How to download files from 3QSDN?
The first thing you need to do before downloading any file from 3QSDN is to get the download URI (Uniform Resource Identifier) from the API. The download URI is a unique link that points to the file you want to download. To get the download URI, you need to have two things:
Your project ID and file ID. You can find these IDs on your 3QSDN dashboard or in the URL of your file page.
Your API key. You can generate an API key on your 3QSDN account settings page.
Once you have these two things, you can use the following API endpoint to get the download URI:
GET
You need to replace ProjectId and FileId with your actual IDs, and add a header called X-AUTH-APIKEY with your API key as the value. You can use any tool or language that supports HTTP requests, such as Postman, curl, Python, etc.
The response of this API call will The response of this API call will be a JSON object that contains various information about your file, including the download URI. Depending on whether you have enabled Content Distribution Protection or not, the download URI will be different.
If Content Distribution Protection is enabled
If you have enabled Content Distribution Protection for your file, the download URI will be a temporary link that expires after a certain time. You can specify the expiration time in seconds by adding a query parameter called expires to the API endpoint. For example, if you want the download URI to expire after 10 minutes, you can use this API endpoint:
GET
The response will include a field called download_uri that looks something like this:
"download_uri": "
The token is a randomly generated string that is valid only for the specified expiration time. You need to use this download URI as soon as possible before it expires. If you try to use an expired download URI, you will get an error message.
If Content Distribution Protection is disabled
If you have disabled Content Distribution Protection for your file, the download URI will be a permanent link that does not expire. You do not need to add any query parameter to the API endpoint. The response will include a field called download_uri that looks something like this:
"download_uri": "
You can use this download URI anytime you want to download your file. However, keep in mind that anyone who has access to this download URI can also download your file, so be careful who you share it with.
How to use the download.sh script with CURL
Once you have the download URI, you can use a shell script called download.sh that uses CURL to download your file. This script is provided by 3QSDN on their GitHub page. It has some advantages over using CURL directly, such as:
It automatically handles the expiration time and token of the temporary download URI
It supports resume and retry of interrupted downloads
It verifies the integrity of the downloaded file using MD5 checksum
It shows the progress and speed of the download
To use this script, you need to have two things:
The requirements and parameters of the script
You need to have CURL installed on your system. You can check if you have CURL by typing curl --version in your terminal. If you do not have CURL, you can install it from here. You also need to have the script itself, which you can download from here. Save it in a folder where you want to store your downloaded file.
The script takes two parameters: the download URI and the output filename. The download URI is the one you got from the API, and the output filename is the name you want to give to your downloaded file. For example, if you want to download a file called video.mp4 from 3QSDN and save it as myvideo.mp4 in your current folder, you can use this command:
./download.sh myvideo.mp4
The example and output of the script
Here is an example of how the script works and what it outputs:
$ ./download.sh myvideo.mp4 Downloading ... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 100M 100 100M 0 0 10.5M 0 0:00:09 0:00:09 --:--:-- 11.1M Download completed. Verifying MD5 checksum ... MD5 checksum verified. File saved as File saved as myvideo.mp4
Congratulations, you have successfully downloaded your file from 3QSDN using the download.sh script with CURL.
