Question

我正在查看grpc示例，但我不理解该示例。有人可以向我解释吗？

示例位于：https://github.com/grpc/grpc-go/blob/master/examples/features/cancellation/server/main.go#L52

func (s *server) BidirectionalStreamingEcho(stream pb.Echo_BidirectionalStreamingEchoServer) error {
    for {
        in, err := stream.Recv()
        if err != nil {
            fmt.Printf("server: error receiving from stream: %v\n", err)
            if err == io.EOF {
                return nil
            }
            return err
        }
        fmt.Printf("echoing message %q\n", in.Message)
        stream.Send(&pb.EchoResponse{Message: in.Message})
    }
}

有人可以解释一下执行的过程吗，怎么称呼它？谢谢。

Answer 1

客户端调用方法

?>
<style type="text/css">
.img_div > img {
    height: 100px;
    width: 100px;
}
</style>
<?php
$sql = "SELECT * FROM items WHERE category LIKE '%$search%'";
$result = mysqli_query($con,$sql);
while ($row = mysqli_fetch_array($result)) {
    echo "<div class='img_div'>";
    echo "<img src='img/".$row['image']."'>";
    echo "<p>" . $row['description']."</p>";
    echo "<p>" . $row['category']."</p>";
    echo "</div>";
}

因此服务器将开始呼叫stream, err := c.BidirectionalStreamingEcho(ctx)
