Question

有人可以帮助我解决以下超时问题，同时实例化结构样本的一部分的余额转移应用程序的链码操作吗？

Answer 1

文档中存在问题。

实例化命令的JSON有效负载缺少“对等”定义。应该是：

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": ["peer0.org1.example.com","peer1.org1.example.com"],
    "chaincodeName":"mycc",
    "chaincodeVersion":"v0",
    "chaincodeType": "golang",
    "args":["a","100","b","200"]
}'

Answer 2

通常，实例化将花费更多时间执行，您可以在代码In this line

中增加实例化的超时时间

let results = await channel.sendInstantiateProposal(request, 120000);

Answer 3

确保您拥有hyperledger/fabric-ccenv:<version>张图片。必须在链码实例化期间形成链码容器。

Answer 4

我也遇到了同样的问题，请按照以下步骤进行修复

首先删除所有docker容器和图像。
重新启动docker
再次下载所有图像并增加app文件夹中的超时时间

let results = await channel.sendInstantiateProposal（request，120000）;
如果错误仍然存在，请尝试使用sudo运行./runApp.sh和./testAPI.sh。
