Azure ACR login using golang sdk

I'm looking for a way to get Azure ACR access token using golang sdk. Similar to the result of the following console commands:

az login --service-principal -u <app-id> -p <password-or-cert> --tenant <tenant>
az acr login --name <registry id> --expose-token --only-show-errors

Here is my solution. Just set tenantId and acrService and run it. The output will give you user and password (token) to use in a docker login command. Please note: User is literally "00000000-0000-0000-0000-000000000000". Don't replace that.

package main

import (
    "context"
    "encoding/json"
    "fmt"
    "net/http"
    "net/url"

    "github.com/Azure/azure-sdk-for-go/sdk/azcore/policy"
    "github.com/Azure/azure-sdk-for-go/sdk/azidentity"
)

func main() {
    tenantId := "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    acrService := "crmichitest.azurecr.io"
    cred, err := azidentity.NewDefaultAzureCredential(nil)
    if err != nil {
        panic(err)
    }
    ctx := context.Background()
    aadToken, err := cred.GetToken(ctx, policy.TokenRequestOptions{Scopes: []string{"https://management.azure.com/.default"}})
    if err != nil {
        panic(err)
    }
    formData := url.Values{
        "grant_type":   {"access_token"},
        "service":      {acrService},
        "tenant":       {tenantId},
        "access_token": {aadToken.Token},
    }
    jsonResponse, err := http.PostForm(fmt.Sprintf("https://%s/oauth2/exchange", acrService), formData)
    if err != nil {
        panic(err)
    }
    var response map[string]interface{}
    json.NewDecoder(jsonResponse.Body).Decode(&response)
    fmt.Println("User: 00000000-0000-0000-0000-000000000000")
    fmt.Println("Token:", response["refresh_token"])
}

Then, just log into the registry:

docker login -u "00000000-0000-0000-0000-000000000000" -p "<TOKEN FROM OUTPUT>" crmichitest.azurecr.io
