Question

我使用devmode（https://github.com/hyperledger/fabric-samples/tree/release-1.1/chaincode-docker-devmode）设置了Hyperledger Fabric网络，并启动了链码。我需要一种与网络通信的方式（创建/加入频道，调用链码）。

我尝试使用python-SDK（https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md）。初始化客户端实例需要network.json配置文件，但fabric-samples中未提供该文件，因此我尝试创建自己的文件。它没有用。

代码：

from hfc.fabric import Client

cli = Client(net_profile="network.json")

print(cli.organizations)  # orgs in the network
org1_admin = cli.get_user('org1.example.com', 'Admin')
response = cli.channel_create(
    'orderer',
    'myc',
    org1_admin,
    'myc.tx')

订货人输出：

http2Server.HandleStreams收到来自客户的虚假问候

我试图为orederer使用不同的证书和名称，但它没有帮助。

network.json：
