+# 通过QoS对服务进行动态控制
+
+
+QoS，全称为`Quality of Service`, 是常见于网络设备中的一个术语 ，例如在路由器中，可以通过Qos动态的调整和控制某些端口的权重，从优先的保障运行在这些端口上的服务质量。
+
+在Dubbo中，QoS这个概念被用于动态的对服务进行查询和控制。例如对获取当前提供和消费的所有服务，以及对服务进行动态的上下线，即从注册中心上进行注册和反注册操作。
+
+### QoS工作机制
+
+从Dubbo 2.5.8开始，默认引入了Qos功能，默认处于启动状态。所有的QoS功能被抽象成一个个的命令，通过执行这些命令，Qos会返回响应的结果。
+
+> Qos功能基于Netty4实现，在Dubbo 2.6.x之前的版本中，默认依赖的是Netty3，因此需要显示的添加Netty4的依赖，才能确保Netty4正常工作。如果使用http://start.dubbo.io自动生成的Dubbo应用，则无需添加额外的配置，因为已经默认加上了Netty4的依赖。
+
+Qos的工作机制如下图所示：
+
+
+
+
+
+1. 启动并监听一个端口，默认端口是22222
+2. 识别目标请求的协议是Http或者是Telnet，根据协议不同动态添加对应的处理器
+3. 针对不同的协议进行解码，解析出需要执行的命令
+4. 执行命令并返回结果
+
+### QoS命令
+
+QoS目前支持的命令包括：
+
+* help: 帮助命令，列出
+* ls: 列出当前所有的正在提供的服务，以及消费的服务
+* online: 动态将某个或全部服务向注册中心进行注册
+* offline: 动态将某个或全部服务从注册中心摘除（反注册）
+* quit: 退出当前telnet会话
+
+下面，我们具体来操作一下如何通过用QoS对服务进行动态控制。
+
+#### 通过Telnet方式访问QoS
+
+假设我们的Dubbo服务端已经启动，我们通过Telnet方式进行连接：
+
+```
+$ telnet localhost 22222
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+ ????????? ??? ?? ??????????? ??????????? ????????
+ ??? ???? ??? ??? ??? ??? ??? ??? ??? ???
+ ??? ??? ??? ??? ??? ??? ??? ??? ??? ???
+ ??? ??? ??? ??? ?????????? ?????????? ??? ???
+ ??? ??? ??? ??? ??????????? ??????????? ??? ???
+ ??? ??? ??? ??? ??? ??? ??? ??? ??? ???
+ ??? ???? ??? ??? ??? ??? ??? ??? ??? ???
+ ????????? ????????? ??????????? ??????????? ????????
+
+
+dubbo>
+```
+
+连接成功后，会出现`dubbo>`提示符，此时输入`help`命令
+
+```
+dubbo>help
++---------+----------------------------------------------------------------------------------+
+| help | help command |
++---------+----------------------------------------------------------------------------------+
+| ls | ls service |
++---------+----------------------------------------------------------------------------------+
+| offline | offline dubbo |
++---------+----------------------------------------------------------------------------------+
+| online | online dubbo |
++---------+----------------------------------------------------------------------------------+
+| quit | quit telnet console |
++---------+----------------------------------------------------------------------------------+
+
+dubbo>
+```
+
+会列出当前所有可用的命令，及相应的说明。
+
+也可以对单个命令进行help操作，可以看到该命令对应的示例
+
+```
+dubbo>help online
++--------------+----------------------------------------------------------------------------------+
+| COMMAND NAME | online |
++--------------+----------------------------------------------------------------------------------+
+| EXAMPLE | online dubbo |
+| | online xx.xx.xxx.service |
++--------------+----------------------------------------------------------------------------------+
+```
+
+通过`ls` 查看当前的服务状态
+
+```
+dubbo>ls
+As Provider side:
++------------------------------------------+---+
+| Provider Service Name |PUB|
++------------------------------------------+---+
+|org.apache.dubbo.demo.provider.DemoService| Y |
++------------------------------------------+---+
+As Consumer side:
++---------------------+---+
+|Consumer Service Name|NUM|
++---------------------+---+
+```
+
+可以看到，在服务端可以看到一个服务`org.apache.dubbo.demo.provider.DemoService`，第二列里面的`PUB=Y`代表改服务已经发布到注册中心，可供消费端进行调用。
+
+假设我们需要动态的对该服务进行下线操作，可以通过`offline`命令来完成
+
+```
+dubbo>offline org.apache.dubbo.demo.provider.DemoService
+OK
+```
+
+可以看到命令返回了OK，我们再通过ls看下当前的状态：
+
+```
+dubbo>ls
+As Provider side:
++------------------------------------------+---+
+| Provider Service Name |PUB|
++------------------------------------------+---+
+|org.apache.dubbo.demo.provider.DemoService| N |
++------------------------------------------+---+
+As Consumer side:
++---------------------+---+
+|Consumer Service Name|NUM|
++---------------------+---+
+```
+
+可以看到`org.apache.dubbo.demo.provider.DemoService`的`PUB`已经被设置成了`N`。
+
+通过`quit`命令退出当前的telnet会话：
+
+```
+dubbo>quit
+BYE!
