Detailed Description

The QGrpcHttp2Channel class is HTTP/2 implementation of QAbstractGrpcChannel interface.

For QGrpcHttp2Channel utilizes channel and call credentials. For channel credential QGrpcHttp2Channel supports SslConfigCredential key. When https is used, this key has to be explicitly specified and provide QSslConfiguration and value. Provided QSslConfiguration will be used to establish HTTP/2 secured connection. All keys passed as QGrpcCallCredentials will be used as HTTP/2 headers with related values assigned.

Constructor & Destructor Documentation

QGrpcHttp2Channel()

QGrpcHttp2Channel::QGrpcHttp2Channel	(	const QUrl &	url,
		std::unique_ptr< QAbstractGrpcCredentials >	credentials
	)

QGrpcHttp2Channel constructs QGrpcHttp2Channel.

Parameters

url	http/https url used to establish channel connection
credentials	call/channel credentials pair

Member Function Documentation

call() [1/2]

QGrpcStatus QGrpcHttp2Channel::call ( const QString &  method, const QString &  service, const QByteArray &  args, QByteArray &  ret  )

overridevirtual

Calls method synchronously with given serialized message args and write result of call to ret.

Note

This method is synchronous, that means it doesn't return until call is completed or aborted by timeout if it's implemented in inherited channel.

This method should not be called directly.

Parameters

[in]	method	remote method is called
[in]	service	service identified in URL path format
[in]	args	serialized argument message
[out]	ret	output bytearray to collect returned message

Returns

returns gRPC QAbstractGrpcChannel::Status code for operation

Implements QtProtobuf::QAbstractGrpcChannel.

call() [2/2]

void QGrpcHttp2Channel::call ( const QString &  method, const QString &  service, const QByteArray &  args, QtProtobuf::QGrpcAsyncReply *  ret  )

overridevirtual

Calls method asynchronously with given serialized messge args.

Result of method call is written to QGrpcAsyncReply.

Note

This method is asynchronous, that means it returns control imediately after it is called.

This method should not be called directly.

Parameters

[in]	method	remote method is called
[in]	service	service identified in URL path format
[in]	args	serialized argument message
[out]	ret	QGrpcAsyncReply that will be returned to end-point user to read data once call complete. QGrpcAsyncReply lifecycle is managed by QAbstractGrpcClient only.

See also

QGrpcAsyncReply for details

Implements QtProtobuf::QAbstractGrpcChannel.

subscribe()

void QGrpcHttp2Channel::subscribe ( QGrpcSubscription *  subscription, const QString &  service, QAbstractGrpcClient *  client  )

overridevirtual

Subscribes to server-side stream to receive updates for given method.

Note

This method should not be called directly.

Parameters

[in]	method	remote method is called
[in]	service	service identified in URL path format
[in]	args	serialized argument message
[in]	handler	callback that will be called when message recevied from the server-stream

Implements QtProtobuf::QAbstractGrpcChannel.
