通知等。不支持廣告等營銷類消息以及其它所有可能對用戶造成騷擾的消息。

使用規則

所有服務號都可以在功能->添加功能插件處看到申請模板消息功能的入口，但只有認證后的服務號才可以申請模板消息的使用權限並獲得該權限；
需要選擇公眾賬號服務所處的2個行業，每月可更改1次所選行業；
在所選擇行業的模板庫中選用已有的模板進行調用；
每個賬號可以同時使用25個模板。
當前每個賬號的模板消息的日調用上限為10萬次，單個模板沒有特殊限制。當賬號粉絲數超過10W/100W/1000W時，模板消息的日調用上限會相應提升，以公眾號MP后台開發者中心頁面中標明的數字為准。
