我正在使用 Fabric SDK Go 將私有數據添加到 Hyperledger 中，但在調用數據時出現錯誤。實例化鏈碼ccPolicy, err := cauthdsl.FromString("AND ('Org1MSP.member','Org2MSP.member')")resMgmt.InstantiateCC( setup.Org.ChannelID, resmgmt.InstantiateCCRequest{ Name: chaincodeId, Path: setup.Org.ChaincodePath, Version: chaincodeVersion, Args: [][]byte{[]byte("init")}, Policy: ccPolicy, },resmgmt.WithRetry(retry.DefaultResMgmtOpts))集合配置.json[ { "name": "collectionMedium", "policy": "AND ('Org1MSP.member', 'Org2MSP.member')", "requiredPeerCount": 0, "maxPeerCount": 3, "blockToLive":1000000 }, { "name": "collectionPrivate", "policy": "OR('Org2MSP.member')", "requiredPeerCount": 0, "maxPeerCount": 3, "blockToLive":5 }]調用product := &model.Product{id, name, color, length, width}productBytes, err1 := json.Marshal(product)if err1 != nil { return shim.Error(err1.Error())} err2 := stub.PutPrivateData("collectionMedium", id, productBytes)if err2 != nil { return shim.Error(err2.Error())}錯誤Chaincode status Code: (500) UNKNOWN. Description: PUT_STATE failed: collection config not defined for chaincode [CC_ORG_V00], pass the collection configuration upon chaincode definition/instantiation因此，它表示在鏈碼實例化期間未定義集合配置。但是，我不知道如何在鏈代碼實例化請求中添加集合配置。請建議我解決方案。

我能夠通過以下方式創建 CollConfig 請求，并能夠將集合配置添加到我的鏈代碼實例化中。
我的解決方案
#CollConfig 1
var collCfg1RequiredPeerCount, collCfg1MaximumPeerCount int32
var collCfg1BlockToLive uint64
collCfg1Name := "collectionMedium"
collCfg1BlockToLive = 1000
collCfg1RequiredPeerCount = 0
collCfg1MaximumPeerCount = 3
collCfg1Policy := "OR('Org1MSP.member','Org2MSP.member')"
collCfg1, err := newCollectionConfig(collCfg1Name,collCfg1Policy, collCfg1RequiredPeerCount,collCfg1MaximumPeerCount,collCfg1BlockToLive)
if err != nil {
return errors.WithMessage(err, "failed to create collection config 1")
}
#CollConfig 2
var collCfg2RequiredPeerCount, collCfg2MaximumPeerCount int32
var collCfg2BlockToLive uint64
collCfg2Name := "collectionPrivate"
collCfg2BlockToLive = 100
collCfg2RequiredPeerCount = 0
collCfg2MaximumPeerCount = 3
collCfg2Policy := "OR('Org2MSP.member')"
collCfg2, err := newCollectionConfig(collCfg2Name,collCfg2Policy, collCfg2RequiredPeerCount,collCfg2MaximumPeerCount,collCfg2BlockToLive)
if err != nil {
return errors.WithMessage(err, "failed to create collection config 1")
}
# 實例化鏈碼
cfg := []*cb.CollectionConfig{collCfg1,collCfg2}
resp, err := resMgmt.InstantiateCC(
setup.Org.ChannelID,
resmgmt.InstantiateCCRequest{
Name: chaincodeId,
Path: setup.Org.ChaincodePath,
Version: chaincodeVersion,
Args: [][]byte{[]byte("init")},
Policy: ccPolicy,
CollConfig: cfg,
},resmgmt.WithRetry(retry.DefaultResMgmtOpts))
#CollConfig 創建請求方法
func newCollectionConfig(colName, policy string, reqPeerCount, maxPeerCount int32,
blockToLive uint64) (*cb.CollectionConfig, error) {
p, err := cauthdsl.FromString(policy)
if err != nil {
return nil, err
}
cpc := &cb.CollectionPolicyConfig{
Payload: &cb.CollectionPolicyConfig_SignaturePolicy{
SignaturePolicy: p,
},
}
return &cb.CollectionConfig{
Payload: &cb.CollectionConfig_StaticCollectionConfig{
StaticCollectionConfig: &cb.StaticCollectionConfig{
Name: colName,
MemberOrgsPolicy: cpc,
RequiredPeerCount: reqPeerCount,
MaximumPeerCount: maxPeerCount,
BlockToLive: blockToLive,
},
},
}, nil }
