.Net Core 3.0 尝试从 url 获取 html 内容时此错误页面可能包含敏感错误

Question

就像我说的，我试图从 URL 获取一些 HTML 内容，但它告诉我“此错误页面可能包含敏感错误”，我该如何解决？我的代码：

try
{
    string siteContent = string.Empty;
    string url = "https://www.antalyaeo.org.tr/tr/nobetci-eczaneler";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.AutomaticDecompression = DecompressionMethods.GZip;
    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())   
    using (Stream responseStream = response.GetResponseStream())               
    using (StreamReader streamReader = new StreamReader(responseStream))        
    {
        siteContent = streamReader.ReadToEnd(); 
    }
    return siteContent;
}

catch (WebException webex)
{
    WebResponse errResp = webex.Response;
    using (Stream respStream = errResp.GetResponseStream())
    {
        StreamReader reader = new StreamReader(respStream);
        string text = reader.ReadToEnd();
        return text;

    }
}

错误信息：

This error page might contain sensitive information because ASP.NET is configured to show verbose error messages using <customErrors mode="Off"/>. Consider using <customErrors mode="On"/> or <customErrors mode="RemoteOnly"/> in production environments.-->

我尝试了什么：当我搜索 google 和 Whosebug 时，我看到他们说 make customError="False" 或者有点像 system.web / web.config文件在我的项目中。我该如何解决？谢谢

您需要添加user-agent否则服务器似乎拒绝您的请求，例如：

HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
request.AutomaticDecompression = DecompressionMethods.GZip;
request.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
using (HttpWebResponse response = (HttpWebResponse) request.GetResponse())
