 # Filter

 Subscriber filters are similar to ASP.NET MVC filters and are mainly used to process additional work before and after the subscriber method is executed. Such as transaction management or logging, etc.

 ## Create subscribe filter

 ### Create Filter

 Create a new filter class and inherit the `SubscribeFilter` abstract class.

 ```C#
 public class MyCapFilter: SubscribeFilter
 {
    public override void OnSubscribeExecuting(ExecutingContext context)
    {
        // before subscribe method exectuing
    }

    public override void OnSubscribeExecuted(ExecutedContext context)
    {
        // after subscribe method executed
    }

    public override void OnSubscribeException(ExceptionContext context)
    {
        // subscribe method execution exception
    }
 }
 ```

 In some scenarios, if you want to terminate the subscriber method execution, you can throw an exception in `OnSubscribeExecuting`, and choose to ignore the exception in `OnSubscribeException`.

 To ignore exceptions, you can setting `context.ExceptionHandled = true` in `ExceptionContext`


 ```C#
 public override void OnSubscribeException(ExceptionContext context)
 {
    context.ExceptionHandled = true;
 }
 ```

 ### Configuration Filter

 Use `AddSubscribeFilter<>` to add a filter.

 ```C#
 services.AddCap(opt =>
 {
    // ***
 }.AddSubscribeFilter<MyCapFilter>();
 ```

 Currently, we do not support adding multiple filters.

 The data sent by using the `ICapPublisher` interface is called `Message`.

 ## Compensating transaction

 Wiki :
 [Compensating transaction](https://en.wikipedia.org/wiki/Compensating_transaction)

 In some cases, consumers need to return the execution value to tell the publisher, so that the publisher can implement some compensation actions, usually we called message compensation.

 Usually you can notify the upstream by republishing a new message in the consumer code. CAP provides a simple way to do this. You can specify `callbackName` parameter when publishing message, usually this only applies to point-to-point consumption. The following is an example.

 For example, in an e-commerce application, the initial status of the order is pending, and the status is marked as succeeded when the product quantity is successfully deducted, otherwise it is failed.

 ```C#
 // =============  Publisher =================

 _capBus.Publish("place.order.qty.deducted", 
    contentObj: new { OrderId = 1234, ProductId = 23255, Qty = 1 }, 
    callbackName: "place.order.mark.status");    

 // publisher using `callbackName` to subscribe consumer result

 [CapSubscribe("place.order.mark.status")]
 public void MarkOrderStatus(JsonElement param)
 {
    var orderId = param.GetProperty("OrderId").GetInt32();
    var isSuccess = param.GetProperty("IsSuccess").GetBoolean();
    
    if(isSuccess){
        // mark order status to succeeded
    }
    else{
       // mark order status to failed
    }
 }

 // =============  Consumer ===================

 [CapSubscribe("place.order.qty.deducted")]
 public object DeductProductQty(JsonElement param)
 {
    var orderId = param.GetProperty("OrderId").GetInt32();
    var productId = param.GetProperty("ProductId").GetInt32();
    var qty = param.GetProperty("Qty").GetInt32();

    //business logic 

    return new { OrderId = orderId, IsSuccess = true };
 }
 ```

 ## Heterogeneous system integration

 In version 3.0+, we reconstructed the message structure. We used the Header in the message protocol in the message queue to transmit some additional information, so that we can do it in the Body without modifying or packaging the user’s original The message data format and content are sent.

 This approach is reasonable. It helps to better integrate in heterogeneous systems. Compared with previous versions, users do not need to know the message structure used inside CAP to complete the integration work.

 Now we divide the message into Header and Body for transmission.

 The data in the body is the content of the original message sent by the user, that is, the content sent by calling the Publish method. We do not perform any packaging, but send it to the message queue after serialization.

 In the Header, we need to pass some additional information so that the CAP can extract the key features for operation when the message is received.

