使用 C# HttpWebRequest 向 TikTok 发送请求的问题

Question

I seem to be having issues just making a basic request to the TikTok homepage using the HttpWebRequest module in C#. Here is my code.

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://tiktok.com");

        using (HttpWebResponse response = (HttpWebResponse)(request.GetResponse()))
        {
            Console.WriteLine("Done");
        }

When I do this, the program hangs for a while, then I get a System.Net.WebException detailed below. I've tried setting user agents and timeouts but both don't seem to work. Any help on this would be appreciated.

System.Net.WebException HResult=0x80131509 Message=The underlying connection was closed: An unexpected error occurred on a receive. Source=System StackTrace: at System.Net.HttpWebRequest.GetResponse() in f:\dd\NDP\fx\src\net\System\Net\HttpWebRequest.cs:line 2293 at Live.Program.Main(String[] args) in E:\git\batch\live\Program.cs:line 733

This exception was originally thrown at this call stack: System.Net.Sockets.NetworkStream.Read(byte[], int, int) in NetworkStream.cs

Inner Exception 1: IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Inner Exception 2: SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I'm not entirely sure why, but once you do

request.UserAgent=".NET Framework Test Client";

before getting the response, the problem goes away. I tried with different User-Agent headers but I always get the timeout. Only .NET Framework Test Client works for me. I hope that helps you at least a bit.
