不能调用与Hyperledger面料网络中节点应用交易？

问题描述 投票：0回答：1

问题：

我通过自己建立一个Hyperledger的光纤网络。然后我安装和实例.......我的网络是能够成功地在CLI容器上做交易。然后我试图做使用节点JS SDK的交易。在那里，我创建一个connection.js文件。使用它，我才得以发出管理员和用户身份。但是，当我尝试调用它让我错误的错误交易：PEM编码是必需的证书。

这是我connection.js文件看起来像。

这是我invoke.js文件看起来像。

const { FileSystemWallet, Gateway } = require("fabric-network");
const fs = require("fs");
const path = require("path");

const ccpPath = path.resolve(__dirname, ".", "connection.json");
const ccpJSON = fs.readFileSync(ccpPath, "utf8");
const ccp = JSON.parse(ccpJSON);

async function main() {
try {
// Create a new file system based wallet for managing identities.
const walletPath = path.join(process.cwd(), "wallet");
const wallet = new FileSystemWallet(walletPath);
console.log(`Wallet path: ${walletPath}`);

// Check to see if we've already enrolled the user.
const userExists = await wallet.exists("TharinduSA");
if (!userExists) {
console.log(
'An identity for the user "user1" does not exist in the wallet'
);
console.log("Run the registerUser.js application before retrying");
return;
}

// Create a new gateway for connecting to our peer node.
const gateway = new Gateway();
await gateway.connect(ccp, {
wallet,
identity: "TharinduSA",
discovery: { enabled: false }
});

console.log(gateway);

// Get the network (channel) our contract is deployed to.
const network = await gateway.getNetwork("mychannel");
// console.log(network);

// Get the contract from the network.
const contract = network.getContract("fabcar");
// console.log(contract);
``
// Submit the specified transaction.
// createCar transaction - requires 5 argument, ex: ('createCar', 'CAR12', 'Honda', 'Accord', 'Black', 'Tom')
// changeCarOwner transaction - requires 2 args , ex: ('changeCarOwner', 'CAR10', 'Dave')
await contract.submitTransaction(
"createCar",
"CAR12",
"Honda",
"Accord",
"Black",
"Tom"
);
console.log("Transaction has been submitted");

// Disconnect from the gateway.
await gateway.disconnect();
} catch (error) {
console.error(`Failed to submit transaction: ${error}`);
process.exit(1);
}
}

main();

我按行注释掉线，并检查其中的错误发生。然后，我能找出它是在这条线失败。 const network = await gateway.getNetwork("mychannel")当我寻找订货人的日志，它给我留下的终端上。

在对日志等。

有人可以帮我找出我做错了？这让我出去三至五天的发展，我是真的真的需要这个problem.Thank你解决！

既然你已经启用TLS，你需要传递一个PEM编码的证书，同时试图连接到订购者和同行。您可以通过查看here得到一个想法
