【composer开发教程】从fabric启动开始，搭一个有rest-server的网页

https://lists.hyperledger.org/g/composer/message/125
开头放IBM大佬写的话，composer团队已经去做fabric的开发了。
?

启动fabric

启动和停止Hyperledger Fabric
您可以使用一组脚本控制运行时，~/fabric-dev-servers如果您遵循建议的默认值，则可以找到这些脚本。

第一次启动新运行时，您需要运行启动脚本，然后生成PeerAdmin卡：

    cd ~/fabric-dev-servers
    export FABRIC_VERSION=hlfv11
    ./startFabric.sh
    ./createPeerAdminCard.sh

这里第二句export的意思是设置启动的版本。有hlfv1、hlfv11、hlfv12.具体区别我不太记得了。

您可以使用启动和停止运行时
~/fabric-dev-servers/stopFabric.sh，
然后再次启动它
~/fabric-dev-servers/startFabric.sh。

在开发会议结束时，您运行
~/fabric-dev-servers/stopFabric.sh，
然后
~/fabric-dev-servers/teardownFabric.sh。

请注意，如果您运行拆卸脚本，则下次启动运行时时，您需要创建一个新的PeerAdmin卡，就像您第一次启动时一样。
【实验证明，teardownFabric并不会删掉你的card和链码。还是说我不明白官方的意思？这个下午我重装了images。使用的是teardownAllFabric这个脚本本】
【我必须振作起来，不能丧，不要老是讲丧气话，要给自己打气】
题外话。
要运行playground很简单。
在bash下面输入：

composer-playground

即可。
唉。
playground的作用是测试你的model、transaction还有ACL，其实还挺好的。
只需要打包成bna，之后apply到playground就可以了。
这里有点说明。
https://hyperledger.github.io/composer/v0.19/playground/playground-index

打包成bna 用

composer archive create --sourceType dir --sourceName ../
这个注意是在你的项目目录下的文件夹中。教程是把bna放在项目目录中的dist文件夹里面。bash需要进入到dist目录下再运行上面那条命令。
然后在playground里面导入bna文件，deploy即可。

NB，我docker都重新下载了啊，为啥原来的card啥的都还在啊。
迷诶。

创建project

（1）创建一个project

yo hyperledger-composer

输入这个命令，在你的工作目录下面创建一个新的项目。

cielo@cielo-ThinkPad-E550:~/cprogrames$ yo hyperledger-composer
Welcome to the Hyperledger Composer project generator
? Please select the type of project: Business Network
You can run this generator using: 'yo hyperledger-composer:businessnetwork'
Welcome to the business network generator
? Business network name: airlinev10
? Description: this is the airlinev10
? Author name:  cielo
? Author email: 手动打码
? License: Apache-2.0
? Namespace: org.acme.airline.aircraft
? Do you want to generate an empty template network? Yes: generate an empty template network
   create package.json
   create README.md
   create models/org.acme.airline.aircraft.cto
   create permissions.acl
   create .eslintrc.yml

如上，我创建了一个空的business network application。

不过你们要测试的话弄一个不空的吧。

接下来archive install start三连。

composer archive create  --sourceType dir --sourceName ../
composer network install -a ./[email protected] -c PeerAdmin@hlfv1
composer network start -n test-bna -c PeerAdmin@hlfv1 -V 0.0.2 -A admin -S adminpw

看！这个dev开头的container才是对的container！我之前生成的到底是什么！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！

都succeed之后，会随着项目生成一个admin card，在当前目录下面。
之后需要import一下这个card。

cielo@cielo-ThinkPad-E550:~/cprogrames/test-bna/dist$ composer card import -f [email protected]

Launch REST Server

composer-rest-server -c admin@airlinev8 -n always -w true
正确运行结果：

cielo@cielo-ThinkPad-E550:~/cprogrames/test-bna/dist$ composer-rest-server -c admin@test-bna -n always -w true

有angular程序的，在angular的文件夹里面 ng serve一下就ok。

成功的命令行的样子。

cielo@cielo-ThinkPad-E550:~/cprogrames/test-bna/angular-test$ ng serve

raj给的例子里面的命令

# org.acme.airline

# Airline v9

https://hyperledger.github.io/composer/reference/acl_language.html

Refer to lecture on Access Control Language
