I'm making a simple website scraper to retrieve party names of supreme court cases(this is public information) in C# like in this sample link: https://www.supremecourt.gov/search.aspx?filename=/docket/docketfiles/html/public/19-8334.html
C# Code:
private static async void GetHtmlAsync(String docket)
{
var url = "https://www.supremecourt.gov/search.aspx?filename=/docket/docketfiles/html/public/19-8334.html";
var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.UserAgent.ParseAdd("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36 OPR/71.0.3770.234");
var html = await httpClient.GetStringAsync(url);
var htmlDocument = new HtmlAgilityPack.HtmlDocument();
htmlDocument.LoadHtml(html);
Console.WriteLine();
}
The problem is that whenever I run this, it successfully gives back the whole HTML file but without the data I need which is in enclosed in the element.
In browser:
In Runtime:
I don't know why but you should get proper response.
Try following you might get the answer.
var html = httpClient.GetAsync(url).GetAwaiter().GetResult();
