ENDORSEMENT_POLICY_FAILURE 在私有数据的情况下在 hyperledger fabric 中

Question

我们正在开展一个项目，我们在其中使用最新的私人数据收集。我们是运行 kubernetes 设置中的同行。我们有一个如下所述的集合配置，

 {
    "name": "Org1_PDC2",
    "policy": "OR ('Org1.member')",
    "requiredPeerCount": 0,
    "maxPeerCount": 2,
    "memberOnlyRead": true,
    "memberOnlyWrite": true,
    "blockToLive": 0,
    "endorsementPolicy": {
       "signaturePolicy": "OR('Org1.member')"
     }
  }

我们在频道中有 2 个组织，每个组织有 2 个同行。由于我们已经提到了“Org1_PDC2”的背书策略只需要来自 Org1 的签名。但我们看到交易也发送到 Org2 的 peer1。但它在 org2 中失败，因为它无法访问“Org1_PDC2”。我们还从 nodejs 应用程序观察到，当我们提交交易时，它给了我们一个 endorsementPolicy Failure 并且我可以在 Org1 的 peer1 日志中看到链码执行成功但是在 Org1 日志的 peer2 中我看到错误为

] channel=mychannel

我们在 nodejs 应用程序中使用发现选项，选项为

await gateway.connect(connectionProfile, {discovery: { enabled: true, asLocalhost: false}});
const network = await gateway.getNetwork('mychannel');
const contract = await network.getContract(contractName);

并且在org1客户端的连接配置文件中，我们只保留了org1和orderer的peer信息。我们从客户端调用任何事务时得到的错误消息是

[TransactionEventHandler]: strategyFail: commit failure for transaction "e7080f63ff9be02002d2723b7431b1e9f236c8119c7c37e7dd21bf924a8a5b7a": TransactionError: Commit of transaction e7080f63ff9be02002d2723b7431b1e9f236c8119c7c37e7dd21bf924a8a5b7a failed on peer peer1.org1.svc.cluster.local with status ENDORSEMENT_POLICY_FAILURE

在使用该合约调用交易之前，您可能需要让客户端 SDK 了解链代码使用 contract.addDiscoveryInterest() 访问的集合，如本教程页面所述：

如果不成功，您可以使用transaction.setEndorsingOrganizations()明确设置用于背书的组织：
