Blockchain Explorer无法查询已安装的链代码 - Hyperledger Fabric

Question

将区块链资源管理器（https://github.com/hyperledger/blockchain-explorer）连接到Composer频道。大部分都是好的，我可以浏览并调用API用于块和事务，但查询已安装的链代码失败。堆栈在下面。这里有什么建议？非常感谢！

我怀疑此Fabric错误是Fabric CA服务器（容器）无法识别您正在使用的管理员：您是否重新启动了CA服务器。

如果安装在Linux或Mac上（Hyperledger Composer目前还不支持Windows） - 您可以使用本地Fabric Blockchain Explorer设置来查询安装的Composer业务网络，如下所示：

例如（频道名称为composerchannel）：

curl -X GET "http://localhost:8080/apis/chaincodes?channel=composerchannel" -H "accept:application/json"

将返回该频道上安装的当前作曲家业务网络列表。

或部署的链代码列表：

curl -X POST  http://localhost:8080/chaincodelist -H 'cache-control: no-cache' -H 'content-type: application/json' -d ''
