如何使用basic-ftp模块连接到节点中的FTPS服务器

Question

我正在使用https://www.npmjs.com/package/basic-ftp基本的ftp包连接到ftps服务器。我尝试了我的其他扩展，但无法连接到 ftps 服务器 下面是我的代码

const ftp = require("basic-ftp")

example();

async function example() {
    const client = new ftp.Client()
    client.ftp.verbose = true
    try {
        await client.access({
            host: "ftp.xxxx.xxxxx",
            user: "xxxx@xxxx.xx",
            password: "xxxxxxx",
            secure :true
        })
        await client.ensureDir("/my/remote/directory")
        console.log(await client.list())
        await client.uploadFrom("temp/readme.txt", "readme.txt")
       // await client.downloadTo("README_COPY.md", "README_FTP.md")
    }
    catch(err) {
        console.log(err)
    }
    client.close()
}

但给我一个错误

Login security: No encryption
> USER xx@xxx.xx
< 331 User name okay, need password for xxxx@xxx.xx.

您需要连接Explicit FTPS over TLS。 要通过 tls 连接到 ftps，您需要传递以下选项：

const fs = require('fs');

async function example() {
    const client = new ftp.Client()
    client.ftp.verbose = true
    try {
    const secureOptions = {
  // Necessary only if the server requires client certificate authentication.
  key: fs.readFileSync('client-key.pem'),
  cert: fs.readFileSync('client-cert.pem'),

  // Necessary only if the server uses a self-signed certificate.
  ca: [ fs.readFileSync('server-cert.pem') ],

  // Necessary only if the server's cert isn't for "localhost".
  checkServerIdentity: () => { return null; },
};
        await client.access({
            host: "ftp.xxxx.xxxxx",
            user: "xxxx@xxxx.xx",
            password: "xxxxxxx",
            secure :true,
secureOptions : secureOptions
        })
        await client.ensureDir("/my/remote/directory")
        console.log(await client.list())
        await client.uploadFrom("temp/readme.txt", "readme.txt")
       // await client.downloadTo("README_COPY.md", "README_FTP.md")
    }
    catch(err) {
        console.log(err)
    }
    client.close()
}
