在没有用户消息的情况下向 Discord 频道发送消息

扎克·阿奈特

基本上，我正在寻找的是某种方式来查找频道名称（例如公告）并向其发送消息。我知道如何在用户通过不和谐发送消息时或在不和谐中发生事件时发送消息

e.Server.FindChannels("Channel Name").FirstorDefault;
await channel.sendmessage(string.Format("Message"))

但我希望在 Twitch 上发生事件时发送消息。

我目前的代码是这样的：

TwitchAPIexample.RootObject json = TwitchAPIexample.BuildConnect();

    if (TwitchAPIexample.TwitchLive(json))
    {
        var channel = client.GetChannel("announcements"); //Where I need to get channel
        //Where I need to send message to channel
    }

我从中提取代码的文件：

using System.Net;
using System.IO;
using Newtonsoft.Json;

namespace MyFirstBot.Plugins
{
    public class TwitchAPIexample
    {

        private const string url = "https://api.twitch.tv/kraken/streams/channel";

        public bool isTwitchLive = true;

        public static RootObject BuildConnect()
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

            request.Method = "Get";
            request.Timeout = 12000;
            request.ContentType = "application/json";
            request.Headers.Add("authorization", "Token");

            using (System.IO.Stream s = request.GetResponse().GetResponseStream())
            {
                using (StreamReader sr = new System.IO.StreamReader(s))
                {
                    var jsonResponse = sr.ReadToEnd();
                    RootObject r = JsonConvert.DeserializeObject<RootObject>(jsonResponse);
                    return r;
                }
            }
        }


        public class Preview
        {
            public string small { get; set; }
            public string medium { get; set; }
            public string large { get; set; }
            public string template { get; set; }
        }

        public class Channel
        {
            public bool mature { get; set; }
            public string status { get; set; }

            public string name { get; set; }
            public string created_at { get; set; }
            public string updated_at { get; set; }
            public bool partner { get; set; }
            public string logo { get; set; }
            public string video_banner { get; set; }
            public string profile_banner { get; set; }
            public object profile_banner_background_color { get; set; }
            public string url { get; set; }
            public int views { get; set; }
            public int followers { get; set; }
        }

        public class Stream
        {
            public long _id { get; set; }
            public string game { get; set; }
            public int viewers { get; set; }
            public int video_height { get; set; }
            public int average_fps { get; set; }

            public string created_at { get; set; }
            public bool is_playlist { get; set; }
            public Preview preview { get; set; }
            public Channel channel { get; set; }
        }

        public class RootObject
        {
            public Stream stream { get; set; }
        }

        public static bool TwitchLive(RootObject stream)
        {
            TwitchAPIexample twitch = new TwitchAPIexample();
            string test = stream.stream.ToString();
            if(test == null)
            {
                twitch.isTwitchLive = false;
                return false;
            }
            else if(test != null & twitch.isTwitchLive == false)
            {
                twitch.isTwitchLive = true;
                return true;
            }
            else
            {
                return false;
            }
        }
    }
}

你只需要搜索频道，图书馆的文档在这里：http ://rtd.discord.foxbot.me/

如果我们只检查某个属性（通道是否处于活动状态），则没有理由包含所有 twitch 响应对象。遍历 JSON 树并查找特定项非常容易。

我已经完成了下面代码中的问题，并添加了注释供您参考，希望它可以帮助您学习。将以下代码粘贴到Program.cs控制台应用程序中。

static void Main(string[] args)
{
    DiscordClient client = null;
    // initialize client etc here.

    string twitchStreamId = "";
    string twitchApiKey = "";
    string discordServerName = "";
    string discordChannelName = "";

    // find discord channel
    var server = client.FindServers(discordServerName).FirstOrDefault();
    var channel = server.FindChannels(discordChannelName, ChannelType.Text).FirstOrDefault();

    var lastTwitchStatus = CheckTwitchStatusIsOnline(twitchStreamId, twitchApiKey);

    // send a message on startup always
    SendDiscordChannelMessage(channel, lastTwitchStatus);

    while (true)
    {
        // check the status every 10 seconds after that and if the status has changed we send a message
        Thread.Sleep(10000);

        var status = CheckTwitchStatusIsOnline(twitchStreamId, twitchApiKey);

        // if the status has changed since the last time we checked, send a message
        if (status != lastTwitchStatus)
            SendDiscordChannelMessage(channel, status);

        lastTwitchStatus = status;
    }
}

private static void SendDiscordChannelMessage(Channel channel, bool twitchIsOnline)
{
    channel.SendMessage(twitchIsOnline ? "Twitch channel is now live!!" : "Twitch channel is now offline :(");
}

private static bool CheckTwitchStatusIsOnline(string streamId, string twitchApiKey)
{
    // send a request to twitch and check whether the stream is live.
    var url = "https://api.twitch.tv/kraken/streams/" + streamId;
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "GET";
    request.Timeout = 12000;
    request.ContentType = "application/json";
    request.Headers.Add("authorization", twitchApiKey);

    using (var sr = new StreamReader(request.GetResponse().GetResponseStream()))
    {
        var jsonObject = JObject.Parse(sr.ReadToEnd());
        var jsonStream = jsonObject["stream"];

        // twitch channel is online if stream is not null.
        var twitchIsOnline = jsonStream.Type != JTokenType.Null;
        return twitchIsOnline;
    }
}
