当我指出 ChatGPT 的错误，它竟然改过来了 ChatGPT 的回答一般挺不错的，比搜索引擎好很多。经常问它一些问题，大部分时候有满意的答案。当然不是 100% 满意，有时答案是错的，甚至明显是错的，然后我就会忽略错误答案，或者它的回答不完全对，但我也能补充出正确答案，然后就结束对话了。但今天我尝试指出它的错误，它竟然修复了。起因：我想写一段 JavaScript 使用 sftp 传文件夹的代码，首先安装依赖npm install ssh2-sftp-clientChatGPT 给的答案是：const Client = require('ssh2-sftp-client'); const path = require('path'); const fs = require('fs'); const sftp = new Client(); const config = { host: 'your.server.com', port: 22, username: 'your-username', password: 'your-password', // Alternatively, use SSH keys // privateKey: require('fs').readFileSync('/path/to/your/private-key') }; const localDir = '/path/to/local/folder'; // Local directory to upload const remoteDir = '/path/to/remote/folder'; // Remote destination directory // Function to recursively upload files and directories async function uploadDir(localPath, remotePath) { try { // Connect to the SFTP server await sftp.connect(config); // Ensure the remote directory exists await sftp.mkdir(remotePath, true); // 'true' means recursive mkdir // Read the contents of the local directory const files = await fs.promises.readdir(localPath); // Iterate through each file/subdirectory in the local directory for (let file of files) { const localFile = path.join(localPath, file); const remoteFile = path.join(remotePath, file); // Check if it's a file or directory const stats = await fs.promises.stat(localFile); if (stats.isDirectory()) { // If it's a directory, recursively upload it await uploadDir(localFile, remoteFile); } else { // If it's a file, upload it await sftp.put(localFile, remoteFile); console.log(`Uploaded file: ${localFile} -> ${remoteFile}`); } } console.log('Directory upload complete!'); } catch (err) { console.error('Error uploading directory:', err); } finally { // Close the SFTP connection sftp.end(); } } // Start uploading the directory uploadDir(localDir, remoteDir);这里有个问题，文件夹可能会有子文件夹，会递归调用 uploadDir 方法，在递归调用时会重复连接 sftp ，会报错：Error: connect: An existing SFTP connection is already defined at SftpClient.fmtError (/Users/wjf/wjf/repo/js-scp/node_modules/ssh2-sftp-client/src/index.js:94:22) at SftpClient.connect (/Users/wjf/wjf/repo/js-scp/node_modules/ssh2-sftp-client/src/index.js:188:20) at uploadDir (/Users/wjf/wjf/repo/js-scp/test2.js:32:20) at uploadDir (/Users/wjf/wjf/repo/js-scp/test2.js:50:23) { code: 'ERR_NOT_CONNECTED', custom: true }于是向 ChatGPT 指出错误：This code do not work. Because in the recursion, you connect sftp multiple times于是 ChatGPT 重新写了代码，把连接 sftp 放在递归函数的外面，给出了可运行的代码。const Client = require('ssh2-sftp-client'); const path = require('path'); const fs = require('fs'); const sftp = new Client(); const config = { host: 'your.server.com', port: 22, username: 'your-username', password: 'your-password', // Alternatively, use SSH keys // privateKey: require('fs').readFileSync('/path/to/your/private-key') }; const localDir = '/path/to/local/folder'; // Local directory to upload const remoteDir = '/path/to/remote/folder'; // Remote destination directory // Function to recursively upload files and directories async function uploadDir(localPath, remotePath) { try { // Read the contents of the local directory const files = await fs.promises.readdir(localPath); // Iterate through each file/subdirectory in the local directory for (let file of files) { const localFile = path.join(localPath, file); const remoteFile = path.join(remotePath, file); // Check if it's a file or directory const stats = await fs.promises.stat(localFile); if (stats.isDirectory()) { // If it's a directory, create it on the remote server await sftp.mkdir(remoteFile, true); // 'true' means recursive mkdir console.log(`Created directory: ${remoteFile}`); // Recursively upload the directory's contents await uploadDir(localFile, remoteFile); } else { // If it's a file, upload it await sftp.put(localFile, remoteFile); console.log(`Uploaded file: ${localFile} -> ${remoteFile}`); } } console.log('Directory upload complete!'); } catch (err) { console.error('Error uploading directory:', err); } } // Start the upload process async function startUpload() { try { // Connect to the SFTP server once await sftp.connect(config); // Upload the entire directory await uploadDir(localDir, remoteDir); } catch (err) { console.error('Error during connection or upload:', err); } finally { // Always end the SFTP connection when done sftp.end(); } } // Start the process startUpload();没想到人工智能还可以这样操作！
