Reddit Random is a small microservice API to fetch a random Post from any requested Subreddit. Written entirely in C#, built on ASP.NET Core 3.1 with Docker support.

📦 Installation

A Docker image is available on the public docker registry which you can use as you like. The only thing you have to provide to the container is two environment variables:

USER_AGENT=<Your Useragent Name>
API_KEY=<Your defined Key>

For the User-Agent and other API rules please consult the Official Reddit Documentation

Docker pull

docker pull schufeli/reddit-random-service

Docker run

docker run -p "<Port>:80" --name reddit-random-service -e API_KEY="<API Key>" -e USER_AGENT="<Useragent>" reddit-random-service

Docker-Compose

Please have a look at the provided docker-compose.yml file.

🚀 How to use

Please note, for the Service to function properly you will need to provide a valid Reddit Access token with at least the read scope.

If you need to know how to get a Reddit Access token please consult this Guide

Important Information (please read)!!

Because the used Reddit API Endpoint doesn't send any Ratelimiting information back. There is currently no possible resource-saving way to handle the Rate limits. So you will need to do this on your own in your application. The easiest way would be to just allow a request every second or implementing some kind of delay (60 Request per minute allowed by Reddit). It will be added as soon as there is a solution or workaround.

Request a Post

To fetch a Post from the Service you will need to send an HTTP GET Request to your hosted Reddit Random Service (I will use localhost in the following examples!).

https://localhost<:Port>/reddit/<Subreddit> 

You also have to add two additional Headers to your Request use the following table as a reference.

Name Value
ApiKey Your defined Apikey (See Installation)
AccessToken Valid Reddit Api Accesstoken

Response

If your request was successful you will get a JSON object which is similar to the following example with the description of each element.

{
    "Subreddit": "<Subreddit Name>",
    "UserName": "<Name of the Post author>",
    "Spoiler": "<true or false>",
    "Title": "<Post Title>",
    "SelfText": "<Post Text>",
    "Permalink": "<Post Perma Link>",
    "PostLink": "<Link which is assigned to the Post>",
    "MediaSource": "<URL or Embed it depends on the Post>",
    "Gallery": "<Array of URL's>",
    "PostType": "<Table below>"
}

Please note that you might have to unescape the IFrame Embed as it is sent via a JSON object!

PostType's

Code Type Description
0 Image Link to the image will be the value of MediaSource
1 Video Link to the video will be the value of MediaSource
2 Embed Link or IFrame Embed will be the value of MediaSource
3 Text Will be the content of SelfText
4 Gallery The Gallery Array will contain a string Url for each image (element)

Troubleshooting

When you encounter one of the following Status Code Results with a high chance they have been sent from the Reddit API and have the following meanings.

Status Code Description
401 Accesstoken is invalid or does not exists.
403 The Requests Subreddit does not exist.
404 The Requested Subreddit does not exist or query name was too long.
