如何在WebRequest中使用WSS作为前缀？

Question

我想用C＃为DiscordBot编写一个库，但是在发送消息之前，我必须向Disord Gateway发送一个WSS POST请求，该请求无法与标准WebRequest一起使用。

我尝试改用HTTPS，但是WSS是WebRequest无法理解的另一个前缀。使用WebRequest.Registerprefix（）也不起作用，但是我认为这可以在正确的界面上工作。

代码如下：

private void Identify(string token)
{
    string reqContent = "{"+
    "\"token\": \"" + token+ "\","+
    "\"properties\": {"+
    "\"$os\": \"linux\","+
    "\"$browser\": \"disco\","+
    "\"$device\": \"disco\"" +
    "},"+
    "\"compress\": true,"+
    "\"large_threshold\": 250,"+
    "\"shard\": [1, 10],"+
    "\"presence\": {"+
    "\"game\": {"+
    "\"name\": \"Cards Against Humanity\","+
    "\"type\": 0"+
    "},"+
    "\"status\": \"dnd\","+
    "\"since\": 91879201,"+
    "\"afk\": false"+
    "}"+
    "}";    //Example from discord.gg

    WebRequest req = WebRequest.Create(
    "wss://gateway.discord.gg/?v=" + gatewayVersion + "&encoding=json");  
    //Here is the Exception

    req.Method = "POST";
    var bytes = Encoding.ASCII.GetBytes(reqContent);
    req.GetRequestStream().Write(bytes, 0, bytes.Length);

    WebResponse response = req.GetResponse();
    Console.WriteLine(response.GetResponseStream().ToString());
}
