Myvas.AspNetCore.Weixin

This solution is working around the Tencent WeChat (also known as Weixin) platform APIs, designed to streamline integration and enhance developer productivity.

微信公众平台/接口调用服务：在微信公众平台上申请服务号或订阅号后，经配置部署可提供自定义菜单、即时信息交流、微信网页授权、模板消息通知等接口调用及搭建站点。

获取配置参数 Options

微信公众平台：https://mp.weixin.qq.com

1. 开发/基本配置/公众号开发信息

   • 获取AppId，作为参数<WeixinOptions>.AppId
   • 获取AppSecret，作为参数<WeixinOptions>.AppSecret

2. 开发/基本配置/服务器配置：修改设置 | 启用

   • 在“服务器地址(URL)”中，填写地址: http://xxx.xxx/wx or https://xxx.xxx/wx，将二级虚拟路径(`"/wx"`)作为参数`.Path`
   • 在“网站Token”中，填写一串较长的随机字符串，作为参数<WeixinSiteOptions>.WebsiteToken
   • 在“消息加解密密钥EncodingAESKey”中，若空则初始化一个，作为参数<WeixinMessageProtectionOptions>.EncodingAESKey
   • 在“消息加解密方式”中，建议选择“安全模式”。其他选项有"明文模式"和"兼容模式"。当且仅当您选择"安全模式"时，将参数<WeixinMessageProtectionOptions>.StrictMode设置为true。

微信接口服务容器 WeixinBuilder

// (1.1) AddWeixinCore(...) to inject WeixinMemoryCacheProvider, IWeixinAccessTokenApi, IWeixinJsapiTicketApi, IWeixinCardTicketApi.
// (1.2) AddWeixin(...) to inject WeixinMemoryCachProvider and all APIs (see the list below).
services.AddWeixin(o => {

	o.AppSecret = Configuration["Weixin:AppSecret"];
	//o.Backchannel = _testServer.CreateClient(); // For testing using a fake TestServer
})

//(2.1) The default injection in AddWeixinCore and AddWeixin to provide a memory cache provider implemented IWeixinCacheProvider as default.
//.AddWeixinMemoryCacheProvider() 
// (2.2) To replace with a better distribution cache provider. (recommended)

• 微信接口服务注入
  • <IServiceCollection>.AddWeixin(Action<WeixinOptions>): 注入所有接口
  • <IServiceCollection>.AddWeixinCore(Action<WeixinOptions>): 注入基础会话接口
• 基础会话接口：
  • IWeixinAccessTokenApi： Usage
  • IWeixinJsapiTicketApi： Usage
  • IWeixinCardTicketApi: Usage
• 数据管理接口：
  • IWeixinUserApi:
  • IWeixinUserProfileApi:

• Cache providers:
  • Memory cache provider: AddWeixinMemoryCacheProvider (Default injected in AddWeixin(...) and AddWeixinCore(...))
  • Redis cache provider: AddWeixinRedisCacheProvider(Action<RedisCacheOptions>)
  • Customization of cache provider: AddWeixinCacheProvider<TWeixinCacheProvider> where TWeixinCacheProvider should implement IWeixinCacheProvider for IWeixinExpirableValue type.

微信公众号服务站点-中间件 WeixinSiteMiddleware

• Use the WeixinSiteMiddleware:

   app.UseWeixinSite();

• 用于搭建微信公众号服务站点

  • 接收微信公众号上行的消息和事件: Usage
  • 发送(客服)响应类消息（须有上行消息，并在48小时内回复）
  • 发送模板消息（须预先定义并申请消息模板），模板存储及管理

微信公众号服务站点-接口服务容器 WeixinSiteBuilder

• Dependency Injection: IServiceCollection

   // <WeixinBuilder>
  // (1) Add services for 
   .AddWeixinSite(o => {
   	o.Path = Configuration.GetValue("Weixin:Path", "/wx"); // optional, default is "/wx"
   	o.WebsiteToken = Configuration["Weixin:WebsiteToken"];
   	o.Debug = Configuration.GetValue<bool>("Weixin:Debug", false); // optional, default is false (Do NOT allow `微信web开发者工具(wechatdevtools)` and other browsers to access)
   })
  
   // (2) 上下行消息加解密
   .AddMessageProtection(o => {
   	o.EncodingAESKey = Configuration["Weixin:EncodingAESKey"];    
   	o.StrictMode = Configuration.GetValue<bool>("Weixin:StrictMode", false); // default is false (compatible with ClearText)
   	// (1) 若填写错误，将导致您在启用“兼容模式”或“安全模式”时无法正确解密（及加密）；
   	// (2) 若您使用“微信公众平台测试号”部署，您应当注意到其不支持消息加解密，此时须用空字符串或不配置。
   })
  
  // (3.1) The default injection in AddWeixinSite to provide a debug output on received Weixin messages and events.
  //.AddWeixinDebugEventSink() 
  
  // (3.2) To replace with an implementation with persistance in database. 
   // 自动存储上行消息及事件
   .AddWeixinEfCore<TWeixinDbContext>(o => {
   	// 启用订阅者名单同步服务
   	o.EnableSyncForWeixinSubscribers = true; // default is false
   	// 执行同步服务的时间间隔
   	o.SyncIntervalInMinutesForWeixinSubscribers = 10; // min is 3 minutes
   })
   // 使用自定义数据类型
   //.AddWeixinEfCore<TWeixinDbContext, TWeixinSubscriber>(o => ...)
   //.AddWeixinEfCore<TWeixinDbContext, TWeixinSubscriber, TKey>(o => ...)
  
  // (3.3) Or, replace with your implementation of IWeixinEventSink.
  //.AddWeixinEventSink<TWeixinCacheProvider>()
  
   // (4) 接口服务：发送客服响应消息
   .AddWeixinPassiveResponseMessaging(o => {
   	o.TrySmsOnFailed = true; // default is false
   })
  
   // (5) 接口服务：发送模板消息
   .AddWeixinTemplateMessaging(o => {
   	o.MaxRetryTimes = 5; // default is 3
   });
