Hyperledger fabric Hyperledger结构：频道上未知的服务订购者.AtomicBroadcast.sendTransaction（）

我是fabric世界的新手，正在fabric 1.4中测试Java SDK
我已经通过VisualStudio代码和fabric local env建立了一个智能合约
现在，我想通过Java调用智能合约端点与之交互

private Optional<FileAsset> sendTransaction(HFClient client, String functionToCall, String... args) {
    Channel channel = client.getChannel(channelName);

    TransactionProposalRequest tpr = TransactionProposalRequest.newInstance(client.getUserContext());

    ChaincodeID fileChainCCId = ChaincodeID
            .newBuilder()
            .setName(chaincodeName)
            .setVersion(chaincodeVersion)
            .build();

    tpr.setChaincodeID(fileChainCCId);
    tpr.setChaincodeLanguage(Type.NODE);
    tpr.setFcn(functionToCall).setArgs(args);
    tpr.setProposalWaitTime(6_000);

    log.info("Calling function: {} with args: {}", functionToCall, args);



    Map<String, byte[]> tm2 = new HashMap<>();
    tm2.put("HyperLedgerFabric", "TransactionProposalRequest:JavaSDK".getBytes(UTF_8)); // Just

    tm2.put("method", "TransactionProposalRequest".getBytes(UTF_8)); // ditto
    tm2.put("result", ":)".getBytes(UTF_8)); // This should be returned in
                                                // the payload see chaincode
                                                // why.

    tm2.put(EXPECTED_EVENT_NAME, EXPECTED_EVENT_DATA); // This should
                                                        // trigger an event
                                                        // see chaincode
                                                        // why.

    try {
        tpr.setTransientMap(tm2);
    } catch (InvalidArgumentException e) {
        log.error("Error setting transient map. Err: {}", e.getMessage());
        return Optional.empty();
    }

    Collection<ProposalResponse> responses = null;

    try {
        responses = channel.sendTransactionProposal(tpr, channel.getPeers());

    } catch (ProposalException | InvalidArgumentException e) {
        log.error("Error sending transaction proposal: {}. Err: {}", tpr, e.getMessage());
        return Optional.empty();
    }

    List<ProposalResponse> invalid = responses.stream().filter(r -> r.isInvalid()).collect(Collectors.toList());
    if (!invalid.isEmpty()) {
        invalid.forEach(response -> {
            log.error(response.getMessage());
        });
        return Optional.empty();
    }

    List<ProposalResponse> resps = responses.stream()
            .filter(r -> r.getStatus().equals(ProposalResponse.Status.SUCCESS)).collect(Collectors.toList());

    resps.stream().forEach(resp -> {
        log.info("Successful transaction proposal response Txid: {} from peer {}", resp.getTransactionID(),
                resp.getPeer().getName());
    });

    try {
        Collection<Set<ProposalResponse>> proposalConsistencySets = SDKUtils.getProposalConsistencySets(responses);
        if (proposalConsistencySets.size() != 1) {
            log.error("Expected only one set of consistent proposal responses but got {}",
                    proposalConsistencySets.size());
            return Optional.empty();
        }
    } catch (InvalidArgumentException e) {
        log.error("Error generating proposal consistency sets. Err: {}", e.getMessage());
        return Optional.empty();
    }

    // If all responses are fine, then we can proceed with sending the
    // transaction to an orderer

    CompletableFuture<TransactionEvent> sentTransaction = channel.sendTransaction(resps, channel.getOrderers(), client.getUserContext());

    // For simplicity, we just request result with a timeout and verify that
    // for validity.
    BlockEvent.TransactionEvent event = null;
    try {
        event = sentTransaction.get(60, TimeUnit.SECONDS);
    } catch (InterruptedException | ExecutionException | TimeoutException e) {
        log.error("Error sending transaction to orders. Err: {}", e.getMessage());
        return Optional.empty();
    }

    if (event.isValid()) {
        log.info("Transacion tx: " + event.getTransactionID() + " is completed.");
    } else {
        log.error("Transaction tx: " + event.getTransactionID() + " is invalid.");
    }
    return Optional.empty();
}

有关于如何解决的建议吗？

您针对的是AtomicBroadcast-peer0.org1.example.com的对等方

您需要以订购者为目标。似乎您的网络配置是错误的。

我使用的是来自IBM区块链平台的网络配置：一个ca、一个对等方、一个订购方。[
