node.js - 超级账本结构：由于缺少配置数据，网络配置无效

Question

我是超级账本结构和区块链的新手。到目前为止，我能够配置和运行超级账本结构的示例，但是当我将余额转移中的“Org1”重命名为“Hospital”并添加了一个新组织“Org3”时。我能够运行该应用程序，但是在尝试将用户注册到“医院”时，我遇到了以下问题。

出现错误“由于缺少配置数据而导致网络配置无效”->正如我从fabric-samples/balance-transfer项目中知道的那样，您需要为客户端即时设置配置设置，然后才能调用方法 loadFromConfig。

这是您可以在fabric-sample/balance-transer项目的文件config.js中找到的一些代码

var hfc = require('fabric-client');

hfc.setConfigSetting('network-connection-profile-path',path.join(__dirname, 'artifacts' ,file));//file here is your network connection profile
hfc.setConfigSetting('Org1-connection-profile-path',path.join(__dirname, 'artifacts', 'org1.yaml'));
hfc.setConfigSetting('Org2-connection-profile-path',path.join(__dirname, 'artifacts', 'org2.yaml'));

在文件helper.js 中，您将看到客户端调用方法 loadFromConfig 如下

client.loadFromConfig(hfc.getConfigSetting('network-connection-profile-path'));
