在nacos创建sentinel相应的规则

流控规则示例

bash 复制代码

{
  "resource": "your_resource_name",
  "limitApp": "default",
  "grade": 1,
  "count": 10,
  "strategy": 0,
  "controlBehavior": 0,
  "clusterMode": false
}

降级规则示例

bash 复制代码

{
  "resource": "your_resource_name",
  "grade": 1,
  "count": 10,
  "timeWindow": 10,
  "minRequestAmount": 5,
  "statIntervalMs": 5000
}

系统规则示例

bash 复制代码

{
  "highestCpuUsage": 0.8,
  "highestMemoryUsage": 0.8,
  "qps": 1000
}

授权规则示例

bash 复制代码

{
  "resource": "your_resource_name",
  "limitApp": "default",
  "strategy": 0,
  "resourceMode": 0,
  "warmUpPeriodSec": 10,
  "maxQueueingTimeMs": 500
}

热点参数流控规则示例

bash 复制代码

{
  "resource": "your_resource_name",
  "paramIdx": 0,
  "count": 10,
  "grade": 1,
  "paramFlowItemList": [
    {
      "object": "param_value_1",
      "count": 5
    },
    {
      "object": "param_value_2",
      "count": 5
    }
  ]
}

网关流控规则示例

bash 复制代码

{
  "resource": "your_resource_name",
  "limitApp": "default",
  "grade": 1,
  "count": 10,
  "strategy": 0,
  "controlBehavior": 0,
  "clusterMode": false
}

API 流控规则示例

bash 复制代码

{
  "resource": "your_resource_name",
  "limitApp": "default",
  "grade": 1,
  "count": 10,
  "strategy": 0,
  "controlBehavior": 0,
  "clusterMode": false
}

注意：这是模糊流控规则，其他模糊同理

bash 复制代码

{
  "resource": "/api/**", // 匹配所有以 /api/ 开头的路径，包括 /api/user、/api/order 等
  "limitApp": "default",
  "grade": 1,
  "count": 10,
  "strategy": 0,
  "controlBehavior": 0,
  "clusterMode": false
}
