__construct(string $hostname, array $opts, Channel $channel = null, array $interceptors = [])

Parameters

string $hostname
array $opts
  • 'update_metadata': (optional) a callback function which takes in a metadata array, and returns an updated metadata array
    • 'grpc.primary_user_agent': (optional) a user-agent string
Channel $channel An already created Channel object (optional)
array $interceptors EXPERIMENTAL Interceptors used to intercept RPC invocations before a call starts. Please note that implementations of {see \Google\ApiCore\Transport\Grpc\UnaryInterceptorInterface} are considered deprecated and support will be removed in a future release. To prepare for this, please take the time to convert UnaryInterceptorInterface implementations over to a class which extends {see \Grpc\Interceptor}.

Parameters

array $config { Config options used to construct the gRPC transport.

@type array $stubOpts Options used to construct the gRPC stub. @type Channel $channel Grpc channel to be used. @type Interceptor[]|UnaryInterceptorInterface[] $interceptors EXPERIMENTAL Interceptors used to intercept RPC invocations before a call starts. Please note that implementations of {see \Google\ApiCore\Transport\Grpc\UnaryInterceptorInterface} are considered deprecated and support will be removed in a future release. To prepare for this, please take the time to convert UnaryInterceptorInterface implementations over to a class which extends {see \Grpc\Interceptor}. }
