## Поверніть токен { #return-the-token }

Відповідь точки входу `token` має бути об'єктом JSON.

Вона повинна містити `token_type`. У нашому випадку, оскільки ми використовуємо токени «Bearer», тип токена має бути «`bearer`».

# 使用密碼（與雜湊）的 OAuth2、以 Bearer 搭配 JWT 權杖 { #oauth2-with-password-and-hashing-bearer-with-jwt-tokens }

現在我們已經有完整的安全流程了，接下來用 <abbr title="JSON Web Tokens - JSON 網路權杖">JWT</abbr> 權杖與安全的密碼雜湊，讓應用真正安全。

這份程式碼可以直接用在你的應用中，把密碼雜湊存進資料庫等等。

我們會從上一章的內容繼續往下擴充。

## 關於 JWT { #about-jwt }

JWT 的意思是「JSON Web Tokens」。

它是一種把 JSON 物件編碼成一段長且緊密（沒有空白）的字串的標準。看起來像這樣：

```

	if err != nil {
		return err
	}

	// Verify if the authToken already contains
	// <Key> <Token> like format, if this is
	// already present we can blindly use the
	// authToken as is instead of adding 'Bearer'
	tokens := strings.Fields(target.args.AuthToken)
	switch len(tokens) {
	case 2:
		req.Header.Set("Authorization", target.args.AuthToken)
	case 1:

    print('body: ' + id_token_response.text)

    # we can now use the id_token as much as we want to access protected resources.
    tokens = json.loads(id_token_response.text)
    id_token = tokens['id_token']

    response = sts_client.assume_role_with_web_identity(
        RoleArn='arn:aws:iam::123456789012:user/svc-internal-api',
        RoleSessionName='test',
