<!-- Answer -->
The issue you're encountering, indicated by the
`java.lang.IllegalStateException` with the message "Missing authentication
context when verifying resource permission," suggests a problem with
authentication during your attempt to dynamically create a graph using the
HugeGraph API. It appears that the client might not be authenticated or the
authentication context is not properly established for the API call.
To address this, ensure your client is authenticated before making any API
requests, especially if your HugeGraph server requires authentication. Here's a
concise way to authenticate using token-based authentication, which is
recommended for security:
1. Initialize the `RestClient` with your HugeGraph server's URL.
2. Use the `LoginAPI` to log in with your admin credentials and obtain a
token.
3. Set the authentication context of your client with the obtained token.
Here's a simplified example:
```java
import org.apache.hugegraph.client.RestClient;
import org.apache.hugegraph.structure.auth.Login;
import org.apache.hugegraph.structure.auth.LoginResult;
import org.apache.hugegraph.api.auth.LoginAPI;
import org.apache.hugegraph.api.auth.TokenAPI;
public class YourTestClass {
private static String BASE_URL = "http://your_hugegraph_server.com";;
private static String GRAPH = "your_graph_name";
private static RestClient client;
public static void init() {
client = RestClient.builder(BASE_URL).build();
LoginAPI loginAPI = new LoginAPI(client, GRAPH);
Login login = new Login().name("admin").password("pa");
LoginResult result = loginAPI.login(login);
client.setAuthContext("Bearer " + result.token());
}
public static void main(String[] args) {
init();
// Your client is now authenticated and ready for API calls
}
}
```
Make sure to replace `"http://your_hugegraph_server.com"` and
`"your_graph_name"` with your actual server URL and graph name. Also, confirm
that the username and password match those expected by your server.
This setup should resolve the authentication issue. If the problem persists,
it might be beneficial to check your HugeGraph server's authentication
configuration, particularly the `auth.authenticator` property in the
`rest-server.properties` file, to ensure it's correctly set up for your
authentication method.
