Question

我尝试按照步骤here实例化链码。请注意，我正在使用NodeJ（并且在下面省略了我的实际令牌）：

curl -s -X POST \
  http://localhost:4000/channels/mychannel/chaincodes \
  -H "authorization: Bearer <put JSON Web Token here>" \
  -H "content-type: application/json" \
  -d '{
    "chaincodeName":"mycc",
    "chaincodeVersion":"v0",
    "chaincodeType": "node",
    "args":["a","100","b","200"]
}'

但是在运行node app的窗口中出现此错误：

[2018-11-15 00:46:54.627] [INFO] instantiate-chaincode - instantiate proposal was good
[2018-11-15 00:46:54.628] [ERROR] instantiate-chaincode - instantiate proposal was bad
[2018-11-15 00:46:54.628] [DEBUG] instantiate-chaincode - Failed to send Proposal and receive all good ProposalResponse
[2018-11-15 00:46:54.628] [ERROR] instantiate-chaincode - Failed to instantiate. cause:Failed to send Proposal and receive all good ProposalResponse
(node:73116) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 7): Error: Failed to instantiate. cause:Failed to send Proposal and receive all good ProposalResponse

我已粘贴完整日志here。谁能帮我解决这个问题？我遵循了link之前的所有步骤，没有遇到麻烦：

注册用户Jim
创建频道
将Org1中的同行加入频道
在Org1中的对等节点上安装链码

我还可以看到一个名称为dev-peer0.org1.example.com-mycc-v0的容器，它与调试日志一起显示链码是在peer0上实例化的，但是为什么它却没有在peer1上实例化呢？

docker-compose.yaml中这些端口的含义是什么？

peer0.org1.example.com:
    container_name: peer0.org1.example.com
    ports:
      - 7051:7051
      - 7053:7053


  peer1.org1.example.com:
    container_name: peer1.org1.example.com
    ports:
      - 7056:7051
      - 7058:7053

我今天再次尝试了修改，指定了如下所示的对等体：

curl -s -X POST \
  http://localhost:4000/channels/mychannel/chaincodes \
  -H "authorization: Bearer <put JSON Web Token here>" \
  -H "content-type: application/json" \
  -d '{
    "peers": ["peer1.org1.example.com"],
    "chaincodeName":"mycc",
    "chaincodeVersion":"v0",
    "chaincodeType": "node",
    "args":["a","100","b","200"]
}'

这次成功了：

{"success":true,"message":"Successfully instantiate chaincode in organization Org1 to the channel 'mychannel'"}

在节点应用程序终端中：

[2018-11-15 22:12:26.463] [INFO] instantiate-chaincode - The chaincode instantiate transaction has been committed on peer localhost:7051
[2018-11-15 22:12:26.463] [INFO] instantiate-chaincode - Transaction 979eeb030e6adf9689f39163192fbb9bcba00e6942ef4d1ea6de10d982d234fe has status of VALID in blocl 1

[2018-11-15 22:12:26.468] [INFO] instantiate-chaincode - Successfully instantiate chaincode in organization Org1 to the channel 'mychannel'

我不知道为什么它昨天失败了，今天又成功了。

今天，当我最初提出curl请求时，它也失败了，因为JWT令牌已过期。为了刷新令牌，我向/users端点发出了请求，就像我昨天注册用户一样（这次用户已经被注册了）

curl -s -X POST http://localhost:4000/users -H "content-type: application/x-www-form-urlencoded" -d 'username=Jim&orgName=Org1'

下面显示了容器：

$ docker ps --format '{{.Names}}'
dev-peer1.org1.example.com-mycc-v0
dev-peer0.org1.example.com-mycc-v0
peer1.org2.example.com
peer0.org2.example.com
peer0.org1.example.com
peer1.org1.example.com
ca_peerOrg1
ca_peerOrg2
orderer.example.com

并从实例化链码的容器中记录日志： $ docker logs -f dev-peer1.org1.example.com-mycc-v0

> example_cc@1.0.0 start /usr/local/src
> node example_cc.js "--peer.address" "peer1.org1.example.com:7052"

E1115 22:12:23.956612869      17 ssl_transport_security.cc:238] Could not get common name of subject from certificate.
========= example_cc Init =========
{ fcn: 'node', params: [ 'a', '100', 'b', '200' ] }

无法实例化余额转移应用的链码
