How can I get html code that is shown in a browser programmatically?
问题
使用.NET，我如何以编程方式获取在浏览器中显示的HTML代码（并可以通过Chrome或Opera的“另存为”命令保存的代码）？
使用HtmlDocument.Load()或wget无济于事 - 我将得不到我想要的。
请参阅此处的讨论。
编辑
不幸的是，.Net WebClient（或者是新的.Net.Http.HttpClient）类并没有帮助（请参阅bdcoder的答案）。我得到了与HtmlDocument.Load()或wget相同的结果。不是浏览器保存的HTML代码。
let myHtml =
async
{
let client = new System.Net.Http.HttpClient()
let! responseBody =
client.GetStringAsync("https://www.kodis.cz/lines/region?tab=232-293")
|> Async.AwaitTask
return responseBody
} |> Async.RunSynchronously

Using .NET, how can I get the html code that is shown in a browser (and that can be saved from browsers such as Chrome or Opera through Save As commands) programmatically?
Using HtmlDocument.Load() or wget is to no avail - I will not get what I want.
See also the discussion here.
EDIT
Unfortunatelly the .Net WebClient (or rather the new .Net.Http.HttpClient) class did not help (see the answer by bdcoder). I got the same result as with HtmlDocument.Load() or wget. Not the html code that the browsers save.
let myHtml =
async
{
let client = new System.Net.Http.HttpClient()
let! responseBody =
client.GetStringAsync("https://www.kodis.cz/lines/region?tab=232-293")
|> Async.AwaitTask
return responseBody
} |> Async.RunSynchronously

如果您查看浏览器开发工具的网络面板，您可以看到JavaScript正在调用以获取PDF数据的终端点。您可以使用HttpClient来请求相同的数据，然后解析JSON以获取PDF链接。
