使用Java SDK的Hyperledger Fabric背书策略错误

Question

我正在研究fabcar智能合约的golang版本，同时寻求实现Java-SDK API，该API注册管理员，注册用户并基于https://github.com/hyperledger/fabric-samples/tree/master/fabcar/java执行查询更新值操作

我已经成功建立了3个org-9对等点的区块链网络，在对等点上安装，实例化并调用了链码。

但是，当我正在努力实现相对API时，我只能成功查询区块链数据库，同时得到“无法满足链码mycc的认可政策”

请在下面找到相对错误的屏幕截图

认可政策为“ OR（'Org1MSP.member'，'Org2MSP.member'，'Org3MSP.member'）”。

注册用户是否应该以某种方式获得Org1 / Org2 / Org3.member属性？任何线索将不胜感激！

就像@IkarPohorský所说，对我来说，使用正确的方法名称后，此问题得到解决。另外，如果重新创建了HLF n / w，请确保删除“ wallet”文件夹，以便重新生成用户。

@Test
public void testMyMethodToBeInvoked() throws Exception {
    deleteDirectory(".\\wallet");
    EnrollAdmin.main(null);
    RegisterUser.main(null);
    // Load a file system based wallet for managing identities.
    final Path walletPath = Paths.get("wallet");
    final Wallet wallet = Wallet.createFileSystemWallet(walletPath);

    // load a CCP
    final Path networkConfigPath = Paths
            .get("C:\\sw\\hlf146-2\\fabric-samples\\first-network\\connection-org1.yaml");

    final Gateway.Builder builder = Gateway.createBuilder();
    builder.identity(wallet, "user1").networkConfig(networkConfigPath).discovery(true);

    // create a gateway connection
    try (Gateway gateway = builder.connect()) {
        final Network network = gateway.getNetwork("mychannel");
        final Contract contract = network.getContract("mycc");

        String myJSONString="{\"a\":\"b\"}";

        byte[] result;
        // Following did NOT work. Control goes directly to 'invoke' when 'submitTransaction' is done directly. 'invoke' need not be mentioned here.
        // result = contract.submitTransaction("invoke", myJSONString);

        // Following DID work. In chaincode (my chain code was Java) I had a method named 'myMethodToBeInvoked'. The chain code was written similar to https://github.com/hyperledger/fabric-samples/blob/release-1.4/chaincode/chaincode_example02/java/src/main/java/org/hyperledger/fabric/example/SimpleChaincode.java
        result = contract.submitTransaction("myMethodToBeInvoked", my);
        System.out.println(new String(result));
    }
}

编辑：另外，请记住，如果您的链码抛出errorResponse，即使这样，我们也可能会遇到此签注失败问题。因此，请检查您的链式代码是否正常运行。
