Hyperledger fabric 如何在Hyperledger结构中更改频道策略

我用Hyperledger Farbic创建了网络。 加密-证书是使用configtxgen工具创建的， 因此，我创建了通道tx，其中包括：

configtxgen-profile SampleChannel-OutputCreateChangeTx./config/SampleChannel.tx-channelID SampleChannel

因此，默认情况下，管理员

"policies": {
"Admins": {
"mod_policy": "Admins",
"policy": {
  "type": 3,
  "value": {
    "rule": "MAJORITY",
    "sub_policy": "Admins"
  }
},
"version": "0"
}

我如何将

mod_policy

更改为

"policies": {
"Admins": {
"mod_policy": "Admins",
"policy": {
  "type": 3,
  "value": {
    "rule": "ANY", // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    "sub_policy": "Admins"
  }
},
"version": "0"
}

我的下一步是

configtxgen-profile SampleChannel-OutputAchorPeersUpdate./config/SampleChannel.tx-channelID SampleChannel-asOrg Org1MSP

但如何使用手动更改的SampleChannel.tx将其应用于网络

非常感谢您的帮助

策略有两种类型

• 签名策略
• 隐式元策略

签名策略

这些策略标识必须签名才能满足策略要求的特定用户

For Example:
    Policies:
      MyPolicy:
        Type: Signature
        Rule: “Org1.Peer OR Org2.Peer”

隐式元策略

隐式元策略将策略的结果聚合到配置层次结构中，配置层次结构最终由签名策略定义。它们支持默认规则，如“大多数组织管理员”。与签名策略相比，这些策略使用了不同但仍然非常简单的语法：

下面是您的答案：在创建config.tx时，请执行以下操作 变化

如果您希望更具体，而不是所有写入者，并且只希望指定特定的组织管理员。使用下面的代码段

Channel: &ChannelDefaults
    Policies:
        # Who may invoke the 'Deliver' API
        Readers:
            Type: ImplicitMeta
            Rule: "ANY Readers"
        # Who may invoke the 'Broadcast' API
        Writers:
            Type: ImplicitMeta
            Rule: "ANY Writers"
        # By default, who may modify elements at this config level
        Admins:
            Type: Signature
            Rule: "OR('Org1.admin')" 

Channel: &ChannelDefaults
    Policies:
        # Who may invoke the 'Deliver' API
        Readers:
            Type: ImplicitMeta
            Rule: "ANY Readers"
        # Who may invoke the 'Broadcast' API
        Writers:
            Type: ImplicitMeta
            Rule: "ANY Writers"
        # By default, who may modify elements at this config level
        Admins:
            Type: ImplicitMeta
            Rule: "ANY Writers"

        # Who may invoke the 'Broadcast' API

            Rule: "ANY Writers"
        # By default, who may modify elements at this config level

            Type: Signature
            Rule: "OR('Org1.admin')"
