ipfs.add和ipfs.dag.put有什么区别？
使用js-ipfs lib，我正在努力寻找有关以下命令之间区别的良好信息：
> await ipfs.add('hello world',{cidVersion:1})
{
path: 'bafkreifzjut3te2nhyekklss27nh3k72ysco7y32koao5eei66wof36n5e',
cid: CID(bafkreifzjut3te2nhyekklss27nh3k72ysco7y32koao5eei66wof36n5e),
size: 11,
mode: undefined,
mtime: undefined
}
> await ipfs.dag.put('hello world')
CID(bafyreifg3qptriirganaf6ggmbdhclgzz7gncundvtsyrovyzqigm25jfe)
我的期望：CID会相同。
会欣赏任何指示。

My expectation: CIDs would be the same.
Would appreciate any pointers.

以下基于 Kubo RPC，但 JS-IPFS 基于它，并且很可能做了类似的事情（唯一的区别可能是 Kubo 中的
dag put默认情况下需要/需要 dag-json）ipfs dag put允许您操作除文件和目录之外的 IPLD 数据结构。在 Kubo 中，此命令将假定输入为 dag-json 并将存储它作为二进制 dag-cbor。您可以在 https://cid.ipfs.tech 上比较生成的 CID – 在您的示例中：
ipfs add创建了原始块（因为“hello world”适合单个块，不需要 dag-pb）ipfs dag创建了 dag-cbor（因为这是默认值--存储编解码器）Below is based on
ipfs addanddag putfrom Kubo RPC, but JS-IPFS was based on it and most likely does something similar (only difference may be thatdag putin Kubo expects/requires dag-json by default)ipfs addis for adding files and directories and representing them as UnixFS. It will chunk bigger files into smaller blocks and represent them as dag-pb or raw bytes (leaves).ipfs dag putallows you to operate on IPLD data structures other than files and directories. In Kubo, this command will assume input to be dag-json and will store it as binary dag-cbor.You can compare produced CIDs at https://cid.ipfs.tech – in your example:
ipfs addcreated raw block (because 'hello world' fits in a single block, no need for dag-pb)ipfs dagcreated dag-cbor (because that is the default--store-codec)
