如何在Hyperledger Fabric中找到链码位置？

Question

我正在跟踪GitHub上的结构样本-余额转移项目

我能够逐步设置链代码，并在节点中使用其提供的示例链代码查询交易。

我想在github.com/目录中包含我自己的自定义链代码，我能够通过提供curl命令来安装链代码

curl -s -X POST \
>   http://localhost:4000/chaincodes \
>   -H "authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NTkxNTU3NzIsInVzZXJuYW1lIjoiSmltIiwib3JnTmFtZSI6Im9yZzEiLCJpYXQiOjE1NTkxMTk3NzJ9.52cwFysSFcADjvGUtri-hBSERhj2lz3MiGNk8yvBT-Q" \
>   -H "content-type: application/json" \
>   -d '{
> "peers": ["peer1","peer2"],
> "chaincodeName":"mycc",
> "chaincodePath":"github.com/car-trade",
> "chaincodeVersion":"v0"
> }'

我能够收到消息 在组织org1上成功安装了链码

但是当我使用curl命令实例化链代码时

curl -s -X POST \
>   http://localhost:4000/channels/mychannel/chaincodes \
>   -H "authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NTkxNTU3NzIsInVzZXJuYW1lIjoiSmltIiwib3JnTmFtZSI6Im9yZzEiLCJpYXQiOjE1NTkxMTk3NzJ9.52cwFysSFcADjvGUtri-hBSERhj2lz3MiGNk8yvBT-Q" \
>   -H "content-type: application/json" \
>   -d '{
> "chaincodeName":"mycc",
> "chaincodeVersion":"v0",
> "args":["a","100","b","200"]
> }'

我收到一条错误消息 无法发送实例化投标或接收有效响应。响应为空或状态不是200。正在退出...

当我尝试将我在链代码API中得到的响应记录在文件here中时。

 const results = await channel.sendInstantiateProposal(request);

        proposalResponses.forEach((pr: ProposalResponse) => {
            console.log(pr);
        }

我收到消息，

        'grpc.default_authority': 'peer1.org1.example.com' } },
  isProposalResponse: true }

我进入了对等容器，并查看github.com目录，该目录需要同时具有example_cc和我的自定义链代码的链代码。但是我都找不到。

我想知道示例代码和自定义代码都位于链代码所在的位置。
