Question

我尝试使用结构节点sdk调用Fabric v1.2的服务发现功能，但出现以下错误：

case GET_FILES : 
  return{
    ...state,
    file: action.payload
  }

但是，我完全可以确保已经实例化了链码，如果不使用OnEnableDisplay = (event) => { this.props.filesDownload(attachements_call); };

，我通常可以调用它。

这是我的服务发现代码：

我在哪里错了？在我使用service discovery.之前有一些代码：

let client = await helper.getClientForOrg(orgName);
let channel = client.newChannel(channelName);
channel.addPeer(client.getPeer("peer0.org1.example.com"));
await channel.initialize({discover:true, asLocalhost:true});

let request = {
  chaincodeId: chaincodeName,
  fcn: functionName,
  args: args,
  transientMap: transient
};
logger.debug("Make query");
let response_payloads = await channel.queryByChaincode(request);

我自己解决了。那可能是某种网络错误。

现在，我将peer1.org1.example.com，peer0.org2.example.com，peer1.org2.example.com的端口更改为8051、9051、10051、11051。根据节点sdk official doc，我设置了{{1 }}。

这是我可能适用的代码：

asLocalhost = true

希望这可以帮助其他人。