 The following is the content that needs to be written into the header of the message when sending a message in a heterogeneous system:

 Key | DataType | Description
 -- | --| --
 cap-msg-id |  string | Message Id, Generated by snowflake algorithm, can also be guid
 cap-msg-name | string | The name of the message
 cap-msg-type | string | The type of message, `typeof(T).FullName`(not required)
 cap-senttime | string | sending time (not required)

 ### Custom headers
 To consume messages sent without CAP headers, both Kafka and RabbitMQ consumers can inject a minimal set of headers using custom headers as shown below:
 ```C#
 container.AddCap(x =>
 {
    x.UseRabbitMQ(z =>
    {
        z.ExchangeName = "TestExchange";
        z.CustomHeaders = e => new List<KeyValuePair<string, string>>
        {
            new KeyValuePair<string, string>(DotNetCore.CAP.Messages.Headers.MessageId, SnowflakeId.Default().NextId().ToString()),
            new KeyValuePair<string, string>(DotNetCore.CAP.Messages.Headers.MessageName, e.RoutingKey)
        };
    });
 });
 ```

 After adding `cap-msg-id` and `cap-msg-name`, CAP consumers receive messages sent directly from the RabbitMQ management tool.

 ## Summary

 One of the most powerful advantages of asynchronous messaging over direct integrated message queues is reliability, where failures in one part of the system do not propagate or cause the entire system to crash. Messages are stored inside the CAP to ensure the reliability of the message, and strategies such as retry are used to achieve the final consistency of data between services.

 This configuration option is used to configure the Dashboard front end to get the polling time of the status interface (/stats).

 * Authorization
 * UseAuth 

 This configuration option is used to configure the authorization filter when accessing the Dashboard. The default filter allows LAN access. When your application wants to provide external network access, you can customize authentication rules by setting this configuration. See the next section for details.
 > Default：false

 ### Custom authentication
 Enable authentication on dashboard request.

 Dashboard authentication can be customized by implementing the `IDashboardAuthorizationFilter` interface.
 * DefaultAuthenticationScheme 

 The following is a sample code that determines if access is allowed by reading the accesskey from the url request parameter.
 Default scheme used for authentication. If no scheme is set, the DefaultScheme set up in AddAuthentication will be used.

 * UseChallengeOnAuth

 > Default：false

 Enable authentication challenge on dashboard request.

 * DefaultChallengeScheme 

 Default scheme used for authentication challenge. If no scheme is set, the DefaultChallengeScheme set up in AddAuthentication will be used.

 ###  Custom authentication

 From version 5.1.0, Dashboard authorization uses ASP.NET Core style by default and no longer provides custom authorization filters.

 During Dashabord authentication, the value will be taken from `HttpContext.User?.Identity?.IsAuthenticated`. If it is not available, the authentication will fail and the `DefaultChallengeScheme` will be called (if configured).

 You can view the usage details in the sample project `Sample.Dashboard.Auth`.

 ```C#
 public class TestAuthorizationFilter : IDashboardAuthorizationFilter
 {
    public bool Authorize(DashboardContext context)
 services
    .AddAuthorization()
    .AddAuthentication(options =>
    {
        if(context.Request.GetQuery("accesskey")=="xxxxxx"){
            return true;
        }
        return false;
    }
 }
        options.DefaultScheme =  CookieAuthenticationDefaults.AuthenticationScheme;
        options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
    })
    .AddCookie()
    .AddOpenIdConnect(options =>

        options.Scope.Clear();
        options.Scope.Add("openid");
        options.Scope.Add("profile");
    })
 ```

 Then configure this filter when registration Dashboard.

 ```C#
 services.AddCap(x =>

 # NATS

 [NATS](https://nats.io/) is a simple, secure and performant communications system for digital systems, services and devices. NATS is part of the Cloud Native Computing Foundation (CNCF).

 !!! warning
    We currently implement NATS provider based on Request/Response mode, and we plan to replace it with JetStream in future version.
    see https://github.com/dotnetcore/CAP/issues/983 for more information.

 ## Configuration

 To use NATS transporter, you need to install the following package from NuGet:

 ```powershell

 PM> Install-Package DotNetCore.CAP.NATS

 ```

 Then you can add configuration items to the `ConfigureServices` method of `Startup.cs`.

