如何通过编程方式创建Hyperledger钱包？自定义路径需求

Absolutely! You don’t have to stick with the default wallet path—you can create a wallet pointing to any directory you choose using the FileSystemWallet class directly. Here’s how to do it, step by step:

Step 1: Import the required class #

First, make sure you pull in the FileSystemWallet class from the Composer library:

const { FileSystemWallet } = require('composer-common');

Step 2: Initialize your custom path wallet #

Instantiate the FileSystemWallet by passing your desired directory path as the argument. This can be any valid filesystem path your application has read/write access to—no need to follow the default ~/.composer/client-data/ structure:

// Replace this with your actual custom directory path
const customWalletDir = '/home/your-username/my-custom-wallet';
const wallet = new FileSystemWallet(customWalletDir);

Step 3: Link it to your BizNetworkConnection (if needed) #

If you want to use this custom wallet with an existing bizNetworkConnection instance, you can explicitly set it using the setWallet method:

this.bizNetworkConnection.setWallet(wallet);

// Now when you fetch the wallet, it will use your custom path
const adminWallet = await this.bizNetworkConnection.cardStore.getWallet('admin@proak-hyperledger-network');

Bonus: Import cards to your custom wallet #

If you need to add existing identity cards to this new wallet, use the import method:

// Assuming you have a card object (e.g., loaded from a .card file)
await wallet.import('admin@proak-hyperledger-network', card);

This gives you full control over where your wallet data is stored, avoiding the default path you can’t use.
