I tried pdf, txt and png file url, only pdf url can't be open with browser if click the url, but trigger download.
I google this but only got how to fix, like instead with google doc or use pdf.js, or other html code.
What is the reason? the website ? Forgive me that i have no idea of website architecture.
When you get a file from a website, it has a content type sent along with it. Depending on the content type, the browser may choose to display it. For example, content type "application/pdf" might be shown in a browser, but "application/octet-stream" will be downloaded.
The raw URL on GitHub has content type "application/octet-stream" (a binary file) so that it will be downloaded.
The only way around this, since you can't change GitHub's code that sets the content type, is to get the data from JavaScript and parse it there -- by using pdf.js or something similar.

Imagine my website is hosted on GitHub Pages and has a custom domain website.com. I can access a pdf at website.com/mypdf.pdf
Is there a way where I can make it work at website.com/mypdf?
As mentioned in comments, if you are using static website hosted by a 3rd party like GitHub pages, you don't really get a lot of control over http server. I would tentatively say you cannot control URL rewrite rules on GitHub.
What you could potentially do instead is to host a page with a bit of JavaScript that would start the download on a given event (button click, page load, etc) this way you could mask your actual download URL with this html page (that by convention comes with no file extension)
UPD: and surely enough someone's been doing it already: http://lea.verou.me/2016/11/url-rewriting-with-github-pages/. The post is going on about having nice urls, but I believe file downloads implementation can be implemented similarly
Yes you should make your website with MVC structure. Make a controller and in Index action load pdf file.
Then on action calling your pdf will be loaded like that:
Students/AllResult etc
I have files stored on google cloud storage. Google provides me a URL to access this files, but when I access this URL the file is auto downloaded. I wish to know if it is possible to remove or don't allow this auto download when we access the file URL. ;)
The download feature is handled by the client.
Calling the URL for an object stored in a bucket will return the object in the body of the HTTP request, and the client will choose what to do with this data.
If you use a web browser, the choice of downloading or not a file is usually given by the header Content-Type. In general, there are some MIME types that will be displayed on the browser itself (according to Chrome help, videos, images, PDFs and web pages will be displayed directly on the browser), while others will download directly.
To modify the MIME type of the files stored in a bucket, you must change it's metadata, so the browser will behave in the way you want.
I don't find a way how to like link to a file ? Is it even possible ?
Example:
https://example.com/somefile.jpg/zip
And i would like to share that link to, so title description etc. is very desirable but I don't know where to put tags for og:url etc. since there are no meta tags at this.
That is not directly possible; we can of course not put HTML meta elements into jpeg or zip file.
But you can try and tackle this either of those two ways:
Share an HTML document instead, that returns the meta data, and triggers the actual file download via meta refresh or JavaScript. Or,
make your server return an HTML document instead of the file, only when the requesting User-Agent is the Facebook scraper.
Assume the situation, i have an UIWebView and signed in into my gmail account, i have received an e-mail with an attached pdf file. Now am clicking on the attachment link the webview will open the pdf file there itself.
At this time if am trying to read the html contents it returns NULL.
Please help me by giving an idea. Now how could i read/parse that pdf content already loaded in webview and store the data into NSString.
if you have the URL for the PDF file then directly load the URL in the WebView otherwise you have to use the NSURLRequest to download the file and then load the file from the local directory of the application. I shall be glad to provide you with the code of loading the PDF file from the local directory however I suggest you to google it.
I want to open a pdf file from a button of my GWT application. Actually to access that file I've to query the server that returns the file encoded in base64 from a JSON request.
It's possible to open that file then?
To show a pdf "file" (it's not a file, but a byte stream in http reply) you need to rely on browsers own capability to render pdf data. To do this you must either open a URL in a new window or in in an iframe. The second is probably a better option when using GWT. Docs of the GWT Frame.
// url of the pdf (must have application/pdf content-type)
Frame frame = new Frame("url");
// add the frame wherever you want
RootPanel.get().add(frame);
In order for the browser to correctly display pdf page (by invoking the pdf plugin), the url that serves the pdf data must have a header that says Content-Type: application/pdf. Check that your response has this header.
