Heads up:
ipfs://
addresses in this project will break when it attempts to read a CIDv1ipfs://
addressesThis code assumes every CID is CIDv0 (looks the same as Multihash, so it is parsed as Multihash here):
public InputStream getInputStream() throws IOException {
Multihash filePointer = Multihash.fromBase58(location.toString().replaceFirst("ipfs://", ""));
byte[] fileContents = new byte[0];
try {
fileContents = ipfs.cat(filePointer);
} catch (IOException e) {
logger.error("Failed to retrieve object", e);
return null;
}
Try parsing ipfs://bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi
โ it is not Base58 (it is CIDv1 in Base32), so will throw an exception.
Always assume localtion
is a CID and parse it using a library that understands CIDv1.
You can use CID implementation from java-cid, you can also peek at how CIDs are used in Peergos