 ```csharp

 public void ConfigureServices(IServiceCollection services)
 {
    services.AddCap(capOptions =>
    {
        capOptions.UseNATS(natsOptions=>{
            //NATS Options
        });
    });
 }

 ```

 #### NATS Options

 NATS configuration parameters provided directly by the CAP:

 NAME | DESCRIPTION | TYPE | DEFAULT
 :---|:---|---|:---
 Options | NATS client configuration | Options | Options
 Servers | Server url/urls used to connect to the NATs server. | string | NULL
 ConnectionPoolSize  | number of connections pool | uint | 10

 #### NATS ConfigurationOptions

 If you need **more** native NATS related configuration options, you can set them in the `Options` option:

 ```csharp
 services.AddCap(capOptions => 
 {
    capOptions.UseNATS(natsOptions=>
    {
        // NATS options.
        natsOptions.Options.Url="";
    });
 });
 ```

 # Redis Streams

 [Redis](https://redis.io/) is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker.

 [Redis Stream](https://redis.io/topics/streams-intro) is a new data type introduced with Redis 5.0, which models a log data structure in a more abstract way with an append only data structure.

 Redis Streams can be used in CAP as a message transporter. 

 ## Configuration

 To use Redis Streams transporter, you need to install the following package from NuGet:

 ```powershell
 PM> Install-Package DotNetCore.CAP.RedisStreams

 ```

 Then you can add configuration items to the `ConfigureServices` method of `Startup.cs`.

 ```csharp

 public void ConfigureServices(IServiceCollection services)
 {

    {
        capOptions.UseRedis(redisOptions=>{
            //redisOptions
        });
    });
 }

 ```

 #### Redis Streams Options

 Redis configuration parameters provided directly by the CAP:

 NAME | DESCRIPTION | TYPE | DEFAULT
 :---|:---|---|:---
 Configuration | redis connection configuration (StackExchange.Redis) | ConfigurationOptions | ConfigurationOptions
 StreamEntriesCount | number of entries returned from a stream while reading | uint | 10
 ConnectionPoolSize  | number of connections pool | uint | 10

 #### Redis ConfigurationOptions

 If you need **more** native Redis related configuration options, you can set them in the `Configuration` option:

 ```csharp
 services.AddCap(capOptions => 
 {
    capOptions.UseRedis(redisOptions=>
    {
        // redis options.

 # 过滤器

 在 5.1.0 版本中，我们支持了在订阅者中添加过滤器。在过去，我们通过对第三方 AOP 组件提供支持来做到这一点，例如我们写了一篇[博客](https://www.cnblogs.com/savorboard/p/cap-castle.html) 来描述如何在 CAP 5.0 版本中使用 Castle 来对订阅方法进行拦截，但了这种方式存在一些缺点，例如无法方便的在代理类中进行构造函数注入以及方法需要设定为 virtual 另外还有拦截器生命周期控制等问题。

 所以我们引入了对订阅者过滤器的支持，以使在某些场景（如事务处理，日志记录等）中变得容易。

 ## 自定义过滤器

 ### 添加过滤器

 创建一个过滤器类，并继承 `SubscribeFilter` 抽象类。

 ```C#
 public class MyCapFilter: SubscribeFilter
 {
    public override void OnSubscribeExecuting(ExecutingContext context)
    {
        // 订阅方法执行前
    }

    public override void OnSubscribeExecuted(ExecutedContext context)
    {
        // 订阅方法执行后
    }

    public override void OnSubscribeException(ExceptionContext context)
    {
        // 订阅方法执行异常
    }
 }
 ```

