HttpConnectionResolver class Null safety

Helper class to retrieve connections for HTTP-based services abd clients.

In addition to regular functions of ConnectionResolver is able to parse http:// URIs and validate connection parameters before returning them.

Configuration parameters

  • connection:

    • discovery_key: (optional) a key to retrieve the connection from IDiscovery
    • ... other connection parameters
  • connections: alternative to connection

    • connection params 1: first connection parameters
    • ...
    • connection params N: Nth connection parameters
    • ...

References

  • \*:discovery:\*:\*:1.0 (optional) IDiscovery services

See ConnectionParams See ConnectionResolver

Example

var config = ConfigParams.fromTuples([
     'connection.host', '10.1.1.100',
     'connection.port', 8080
]);

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

var connection = connectionResolver.resolve('123',
      // Now use connection...

Methods

configure(ConfigParams config) → void
Configures component by passing configuration parameters.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
register(String? correlationId) Future
Registers the given connection in all referenced discovery services. This method can be used for dynamic service discovery.
resolve(String? correlationId) Future<ConfigParams?>
Resolves a single component connection. If connections are configured to be retrieved from Discovery service it finds a IDiscovery and resolves the connection there.
resolveAll(String? correlationId) Future<ConfigParams>
Resolves all component connection. If connections are configured to be retrieved from Discovery service it finds a IDiscovery and resolves the connection there.
setReferences(IReferences references) → void
Sets references to dependent components.
toString() String
A string representation of this object.
