Save WebResponse as txt

Question

I'm looking for a method equivalent to Request.SaveAs in WebResponse. But I can't find it.

I want to store in txt file the headers and the body of a webresponse.

Do you know any technique to achieve it?

Answer 1

There's no builtin way, but you can simply use the GetResponseStream method to get the responce stream and save it to a file.

Example:

WebRequest myRequest = WebRequest.Create("http://www.example.com");
using (WebResponse myResponse = myRequest.GetResponse())
using (StreamReader reader = new StreamReader(myResponse.GetResponseStream()))
{
    // use whatever method you want to save the data to the file...
    File.AppendAllText(filePath, myResponse.Headers.ToString());
    File.AppendAllText(filePath, reader.ReadToEnd());
}

Nonetheless, you can wrap it into an extension method

WebRequest myRequest = WebRequest.Create("http://www.example.com");
using (WebResponse myResponse = myRequest.GetResponse())
{
    myResponse.SaveAs(...)
}

...

public static class WebResponseExtensions
{
    public static void SaveAs(this WebResponse response, string filePath)
    {
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            File.AppendAllText(filePath, myResponse.Headers.ToString());
            File.AppendAllText(filePath, reader.ReadToEnd());
        }
    }
}
