配置文件 sftp.json

{
    "zhixingyun_production": {
        "sftp": {
            "host": "10.10.10.10",
            "port": 22,
            "username": "xxx",
            "password": "xxx"
        },
        "pathConfig": {
            "remotePath": "/home/xiaochong/web/website/dist",
            "remoteBackupPath": "/home/xiaochong/web/website/dist_backup",
            "localPath": "./dist"
        }
    },
    "zhixingyun_test": {
        "sftp": {
            "host": "10.10.10.10",
            "port": 22,
            "username": "xxx",
            "password": "xxx"
        },
        "pathConfig": {
            "remotePath": "/home/xiaochong/web/test",
            "remoteBackupPath": "/home/xiaochong/web/test_backup",
            "localPath": "./test"
        }
    }
}

上传文件 upload.js

let Client = require('ssh2-sftp-client');
let client = new Client();
const config = require('./sftp.json')
const args = process.argv.slice(2)
const { sftp, pathConfig } = config[args[0]];
 
const main = async () => {
    try {
        await client.connect(sftp);
        //删除备份文件,如果有
        if (await client.exists(pathConfig.remoteBackupPath)) {
            await client.rmdir(pathConfig.remoteBackupPath, true)
            console.log('删除备份文件成功')
        }
 
        // 重命名之前的文件作为备份文件
        if (await client.exists(pathConfig.remotePath)) {
            await client.rename(pathConfig.remotePath, pathConfig.remoteBackupPath)
            console.log('新的备份文件重命名成功');
        }
        // 上传本地文件
        await client.uploadDir(pathConfig.localPath, pathConfig.remotePath);
        console.log('上传成功')
    } catch (err) {
        console.log(err);
    } finally {
        client.end();
    }
}
 
main();

最后我们怎么执行upload呢，打包后用node执行即可：

`package.json`
```json
"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build &  node script/upload.js zhixingyun_production",
    "build:test": "vue-cli-service build --mode test &  node script/upload.js zhixingyun_test",
}

注意点：sftp里的localPath写的是./ 因为npm run build执行时，dist文件夹在当前命令行的同级目录。

这种上传方式是 SFTP，不是stp，用的账号密码是ssh的。
