如何通过Minecraft API获取所有Minecraft用户的用户名/UUID？
Great question—this is a common pain point for anyone trying to build a tool like NameMC, since Mojang doesn’t make accessing full user data straightforward at all. Let’s break this down clearly:
The Hard Truth About Official APIs
First, let’s cut to the chase: Mojang does NOT provide any official API endpoint that lets you fetch a complete list of every Minecraft user’s username or UUID. The endpoint you referenced (https://api.mojang.com/users/profiles/minecraft/) only works for looking up individual usernames, or small comma-separated batches (with strict rate limits and caps)—it will never return all users.
How NameMC Pulls It Off
NameMC doesn’t rely on a single Mojang API dump for its full index. Instead, it’s built up over years using a mix of strategies:
- Historical Snapshots: They likely collected data from older Mojang endpoints that once had broader access (those endpoints are long retired now).
- Passive User Submission: When people search for names, link accounts, or use NameMC’s tools, the platform adds that user’s data to its database.
- Curated Third-Party Data: They may use aggregated datasets from trusted community sources that have been building user lists for years (these are rarely free or publicly available).
Realistic Options for Your Project
If you’re set on building a similar tool, here are the most feasible paths forward:
- Start Small and Grow Your Own Index
Use the official single-user lookup endpoint (GET https://api.mojang.com/users/profiles/minecraft/{username}) to fetch data on demand when users search your platform. Store each user’s data in your database, and over time, your index will grow organically. It won’t be as comprehensive as NameMC’s overnight, but it’s the most compliant way to build up your dataset. - Use Community-Curated Datasets
Some community projects have compiled partial snapshots of Minecraft usernames/UUIDs from public sources. Just be cautious here: these are never 100% complete, and you’ll need to verify that the dataset is legal to use (avoid anything that violates Mojang’s terms or user privacy). - Ethically Scrape Public Server/Skin Data
Many Minecraft servers publicly list players who’ve joined, and skin hosting services have public skin data. You can scrape this data (with strict rate limits and respect for the platform’s terms of service) to add to your index. Just never scrape Mojang’s own sites directly—this violates their terms.
Critical Compliance Reminders
- Stick to Mojang’s API Rules: Mojang strictly prohibits bulk scraping or excessive API requests. Keep your requests within their rate limits (600 requests per 10 minutes per IP) and only fetch data that’s publicly available.
- Respect User Privacy: Never store or share sensitive user data beyond what’s exposed via the official API. Minecraft users have privacy rights—don’t overstep.