 在一些场景中，如果想终止订阅者方法执行，可以在 `OnSubscribeExecuting` 中抛出异常，并且在 `OnSubscribeException` 中选择忽略该异常。

 通过在 `ExceptionContext` 中设置 `context.ExceptionHandled = true` 来忽略异常。

 ```C#
 public override void OnSubscribeException(ExceptionContext context)
 {
    context.ExceptionHandled = true;
 }
 ```

 ### 配置过滤器

 ```C#
 services.AddCap(opt =>
 {
    // ***
 }.AddSubscribeFilter<MyCapFilter>();
 ```

 目前， 我们还不支持同时添加多个过滤器。

 ## 补偿事务

 [Compensating transaction](https://en.wikipedia.org/wiki/Compensating_transaction)

 某些情况下，消费者需要返回值以告诉发布者执行结果，以便于发布者实施一些动作，通常情况下这属于补偿范围。

 你可以在消费者执行的代码中通过重新发布一个新消息来通知上游，CAP 提供了一种简单的方式来做到这一点。 你可以在发送的时候指定 `callbackName` 来得到消费者的执行结果，通常这仅适用于点对点的消费。以下是一个示例。

 例如，在一个电商程序中，订单初始状态为 pending，当商品数量成功扣除时将状态标记为 succeeded ，否则为 failed。

 ```C#
 // =============  Publisher =================

 _capBus.Publish("place.order.qty.deducted", 
    contentObj: new { OrderId = 1234, ProductId = 23255, Qty = 1 },

 # 和 Castle DynamicProxy 集成

 Castle DynamicProxy 是一个用于在运行时动态生成轻量级.NET代理的库。代理对象允许在不修改类代码的情况下截取对对象成员的调用。可以代理类和接口，但是只能拦截虚拟成员。

 Castle.DynamicProxy 可以帮助你方便的创建代理对象，代理对象可以帮助构建灵活的应用程序体系结构，因为它允许将功能透明地添加到代码中，而无需对其进行修改。例如，可以代理一个类来添加日志记录或安全检查，而无需使代码知道已添加此功能。

 下面可以看到如何在 CAP 中集成使用 Castle.DynamicProxy。


 ## 1、安装 NuGet 包

 在 集成了 CAP 的项目中安装包，有关如何集成 CAP 的文档请看[这里](https://cap.dotnetcore.xyz/)。

 注意，`Castle.DynamicProxy` 这个包已经被废弃，请使用最新的 `Castle.Core` 包。

 ```xml
 <PackageReference Include="Castle.Core" Version="4.4.1" />
 ```

 ## 2、创建一个 Castle 切面拦截器

 可以在这里 [dynamicproxy.md](https://github.com/castleproject/Core/blob/master/docs/dynamicproxy.md) 找到相关的文档。

 下面为示例代码，继承 Castle 提供的 `IInterceptor` 接口即可：

 ```
 [Serializable]
 public class MyInterceptor : IInterceptor
 {
    public void Intercept(IInvocation invocation)
    {
        Console.WriteLine("Before target call");
        try
        {
            invocation.Proceed();
        }
        catch (Exception)
        {
            Console.WriteLine("Target threw an exception!");
            throw;
        }
        finally
        {
            Console.WriteLine("After target call");
        }
    }
 }

 ```

 拦截器此处命名为 `MyInterceptor`，你可以在其中处理你的业务逻辑，比如添加日志或其他的一些行为。

 ## 3、创建 IServiceCollection 的扩展类

 为 `IServiceCollection` 创建扩展，方面后续调用。

