Hi,
I want to create a little browser, which should also be able to save images.
I managed to implement a webview where I can save the images via a long
click context menu/HitTestResult. So when I get the URL of an image, I do
something like this:
URL url = new URL(yourImageUrl);
InputStream is = (InputStream) url.getContent();
byte[] buffer = new byte[8192];
int bytesRead;
ByteArrayOutputStream output = new ByteArrayOutputStream();
while ((bytesRead = is.read(buffer)) != -1) {
output.write(buffer, 0, bytesRead);
}
then put the output.toByteArray() into a FileOutputStream;
For "normal" sites this works fine, images are stored on the sdcard.
But I still don't know how to download an image of a site which requires
some kind of authentication. For example, I enter the site and input a
username/password into a form (some server side language like PHP), which
brings me to some pictures. The webview has no problem in logging in and
displaying everything. But I can't save images, since the authentication -
which is present in the webview - is *not* present in my image saving
mechanism.
With the above code I simply get a FileNotFoundException on the
URL.getContent(). Then I tried to use HttpClient and HttpGet/HttpResponse,
where the response is always code 403.
My question: How can I access/download/authenticate to get images of
protected areas (may it be through server side language or basic
authentication).
I mean... it's all there, displayed correctly and authenticated in the
WebView :-( But there's no connection between the content of the WebView
and my URL/Http Request downloading efforts.
So, the webview already has all the information of the authentication. But
when I set up a HttpClient for Downloading, I either have to
- fetch the right session cookies from the WebView (but HOW can *I *know
what cookies for which URLS have been added to the webview, when there's
no getAllCookies() method but just a getCookie(String url) method)?
- for basic authentication, get the Username & password, when I don't know
the realm of the website?
Can the webview somehow share it's authentication state (easily)?
