公众号消息会话开发

对于认证订阅号，群发接口每天可成功调用1次，此次群发可选择发送给全部用户或某个分组；
对于认证服务号虽然开发者使用高级群发接口的每日调用限制为100次，但是用户每月只能接收4条，无论在公众平台网站上，还是使用接口群发，用户每月只能接收4条群发消息，多于4条的群发将对该用户发送失败；
具备微信支付权限的公众号，在使用群发接口上传、群发图文消息类型时，可使用<a>标签加入外链；
4、开发者可以使用预览接口校对消息样式和排版，通过预览接口可发送编辑好的消息给指定用户校验效果。

开发思路

框架设计

为了简化接口调用，Magicodes.WeChat.SDK对此进行了封装。目前框架仅封装了多图文的接口调用，其他封装类似：

多图文接口

注意：多图文群发时，图片地址必须为上传图片素材时获取到的微信服务器地址。

Demo

using System;

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Magicodes.WeChat.SDK.Apis.Material;

using System.Linq;

namespace Magicodes.WeChat.SDK.Test.ApiTests

{

[TestClass]

public class NewsApiTest : ApiTestBase

{

NewsApi api = new NewsApi();

public NewsApiTest()

{

api.SetKey(1);

}

[TestMethod]

public void NewsApiTest_GetById()

{

var testNews = db.Site_News.FirstOrDefault();

if (testNews == null)

{

Assert.Fail("没有数据！");

}

var result = api.Get(testNews.MediaId);

if (!result.IsSuccess())

{

Assert.Fail("获取多图文信息失败，返回结果如下：" + result.DetailResult);

}

[TestMethod]

public void NewsApiTest_Get()

{

var result = api.Get();

if (!result.IsSuccess())

{

Assert.Fail("获取多图文信息失败，返回结果如下：" + result.DetailResult);

}

[TestMethod]

public void NewsApiTest_Post()

{

//不能使用第三方的图片

Articles=new System.Collections.Generic.List<NewsPostModel.ArticleInfo>()

{

new NewsPostModel.ArticleInfo()

}

注意：在大多数情况下，建议使用WeChatApisContext来调用API，比如WeChatApisContext.Current.MenuApi.Get()。使用new Api（API实现类）的情况仅限于微信服务器事件代码以及某些无法通过当前用户请求获取到TenantId的情形。

被动回复消息

在用户给公众号发消息后，微信服务器会将消息发到开发者预先在开发者中心设置的服务器地址（开发者需要进行消息真实性验证），公众号应该在5秒内做出回复，可以回复一个消息，也可以回复命令告诉微信服务器这条消息暂不回复。被动回复消息可以设置加密（在公众平台官网的开发者中心处设置，设置后，按照消息加解密文档来进行处理。

概要图

被动回复流程
1. 普通消息回复流程

注意：对于普通消息，我们还可以通过编程将某些消息指向多客服来接收。

事件推送消息流程

配置

在开发之前，请务必按此步骤配置好认证服务号。

进入公众号后台，进入【开发-基本配置】页面。请按要求配置如图所示的内容：

注意：如果使用的是Magicodes.WeiChat，请进入公众号管理的公众号设置页面，获得Url以及Token。

客服消息

在用户给公众号发消息后的48小时内，公众号可以给用户发送不限数量的消息，主要用于客服场景。用户的行为会触发事件推送，某些事件推送是支持公众号据此发送客服消息的，详见微信推送消息与事件说明文档。

客服消息可以在微信在线客服平台登录收发相关消息。

}

模板消息

在需要对用户发送服务通知（如刷卡提醒、服务预约成功通知等）时，公众号可以用特定内容模板，主动向用户发送消息。

注意：模板消息仅用于公众号向用户发送重要的服务通知，只能用于符合其要求的服务场景中，如信用卡刷卡通知，商品购买成功通知等。不支持广告等营销类消息以及其它所有可能对用户造成骚扰的消息。

效果

使用规则

所有服务号都可以在功能->添加功能插件处看到申请模板消息功能的入口，但只有认证后的服务号才可以申请模板消息的使用权限并获得该权限；
需要选择公众账号服务所处的2个行业，每月可更改1次所选行业；
在所选择行业的模板库中选用已有的模板进行调用；
每个账号可以同时使用25个模板。
当前每个账号的模板消息的日调用上限为10万次，单个模板没有特殊限制。当账号粉丝数超过10W/100W/1000W时，模板消息的日调用上限会相应提升，以公众号MP后台开发者中心页面中标明的数字为准。

框架设计

为了简化接口调用，Magicodes.WeChat.SDK对此进行了封装。
