MongoDbConnectionResolver implementation. Helper class that resolves MongoDB connection and credential parameters, validates them and generates a connection URI.

Description

The MongoDbConnectionResolver class allows you to create a MongoDB connection resolver that resolves MongoDB connection and credential parameters, validates them, and generates a connection URI.

Important points

  • It is able to process multiple connections to MongoDB cluster nodes.

Configuration parameters

  • connection(s):

    • discovery_key: (optional) key to retrieve the connection from IDiscovery
    • host: host name or IP address
    • port: port number (default: 27017)
    • database: database name
    • uri: resource URI or connection string with all parameters in it

  • credential(s):

    • store_key: (optional) key to retrieve the credentials from ICredentialStore

References

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

Methods

Configure

Configures the component by passing its configuration parameters.

(c *MongoDbConnectionResolver) Configure(ctx context.Context,config *cconf.ConfigParams)

  • ctx: context.Context - operation context.
  • config: *cconf.ConfigParams - configuration parameters to be set.

Resolve

Resolves a MongoDB connection URI from connection and credential parameters.

(c *MongoDbConnectionResolver) Resolve(ctx context.Context, correlationId string) (uri string, err error)

  • ctx: context.Context - operation context.
  • correlationId: string - (optional) transaction id used to trace execution through the call chain.
  • returns: (uri string, err error) - resolved URI

SetReferences

Sets references to dependent components.

(c *MongoDbConnectionResolver) SetReferences(ctx context.Context, references crefer.IReferences)

  • ctx: context.Context - operation context.
  • references: crefer.IReferences - references to locate the component dependencies.
