我想集成Socketio django redis和nodejs。我的问题是我不知道如何为两个已登录的用户创建房间。

说,例如,用户A已登录,而用户B在20分钟后登录,则用户B单击用户A的聊天室时,应自动与用户A加入会议室。

您应该将您的房间名称保存在数据库中,然后当用户B登录或单击房间时,他/她将使用该房间名称加入。我更喜欢使用随机生成的字符串作为房间名称。

keyword

但是,如果您不想在socket.io上使用房间和名称空间,则可以处理已登录并在连接时映射它们

private static void Main()
{
    var defaultIndex = "my_index";
    var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));

    var settings = new ConnectionSettings(pool, (b, s) => 
        new JsonNetSerializer(b, s, contractJsonConverters: new JsonConverter[] { new RegionInfoConverter() })
        )
        .DefaultIndex(defaultIndex);

    var client = new ElasticClient(settings);

    if (client.IndexExists(defaultIndex).Exists)
        client.DeleteIndex(defaultIndex);

    var createIndexResponse = client.CreateIndex(defaultIndex, c => c
        .Settings(s => s
            .NumberOfShards(1)
            .NumberOfReplicas(0)
        )
        .Mappings(m => m
            .Map<MyEntity>(mm => mm
                .AutoMap()
                .Properties(p => p
                    .Keyword(k => k
                        .Name(n => n.RegionInfo)
                    )
                )
            )
        )
    );

    var indexResponse = client.Index(new MyEntity 
    {
        RegionInfo = RegionInfo.CurrentRegion
    }, i => i.Refresh(Refresh.WaitFor));
}

public class MyEntity
{
    public RegionInfo RegionInfo { get; set; }
}

public class RegionInfoConverter : JsonConverter
{
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        if (value == null)
        {
            writer.WriteNull();
            return;
        }

        writer.WriteValue(((RegionInfo)value).Name);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        if (reader.TokenType == JsonToken.Null)
            return null;

        if (reader.TokenType != JsonToken.String)
            throw new JsonSerializationException($"Cannot deserialize {nameof(RegionInfo)} from {reader.TokenType}");

        return new RegionInfo((string)reader.Value);
    }

    public override bool CanConvert(Type objectType)
    {
        return typeof(RegionInfo) == objectType;
    }
}
