Binary data restore when opening an image url

[XiaoFaye]

Sample code:

var config = Configuration.Default.WithDefaultLoader().WithCookies();
var context = BrowsingContext.New(config);
await context.OpenAsync("http://www.xxx.com/");
var doc = await context.OpenAsync("http://www.xxx.com/abc.jpg");          
var data = doc.Body.TextContent;

When debug into the code, I can see the binary data of the image has been converted to UTF-8 string in doc.Boday.TextContent. That means the image has been downloaded. However I can't restore the image binary data with the UTF-8 string as some data has lost during the conversion.

Is there a way that I can get the original binary data of the image? For some reason, I can't download the image using regular way.

There are two more or less direct ways in v0.9.9:

1. Provide a custom document creator that can deal with the content
2. Insert an HTTP requester middleware to get the data

The first one is what is biting you right now. As there is no document creator for images, it will use a plain text document. That is obviously not what you want. Unfortunately, in v0.9.9 the document factory was not opened up yet, so the only way to access it is via reflection...

That leaves us with option 2. Here we could, e.g., create an HTTP requester wrapper, or a DocumentLoader wrapper. The latter can be easily injected into a configuration and has a virtual method DownloadAsync. This one is used when downloading the document and gives you the full request and response.

Hope this helps!

Thanks for the idea, where I can find an example for using HTTP requester wrapper, or a DocumentLoader wrapper?
