The author recounts how a tutoring mini‑program’s required reverse‑geocoding API from Tencent, Baidu, and Gaode each demanded ¥50,000 annually, explores cheaper shared or second‑hand options, and ultimately proposes using a static province‑city database to avoid the expense, noting the trade‑offs.
This article documents a rapid AI‑assisted workflow that turns a spontaneous idea into a functional, interactive Hangzhou food map by integrating Cursor with Gaode MCP services, writing HTML/JS, debugging, adding assets, and deploying the static site via GitHub Pages.
This article explains how to replace a paid map service with the free Tianditu API by implementing reverse geocoding, nearby and text search, and coordinate system conversion in Java, providing complete code examples and practical considerations for cost‑effective map integration.
This tutorial explains how to create a basic map navigation function using PHP by selecting a map API, setting up a PHP file, embedding the map container, initializing the map, and adding markers, with complete code examples for beginners.
This article explains why the shortest distance between two points on a map appears as a curve rather than a straight line, covering the concept of geodesic lines, map projection distortion, and how modern map APIs implement accurate distance rendering.
The article walks through setting up a low‑cost Tencent Cloud Ubuntu server with Apache or Nginx‑PHP, then demonstrates building four lightweight web utilities—a self‑hosted questionnaire system, a JavaScript QR‑code generator/scanner with short‑URL support, a Baidu‑map search tool, and a PHP script that parses Apple’s CFPropertyList to list Xcode dmg and docset download URLs.
