权限策略及示例

策略类型

系统策略

当您首次使用RAM用户登录函数计算控制台时，不仅需要通过阿里云账号给您的RAM用户添加访问函数计算的系统权限策略，也需要给RAM用户添加访问其他云服务的系统权限策略。成功授权后，您的RAM用户才可以正常访问函数计算服务及其他云产品服务。

 {
        "Statement": [
            {
                "Action": [
                    "ram:PassRole"
                ],
                "Effect": "Allow",
                "Resource": "*"
            }
        ],
        "Version": "1"
    }

自定义策略

除了函数计算默认提供的系统策略外，您也可以通过自定义策略进行更细粒度的权限管理。关于权限策略的基本信息，请参见权限策略基本元素。

{
    "Version": "1",
    "Statement": [
        {
            "Action": [
                "fc:InvokeFunction"
            ],
            "Resource": "acs:fc:cn-hangzhou:*:functions/demo",
            "Effect": "Allow"
        }
    ]
}

权限策略示例

自定义创建和获取服务以及创建和执行函数权限策略

{
	"Version": "1",
	"Statement": [{
			"Action": [
				"fc:CreateFunction",
				"fc:GetFunction",
				"fc:InvokeFunction"
			],

			"Effect": "Allow"
		},
		{
			"Action": [
				"ram:PassRole"
			],
			"Effect": "Allow",
			"Resource": "*"
		}
	]
}

    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "log:ListProject",
                "log:ListLogStore"
            ],
            "Resource": "acs:log:*:*:project/*"
        }
    ]
}

  "Statement": [
    {
      "Action": [
        "oss:ListBucket",
        "oss:GetBucketEventNotification",
        "oss:PutBucketEventNotification",
        "oss:DeleteBucketEventNotification"
      ],
      "Effect": "Allow",
      "Resource": "*"
    }
  ],
  "Version": "1"
}

    {
      "Action": "fc:UpdateFunction",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableServiceInternetAccess": "true"
        }
      }
    },
    {
      "Action": "fc:CreateFunction",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringNotEquals": {
          "fc:EnableServiceInternetAccess": "false"
        }
      }
    }
  ]
}

自定义禁止创建无法打开日志访问的服务权限策略

{
  "Version": "1",
  "Statement": [
    {
      "Action": "fc:UpdateFunction",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableServiceSLSLogging": "false"
        }
      }
    },
    {
      "Action": "fc:CreateFunction",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringNotEquals": {
          "fc:EnableServiceSLSLogging": "true"
        }
      }
    }
  ]
}

自定义禁止创建支持公网访问的触发器权限策略

{
  "Version": "1",
  "Statement": [
    {
      "Action": "fc:UpdateTrigger",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableHTTPTriggerAnonymous": "true"
        }
      }
    },
    {
      "Action": "fc:CreateTrigger",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableHTTPTriggerAnonymous": "true"
        }
      }
    }
  ]
}

自定义禁止创建匿名访问的触发器权限策略

{
  "Version": "1",
  "Statement": [
    {
      "Action": "fc:UpdateTrigger",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableHTTPTriggerAnonymous": "true"
        }
      }
    },
    {
      "Action": "fc:CreateTrigger",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableHTTPTriggerAnonymous": "true"
        }
      }
    }
  ]
}

该权限策略会禁止用户在API CreateTrigger - 创建触发器和UpdateTrigger - 更新触发器中将authType参数设置为anonymous（不需要认证），只允许设置为function（需要认证）。该限制仅适用于HTTP触发器，更多信息，请参见HTTPTriggerConfig。

如果尝试创建开启authType=anonymous的HTTP触发器，会出现403 AccessDenied报错。示例如下：

{
  "statusCode":403,
  "Code":"AccessDenied",
  "Message":"the caller is not authorized to perform 'fc:CreateTrigger' on resource 'acs:fc:xx:xx:functions/xx/triggers/xx' with condition '[fc:EnableHTTPTriggerAnonymous=true]'"
}

自定义禁止创建支持HTTP协议访问的自定义域名的权限策略

{
  "Version": "1",
  "Statement": [
    {
      "Action": "fc:CreateCustomDomain",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableCustomDomainHTTP": "true"
        }
      }
    },
    {
      "Action": "fc:UpdateCustomDomain",
      "Effect": "Deny",
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "fc:EnableCustomDomainHTTP": "true"
        }
      }
    }
  ]
}

该权限策略会禁止用户在API CreateCustomDomain - 创建自定义域名和UpdateCustomDomain - 更新自定义域名中将protocol参数设置为 HTTP或 HTTP,HTTPS，只能设置为 HTTPS。

如果尝试创建开启HTTP协议的自定义域名，会出现 403 AccessDenied 报错，示例如下：

{
  "statusCode":403,
  "Code":"AccessDenied",
  "Message":"the caller is not authorized to perform 'fc:CreateCustomDomain' on resource 'acs:fc:xxx:xxx:custom-domains/xxx' with condition '[fc:EnableCustomDomainHTTP=true]'"
}
