Helper class used to retrieve Azure connection and credential parameters, validate them and compose a AzureFunctionConnectionParams value.

Implements: IConfigurable, IReferenceable

Description

Helper class to retrieve Azure connection and credential parameters, validate them and compose a AzureFunctionConnectionParams value.

Configuration parameters

  • connections:
    • uri: full connection uri with specific app and function name
    • protocol: connection protocol
    • project_id: is your Google Cloud Platform project ID
    • region: is the region where your function is deployed
    • function_name: is the name of the HTTP function you deployed
  • credentials:
    • auth_token: Google-generated ID token or null if using custom auth

References

  • *:discovery:*:*:1.0 - (optional) IDiscovery services to resolve connection.
  • *:credential-store:*:*:1.0 - (optional) credential stores to resolve credentials.

Fields

connectionResolver

Connection resolver.

final _connectionResolver: ConnectionResolver

credentialResolver

Credential resolver.

final credentialResolver: CredentialResolver

Instance methods

configure

Configures a component by passing its configuration parameters.

void configure(ConfigParams config)

  • config: ConfigParams - configuration parameters to be set.

resolve

Resolves connection and credential parameters and generates a single AzureFunctionConnectionParams value.

Future resolve(IContext? context) async

  • context: IContext - (optional) a context to trace execution through a call chain.
  • returns: Future(AzureFunctionConnectionParams) - receives an AzureFunctionConnectionParams value or error.

setReferences

Sets references to dependent components.

void setReferences(IReferences references)

  • references: IReferences - references to locate the component’s dependencies.

Examples

var config = ConfigParams.fromTuples([
         'connection.uri', 'http://myapp.azurewebsites.net/api/myfunction',
         'connection.app_name', 'myapp',
         'connection.function_name', 'myfunction',
         'credential.auth_code', 'XXXXXXXXXX',
     ]);

     var connectionResolver = AzureConnectionResolver();
     connectionResolver.configure(config);
     connectionResolver.setReferences(references);

     final connectionParams = await connectionResolver.resolve(Context.fromTraceId('123'));
         // Now use connection...
