    • create

      static StreamingHttpClient create(@Nullable URL url)
      Create a new StreamingHttpClient. Note that this method should only be used outside of the context of a Micronaut application. The returned StreamingHttpClient is not subject to dependency injection. The creator is responsible for closing the client to avoid leaking connections. Within a Micronaut application use Inject to inject a client instead.
      Parameters:
      url - The base URL
      Returns:
      The client

    • create

      static StreamingHttpClient create(@Nullable URL url, @NonNull HttpClientConfiguration configuration)
      Create a new StreamingHttpClient with the specified configuration. Note that this method should only be used outside of the context of an application. Within Micronaut use Inject to inject a client instead
      Parameters:
      url - The base URL
      configuration - the client configuration
      Returns:
      The client
