我正试图通过发布身份
composer identity issue -p hlfv1 -n bonusetis -i PeerAdmin -s password -u perelluis -x true -a perelluis
但我明白了
Error: fabric-ca request register failed with errors [[{"code":0,"message":"CA 'ca_peerOrg1' does not exist"}]]
Command failed.
Command succeeded
我确实有一个名为ca_peerOrg1的CA,因为到目前为止我已经使用它了,它显示在我的docker容器中:

我是一名java开发人员,我开始学习hyperledger fabric.我正在尝试为结构节点设置进行设置.我不知道如何安装cryptogen工具.
请帮我 .
我正在研究Hyperledger-composer（V0.13）的最新版本，并建立了具有多个角色的网络，每个角色都可以调用区块链中的选定交易。我现在想查询区块链（“历史记录”）中针对特定订单（资产的定义类型）执行的所有交易。
我使用两种不同的方法来提取Historian数据，一次通过直接API访问historian.getall()，另一次通过定义的查询：
query getHistorianRecords {
description: "get all Historian records"
statement: SELECT org.hyperledger.composer.system.HistorianRecord
}
这两个查询都成功，因为它们返回了系统内的所有事务。每前：
ValidatedResource {
'$modelManager': ModelManager { modelFiles: [Object] },
'$namespace': 'org.hyperledger.composer.system',
'$type': 'HistorianRecord',
'$identifier': '0c3274475fed3703692bb7344453ab0910686905451b41d5d08ff1b032732aa1',
'$validator': ResourceValidator { options: {} },
transactionId: '0c3274475fed3703692bb7344453ab0910686905451b41d5d08ff1b032732aa1',
transactionType: 'org.acme.Z2BTestNetwork.CreateOrder',
transactionInvoked:

'$modelManager': [Object],
'$namespace': 'org.acme.Z2BTestNetwork',
'$type': 'CreateOrder',
'$identifier': '0c3274475fed3703692bb7344453ab0910686905451b41d5d08ff1b032732aa1',
'$class': 'Relationship' },
eventsEmitted: [],
transactionTimestamp: 2017-09-22T19:32:48.182Z }
我找不到和需要的是一种针对单个订单查询交易历史的方法。订单的定义（部分列出）如下：
asset Order identified by orderNumber {
o String orderNumber
o String[] items
o String status
...
o String approved …基本上我有很多问题,但我会问最需要的问题.谢谢你的帮助.
1)为什么hyperledger网络需要多个订购者节点？如果我理解正确,在节点验证事务之后,它们会将这些事务传递给orderer节点.orderer节点将对这些事务加时间戳,将它们推入块中并将该块发送回节点.节点会将该块附加到分类帐.我说得对吗？如果是的话,为什么我们需要不止一个订货人？
2)我知道我可以在网络中添加更多实体,以便他们可以执行交易并进行智能合约调用并查看我的私有区块链.但节点来自哪里？我添加它们？谁加了他们？组织只是拥有证书并将进行交易的人,但节点呢？节点必须是计算机,谁将节点带到网络？如果组织可以为其事务添加节点,为什么他们需要添加多个节点？
3)如果我建立了网络并且一切都很好,我该如何连接它？我知道我可以使用sdk或node.js客户端,但简而言之,如何连接它？使用运行区块链的计算机的IP地址或使用什么？
提前谢谢你们.请帮忙.
