## README

# 基于区块链的电子病历管理系统

## 一、涉及技术
Fabric、SpringBoot、Thymeleaf、Bootstrap、Ajax、JSON、Lombok


## 二、环境说明
-[x] Ubuntu16.04 64位 [需要安装Fabric单机环境](https://blog.csdn.net/qq_36254699/article/details/104459108)
-[x] Fabric1.4.0
-[x] SpringBoot2.0.6
-[x] JDK1.8
-[x] Thymeleaf3.0.9.RELEASE
-[x] Bootstrap4.0.0

## 三、登录入口
### 系统管理员
-[x] 注册 http://localhost:8099/MedicalRecord/user/registerView

-[x] 管理链码 http://localhost:8099/MedicalRecord/user/uploadChaincodeView

### 普通用户
-[x] 登录

## 四、源码地址
### GO语言合约开发 git
https://gitee.com/hbuzzs/MedicalRecordChainCode
### Fabric SDK git
https://gitee.com/hbuzzs/FabricSDK.git
### Java SpringBoot+BootStrap档案管理 git
https://gitee.com/hbuzzs/MedicalRecord

## 五、keyValue存储设计
### 5.1 查询每个合约的所有记录
key：合约名字 value：对应合约每条记录的的ID
### 5.2 查询用户授权的档案情况
key：档案所属人ID  value：档案ID 

## 六、命令行安装区块链
### 1. 智能合约目前版本
```
ComplaintInfo 1.1
KeyTransaction 1.0
KeyValue 1.0
PatientRecord 1.1 
RecordBillTransaction 1.0
UserInfo 1.0
UserStoreTranInfo 1.0
Wallet 1.0
```

### 2. 查看已安装合约
```$xslt
peer chaincode list --installed
```

### 3. 实例化合约代码(只需要在一个节点实例化就可以)
```
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n complaintInfo -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n keyTransaction -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n patientRecord -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n recordBillTransaction -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n userStoreTranInfo -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n userInfo -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n keyValue -v 1.0 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
```
### 4. 查看已实例化的合约
```$xslt
peer chaincode list --instantiated -C mychannel
```
### 5. 触发合约
```
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n keyValue --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt -c '{"Args":["save","test","{\"key\":\"userStoreTranInfo\",\"valueA\":\"3\",\"valueB\":\"null\"}"]}'
```
### 6. 查询合约
```
peer chaincode query -C mychannel -n recordBillTransaction -c '{"Args":["queryHistory","1"]}'
```
### 7. 升级合约
```$xslt
peer chaincode upgrade -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n recordBillTransaction -v 1.2 -c '{"Args":["init"]}' -P "OR ('Org1MSP.peer')"
```
## 七、部署Fabric的坑
### 1. 提示无法加入区块
原因： 华为云服务器的bug
解决：修改/etc/resolv.conf  注释option一行
### 2. 查询历史记录为空，但是查询最新记录可以显示
云因：GO开发智能合约 因为要处理成json所以GO结构体字段名必须大写
解决：定义结构体变量这样定义：``` ValueA string   `json:"valueA"` ```
