Hyperledger面料：背书政策三分之二同行。误差

Question

当我发出我的链码时，我会收到一条消息：

服务器返回：为ChainCodesName构造描述符失败：“mycc”：没有对等方组合可以满足认可策略

令人困惑的是，当我使用策略:和(org1msp.member)时，一切都非常清楚，并调用了我的chaincode。在本例中使用discovery命令返回服务器上的每一个对等点，非常好。但这不是我想要实现的！我想强制执行3个背书人中的2个背书。

每个对等点都在不同的机器上。下面是如何执行事务调用的示例：

Gateway.Builder builder = Gateway.createBuilder();
Wallet wallet = Wallets.newInMemoryWallet();
X509Identity ident;

try {
    ident = Identities.newX509Identity("Org1MSP",
            Identities.readX509Certificate("removed key due to security porpuse"),
            Identities.readPrivateKey("removed key due to security porpuse"));
    String userName = "admin";
    Contract contract = null;

    InputStream input = classLoader.getResourceAsStream("connection-org1.yaml");
    wallet.put("admin", ident);
    builder.identity(wallet, userName).networkConfig(input).discovery(true);
    Gateway gateway = builder.connect();
    Network network = gateway.getNetwork("crm-field-1");
    contract = network.getContract(contractName);

    byte[] response = null;
    Transaction trans = contract.createTransaction("createCrmContact");
    Map<String, byte[]> data = new HashMap<String, byte[]>();
    data.put("value", value.getBytes());
    data.putAll(initialize());
    trans = trans.setTransient(data);
    response = trans.submit(pk, fieldName);
    // response = contract.submitTransaction("createCrmContact", pk, fieldName,
    // value);
    LOGGER.error("Logging: Response - " + response);
    if (response == null)
        return null;
    return decode(response);
} catch (Exception e) {
    LOGGER.error("Logging: Error" + e.getMessage());
    e.printStackTrace();
}

于是，我自己想通了：

如果网络没有设置任何锚节点，则发现失败，因为没有endpoint，在那里他可以获得关于网络中每个节点的信息。所以把它们添加到网络上解决了我的问题。

谢谢你的建议
