uri

问题 Just wondering if anyone can help me with a problem I've come across in Java. Is there functionality within Java to produce a section of code that will open the default email application on a user's PC? (I guess almost like a fancy mailto link...) If there is - is it possible to populate fields such as the To and Subject fields? Thanks, Mike. 回答1: Desktop.mail(URI mailtoURI) is your friend! Javadoc: Launches the mail composing window of the user default mail client, filling the message fields

问题 Why should we use those, rather than ordinary ones? what's the benefits of using this: new Uri("pack://application:,,,/File.xaml"); over that: new Uri("/File.xaml", UriKind.Relative); 回答1: The first one - you can use cross-assembly by adding a assembly-name after the three commas. So, you can create a shared library with common styles and other XAML-goodness that can be shared between several assemblies. Syntax is like this: pack://application:,,,/Common;component/CommonResources.xaml where

问题 Question: I have found that java.net.URI has a create(String uri) option but the android.net.uri does not. More specifically: I am trying to grab the output of RingtoneManager's RingtonePicker and set it as the default ringtone with SetActualDefaultRingtoneUri : Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER); intent.putExtra( RingtoneManager.EXTRA_RINGTONE_TYPE ,RingtoneManager.TYPE_RINGTONE); intent.putExtra( RingtoneManager.EXTRA_RINGTONE_TITLE , "Select Tone For Rainy

问题 var baseUri = new Uri("http://localhost/"); var uri1 = new Uri(baseUri, "1"); var uri2 = new Uri(uri1, "2"); Unexpectedly, uri2 is http://localhost/2. How would I append to uri1 so it's http://localhost/1/2 intead? Does Uri do this, or do I need to fallback to strings? Incidentally, I've tried adding leading/trailing slashes almost everywhere. 回答1: "1" and "2" are "file name portion" of a url. If you make "1" to look more like directory path it will work ok "1/": var baseUri = new Uri("http:/

问题 I'm trying to validate a Uri using the Uri.TryCreate method and when I called it with an invalid string, the method returned true. Any ideas why? My code is below: private void button1_Click(object sender, EventArgs e) { Uri tempValue; if (Uri.TryCreate("NotAURL", UriKind.RelativeOrAbsolute, out tempValue)) { MessageBox.Show("?"); } } 回答1: That's a valid relative URL. An example of a invalid URI is: "http://example.com<>" If you want to allow only absolute URIs, use UriKind.Absolute . The

问题 I got an uri ( java.net.URI ) such as http://www.example.com. How do I open it as a stream in Java? Do I really have to use the URL class instead? 回答1: You will have to create a new URL object and then open stream on the URL instance. An example is below. try { URL url = uri.toURL(); //get URL from your uri object InputStream stream = url.openStream(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (URISyntaxException e) { e.printStackTrace(); }catch (IOException e) { e

问题 This question might seem stupid but, I am writing a dissertation about camera API for Android. Right now I'm looking at saving images on a SD Card, but I'm a bit confused about what Uri is and does. Does it parse the image from the camera to the imageView? Is it the path of the image? I found a tutorial, but it doesn't describe what the Uri is. The Uri in the code Uri uri; final static int MEDIA_TYPE_IMAGE = 1; uri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); public Uri getOutputMediaFileUri

问题 I'm trying to use pagination class in codeigniter and my url looks something like this: blah.com/posts/browse/page/1/item_per_page/10 is there anyway to keep the page number in the middle of url? Thanks EDIT: $this->load->library('pagination'); $uri = $this->uri->uri_to_assoc(); $page = null; $item_per_page = null; if (count($uri)) { foreach ($uri as $key => $value) { $$key = $value; } } $config['base_url'] = base_url('posts/browse/page//item_per_page/1'); $config['uri_segment'] = 4; $config[

问题 Guzzle 3 had URI templates that allowed for a request definition such as $request = $client->get(array('http://example.com{+path}{/segments*}{?query,data*}', array( 'path' => '/foo/bar', 'segments' => array('one', 'two'), 'query' => 'test', 'data' => array( 'more' => 'value' ) ))); In my case, i am looking to exploit the 'segments' , but Guzzle 5 doesn't seem to define this. Instead the closest ive come across was * $client = new Client([ * 'base_url' => [ * 'http://www.foo.com/{version}/', *
