Fabric和Composer：

Hyperledger的Composer和Fabric到底是什么关系？

这篇文章是在冯宇Ops的“Hyperledger Composer开发流程”的基础上，增加了一些修改和补充。从而可以在最新的Fabric版本上顺利搭建和部署网络。

上周小结

Hyperledger Composer 网络要素百度脑图

Business Network Definition

在我们动手执行代码之前，先来了解一下Business Network Definition的概念。因为这个概念贯穿在这个网络系统中。BND为区块链定义了 数据模型， 交易逻辑 和 访问控制规则 。我们可以部署bna包到Fabric网络，为了生成bna，我们需要提前生成：

a set of model files
a set of JavaScript files
an Access Control file

所有的这些文件，都可以理解是对我们的网络的描述文件。网络根据我们的描述，来执行。

那我们就动手搭建，并且部署一个网络。
下面的代码执行于ubuntu系统。

Setp 1 创建一个business network应用

从命令行，创建一个新的dir，并且cd到该dir

amy@amy-wu:~/pg/sandbox/bnd$ yo hyperledger-composer:businessnetwork

Welcome to the business network generator
? Business network name: tutorial-network
? Description: Here is a hello world example

? License: Apache-2.0
? Namespace: org.example.biznet
? Do you want to generate an empty template network? No: generate a populated sample ne
twork
   create package.json
   create README.md
   create models/org.example.biznet.cto
   create permissions.acl
   create .eslintrc.yml
   create features/sample.feature
   create features/support/index.js
   create test/logic.js
   create lib/logic.js
amy@amy-wu:~/pg/sandbox/bnd$

查看刚刚的指令为了创建的文件

amy@amy-wu:~/pg/sandbox/bnd$ tree
.
└── tutorial-network
    ├── features
    │   ├── sample.feature
    │   └── support
    │       └── index.js
    ├── lib
    │   └── logic.js
    ├── models
    │   └── org.example.biznet.cto
    ├── package.json
    ├── permissions.acl
    ├── README.md
    └── test
        └── logic.js

6 directories, 8 files
amy@amy-wu:~/pg/sandbox/bnd$

Setp 2 查看 org.example.biznet.cto 和 permission.acl

org.example.biznet.cto 定义了网络里面的参与方，资产等信息

permission.acl 定义了访问权限

Setp 3 打包生成bna包

cd到 /tutorial-network 目录下

需要提前安装composer环境
参照这里

amy@amy-wu:~/pg/sandbox/bnd/tutorial-network$ composer archive create -t dir -n .


Creating Business Network Archive


Looking for package.json of Business Network Definition
    Input directory: /home/amy/pg/sandbox/bnd/tutorial-network

Found:
    Description: Here is a hello world example
    Name: tutorial-network
    Identifier: tutorial-network@0.0.1

Written Business Network Definition Archive file to 
    Output file: tutorial-network@0.0.1.bna

Command succeeded

    └── tutorial-network@0.0.1.bna 新生成的文件

6 directories, 9 files

Setp 4 部署business network

在做部署之前，先要启动一个Fabric网络。

下载fabric-dev-servers.zip

mkdir fabric-dev-servers && cd fabric-dev-servers
curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.zip

unzip fabric-dev-servers.zip

第一次启动Fabric网络的时候

cd fabric-dev-servers
./downloadFabric.sh
./startFabric.sh
./createPeerAdminCard.sh

结束的时候

./stopFabric.sh 
./teardownFabric.sh

初始化网路

amy@amy-wu:~/pg/sandbox/bnd/tutorial-network$ composer network install --card PeerAdmin@hlfv1 --archiveFile tutorial-network@0.0.1.bna


✔ Installing business network. This may take a minute...
Successfully installed business network tutorial-network, version 0.0.1

Command succeeded

查看docker containers

docker container ls

启动网络

amy@amy-wu:~/pg/sandbox/bnd/tutorial-network$ composer network start --networkName tutorial-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card

Starting business network tutorial-network at version 0.0.1
