# 物件政策範例
<a name="thing-policy-examples"></a>

如果用於向 驗證的憑證 AWS IoT Core 連接到正在評估政策的物件，則下列政策允許裝置連線：

****  

```
{  
    "Version":"2012-10-17",		 	 	 
    "Statement":[
        {  
            "Effect":"Allow",
            "Action":["iot:Connect"],
            "Resource":[ "*" ],
            "Condition": {
                "Bool": {
                    "iot:Connection.Thing.IsAttached": ["true"]
            }
        }
        }
    ]
}
```

下列政策在憑證連接至具有特定物件類型的物件，且該物件的 `attributeName` 屬性具有 `attributeValue` 值時，允許裝置發佈。如需物件政策變數的詳細資訊，請參閱[物件政策變數](thing-policy-variables.md)。

****  

```
{
  "Version":"2012-10-17",		 	 	 
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "iot:Publish"
      ],
      "Resource": "arn:aws:iot:us-east-1:123456789012:topic/device/stats",
      "Condition": {
        "StringEquals": {
          "iot:Connection.Thing.Attributes[attributeName]": "attributeValue",
          "iot:Connection.Thing.ThingTypeName": "Thing_Type_Name"
        },
        "Bool": {
          "iot:Connection.Thing.IsAttached": "true"
        }
      }
    }
  ]
}
```

下列政策允許裝置發佈至以物件屬性開頭的主題。如果裝置憑證與物件沒有關聯，則無法解析此變數，並會導致存取遭拒錯誤。如需物件政策變數的詳細資訊，請參閱[物件政策變數](thing-policy-variables.md)。
