背景: 我已经修改了第一个网络文件(到一个有 2 个组织和每个对等点的网络)并在上面安装了我自己的链代码。此外,我制作了一个 connection.yaml 文件来与网络交互。
问题: 但是当我尝试从nodeSDK获取网络通道并建立网关时,我遇到了这个错误:
错误:[网络]:_initializeInternalChannel:无法初始化通道。尝试联系 2 位同行。最后一个错误是 Error: 2 UNKNOWN: Stream removed
无法评估事务:错误:无法初始化通道。尝试联系 2 位同行。最后一个错误是 Error: 2 UNKNOWN: Stream removed
您可以在下面找到我客户端的代码。执行时可能会出现错误gateway.getNetwork('mychannel')
。
let connectionProfile = yaml.safeLoad(fs.readFileSync('./connection.yaml', 'utf8'));
// Create a new gateway for connecting to our peer node.
const gateway = new Gateway();
await gateway.connect(connectionProfile, { wallet, identity: 'user1', discovery: { enabled: false } });
// Get the network (channel) our contract is deployed to.
const network = await gateway.getNetwork('mychannel');
// Get the contract from the network.
const contract = network.getContract('bankpeerContract');
var result = await contract.evaluateTransaction('queryAllStamps');
这是我的 connection.yaml 文件:

我一直无法弄清楚是connection.yaml
文件有问题还是网络有问题。
