错误:没有来自任何对等方的有效响应.执行事务失败，无法启动链代码

Question

我正在尝试运行所提供的资产转移分类账查询文件夹中的app.js文件，并稍作修改。

我对asset-transfer-ledger-chaincode.js文件进行了更改，如下所示：

async CreateAsset(ctx, assetID, color, size, owner, appraisedValue) {
const exists = await this.AssetExists(ctx, assetID);
if (exists) {
throw new Error(`The asset ${assetID} already exists`);
}
// ==== Create asset object and marshal to JSON ====
let asset = {
docType: 'asset',
assetID: assetID,
color: color,
size: size,
owner: owner,
appraisedValue: appraisedValue,
couponID: assetID,
value: color,
expiration: size,
user: sha256(owner),
uuid: uuid.v5(),
redeemed: false
};

基本上，我只是在asset对象中添加了一些属性。

更新链代码并运行node app.js后，我得到以下错误：

如果我不对链代码文件进行任何更改，它就可以正常工作。有人知道我能做什么吗？

Answer 1

我试图重现你的情况。

# fabric-samples/test-network
./network.sh down
./network.sh up createChannel -c mychannel -ca
./network.sh deployCC -ccn ledger -ccl javascript

# fabric-samples/asset-transfer-ledger-queries/application-javascript
node -v 
# v12.13.1
npm install
node app.js

您还可以在链代码容器中查看错误日志

# check <your_chaincode_container_name>
docker ps -a
# view logs
docker logs <your_chaincode_container_name> 

1.导入库[chaincode.js]

#[ERROR CODE] - `node app.js`
--> Submit Transaction: InitLedger, function creates the initial set of assets on the ledger
2020-12-10T00:53:48.061Z - error: [Transaction]: Error: No valid responses from any peers. Errors:
peer=peer0.org2.example.com:9051, status=500, message=error in simulation: transaction returned with failure: ReferenceError: sha256 is not defined
peer=peer0.org1.example.com:7051, status=500, message=error in simulation: transaction returned with failure: ReferenceError: sha256 is not defined

做吧

# asset_transfer_ledger_chaincode.js
const {Contract} = require('fabric-contract-api');
const sha256 = require('sha256');         // added
const uuid = require('uuid');             // added

# package.json
"dependencies": {
"fabric-contract-api": "^2.0.0",
"fabric-shim": "^2.0.0",    // added ','
"sha256": "^0.2.0",         // added
"uuid": "^8.3.2"            // added
}

2.修复错误的模块代码

#[ERROR CODE] - `node app.js`
--> Submit Transaction: InitLedger, function creates the initial set of assets on the ledger
2020-12-10T01:03:27.583Z - error: [Transaction]: Error: No valid responses from any peers. Errors:

uuid.v4()创建版本4(随机(UUID
uuid.v5()创建版本5(命名空间w/SHA-1(UUIDuuid.v5()需要输入参数

做吧

# asset_transfer_ledger_chaincode.js
// ==== Create asset object and marshal to JSON ====
let asset = {
docType: 'asset',
assetID: assetID,
color: color,
size: size,
owner: owner,
appraisedValue: appraisedValue,
couponID: assetID,
value: color,
expiration: size,
user: sha256(owner),
uuid: uuid.v5('Hello, World!', '1b671a64-40d5-491e-99b0-da01ff1f3341'), // modified
redeemed: false
};
