Example Usage

package main

import (
	"context"
	"fmt"
	"log"
	"os"

	"github.com/manicminer/hamilton/auth"
	"github.com/manicminer/hamilton/environments"
	"github.com/manicminer/hamilton/msgraph"
	"github.com/manicminer/hamilton/odata"
)

var (
	tenantId     = os.Getenv("TENANT_ID")
	clientId     = os.Getenv("CLIENT_ID")
	clientSecret = os.Getenv("CLIENT_SECRET")
)

func main() {
	ctx := context.Background()

	authConfig := &auth.Config{
		Environment:            environments.Global,
		TenantID:               tenantId,
		ClientID:               clientId,
		ClientSecret:           clientSecret,
		EnableClientSecretAuth: true,
	}

	authorizer, err := authConfig.NewAuthorizer(ctx, auth.MsGraph)
	if err != nil {
		log.Fatal(err)
	}

	client := msgraph.NewUsersClient(tenantId)
	client.BaseClient.Authorizer = authorizer

	users, _, err := client.List(ctx, odata.Query{})
	if err != nil {
		log.Println(err)
		return
	}
	if users == nil {
		log.Println("bad API response, nil result received")
		return
	}
	for _, user := range *users {
		fmt.Printf("%s: %s <%s>\n", *user.ID, *user.DisplayName, *user.UserPrincipalName)
	}
}

Contributing

Contributions are welcomed! Please note that clients must have tests that cover all methods where feasible.

Please raise a pull request on GitHub to submit contributions. Bug reports and feature requests are happily received.

Testing

Testing requires an Azure AD tenant and real credentials. Note that some tests require an Azure AD Premium P2 license and/or an Office 365 license. You can authenticate with any supported method for the client tests, and the auth tests are split by authentication method.

Note that each client generally has a single test that exercises all methods. This is to help ensure that test objects are cleaned up where possible. Where tests fail, often objects will be left behind and should be cleaned up separately. The test-cleanup command can be used to delete leftover test objects.

It's recommended to use an isolated tenant for testing and not a production tenant.

To run all the tests:

$ make test
