5. 测试fabric-sdk-node应用
从零到壹构建基于fabric-sdk-node的项目开发实战之五
运行示例程序
一切就绪，现在可以开始测试我们的应用程序了。
终端窗口 1
-
进入项目根目录：
$ cd $HOME/kevin-fabric-sdk-node -
使用 docker-compose 命令启动网络
$ docker-compose -f artifacts/docker-compose.yaml up
终端窗口 2
-
进入项目根目录，安装
gulp：$ cd $HOME/kevin-fabric-sdk-node $ npm install -g gulp -
安装
fabric-client与fabric-ca-client模块$ npm install执行成功如下信息：
-
启动 node app 指定 PORT 为 4000
$ PORT=4000 node app启动成功如下图所示：
终端窗口 3
- 执行 REST APIs 参见 REST APIs 调用请求
REST APIs 调用请求
登录请求
在终端窗口3中执行：
$ cd $HOME/kevin-fabric-sdk-node
- 在 Org1 组织中注册并登记一个新的用户:
$ curl -s -X POST \
http://localhost:4000/users \
-H "content-type: application/x-www-form-urlencoded" \
-d 'username=Jim&orgName=Org1'
如果出现502错误，那么使用
unset http_proxy取消/关闭代理即可。
终端输出如下响应信息:
{
"success": true,
"secret": "RaxhMgevgJcm",
"message": "Jim enrolled Successfully",
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NDExNTc2OTUsInVzZXJuYW1lIjoiSmltIiwib3JnTmFtZSI6Ik9yZzEiLCJpYXQiOjE1NDExMjE2OTV9.TqN-T3xQOCkPf_HYAxd21RbmZ7FAOjcPyXadzVrfWYs"
}
注意：响应信息包含成功/失败的状态，注册密钥和JSON Web令牌（JWT），它是后续请求的请求标头中的所必需字符串
创建通道请求
$ curl -s -X POST \
http://localhost:4000/channels \
-H "authorization: Bearer " \
-H "content-type: application/json" \
-d '{
"channelName":"kevinkongyixueyuan",
"channelConfigPath":"../artifacts/channel/mychannel.tx"
}'
请注意，Header 授权必须包含POST /users通话中返回的 JWT
执行成功终端输出如下响应信息：
{
"success":true,
"message":"Channel 'kevinkongyixueyuan' created Successfully"
}
加入通道请求
$ curl -s -X POST \
http://localhost:4000/channels/kevinkongyixueyuan/peers \
-H "authorization: Bearer " \
-H "content-type: application/json" \
-d '{
"peers": ["peer0.org1.kevin.kongyixueyuan.com","peer1.org1.kevin.kongyixueyuan.com"]
}'
执行成功终端输出如下响应信息：
{
"success":true,
"message":"Successfully joined peers in organization Org1 to the channel:kevinkongyixueyuan"
}

$ curl -s -X POST \
http://localhost:4000/chaincodes \
-H "authorization: Bearer " \
-H "content-type: application/json" \
-d '{
"peers": ["peer0.org1.kevin.kongyixueyuan.com","peer1.org1.kevin.kongyixueyuan.com"],
"chaincodeName":"mycc",
"chaincodePath":"github.com/example_cc",
"chaincodeType": "golang",
"chaincodeVersion":"v0"
}'
注意： 当使用node.js链代码时，必须将chaincodeType设置为node，并且必须将chaincodePath设置为node.js chaincode的位置。也加入了$PWD
如下: $ curl -s -X POST \ http://localhost:4000/chaincodes \ -H "authorization: Bearer" \ -H "content-type: application/json" \ -d '{ "peers": ["peer0.org1.kevin.kongyixueyuan.com","peer1.org1.kevin.kongyixueyuan.com"], "chaincodeName":"mycc", "chaincodePath":"$PWD/artifacts/src/github.com/example_cc/node", "chaincodeType": "node", "chaincodeVersion":"v0" }'
执行成功终端输出如下响应信息：
{
"success":true,
"message":"Successfully install chaincode"
}

发现IP地址
要检索某个网络实体的IP地址，请使用如下命令：
# this will return the IP Address for peer0
$ docker inspect peer0 | grep IPAddress
关闭并清理网络
创建清理网络的脚本文件：
$ cd $HOME/kevin-fabric-sdk-node
$ vim shutdownnetwork.sh
文件中添加如下内容：
echo "shutdown fabric-network"
echo
docker-compose -f artifacts/docker-compose.yaml down
echo
echo "docker rm -f $(docker ps -aq)"
echo
docker rm -f $(docker ps -aq)
echo
echo "docker rmi -f $(docker images | grep dev | awk '{print $3}')"
echo
docker rmi -f $(docker images | grep dev | awk '{print $3}')
echo
echo "Delete current dir org-kv"
echo
rm -rf fabric-client-kv-org[1-2]
echo
echo "Delete tmp dir org-kv"
echo
rm -rf /tmp/fabric-client-kv-org[1-2]
echo
echo "shutdown and clear OK"
添加可执行权限并执行：
$ chmod 777 ./shutdownnetwork.sh
$ ./shutdownnetwork.sh