 ```csharp
 using Castle.DynamicProxy;

 public static class ServicesExtensions
 {
    public static void AddProxiedSingleton<TImplementation>(this IServiceCollection services)
        where TImplementation : class
    {
        services.AddSingleton(serviceProvider =>
        {
            var proxyGenerator = serviceProvider.GetRequiredService<ProxyGenerator>();
            var interceptors = serviceProvider.GetServices<IInterceptor>().ToArray();
            return proxyGenerator.CreateClassProxy<TImplementation>(interceptors);
        });
    }
 }
 ```

 此处我创建了一个 Singleton 声明周期的扩展方法，建议所有 CAP 的订阅者都创建为 Singleton 即可，因为在 CAP 内部实际执行的时候也会创建一个 scope 来执行，所以无需担心资源释放问题。


 ## 4、创建 CAP 订阅服务

 创建一个 CAP 订阅类，注意不能放在 Controller 中了。

 **注意：方法需要为虚方法 virtual，才能被 Castle 重写，别搞忘了加！！！**  

 ```cs
 public class CapSubscribeService: ICapSubscribe
 {
    [CapSubscribe("sample.rabbitmq.mysql")]
    public virtual void Subscriber(DateTime p)
    {
        Console.WriteLine($@"{DateTime.Now} Subscriber invoked, Info: {p}");
    }
 }
 ```

 ## 5、在 Startup 中集成

 ```cs
 public void ConfigureServices(IServiceCollection services)
 {
    // 添加 Castle 的代理生成器
    services.AddSingleton(new ProxyGenerator());
    
    // 添加第2步的自定义的拦截类，声明周期为
    services.AddSingleton<IInterceptor, MyInterceptor>();
    
    // 此处为上面的扩展方法， 添加 CAP 订阅 Service
    services.AddProxiedSingleton<CapSubscribeService>();
    
    services.AddCap(x =>
    {
        x.UseMySql("");
        x.UseRabbitMQ("");
        x.UseDashboard();
    });
    
    // ...
 }
 ```

 以上就完成了所有的集成工作，可以开始进行测试了，有问题欢迎到 [Github issue](https://github.com/dotnetcore/CAP/issues) 反馈。


 **注意： CAP 需要使用 5.0 + 版本，目前(2021年1月6日)只有 preview 版本。**

    Not yet.

    The purpose of CAP is that ensure consistency principle right in microservice or SOA architechtrues. The solution is based on ACID features of database, there is no sense about a single client wapper of message queue without database.

 !!! faq "If the consumer is abnormal, can I roll back the database executed sql that the producer has executed?"

    Can't roll back, CAP is the ultimate consistency solution.

    You can imagine your scenario is to call a third party payment. If you are doing a third-party payment operation, after calling Alipay's interface successfully, and your own code is wrong, will Alipay roll back? If you don't roll back, what should you do? The same is true here.

 #### Sessions

 当使用 `EnableSessions` 选项启用 sessions 后，每个发送的消息都会具有一个 session id。 要控制 seesion id 你可以在发送消息时在消息头中使用 `AzureServiceBusHeaders.SessionId` 携带它。


 ```csharp
 ICapPublisher capBus = ...;
 string yourEventName = ...;
 YourEventType yourEvent = ...;

 Dictionary<string, string> extraHeaders = new Dictionary<string, string>();
 extraHeaders.Add(AzureServiceBusHeaders.SessionId, <your-session-id>);

 capBus.Publish(yourEventName, yourEvent, extraHeaders);
 ```

 如果头中没有 session id , 那么消息 Id 仍然使用的 Message Id.

 # NATS

 [NATS](https://nats.io/)是一个简单、安全、高性能的数字系统、服务和设备通信系统。NATS 是 CNCF 的一部分。

 !!! warning
    我们当前基于 Request/Response 实现，我们计划将来版本中替换为 JetStream 。
    查看 https://github.com/dotnetcore/CAP/issues/983 了解更多。 
    
 ## 配置

 要使用NATS 传输器，你需要安装下面的NuGet包：

 ```powershell

 PM> Install-Package DotNetCore.CAP.NATS

 ```

 你可以通过在 `Startup.cs` 文件中配置 `ConfigureServices` 来添加配置：

