Hyperledger Composer权限.ACL

Question

我希望Seller看到他的账号：Seller在他的READ上有Account访问。但是我的规则不起作用。我怎样才能做到这一点？

//Sellers to have read access to Account asset
rule SellerReadAccessAccountsRecord {
description: "Allow seller read access to his Account asset"
participant(p): "org.acme.biznet.Seller"
operation: READ
resource(r): "org.acme.biznet.Account"
condition: (r.owner.getIdentifier() === p.getIdentifier())
action: ALLOW
}

Answer 1

如果你Account模型看起来像：

asset Account identified by accountId { 
o String accountId 
o String currency default="EUR" 
--> Seller owner
o Double balance default=0.0 
}

那么您当前的许可将有效。否则您的许可条件需要改变如下：

condition: (r.ownerId == p.getIdentifier())

Answer 2

//卖家具有对账户资产规则的读取权限SellerReadAccessAccountsRecord {描述：“允许卖家对其账户资产的读取权限”参与者（p）：“org.acme.biznet.Seller”操作：READ资源（r）：“org。 acme.biznet.Seller“condition：（r.getIdentifier（）== p.getIdentifier（））action：ALLOW}

Answer 3

这是我的解决方案：

//卖方拥有对自己的空气污染数据资产的读/写/更新权限

rule SellerAccessAirPollutionDataRecord {
    description: "Allow sellers read/write/update access to own air pollution data assets"
    participant(p): "org.acme.biznet.Seller"
    operation: CREATE, UPDATE, READ
    resource(r): "org.acme.biznet.AirPollutionData"
    condition: (r.owner.getIdentifier() == p.getIdentifier())
    action: ALLOW
}

//卖方可以读取销售的空气污染数据资产

rule SellerReadAccessAirPollutionDataRecord {
    description: "Allow sellers read access to sold air pollution data assets"
    participant(p): "org.acme.biznet.Seller"
    operation: READ
    resource(r): "org.acme.biznet.AirPollutionData"
    condition: (r.owner.getIdentifier() != p.getIdentifier())
    action: ALLOW
}
