# msauth
## Introduction
Very simple package to authorize applications against [Microsoft identity platform].
It utilizes [v2.0 endpoint] so that it can authorize users using both personal (Microsoft) and organizational (Azure AD) account.
## Usage
### Device authorization grant
- [OAuth 2.0 device authorization grant flow]
```go
const (
tenantID = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
clientID = "YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY"
tokenCachePath = "token_cache.json"
)
var scopes = []string{"openid", "profile", "offline_access", "User.Read", "Files.Read"}
ctx := context.Background()
m := msauth.NewManager()
m.LoadFile(tokenCachePath)
ts, err := m.DeviceAuthorizationGrant(ctx, tenantID, clientID, scopes, nil)
if err != nil {
log.Fatal(err)
}
m.SaveFile(tokenCachePath)
httpClient := oauth2.NewClient(ctx, ts)
...
```
### Client credentials grant
- [OAuth 2.0 client credentials grant flow]
```go
const (
tenantID = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
clientID = "YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY"
clientSecret = "ZZZZZZZZZZZZZZZZZZZZZZZZ"
)
var scopes = []string{msauth.DefaultMSGraphScope}
ctx := context.Background()
m := msauth.NewManager()
ts, err := m.ClientCredentialsGrant(ctx, tenantID, clientID, clientSecret, scopes)
if err != nil {
log.Fatal(err)
}
httpClient := oauth2.NewClient(ctx, ts)
...
```
### Resource owner password credentials grant
- [OAuth 2.0 resource owner passowrd credentials grant flow]
```go
const (
tenantID = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
clientID = "YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY"
clientSecret = "ZZZZZZZZZZZZZZZZZZZZZZZZ"
username = "user.name@your-domain.com"
password = "secure-password"
)
var scopes = []string{msauth.DefaultMSGraphScope}
ctx := context.Background()
m := msauth.NewManager()
ts, err := m.ResourceOwnerPasswordGrant(ctx, tenantID, clientID, clientSecret, username, password, scopes)
if err != nil {
log.Fatal(err)
}
httpClient := oauth2.NewClient(ctx, ts)
...
```
