在没有用户消息的情况下将消息发送到 Discord 频道

Question

基本上我正在寻找的是找到频道名称（例如公告）并向其发送消息的某种方式。我知道如何在用户通过 discord 发送消息时或在 discord 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。

我当前的代码是这样的：

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 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 int views { get; set; }

        }

        public class Stream
        {

            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;
            }
        }
    }
}

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

如果我们只检查某个属性（通道是否存在），则没有理由包含所有的抽动响应对象。遍历 JSON 树并查找特定项目非常容易。

我已经完成了下面代码中的问题，并添加了评论供您关注，希望对您的学习有所帮助。将以下代码粘贴到控制台应用程序的 Program.cs 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;
    }
}
