Get Object Data via go-ipfs-http-client library

Help
1

I am able to get traits of project using cURL as below

curl -X POST -u “projectId:projectSecreat” “https://ipfs.infura.io:5001/api/v0/get?arg=QmNuChxuijmcDZ1JQE1NMPhZAtmu1QQgqUpN8TxVtXw4aH/1”

How to get same data via golang library

package main

import (

    "context"

    "encoding/base64"

    "fmt"

    "net/http"

    "os"

    ipfsApi "github.com/ipfs/go-ipfs-http-client" // v0.1.0

    path "github.com/ipfs/interface-go-ipfs-core/path"

)

func main() {

    projectId := "1ylb...."

    projectSecret := "1f9...."

    httpClient := &http.Client{}

    httpApi, err := ipfsApi.NewURLApiWithClient("https://ipfs.infura.io:5001", httpClient)

    if err != nil {

        fmt.Println(err)

        os.Exit(1)

    }

    httpApi.Headers.Add("Authorization", "Basic "+basicAuth(projectId, projectSecret))

    //content := strings.NewReader("Infura IPFS - Getting started demo.")

    mypath := path.New("Qmb5zeyvU7ZpotLDzkUmSeMDA71MExp8eJyNeefGdoeA2x")

    files, err := httpApi.Object().Get(context.Background(), mypath)

    if err != nil {

        fmt.Println(err)

        os.Exit(1)

    }

    for i := 0; i < len(files.Links()); i++ {

        fmt.Println(files.Links()[i].Cid)

    }

    fmt.Println(len(files.Links()))

}

func basicAuth(projectId, projectSecret string) string {

    auth := projectId + ":" + projectSecret

    return base64.StdEncoding.EncodeToString([]byte(auth))

}

This give me right number of links, how to get data which we receive via cURL from links object ?

A Node implements the Block interface so you can use RawData() to get the content:

https://pkg.go.dev/github.com/ipfs/go-block-format#Block

However, if you are trying to download normal “unixfs” files from the API, you should use the UnixFS() functions not the Object ones.

https://pkg.go.dev/github.com/ipfs/go-ipfs-http-client#UnixfsAPI.Get

You will need to cast the resulting files.Node into a files.File or files.Directory as needed, and then you can read stuff.
