r/Python on Reddit: PRAW user_agent (I'm a noob)

April 18, 2013 -

Hi, I'm trying to learn Python and I thought I'd mess around with praw. When creating a Reddit object, the format is r = praw.Reddit(user_agent = 'example') """this is what i saw on the praw docs"""

My question is: What is user_agent, and should I use the String 'example' when I make a Reddit object? The praw docs make it seem important: "NEVER lie about your user-agent. This includes spoofing popular browsers and spoofing other bots. We will ban liars with extreme prejudice."

So what should my user_agent be?

A user agent header is a string of text that is sent with HTTP requests to identify the program making the request (the program is called a "user agent"). Web browsers commonly send these in order to identify themselves (so the server can tell if you're using Chrome or Firefox, for example). Many APIs will want you to use a unique user agent string for your program. This is so that if your program misbehaves for some reason, they can more easily identify it, rather than have it look like a browser or just a generic default (this is why they tell you not to spoof a browser). The user agent is something that a human might read at some point in a log somewhere, so it's useful to include something like the name of your program and, in case of Reddit, your username in it. That way, if your program is doing something wrong, the admin reading the server logs can figure out how to talk to you.

The useragent should be True, unique, descriptive, contain your username on Reddit and the version number of your application. Like u/D__ explained, it's used by Reddit to identify your program. As concrete examples of useragents there is the one on Reddit's documentation : super happy flair bot v1.0 by /u/spladug as well as the one on PRAW's getting-started page >>> user_agent = ("Karma breakdown 1.0 by /u/_Daimon_ " ... "github.com/Damgaard/Reddit-Bots/")

r/redditdev on Reddit: Working on Praw bot. Curious about user agents and urllib

July 30, 2020 -

Building a praw bot. Would appreciate it if you guys could answer a few questions for me

Tutorial I'm following: https://www.pythonforengineers.com/build-a-reddit-bot-part-1/

In the praw.ini file, I had to list the user agent for the bot. I'm familiar with what a user agent is in general (an identifier for your browser and system in an http request). However, the tutorial I'm following above says,

Libraries like Python’s urllib are severely restricted by Reddit to prevent abuse. Reddit recommends you use your own special user agent, and that’s what we’ll do.

Why is urllib restricted by Reddit and why is it recommended I use a special user agent? Plus, wouldn't this be considered user agent spoofing?

Edit: What does reddit even mean by special user agent? Does it mean I have to create a unique identifier for my api client? Also, isnt there a way to make a custom user agent in urllib? Hypothetically if I were to use urllib for my bot how would reddit even know if I changed the user agent?

Don't worry about any of that urllib business. You won't need to bother since you're using PRAW. For the user agent, see the wiki . Special = unique.

April 19, 2015 - So there's no "equivalent" for a normal human user - every connection to reddit has a user agent, and the agent depends on how they're connecting.

When using my upvoting script, my account activity keeps saying praw, how do I spoof this? | BlackHatWorld

April 1, 2023 - I then discovered a method to grow my karma rapidly which has. been working very well so far. In 10 days I got up to 20,000 karma. Here's the problem. When I go to reddit dot com/account-activity, my user agent says PRAW, which I fear will be a problem when I start gaining posting to public subreddits and am seen by others.

r/redditdev on Reddit: How can I use my PRAW user agent data in a requests GET header?

December 23, 2020 -

My PRAW instance is authorised to scrape data from a quarantined sub. However, my application depends on requests' GET function to view the .json data for each post, e.g.,

req = requests.get(URL, headers={

"User-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.114 Safari/537.36"

}

...where URL is some Reddit post's URL with ".json" appended.

How do I structure the "User-agent" header to contain the user information I'm passing into my Reddit instance of PRAW so that I avoid a Forbidden 403?
