+| rules.case | array[array] | 是 | |
| 由一个或多个{var, operator, val}元素组成的列表，类似这样：{{var, operator, val}, {var,

[lua-resty-expr](https://github.com/api7/lua-resty-expr#operator-list) 的
`operator-list` 部分。 |
+| rules.actions | array[object] | 是 | |

的唯一元素的第一个子元素可以是 `return` 或 `limit-count`。 |
+| rules.actions[1].return | string | 否 | | |
直接返回到客户端。 |

+
+```shell
+curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY:
edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

+ },
+ {
+ "case":[
+ ["uri", "==", "/hello/v2/appid"]
+ ],
+ "actions":[
+ [
+ "limit-count",
+ {
+ "count":2,
+ "time_window":60,
+ "rejected_code":429

+ },
+ "upstream":{
+ "type":"roundrobin",
+ "nodes":{
+ "127.0.0.1:1980":1

+ }
+}'
+```
+
+如上，我们启用了 `workflow` 插件，如果请求与 `rules` 中的 `case` 匹配，则会执行对应的 `actions`。
+
+示例 1: 如果请求的 uri 是 `/hello/rejected`，则返回给客户端状态码 403。

+
+Here, the `workflow` Plugin is enabled on the Route. If the request matches
the `case` in the `rules`, the `actions` will be executed.
+
+Example 1: if the request uri is `/hello/rejected`, the `workflow` plugin
would return directly to the client

+HTTP/1.1 403 Forbidden

+
+Example 2: if the request uri is `/hello/v2/appid`, the `workflow` plugin
would execute the `limit-count` plugin
+
+```shell
+curl http://127.0.0.1:0080/hello/v2/appid -i

+```shell

+
+`workflow` 插件引入
[lua-resty-expr](https://github.com/api7/lua-resty-expr#operator-list)
来提供复杂的流量控制功能。
+
+## 属性
+
+| 名称 | 类型 | 必选项 | 默认值 | 有效值
| 描述 |
+| ------------- | ------ | ------ | ------------------------ |
--------------------------------------------------------------------------------------------------------------------------------------------------
| ------------- |
+| rules.case | array[array] | 是 | |
| 由一个或多个{var, operator, val}元素组成的列表，类似这样：{{var, operator, val}, {var,
operator, val}, ...}}。例如：{"arg_name", "==", "json"}，表示当前请求参数 name 是 json。这里的
var 与 Nginx 内部自身变量命名是保持一致，所以也可以使用 request_uri、host 等；对于 operator 部分，目前已支持的运算符有
==、~=、~~、>、<、in、has 和 ! 。操作符的具体用法请看
[lua-resty-expr](https://github.com/api7/lua-resty-expr#operator-list) 的
`operator-list` 部分。 |
+| rules.actions | array[object] | 是 | |
| 当 `case` 成功匹配时要执行的 `actions`。目前，`actions` 中只支持一个元素。`actions`
的唯一元素的第一个子元素可以是 `return` 或 `limit-count`。 |
+| rules.actions[1].return | string | 否 | | |
直接返回到客户端。 |
+| rules.actions[1].[2].code | integer | 否 | | | 返回给客户端的 HTTP 状态码。 |
+| rules.actions[1].limit-count | string | 否 | | | 执行 `limit-count` 插件的功能。 |
+| rules.actions[1].[2] | object | 否 | | | `limit-count` 插件的配置。 |
+
+:::note
+
+在 `rules` 中，按照 `rules` 的数组下标顺序依次匹配 `case`，如果 `case` 匹配成功，则直接执行对应的 `actions`。
+
+:::
+
+## 启用插件
+
+以下示例展示了如何在路由中启用 `workflow` 插件：
+
+```shell
+curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY:
edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

