Retrieve content using cid from ipfs cluster

Help

I installed the ipfs cluster by following this link
IPFS Cluster | IPFS Docs and now I am trying to retrieve a file added on the cluster nodes via CID using this script

 retrieve(CID) url = "http://localhost:8080/ipfs/" + CID try: response = requests.get(url, allow_redirects=True) if response.status_code == 200: with open("file_downloaded.txt", "wb") as file: file.write(response.content) print("File downloaded successfully!") else: print(f"Error {response.status_code} when downloading the filee.") except Exception as e: print(f"An error occurred during the request: {e}") CID = "Qmeff6BfzCcd7ekaUMTeQbMqMPvMpwrP8LPRjkwAr4XVyD" retrieve(CID)

however the result I get is this

An error occurred during the requesta: HTTPConnectionPool(host='bafybeihstf2oihh4imkkkahxbswylzqr3xi2mrwkqlrv3h7rvsox2sgwnq.ipfs.localhost', port=8080): Max retries exceeded with url: / (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object at 0x7f6a1f202bc0>: Failed to resolve 'bafybeihstf2oihh4imkkkahxbswylzqr3xi2mrwkqlrv3h7rvsox2sgwnq.ipfs.localhost' ([Errno -2] Name or service not known)"))

and I don’t know how to solve it

Your original request is converted and redirected to the “subdomain gateway” form, instead of the “path gateway”. Any chance you have enabled that? kubo/docs/config.md at master · ipfs/kubo · GitHub

Browsers know how to deal with *.ipfs.localhost I think, but I’m not sure how to make the machine deal with that directly. You can google something like “resolving localhost subdomain” and go from there, or just disable the subdomain gateway.

Also, if you have not enabled subdomain gateway at all, you may try requesting to 127.0.0.1:8080 instead of localhost:8080.

I don’t have that flag in my configuration. My configuration for my ipfs node that try to retrieve the content using CID is

while the docker-compose.yml for the cluster is version: ‘3.4’

# This is an example docker-compose file to quickly test an IPFS Cluster # with multiple peers on a contained environment. # It runs 3 cluster peers (cluster0, cluster1...) attached to kubo daemons # (ipfs0, ipfs1...) using the CRDT consensus component. Cluster peers # autodiscover themselves using mDNS on the docker internal network. # # To interact with the cluster use "ipfs-cluster-ctl" (the cluster0 API port is # exposed to the locahost. You can also "docker exec -ti cluster0 sh" and run # it from the container. "ipfs-cluster-ctl peers ls" should show all 3 peers a few # seconds after start. # # For persistence, a "compose" folder is created and used to store configurations # and states. This can be used to edit configurations in subsequent runs.