 ```csharp

 public void ConfigureServices(IServiceCollection services)
 {
    services.AddCap(capOptions =>
    {
        capOptions.UseNATS(natsOptions=>{
            //NATS Options
        });
    });
 }

 ```

 #### NATS 配置

 CAP 直接提供的关于 NATS 的配置参数：


 NAME | DESCRIPTION | TYPE | DEFAULT
 :---|:---|---|:---
 Options | NATS 客户端配置 | Options | Options
 Servers | 服务器Urls地址 | string | NULL
 ConnectionPoolSize  | 连接池数量 | uint | 10

 #### NATS ConfigurationOptions

 如果你需要 **更多** 原生相关的配置项，可以通过 `Options` 配置项进行设定：

 ```csharp
 services.AddCap(capOptions => 
 {
    capOptions.UseNATS(natsOptions=>
    {
        // NATS options.
        natsOptions.Options.Url="";
    });
 });
 ```

 `Options` 是 NATS.Client 客户端提供的配置， 你可以在这个[链接](http://nats-io.github.io/nats.net/class_n_a_t_s_1_1_client_1_1_options.html)找到更多详细信息。

 ```

 #### CustomHeaders Options

 当需要从异构系统或者直接接收从RabbitMQ 控制台发送的消息时，由于 CAP 需要定义额外的头信息才能正常订阅，所以此时会出现异常。通过提供此参数来进行自定义头信息的设置来使订阅者正常工作。

 你可以在这里找到有关 [头信息](../cap/messaging#异构系统集成) 的说明。

 用法如下：

 ```cs
 x.UseRabbitMQ(aa =>
 {
    aa.CustomHeaders = e => new List<KeyValuePair<string, string>>
    {
        new KeyValuePair<string, string>(Headers.MessageId, SnowflakeId.Default().NextId().ToString()),
        new KeyValuePair<string, string>(Headers.MessageName, e.RoutingKey),
    };
 });
 ```

 # Redis Streams

 [Redis](https://redis.io/) 是一个开源（BSD许可）的，内存中的数据结构存储系统，它可以用作数据库、缓存和消息中间件。

 [Redis Stream](https://redis.io/topics/streams-intro) 是 Redis 5.0 引入的一种新数据类型，它用一种仅附加的数据结构以更抽象的方式模拟日志数据结构。

 Redis Streams 可以在 CAP 中用作消息传输器。 

 ## 配置

 要使用 Redis Streams 传输器，您需要从 NuGet 安装以下包：

 ```powershell
 PM> Install-Package DotNetCore.CAP.RedisStreams
 ```

 然后，您可以在 `Startup.cs` 的 `ConfigureServices` 方法中添加基于 Redis Stream 的配置项。 

 ```csharp

 public void ConfigureServices(IServiceCollection services)
 {
    services.AddCap(capOptions =>
    {
        capOptions.UseRedis(redisOptions=>{
            //redisOptions
        });
    });
 }

 ```

 #### Redis Streams Options

 CAP 直接对外提供的 Redis Stream 配置参数如下：

 NAME | DESCRIPTION | TYPE | DEFAULT
 :---|:---|---|:---
 Configuration | redis连接配置 (StackExchange.Redis) | ConfigurationOptions | ConfigurationOptions
 StreamEntriesCount | 读取时从 stream 返回的条目数  | uint | 10
 ConnectionPoolSize  | 连接池数  | uint | 10

 #### Redis ConfigurationOptions

 如果需要**更多**原生Redis相关配置选项，您可以在 `Configuration` 选项中进行设置 :

 ```csharp
 services.AddCap(capOptions => 
 {
    capOptions.UseRedis(redisOptions=>
    {
        // redis options.
        redisOptions.Configuration.EndPoints.Add(IPAddress.Loopback, 0);
    });
 });
 ```

 `Configuration` 是 StackExchange.Redis ConfigurationOptions ，您可以通过此[链接](https://stackexchange.github.io/StackExchange.Redis/Configuration)找到更多详细信息。