+## Description
+
+The `workflow` plugin is used to introduce
[lua-resty-expr](https://github.com/api7/lua-resty-expr#operator-list) to
provide complex traffic control features.
+
+## Attributes
+
+| Name | Type | Required | Default | Valid
values | Description |
+| ---------------------------- | ------------- | -------- | ------- |
------------ | ------------------------------------------------------------ |
+| rules.case | array[array] | True | |
| List of variables to match for filtering requests for conditional traffic
split. It is in the format `{variable operator value}`. For example,
`{"arg_name", "==", "json"}`. The variables here are consistent with Nginx
internal variables. For details on supported operators,
[lua-resty-expr](https://github.com/api7/lua-resty-expr#operator-list). |
+| rules.actions | array[object] | True | |
| The action to be performed when the case matches successfully. Currently,
only one element is supported in actions. The first child element of the
actions' only element can be `return` or `limit-count`. |
+| rules.actions[1].return | string | False | |
| Return directly to the client. |
+| rules.actions[1].[2].code | integer | False | |
| HTTP status code returned to the client. |
+| rules.actions[1].limit-count | string | False | |
| Execute the functions of the `limit-count` plugin. |
+| rules.actions[1].[2] | object | False | |
| Configuration of `limit-count` plugin, `group` is not supported. |
+
+:::note
+
+In `rules`, match `case` in order according to the index of the `rules`, and
execute `actions` directly if `case` match.
+
+:::
+
+## Enabling the Plugin
+
+You can configure the `workflow` plugin on a Route as shown below:
+
+```shell
+curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY:
edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
+{
+ "uri":"/hello/*",
+ "plugins":{
+ "workflow":{
+ "rules":[
+ {
+ "case":[
+ ["uri", "==", "/hello/rejected"]
+ ],
+ "actions":[
+ [
+ "return",
+ {"code": 403}
+ ]
+ ]
+ },
+ {
+ "case":[
+ ["uri", "==", "/hello/v2/appid"]
+ ],
+ "actions":[
+ [
+ "limit-count",
+ {
+ "count":2,
+ "time_window":60,
+ "rejected_code":429
+ }
+ ]
+ ]
+ }
+ ]
+ }
+ },
+ "upstream":{
+ "type":"roundrobin",
+ "nodes":{
+ "127.0.0.1:1980":1
+ }
+ }
+}'
+```
+
+Here, the `workflow` Plugin is enabled on the Route. If the request matches
the `case` in the `rules`, the `actions` will be executed.
+
+Example 1: if the request uri is `/hello/rejected`, the `workflow` plugin
would return directly to the client
Review Comment:
```suggestion
**Example 1: If the requested uri is `/hello/rejected`, the status code
`403` is returned to the client**

+......
+
+{"error_msg":"rejected by workflow"}
+```
+
+Example 2: if the request uri is `/hello/v2/appid`, the `workflow` plugin

+

+HTTP/1.1 429 Too Many Requests

+
+Example 3: if the request can not match any `case` in the `rules`, the
`workflow` plugin would do nothing

+
+## Disable Plugin
+
+To disable the `workflow` plugin, you can delete the corresponding JSON
configuration from the Plugin configuration. APISIX will automatically reload
and you do not have to restart for this to take effect.

+
+如上，我们启用了 `workflow` 插件，如果请求与 `rules` 中的 `case` 匹配，则会执行对应的 `actions`。
+

+HTTP/1.1 403 Forbidden
+......
+
+{"error_msg":"rejected by workflow"}
+```
+
+示例 2: 如果请求的 uri 是 `/hello/v2/appid`，则执行 `limit-count` 插件，限制请求的数量为 2，时间窗口为 60
秒，如果超过限制数量，则返回给客户端状态码 429
+
+```shell
+curl http://127.0.0.1:0080/hello/v2/appid -i
+HTTP/1.1 200 OK
+```
+

+
+```shell
+curl http://127.0.0.1:0080/hello/v2/appid -i
+HTTP/1.1 429 Too Many Requests
+```
+
+示例 3: 如果请求不能被任何 `case` 匹配，则 `workflow` 不会执行任何操作
+
+```shell
+curl http://127.0.0.1:0080/hello/fake -i
+HTTP/1.1 200 OK
+```
+
+## Disable Plugin
+
+当你需要禁用 `workflow` 插件时，可以通过以下命令删除相应的 JSON 配置，APISIX 将会自动重新加载相关配置，无需重启服务：
+
+```shell
+curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY:
