我在研究中能找到的唯一答案是从 PC 上的目录上传多个文件。这不是我想要做的。我正在尝试在 ipfs 中创建一个目录，然后使用 js-ipfs 仅使用纯 JavaScript 将新文件添加到该目录，通常一次一个文件。

我从概念上理解 ipfs 中的目录只是另一个文件。但我不明白如何创建该目录（文件）并将其他文件添加到其中以供以后检索，特别是使用 js-ipfs 和纯 javascript 代码。

我隐含地不使用 node.js，因此也没有反应、角度或 vue。

这适用于 ipfs 上没有目录的单个文件：

<!DOCTYPE html>
<html>
<head>
  <script src="https://cdn.jsdelivr.net/npm/ipfs/dist/index.min.js"></script>
</head>
<script>
    document.addEventListener('DOMContentLoaded', async () => {
        const nodeId = 'ipfs-' + Math.random()
        const node = await Ipfs.create({ repo: nodeId })
        console.log("Your node: " + nodeId)
        window.node = node
        const status = node.isOnline() ? 'online' : 'offline'
        console.log(`Node status: ${status}`)
        async function addFile () {
            for await (const { cid } of node.add('Some file content!')) {
                console.log('successfully stored', cid)
                cidhash=cid.toBaseEncodedString()
                console.log(cidhash)
            }
        }
        addFile()
    })
</script>
<body>
</body>
</html>

如何使这项工作能够创建一个目录并最初向其中添加一个文件，然后稍后将另一个文件添加到创建的目录中（伪代码）？

  async function addFile () {
    for await (const { directory, filename } of node.add('/someDirectory/someFilename','Some file content!')) {
      console.log('successfully stored', directory, filename)             
      console.log(directory, filename)
    }
  }

翻阅了 js-ipfs文档，终于找到了答案。

只创建一个目录：

await ipfs.files.mkdir('/my/beautiful/directory')

创建目录路径并同时向其中添加文件的完整工作示例：

<!DOCTYPE html>
<html>
<head>
  <script src="https://cdn.jsdelivr.net/npm/ipfs/dist/index.min.js"></script>
</head>
<script>
    document.addEventListener('DOMContentLoaded', async () => {
        const nodeId = 'ipfs-' + Math.random()
        const node = await Ipfs.create({ repo: nodeId })
        console.log("Your node: " + nodeId)
        window.node = node
        const status = node.isOnline() ? 'online' : 'offline'
        console.log(`Node status: ${status}`)

        //create a variable with the directory path '/my/beautiful/directory' 
        // and a file 'awesomesause.txt' with the content 'ABC' 
        var files = [{
            path: '/my/beautiful/directory/firstfile.txt',
            content: 'ABC'
        }]

        addFile(files) //add the first file       

        //update the 'files' variable to add another file to the directory path '/mybeautiful/directory' in ipfs
        files = [{
            path: '/my/beautiful/directory/secondfile.txt',
            content: 'DEF'
        }]
        
        addFile(files) //add the sectond file

        //function to add the files
        async function addFile (files) {
            for await (const result of node.add(files)) {
                console.log(result)
            }
        }
    })
</script>
<body>
</body>
</html>

结果：
