type UnimplementedWsServiceServer 

type UnimplementedWsServiceServer struct {

type UnsafeWsServiceServer 

type UnsafeWsServiceServer interface {
	// contains filtered or unexported methods
}

UnsafeWsServiceServer may be embedded to opt out of forward compatibility for this service. Use of this interface is not recommended, as added methods to WsServiceServer will result in compilation errors.

type WsServiceClient 

type WsServiceClient interface {
	//  会话是否存在
	ExistSession(ctx context.Context, in *SessionReq, opts ...grpc.CallOption) (*SessionRes, error)
	//  发送消息
	SendMessage(ctx context.Context, in *MessageReq, opts ...grpc.CallOption) (*Empty, error)
}

WsServiceClient is the client API for WsService service.

For semantics around ctx use and closing/ending streaming RPCs, please refer to https://pkg.go.dev/google.golang.org/grpc/?tab=doc#ClientConn.NewStream.

func NewWsServiceClient 

func NewWsServiceClient(cc grpc.ClientConnInterface) WsServiceClient

type WsServiceServer 

type WsServiceServer interface {
	//  会话是否存在
	ExistSession(context.Context, *SessionReq) (*SessionRes, error)
	//  发送消息
	SendMessage(context.Context, *MessageReq) (*Empty, error)
	// contains filtered or unexported methods
}

WsServiceServer is the server API for WsService service. All implementations must embed UnimplementedWsServiceServer for forward compatibility
