I have a public URL for an iCloud file, how can I get the DIRECT link to download in iOS? - html

I am able to generate public URLs for iCloud files. e.g. https://www.icloud.com/documents/dl/?p=3&t=BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
Accessing such a URL from a browser, I see a landing page, and shorty afterwards the file downloads automatically. Fine.
However, I want to be able to download this file from my iOS app (with NSURLConnection). How can I do this? Maybe...
a) process the html headers to somehow determine the direct URL?
b) intercept the redirect/refresh that triggers the download on a browser?
c) somehow imitate a browser in order to trigger a download?
Thanks
PS. please give me the idiot's answer- I'm clueless about html etc.
Here is the html response I'm getting for the indirect URL above:

As of July 2012, the following seems to work. But there's no guarantee that apple won't change their scheme for generating these, and it's possible that they would regard this as a private API and reject your app. So use at your own risk.
The URL has two important parameters, p and t. The first seems to identify a server, while the second identifies the actual file. The direct download link is made by plugging these values into this URL:
https://p[p]-ubiquityws.icloud.com/ws/file/[t]
Looking at your example:
https://www.icloud.com/documents/dl/?p=3&t=BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
p is 3, and t is BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA. So your direct download link would be
https://p3-ubiquityws.icloud.com/ws/file/BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
Whenever I've published a link to iCloud, p has been 01; so it's possible that you might need to zero-pad your value in which case your URL would be
https://p03-ubiquityws.icloud.com/ws/file/BAKsXkcDP-p8sdTS8NgBLWRQxE281oe4hogA
It would be great to know whether that's necessary.

In iCloud Drive / iOS8 the links are different, but you can still get a direct link to the files.

Save the text between '?u=' and '&uk=' as a NSMutableString
Save the information after 'uk=' and 'f=' as NSStrings

It looks like the heavy lifting is done by the file referenced there:
https://www.icloud.com/applications/documents/download/en-us/1FCS22.32292/javascript-packed.js
I'd start there looking for the file name etc.

HTML Filepicker without sending file itself - only filepath [duplicate]

How can I create a directory chooser in html page.
If I use input file element I can select file only, but I need to select directory instead.
I need to do this beacause the user should select a right path inside his computer.
Any solutions ?
Try this, I think it will work for you:
<input type="file" webkitdirectory directory multiple/>
You can find the demo of this at https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3 ,
and if you need further information you can find it
here.
Can't be done in pure HTML/JavaScript for security reasons.
Selecting a file for upload is the best you can do, and even then you won't get its full original path in modern browsers.
You may be able to put something together using Java or Flash (e.g. using SWFUpload as a basis), but it's a lot of work and brings additional compatibility issues.
Another thought would be opening an iframe showing the user's C: drive (or whatever) but even if that's possible nowadays (could be blocked for security reasons, haven't tried in a long time) it will be impossible for your web site to communicate with the iframe (again for security reasons).
What do you need this for?
As of 2022 there is now a directory picker API:
https://developer.mozilla.org/en-US/docs/Web/API/Window/showDirectoryPicker
async function getDir() {
const dirHandle = await window.showDirectoryPicker();
// run code for dirHandle
}
In case if you are the server and the user (e.g. you are creating an app which works via browser and you need to choose a folder) then try to call JFileChooser from the server when some button is clicked in the browser
JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new java.io.File("."));
chooser.setDialogTitle("select folder");
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
chooser.setAcceptAllFileFilterUsed(false);
This code snipped is from here
This is my solution. It is the same as the above answers but you should notice that webkitdirectory = "true".
<input id="design" type="file" webkitdirectory = "true" directory/>
I did a work around. I had a hidden textbox to hold the value. Then, on form_onsubmit,
I copied the path value, less the file name to the hidden folder. Then, set the fileInput box to "". That way, no file is uploaded.
I don't recall the event of the fileUpload control. Maybe onchange. It's been a while. If there's a value, I parse off the file name and put the folder back to the box. Of, course you'd validate that the file as a valid file.
This would give you the clients workstation folder.
However, if you want to reflect server paths, that requires a whole different coding approach.
This isn't provided by HTML because of the security risk. <input type='file' /> is closest, but not what you are looking for.
If you're still using IE11 on Windows 10, you may try this example that uses an ActiveX control to achieve what you want.
Again if the OS is Windows, you can use VB scripts to access the core control files to browse for a folder.
If you do not have too many folders then I suggest you use if statements to choose an upload folder depending on the user input details.
E.g.
String user= request.getParameter("username");
if (user=="Alfred"){
//Path A;
}
if (user=="other"){
//Path B;
}

