现在可以将 composer Fabric 业务网络、.bna 文件部署到 bluemix 区块链服务吗？如果是这样，是否有某人可以共享的连接配置文件示例？谢谢。

您现在可以将 Composer 与 Bluemix 区块链服务一起使用。

但是，您必须运行 Composer Playground 的本地副本，因为在 Bluemix (fabric-composer.mybluemix.net) 上运行的 Composer 版本目前仅支持 Web 连接配置文件。

您可以按照此处的说明设置 Composer Playground 的本地副本：https ://fabric-composer.github.io/start/getting-started-playground.html

这是我用来连接到 Bluemix Blockchain 服务的连接配置文件：

URL 中的主机名和端口号必须来自 Bluemix 仪表板。我发现通过导航到“服务凭据”并查看默认凭据“Credentials-1”最容易获取此信息。以下是每个 URL 来自何处的说明：

membersServicesURL始终是来自“ca”对象的“grpcs://”+ url（url 也是 discovery_host + “:” + discovery_port）。

peerURL始终是 "grpcs://" + discovery_host + ":" + discovery_port 来自 "peers" 数组中列出的对等点之一。

eventHubURL始终是 "grpcs://" + event_host + ":" + event_port 来自 "peers" 数组中列出的对等点之一。

keyValStore是运行 Composer 的系统的文件系统上的一个目录。如果使用 Docker 映像，则使用“/home/composer/.composer-credentials”路径，否则使用您机器上存在的目录。

证书来自“us.blockchain.ibm.com.cert”文件，该文件可以从凭证中的“cert”属性下载，例如“ https://blockchain-certs.mybluemix.net/us.blockchain.ibm .com.cert ”。如果您手动创建此 JSON，则必须确保它以“\n”换行符结尾。

certificatePath来自凭证中的“cert_path”属性。

您还可以从凭证页面获取用于 Bluemix 的注册 ID 和注册密码；我建议使用“管理员”。请注意，如果您使用 REST API 与 Bluemix 服务交互，那么您不能将这些相同的凭证用于 Composer。

但是需要注意的一点是，Bluemix 区块链服务可能不可靠，因为事件中心连接因不活动而超时。发生这种情况时，Composer 将终止，您可能会看到一个错误。我们正在等待对 hfc（Hyperledger Fabric 客户端）Node.js 模块的修复，该模块将正确处理此错误并根据需要重新连接。

希望有帮助，

西蒙
