<!-- Answer -->
To resolve the HTTP 401 Unauthorized error when running the CypherAPI on the
Swagger page after deploying HugeGraph and HugeGraph-Hubble via Docker, you
need to ensure that the correct authorization headers are being sent with your
requests. The `CypherAPI` class expects either a Basic or Bearer token for
authorization.
### Steps to Resolve
1. **Basic Authentication**:
- Encode your username and password in Base64 format.
- Add the `Authorization` header with the value `Basic
<encoded-credentials>`.
2. **Bearer Token Authentication**:
- Obtain a valid token.
- Add the `Authorization` header with the value `Bearer <token>`.
### Example for Basic Authentication
If your username is `user` and your password is `password`, you need to
encode `user:password` in Base64. The encoded string for `user:password` is
`dXNlcjpwYXNzd29yZA==`.
Add the following header to your request:
```
Authorization: Basic dXNlcjpwYXNzd29yZA==
```
### Example for Bearer Token Authentication
If you have a token `your_token`, add the following header to your request:
```
Authorization: Bearer your_token
```
### Code Snippet for Adding Headers in Swagger
If you are using Swagger UI, you can add the authorization header as follows:
```javascript
// Add this script to your Swagger UI initialization code
swaggerUi.api.clientAuthorizations.add(
'basicAuth',
new SwaggerClient.ApiKeyAuthorization('Authorization', 'Basic
dXNlcjpwYXNzd29yZA==', 'header')
);
// For Bearer token
swaggerUi.api.clientAuthorizations.add(
'bearerAuth',
new SwaggerClient.ApiKeyAuthorization('Authorization', 'Bearer
your_token', 'header')
);
```
Ensure that you replace `dXNlcjpwYXNzd29yZA==` and `your_token` with your
actual encoded credentials and token, respectively.
Additionally, verify that the authentication settings in your
`gremlin-server.yaml` and `rest-server.properties` files are correctly
configured. The `gremlin-server.yaml` file should have the following
authentication settings:
```yaml
authentication: {
authenticator: org.apache.hugegraph.auth.StandardAuthenticator,
authenticationHandler: org.apache.hugegraph.auth.WsAndHttpBasicAuthHandler,
config: {tokens: conf/rest-server.properties}
}
```
Ensure that the `rest-server.properties` file contains the correct token
configurations as referenced in the `gremlin-server.yaml` file. This setup
ensures that the server is properly configured to handle authentication
requests.
The `HugeGraphAuthProxy` class in HugeGraph handles various authentication
and authorization tasks, ensuring that the correct permissions are verified for
different operations
