如何生成包含Geofire密钥的模拟数据？

Hey there! I’ve run into a similar snag with Mockaroo before—turns out it doesn’t have a built-in feature to generate GeoFire keys directly. But don’t stress, there are two solid workarounds to get the mock data your feature depends on:

1. Generate Lat/Lon First, Then Convert to GeoFire Keys #

This is the most straightforward approach if you don’t mind a quick post-processing step:

• In Mockaroo, create two number fields:
  • latitude: Set the range to -90 to 90 (valid global latitude values)
  • longitude: Set the range to -180 to 180 (valid global longitude values)
• Export your mock dataset (CSV, JSON, etc.) once it’s generated
• Use GeoFire’s official SDK to convert each pair of coordinates into a GeoFire key. Here’s a quick JavaScript example:

const GeoFire = require('geofire');

// Example entry from your Mockaroo data
const mockLocation = { latitude: 37.7749, longitude: -122.4194 };
const geofireKey = GeoFire.encodeGeohash(mockLocation.latitude, mockLocation.longitude);

console.log(geofireKey); // Outputs the corresponding GeoHash key

2. Use Mockaroo’s Custom Script Field to Generate Keys Directly #

If you want to skip post-processing entirely, you can embed a GeoHash encoding script directly into Mockaroo:

• Add a new field to your Mockaroo schema, set its type to Script
• Paste a complete GeoHash encoding function into the script editor (you can find open-source GeoHash implementations online that work in vanilla JS)
• Modify the script to generate random valid coordinates, then encode them into a GeoFire key. Here’s a simplified template:

// Full GeoHash encoding function (replace with a complete public implementation)
function encodeGeohash(latitude, longitude) {
  const base32Chars = '0123456789bcdefghjkmnpqrstuvwxyz';
  // Insert full GeoHash encoding logic here (plenty of free implementations exist online)
}

// Generate random valid coordinates
const randomLat = Math.random() * 180 - 90;
const randomLon = Math.random() * 360 - 180;

// Return the encoded GeoFire key
return encodeGeohash(randomLat, randomLon);

Once you save this script, Mockaroo will generate a valid GeoFire key for each entry in your dataset automatically.

Either method should get you the mock data you need to test your feature that relies on GeoFire keys.
