Hyperledger fabric [Hyperledger Composer]不允许尝试获取InvalidRelationship上的属性所有者-ACL问题

我在玩Hyperledger Composer时遇到了以下错误

{
  "$class": "org.property.registration.purchaseProperty",
  "propertyListing":
  "resource:org.property.registration.PropertyListing#PL001"
}

错误：不允许尝试获取InvalidRelationship上的属性所有者。由于ID为“Asset:org.property.registration.property”的集合中ID为“1003”的对象而创建的InvalidRelationship不存在；[原因=参与者'org.property.registration.User#0001'没有对资源'org.property.registration.property#1003'的'READ'访问权]

我正在尝试访问资产属性，它是另一个资产属性列表的一部分

asset Property identified by PID {
  o String PID
  o Integer marketPrice
  o DateTime regDate
  o String propertyType
  o String location
  o String status default= "Registered"
  --> User owner
} 

我正在尝试访问PropertyList资产并更改其中的property资产的状态。 （我想从其他用户发布的PropertyList中购买该属性）

我希望，根据错误消息，这似乎是一些权限问题，这是阻止我购买其他用户的财产帖子

// User can see all properties listed for sale
rule UserAccessAllSaleProperties {
    description: "Allow Users to access all properties listed for sale"
    participant: "org.property.registration.User"
    operation: ALL
    resource: "org.property.registration.PropertyListing"
    action: ALLOW
}

在这里，我想访问属性，它是PropertyList的一部分。 我正试图找到什么短ACL我可以使用。还在努力

欢迎各位提出建议

试试看

rule UserAccessAllSaleProperties {
    description: "Allow Users to access all properties listed for sale"
    participant: "org.property.registration.**"
    operation: READ
    resource: "org.property.registration.PropertyListing"
    action: ALLOW
}

这将允许所有参与者仅“读取”更适合您的应用程序的PropertyList资产。如果你介绍未来的参与者，这将是有益的。（假设用户被定义为参与者而不是资产）

我还建议将参与者文件和资产文件分开，因为您有一个大型应用程序。 像

并将它们相互导入

所以你的规则是

rule UserAccessAllSaleProperties {
    description: "Allow Users to access all properties listed for sale"
    participant: "org.property.registration.Participants.**"
    operation: READ
    resource: "org.property.registration.PropertyListing"
    action: ALLOW
}

谢谢你的回复。我已经改变了ACL，它几乎和你提到的一样，并且对我有效。

// User can see all properties listed for sale
rule UserAccessAllSaleProperties {
    description: "Allow Users to access all properties listed for sale"
    participant: "org.property.registration.User"
    operation: ALL
    resource: "org.property.registration.PropertyListing"
    action: ALLOW
}

rule UserAccessAllSaleProperties {
    description: "Allow Users to access all properties listed for sale"
    participant: "org.property.registration.**"
    operation: READ
    resource: "org.property.registration.PropertyListing"
    action: ALLOW
}

org.property.registration.Property (-> Will only contain Assets)
org.property.registration.Participants (-> Will only contain Participants)

rule UserAccessAllSaleProperties {
    description: "Allow Users to access all properties listed for sale"
    participant: "org.property.registration.Participants.**"
    operation: READ
    resource: "org.property.registration.PropertyListing"
    action: ALLOW
}
