测试Discord邀请链接是否无效? [英] Testing if Discord invite link is invalid?

问题描述

我正在尝试制作一个用于测试Discord邀请链接并检查它们是否无效的应用程序.但是，我不知道该怎么做.

I am trying to make an application that tests Discord invite links and checks if they are invalid or valid. However, I do not know how to do this.

推荐答案

使用GET请求发送到邀请端点.

Use a GET request to the invite endpoint.

请求:

GET: https://discordapp.com/api/invite/obviously-invalid-invite-code

响应(HTTP状态404):

Response (HTTP status 404):

{
    "code": 10006,
    "message": "Unknown Invite"
}

---

您可以通过对终端使用 WebRequest 调用，并捕获在API返回404时抛出的 WebException 来实现.

You can do this by using a WebRequest call to the endpoint, and catching a WebException that gets thrown when the API returns 404.

try
{
    WebRequest request = WebRequest.Create("https://discordapp.com/api/invites/obviously-invalid-invite-code");
    request.Method = "GET";

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();

    if (response.StatusCode == HttpStatusCode.OK) // and possibly other checks in the response contents
    {
        Console.WriteLine("Invite link is valid");
    }
} 
catch (WebException wex)
{
    if (((HttpWebResponse)wex.Response).StatusCode == HttpStatusCode.NotFound)
    {
        Console.WriteLine("Invite link is invalid");
    }
    // You may need to account for other 400/500 statuses
    else throw wex;
}
