如何从 IPFS 找回丢失的文件？

Question

几周前，我尝试启动本地 IPFS 节点，发布文件，并且能够通过发布网关访问它。我以为文件会被很多节点存储，所以我从本地机器上删除了它，现在我不能再通过 ID (QmNvxsaXqWoLR1NNJpiRXTEo57ptyg3CjSGBrgeyiyFiPm) 访问文件了。

我注意到我仍然可以从 webui 访问数据，但只能看到原始数据而不是文件。有没有办法找回文件？

Answer 1

我实际上可以通过一个简单的 ipfs cat QmNvxsaXqWoLR1NNJpiRXTEo57ptyg3CjSGBrgeyiyFiPm 来检索这个 CID：

我认为这个文件会被很多节点存储，所以我从我的本地机器上删除了它

重要的是要注意，数据仅由其他节点临时存储，如果它们自己访问内容。如果您希望数据长期可靠地存在，您可以使用 Pinata 之类的固定服务，因为您需要向他们付费以保持数据固定。

否则，您必须依靠其他节点来固定您的数据以确保数据仍然可用。