+Connection closed by foreign host.
+```
+
+
+
+#### 通过HTTP方式访问QOS
+
+在上面的例子中，我们已经对`org.apache.dubbo.demo.provider.DemoService`进行了下线操作，下面，我们通过对Http方式对上面的服务进行注册操作：
+
+```
+$ curl -i http://localhost:22222/online?service=org.apache.dubbo.demo.provider.DemoService
+HTTP/1.1 200 OK
+Content-Type: text/plain
+Content-Length: 2
+
+OK%
+```
+
+> 注意online操作对应的参数，需要以`key=value`的形式提供，但实际上key会被忽略
+
+看到操作返回了OK，下面通过ls命令查看下当前的状态
+
+```
+$ curl -i http://localhost:22222/ls
+HTTP/1.1 200 OK
+Content-Type: text/plain
+Content-Length: 365
+
+As Provider side:
++------------------------------------------+---+
+| Provider Service Name |PUB|
++------------------------------------------+---+
+|org.apache.dubbo.demo.provider.DemoService| Y |
++------------------------------------------+---+
+As Consumer side:
++---------------------+---+
+|Consumer Service Name|NUM|
++---------------------+---+
+```
+
+可以看到服务的`PUB`状态已经变成了`Y`。
+
+
+
+### QoS相关参数说明
+
+QoS提供了一些启动参数，来对启动进行配置，他们主要包括：
+
+| 参数 | 说明 | 默认值 |
+| ------------------ | ----------------- | ------ |
+| qosEnable | 是否启动QoS | true |
+| qosPort | 启动QoS绑定的端口 | 22222 |
+| qosAcceptForeignIp | 是否允许远程访问 | false |
+
+> 注意，从2.6.4/2.7.0开始，qosAcceptForeignIp默认配置改为false，如果qosAcceptForeignIp设置为true，有可能带来安全风险，请仔细评估后再打开。
+
+QoS参数可以通过如下方式进行配置
+
+* 系统属性
+* dubbo.properties
+* XML方式
+* Spring-boot自动装配方式
+
+其中，上述方式的优先顺序为系统属性 > dubbo.properties > XML/Spring-boot自动装配方式。
+
+#### 使用系统属性方式进行配置
+
+```
+-Ddubbo.application.qos.enable=true
+-Ddubbo.application.qos.port=33333
+-Ddubbo.application.qos.accept.foreign.ip=false
+```
+
+#### 使用dubbo.properties文件进行配置
+
+在项目的`src/main/resources`目录下添加dubbo.properties文件，内容如下:
+```
+dubbo.application.qos.enable=true
+dubbo.application.qos.port=33333
+dubbo.application.qos.accept.foreign.ip=false
+```
+
+#### 使用XML方法进行配置
+
+如果要通过XML配置响应的QoS相关的参数，可以进行如下配置：
+
+```xml

+#### 使用spring-boot自动装配方式配置
+
+如果是spring-boot的应用，可以在`application.properties`或者`application.yml`上配置:
+
+```
+dubbo.application.qosEnable=true
+dubbo.application.qosPort=33333
+dubbo.application.qosAcceptForeignIp=false
+```
