详细描述

QGrpcHttp2Channel utilizes channel and call credentials. Channel credential QGrpcHttp2Channel supports SslConfigCredential key. When HTTPS is used, this key has to be explicitly specified and provide QSslConfiguration and value. The QSslConfiguration provided 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.

成员函数文档编制

[explicit] QGrpcHttp2Channel:: QGrpcHttp2Channel (const QGrpcChannelOptions & options )

QGrpcHttp2Channel constructs QGrpcHttp2Channel with options .

[override virtual noexcept] QGrpcHttp2Channel:: ~QGrpcHttp2Channel ()

销毁 QGrpcHttp2Channel 对象。

[override virtual] QGrpcStatus QGrpcHttp2Channel:: call ( QLatin1StringView method , QLatin1StringView service , QByteArrayView args , QByteArray & ret , const QGrpcCallOptions & options = QGrpcCallOptions())

重实现： QAbstractGrpcChannel::call (QLatin1StringView method, QLatin1StringView service, QByteArrayView args, QByteArray &ret, const QGrpcCallOptions &options).

Synchronously calls the RPC method and writes the result to the output parameter ret .

The RPC method name is constructed by concatenating the method and service parameters and called with the args argument. Uses options argument to set additional parameter for the call.

[override virtual] std::shared_ptr < QGrpcCallReply > QGrpcHttp2Channel:: call ( QLatin1StringView method , QLatin1StringView service , QByteArrayView args , const QGrpcCallOptions & options = QGrpcCallOptions())

重实现： QAbstractGrpcChannel::call (QLatin1StringView method, QLatin1StringView service, QByteArrayView args, const QGrpcCallOptions &options).

Asynchronously calls the RPC method.

The RPC method name is constructed by concatenating the method and service parameters and called with the args argument. Uses options argument to set additional parameter for the call. The method can emit QGrpcCallReply::finished () 和 QGrpcCallReply::errorOccurred () signals on a QGrpcCallReply returned object.

[override virtual] std::shared_ptr < QAbstractProtobufSerializer > QGrpcHttp2Channel:: serializer () const

重实现： QAbstractGrpcChannel::serializer() const .

返回新近创建的 QProtobufSerializer shared pointer.

[override virtual] std::shared_ptr < QGrpcStream > QGrpcHttp2Channel:: startStream ( QLatin1StringView method , QLatin1StringView service , QByteArrayView arg , const QGrpcCallOptions & options = QGrpcCallOptions())

重实现： QAbstractGrpcChannel::startStream (QLatin1StringView method, QLatin1StringView service, QByteArrayView arg, const QGrpcCallOptions &options).

Creates and starts a stream to the RPC method.

The RPC method name is constructed by concatenating the method and service parameters and called with the arg argument. Returns a shared pointer to the QGrpcStream . Uses options argument to set additional parameter for the stream.

调用 QGrpcStream::updateData () when the stream receives data from the server. The method may emit QGrpcStream::errorOccurred () when the stream has terminated with an error.
