node-red-contrib-oauth2
— це вузол Node-RED, який забезпечує потік автентифікації OAuth2. Цей вузол використовує протокол OAuth2 для отримання маркера доступу, який можна використовувати для виконання автентифікованих запитів API.

Ви можете встановити цей вузол безпосередньо з редактора Node-RED, перейшовши в меню «Керування палітрою» та ввівши пошуковий запит node-red-contrib-oauth2
. Крім того, ви можете встановити його за допомогою npm:
$ cd ~/.node-red
$ npm install node-red-contrib-oauth2
Вузол вимагає URL-адресу маркера доступу та набір облікових даних клієнта для автентифікації за допомогою цієї URL-адреси. Вузол згенерує HTTP-запит до URL-адреси маркера доступу, щоб отримати маркер доступу за допомогою облікових даних клієнта. Маркер доступу може зберігатися у властивості повідомлення, яке можуть використовувати наступні вузли в потоці.
Вузол забезпечує два режими роботи:

Input | Type | Description |
---|---|---|
container | string | This refers to the name of the container that is intended to receive the message object. By default, it is set to oauth2Response. |
grant type | object | This specifies the grant type used to obtain the access token. |
access token url | string | This is the URL used to obtain the access token. |
client id | string | This is the unique identifier for the client application. |
client secret | string | This is the secret key used to authenticate the client application. |
username | string | This is the username used for authentication. Grant Type: password |
password | string | This is the password used for authentication. Grant Type: password |
authorization endpoint | string | This is the URL of the authorization endpoint. Grant Type: authorization code |
code (read only) | string | This is the authorization code. Grant Type: authorization code |
scope | string | This specifies the scope of the access request. |
use proxy | boolean | This specifies whether to use a proxy or not. |
Proxy Configuration | object | This specifies the configuration for the proxy. User Proxy: true |
only send non-2xx responses to catch node | boolean | This specifies whether to only catch non-2xx responses. |
embedded credentials | boolean | This specifies whether to include the client credentials in the token request body for authentication purposes. |
reject Unauthorized | boolean | This specifies whether to reject unauthorized requests. The rejectUnauthorized parameter controls SSL/TLS certificate validation for the server, with true enforcing validation and false disabling it. |
Note:
- If running behind a proxy, the standard
http_proxy=...
environment variable should be set andNode-RED restarted, or use Proxy Configuration
. If Proxy Configuration was set, the configuration take precedence over environment variable.
- The OAuth redirect URL is set by default to
/oauth2/redirect
, which is the endpoint responsible for receiving the authorizationcode
.
Output | Description |
---|---|
access_token | This is the access token obtained from the OAuth2 server. |
expires_in | This is the duration of time, in seconds, until the access token expires. |
token_type | This is the type of the token. For example, “Bearer”. |
scope | This specifies the scope of the access granted by the token obtained. |
refresh_token | This is the refresh token that can be used to obtain a new access token before the current one expires. |
The msg.oauth2Request
object contains the OAuth2 request details that are set by the node. The following are the different types of credentials that can be used for authentication:
Client Credentials
The client credentials can be sent as part of the message payload to the node. The msg.oauth2Request.credentials
object should contain the following properties:
grant_type
(string): This specifies the grant type. For dynamic credentials, the value should be set to “client_credentials”.client_id
(string): This is the client ID of the OAuth2 client.client_secret
(string): This is the client secret of the OAuth2 client.scope
(string): This specifies the scope of the access requested.Here’s an example:
msg.oauth2Request = {
"access_token_url": "http://localhost:8080/v1/oauth/tokens",
"credentials": {
"grant_type": "client_credentials",
"client_id": "test_client_1",
"client_secret": "test_secret",
"scope": "read_write"
},
};
return msg;
Password
The username and password can be sent as part of the message payload to the node. The msg.oauth2Request.credentials
object should contain the following properties:
grant_type
(string): This specifies the grant type. For password credentials, the value should be set to “password”.client_id
(string): This is the client ID of the OAuth2 client.client_secret
(string): This is the client secret of the OAuth2 client.scope
(string): This specifies the scope of the access requested.username
(string): This is the username of the user.password
(string): This is the password of the user.Here’s an example:
msg.oauth2Request = {
"access_token_url": "http://localhost:8080/v1/oauth/tokens",
"credentials": {
"grant_type": "password",
"client_id": "test_client_1",
"client_secret": "test_secret",
"scope": "read_write",
"username": "test@user",
"password": "test_password"
},
};
return msg;
###
refreshToken
A refresh token can be used to obtain a new access token without requiring the user to re-authenticate. The msg.oauth2Request.credentials
object should contain the following properties:
grant_type
(string): This specifies the grant type. For refresh token credentials, the value should be set to “refresh_token”.client_id
(string): This is the client ID of the OAuth2 client.client_secret
(string): This is the client secret of the OAuth2 client.scope
(string): This specifies the scope of the access requested.refresh_token
(string): This is the refresh token obtained from a previous authentication.Here’s an example:
let refreshToken = global.get('refreshToken');
msg.oauth2Request = {
"access_token_url": "http://localhost:8080/v1/oauth/tokens",
"credentials": {
"grant_type": "refresh_token",
"client_id": "test_client_1",
"client_secret": "test_secret",
"scope": "read_write",
"refresh_token": refreshToken
},
};
return msg;
