I gusss my infura is wrong with the setup.

issue: Failed to load resource: the server responded with a status of 401 (Unauthorized)

I tried to setup projectID and the secret key from infura, but it did not work.

expect:

1. it seems they are already on v3 - I should move this
2. the error (and the docs) suggests that I am using GET - change to POST

reference: https://www.youtube.com/watch?v=GKJBEEXUha0

However, I lost how I setup that. Could anybody suggest any idea?

Answer 1

You're missing the project id that infura.io requires the first screenshot returns that.

Following the sample request provided by infura.io, an Authorization header is required when a request sent, you might need to re-implement your ipfsHttpClient with the following code.

Also, there's a bug reported in older ipfs-http-client that can't pass the Authorization header properly but has been fixed in v44.0.1, make sure you're using the latest version of this package as well.

For the second screenshot, /api/v0/add is a POST method that is defined by infura.io, paste the URL into your browser result to trigger a GET method

const client = ipfsHttpClient({
    host: 'https://ipfs.infura.io:5001/api/v0',
    headers: {
                Authorization:
                    'Your infura token here'
            }
})
