如何制作WatiN内部http请求？

Question

just wonder whether it's possible to make an internal extra request to an image without using separate code. eg,

var browser = new IE();
string url = "https://www.google.com/"
browser.GoTo(url);

// extract http://www.google.com/images/logos/ps_logo2.png 
//using a http request using browser ?

browser.Images wont let me save the image :|, how can I make an external request to get the image ?

Answer 1

如果您已经知道映像的URL，则可以使用System.Net命名空间中的WebClient类。

byte[] image = new WebClient().DownloadData("https://www.google.com/images/logos/ps_logo2.png");

Answer 2

Maybe these steps work:

• Find the image on the page:

var image = browser.Image(Find.First())

• Get the href and navigate to it

browser.GoTo(image.href);

• Get a screenshot of the page:

var screenshot= new UtilityClasses.CaptureWebPage(_browser).CaptureWebPageImage(false, false, 100);

• And then trim the screenshot to the size of the image. To get the Height and Width of the image you need the call

var width = image.Style.GetAttributeValue("width");
var height= image.Style.GetAttributeValue("height");

• Now you can create a new Image with the correct height and width.
