微信 Api
特色: 支持多个 AppCode
支写了部分功能. 对应的主动方法在: WxApi/Methods 下. 可参照 微信的 API 接口文档自行扩展.
WxApi/Entities/Requests 下是被动接收到的消息(用户从微信向你的程序发送的消息/请求), 需要对应的 Handler 来处理这些请求.
WxApi/Entities/Messages 是主动或被动向用户发送的消息.
WxApi/Entities/Handlers 定义的是 Request 的处理程序基类(目前只定义了几种,可自行扩展). 这里的 Hander 不参于具体的业务处理, 所以只是个定义而已.
Example/Handlers Request 的业务处理程序,
Api 配置 （在Global 中执行该方法， IApiConfig 是存储接口，可以替换成自己的实现）
/// <summary>
/// 微信ApiClient 配置
/// </summary>
public static class WXApiConfig {
public static void Config() {
//从数据库获取配置信息
var cfgs = DependencyResolver.Current.GetService<IApiConfig>().GetConfigs()
.Select(c => new ApiConfig(c.TAG, c.APPID, c.APPSECRET, c.AESKEY, c.TOKEN));
ApiClient.Init(cfgs);
//Dispatcher 的依赖注入
RequestDispatcher.GetService = t => DependencyResolver.Current.GetService(t);
#region 注册处理程序
RequestDispatcher.Regist<TextHandler>(RequestTypes.Text);
RequestDispatcher.Regist<VoiceHandler>(RequestTypes.Voice);
RequestDispatcher.Regist<LinkHandler>(RequestTypes.Link);
RequestDispatcher.Regist<ClickHandler>(RequestTypes.Event, EventTypes.Click);
RequestDispatcher.Regist<SubscribeHandler>(RequestTypes.Event, EventTypes.Subscribe);
RequestDispatcher.Regist<UnsubscribeHandler>(RequestTypes.Event, EventTypes.Unsubscribe);
