Question

我得到了

Error: Common connection profile is missing this client's organization and certificate authority

在运行gateway.getClient().getCertificateAuthority()代码行时出错。我的连接配置文件在那里，据我了解，没有问题。

以下是我的nodejs客户端代码。

'use strict';

const { FileSystemWallet, Gateway, X509WalletMixin } = require('fabric-network');
const path = require('path');

const ccpPath = "../connection-ogr4.json";

async function main() {
    try {

        let user = 'user2';
        // 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}`);

        const userExists = await wallet.exists(user);

        // Check to see if we've already enrolled the admin user.
        const adminExists = await wallet.exists('admin');

        // Create a new gateway for connecting to our peer node.
        const gateway = new Gateway();
        await gateway.connect(ccpPath, { wallet, identity: 'admin', discovery: { enabled: true, asLocalhost: true } });
        // Get the CA client object from the gateway for interacting with the CA.
        const ca = gateway.getClient().getCertificateAuthority()

它使用以下连接json文件。

{

"version": "1.0.0",
"client": {
    "organization": "Org4",
    "connection": {
        "timeout": {
            "peer": {
                "endorser": "300"
            }
        }
    }
},
"organizations": {
    .......

"certificateAuthorities": {
    "ca.org4.bc4scm.de": {

        },
        "httpOptions": {
            "verify": false

    }
}

}
