搭建RESTful API来使用Fabric Node SDK 开篇

在Balance-Transfer中，有关于Node SDK比较完备的例子。

SDK的官方文档在这里：https://fabric-sdk-node.github.io/

Balance-Transfer中的各项配置项都已经准备了，如果需要重新生成artifacts，务必在生成之后相应的修改docker-compose.yaml，network-config.yaml

启动网络

运行./runApp.sh后，得到类似的结果：

Stopping peer1.org1.example.com ... done
Stopping peer0.org1.example.com ... done
Stopping peer1.org2.example.com ... done
Stopping peer0.org2.example.com ... done
Stopping ca_peerOrg1            ... done
Stopping ca_peerOrg2            ... done
Stopping orderer.example.com    ... done
Removing peer1.org1.example.com ... done
Removing peer0.org1.example.com ... done
Removing peer1.org2.example.com ... done
Removing peer0.org2.example.com ... done
Removing ca_peerOrg1            ... done
Removing ca_peerOrg2            ... done
Removing orderer.example.com    ... done
Removing network artifacts_default

========== No containers available for deletion ==========

========== No images available for deletion ===========

Creating network "artifacts_default" with the default driver
Creating ca_peerOrg2         ... done
Creating orderer.example.com ... done
Creating ca_peerOrg1         ... done
Creating peer0.org2.example.com ... done
Creating peer0.org1.example.com ... done
Creating peer1.org1.example.com ... done
Creating peer1.org2.example.com ... done

============== node modules installed already =============

[2018-05-16 15:38:59.461] [INFO] SampleWebApp - ***************  http://localhost:4000  ******************

在新的窗口运行 docker ps，得到

执行测试

运行./testAPIs.sh ，得到如下结果：

POST request Join channel on Org1

{"success":true,"message":"Successfully joined peers in organization Org1 to the channel:mychannel"}

POST request Join channel on Org2

{"success":true,"message":"Successfully joined peers in organization Org2 to the channel:mychannel"}

POST Install chaincode on Org1

{"success":true,"message":"Successfully install chaincode"}

POST Install chaincode on Org2

主要测试了，注册用户，创建channel，Join channle，安装chaincode，初始化chaincode，调用chaincode，查询chaincode
