Hyperledger Composer网络启动

composer network start实用程序用于将业务网络档案从本地磁盘部署到Hyperledger Fabric v1.0网络。在使用此命令之前，请阅读部署和更新业务网络主题。

请注意：你必须先使用composer runtime install命令将Hyperledger Composer运行时安装到Hyperledger Fabric peer节点。composer runtime install命令中指定的业务网络名称必须与composer network start命令中指定的业务网络名称相同。

composer network start -a <business-network-archive> -A <admin-name> -S adminpw -c <business-network-card> -f <name-of-admin-card>

选项

composer network start [options]
Options:
  --help                             Show help  [boolean]
  -v, --version                      Show version number  [boolean]
  --archiveFile, -a                  The business network archive file name  [string] [required]
  --loglevel, -l                     The initial loglevel to set  [choices: "INFO", "WARNING", "ERROR", "DEBUG"]
  --option, -o                       Options that are specific specific to connection. Multiple options are specified by repeating this option  [string]
  --optionsFile, -O                  A file containing options that are specific to connection  [string]
  --networkAdmin, -A                 The identity name of the business network administrator  [string]
  --networkAdminCertificateFile, -C  The certificate of the business network administrator  [string]
  --networkAdminEnrollSecret, -S     Use enrollment secret for the business network administrator  [string]
  --card, -c                         The cardname to use to start the network  [string]
  --file, -f                         File name of the card to be created  [string]

Hyperledger Fabric背书策略

--option, -o选项和--optionsFile, -O选项允许发送特定于连接的信息。Hyperledger Fabric背书策略可以通过几种方式使用-o和-O选项发送。

使用-o选项，背书策略可以作为单行JSON字符串发送，如下所示：
```
composer network start -o endorsementPolicy='{"identities": [.... }'
```
使用-o选项，背书策略可以作为文件路径发送，如下所示：
```
composer network start -o endorsementPolicyFile=/path/to/file/endorsementPolicy.json
```
在这种情况下，背书策略文件应该遵循以下格式：
```
{"identities":[...],
    "policy": {...}}
```

使用-O选项，背书策略可以作为文件路径发送，如下所示：

composer network start -O /path/to/file/options.json

在这种情况下，选项文件应该遵循以下格式：

      {"endorsementPolicy": {"Identities": [...].
          "policy: {...}"
        },
        "someOtherOption": "A Value"
      }