Href without http(s) prefix

I just have created primitive html page. Here it is: example
And here is its markup:
www.google.com
<br/>
http://www.google.com
As you can see it contains two links. The first one's href doesn't have 'http'-prefix and when I click this link browser redirects me to non-existing page https://fiddle.jshell.net/_display/www.google.com. The second one's href has this prefix and browser produces correct url http://www.google.com/. Is it possible to use hrefs such as www.something.com, without http(s) prefixes?
It's possible, and indeed you're doing it right now. It just doesn't do what you think it does.
Consider what the browser does when you link to this:
href="index.html"
What then would it do when you link to this?:
href="index.com"
Or this?:
href="www.html"
Or?:
href="www.index.com.html"
The browser doesn't know what you meant, it only knows what you told it. Without the prefix, it's going to follow the standard for the current HTTP address. The prefix is what tells it that it needs to start at a new root address entirely.
Note that you don't need the http: part, you can do this:
href="//www.google.com"
The browser will use whatever the current protocol is (http, https, etc.) but the // tells it that this is a new root address.
You can omit the protocol by using // in front of the path. Here is an example:
Google
By using //, you can tell the browser that this is actually a new (full) link, and not a relative one (relative to your current link).
I've created a little function in React project that could help you:
const getClickableLink = link => {
return link.startsWith("http://") || link.startsWith("https://") ?
link
: `http://${link}`;
};
And you can implement it like this:
const link = "google.com";
<a href={getClickableLink(link)}>{link}</a>
Omitting the the protocol by just using // in front of the path is a very bad idea in term of SEO.
Ok, most of the modern browsers will work fine. On the other hand, most of the robots will get in trouble scanning your site. Masjestic will not count the flow from those links. Audit tools, like SEMrush, will not be able to perform their jobs

Referencing images stored in object storage containers (Wirecloud) from img tag

We want to develop a widget to upload images to containers. This is a very well documented task:
1.- Object Storage Tutorial
2.- Fireware-Wiki
3.- OpenStack Object Storage Docs (Swift)
With all this you can manage to get (download), upload, delete files in a container. This is relatively clear.
On the other hand, we want to develop another widget to display images stored in a container. I think in something like this to show them:
<img src="public_object_url"/>
But I do not know how to do that. Where I get this public URL? Is there a public URL? Is it get in some step during the uploading process?
I am a bit lost how to do that. Any help would be highly appreciated.
Thanks in advance.
EDIT 1
We get blocked displaying images once they are downloaded.
A look inside "img" tags shows this:
what is the string returned by URL.createObjectURL(). If we look inside this link, the browser displays this:
We have decoded the string coming in the property "value" and the image is there!
To get the image from the object storage server we used a very similar code that the one used in the operator Álvaro recommended.
objectstorage.getFile( containerName,
reports[i].urlImagen,{
token: token,
onSuccess: onGetFileSuccess.bind(null, i),
onFailure: onGetFileFailure
});
function onGetFileSuccess(index, picture){
downloadedPicsCont--;
reports[index].urlImagen = URL.createObjectURL(picture);
if(!(downloadedPicsCont > 0)){
MashupPlatform.wiring.pushEvent('reports_output', JSON.stringify(reports));
}
}
The picture variable has the following structure, which seems to be ok too.
What is it happening?
EDIT 2
Finally, we found the reason. We were downloading images that were created directly from the cloud and not with objectStorageAPI. In you upload images from the cloud, when you download them you get them inside cdmi objects so the URL.createObjectURL doesn't not work as expected. In the other hand, if you upload them using objectStorageAPI, when downloading them, they come in raw format, so the method works correctly.
As far as I know, FIWARE Object Storage needs authentication, so there are no such public URL. But... you can download the image using your credentials and then use the URL.createObjectURL method for getting an URL usable in the src attribute of the img element.
It's a bit old, but you can use this operator as reference.

Widget object is undefined in Dashcode

I'm using Dashcode for a mobile Safari web application and from the documentation (https://developer.apple.com/library/archive/documentation/AppleApplications/Conceptual/Dashcode_UserGuide/Contents/Resources/en.lproj/MakingaWidgetwithDashcode/MakingaWidgetwithDashcode.html), it appears that I should be able to access an object called "widget".
However, when I tried, I get the error message saying that widget is undefined. I've also tried "window.widget" and it gives me the same error.
What's going on?
I'd like to make a text in my application a clickable link to open a URL using openURL (like the example given at the URL above).
You use widget.xxx to access things inside and outside you widget.
So to access curl and the Mac and get some data from Yahoo you do as follows
var yahoorate = widget.system("/usr/bin/curl 'http://download.finance.yahoo.com/d/quotes.csv?s=EUR" + interim0 + "=X&f=l1'", null).outputString;
to get a preference key value, stored in the widgets plist when you install on a mac
globalPreferenceValue = widget.preferenceForKey(null, "your-key");
i think in the question ask (below) we are checking to see if we are in a widget and then preparing a transition to the back of the widget.
if (window.widget) {
widget.prepareForTransition("ToBack");
}
this is how i set a preference so it is stored between system reboots (you use a get preference to retrieve them)
widget.setPreferenceForKey(2,"ratePrecision");
and this is how you create a link to open in a browser not the widget
<a onclick=" + "widget.openURL('http://www.wf.com/private/?ID=636');" + "><span id=company-info>click here</span></a>
These are all rel working examples from widgets i have built. Hope it helps. I found it useful to download widgets that performed similar functions to ones i wanted and then as well as installing them opening them as projects, you can import, and then you can see all the code.
Ok, this worked...hope it will help someone else...
window.location = "http://www.apple.com";
