How to link files directly from Github (raw.github.com)

问题

Are we allowed to link files directly from Github ?

<link rel="stylesheet" href="https://raw.github.com/username/project/master/style.css"/>
<script src="https://raw.github.com/username/project/master/script.js"></script>

I know this is allowed on Google Code. This way I don't have to worry about updating a local file.

回答1:

Yes. It's even update safe unless someone changes history in git and forces a push.

In other words the content is versioned.

回答2:

The great service RawGit was already mentioned, but I'll throw another into the ring: GitCDN.link

Benefits:

Lets you link to specific commits, as well as auto-get the latest (aka master)
Incurs no damage from high traffic volumes; RawGit asks that it's dev.rawgit.com links be only used during development, where as GitCDN give you access to the latest version, without the danger of the servers exploding
Give you the option of auto minifying your HTML, CSS and JavaScript, or serving it as written (https://min.gitcdn.link).
Adds compression (GZip)
Adds all the correct headers (Content-Type, cache-control, e-tag, etc)

Full disclosure, I'm a project maintainer at GitCDN.link

You can use external server rawgithub.com. Just remove a dot between words 'raw' and 'github' https://raw.github.com/.. => https://rawgithub.com/ and use it. More info you find in this question.

However, according to the rawgithub website it will be shutting down at the end of October 2019.

You need carry out the following steps

Get the raw url of the file from github. Which is something like https://raw.githubusercontent.com/username/folder/example.css
Visit http://rawgit.com/. Paste the git url above in the input box. It will generate two url's, one for development and other for production purpose.
Copy any one of them and you are done.

The file will act as a CDN. You can also use gist urls.

回答5:

You can link directly to raw files, but it's best not to do it since the raw files always get sent with a plain/text header and can cause loading problems.

回答6:

Add a branch your project using the name "gh-pages" and then you'll (shortly after branching) be able to use a direct URL such as https://username.github.io/project/master/style.css (using your URL, and assuming "style.css" is a file in the "master" folder in the root of your "project" repository...and that your Github account is "username").

回答7:

GitHub Pages: https://yourusername.github.io/script.js
GitHub repo raw files: https://github.com/yourusername/yourusername.github.io/blob/master/script.js

Use GitHub Pages, DO NOT use raw files.

Reason: GitHub Pages are based on CDN, raw files are not. Accessing raw files will directly hit on GitHub servers and increase server load.

After searching for this same functionality, I ended up writing my own PHP script to act as a proxy. The trouble I kept running into is even when you get the RAW version/link from Github and link to it in your own page, the header sent over was 'text/plain' and Chrome was not executing my JavaScript file from Github. I also didn't like the other links posted for using third party services because of the obvious security/tampering issues possible.

So using this script, I can pass over the RAW link from Github, have the script set the correct headers, and then output the file as if it were coming from my own server. This script can also be used with a secure application to pull in non-secure scripts without throwing SSL errors warning of "Non-secure links used".

Linking:

<script src="proxy.php?link=https://raw.githubusercontent.com/UserName/repo/master/my_script.js"></script>

proxy.php

<?php

# This script can take two URL variables
# 
# "type"
#   OPTIONAL

# First we need to set the headers for the output file

    switch($_GET['type']){
        case 'css':

            break;

        case 'js':
            header('Content-Type: text/javascript');
            break;

        case 'json':
            header('Content-Type: application/json');

        case 'xml':
            header('Content-Type: text/xml');
            break;

        default:
            header('Content-Type: text/plain');
            break;
    }

# Otherwise, try and determine what file type should be output by the file extension from the link
}else{
    # See if we can find a file type in the link specified and set the headers accordingly

    # If css file extension is found, then set the headers to css format
    if(strstr($_GET['link'], '.css') != FALSE){
        header('Content-Type: text/css');

    # If javascript file extension is found, then set the headers to javascript format
    }elseif(strstr($_GET['link'], '.js') != FALSE){
        header('Content-Type: text/javascript');

    # If json file extension is found, then set the headers to json format
    }elseif(strstr($_GET['link'], '.json') != FALSE){
        header('Content-Type: application/json');

    # If rss file extension is found, then set the headers to rss format
    }elseif(strstr($_GET['link'], '.rss') != FALSE){
        header('Content-Type: application/rss+xml; charset=ISO-8859-1');

    # If css xml extension is found, then set the headers to xml format
    }elseif(strstr($_GET['link'], '.xml') != FALSE){
        header('Content-Type: text/xml');

    # If we still haven't found a suitable file extension, then just set the headers to plain text format
    }else{
        header('Content-Type: text/plain');
    }
}

# Now get the contents of our page we're wanting
$contents = file_get_contents($_GET['link']);

# And finally, spit everything out
echo $contents;
?>

If your webserver has active allow_url_include, GitHub serving the files as raw plain/text is not a problem since you can include the file first in a PHP script and modify its Headers to the proper MIME type.

回答10:

Just go to the github file path and click on the raw button, you'll be redirected to the raw path for the file. Copy the URL and use it in your DOM.
