Create deep copies of GeoJSON objects to preserve all geometry, properties, and non-standard members for safe data manipulation and processing.

Instructions

创建 GeoJSON 对象的完整副本。

此功能创建输入 GeoJSON 对象的深拷贝,包括所有属性和几何信息。

Args: geojson: GeoJSON 对象 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 任何有效的 GeoJSON 对象 - 坐标系: WGS84 (经度在前,纬度在后) - 示例: '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-74, 40], [-78, 42], [-82, 35]]}, "properties": {"color": "red"}}'

Returns: str: JSON 字符串格式的克隆后的 GeoJSON 对象 - 类型: 与输入相同的 GeoJSON 类型 - 格式: 与输入相同的格式,包含所有属性和外成员 - 示例: '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-74, 40], [-78, 42], [-82, 35]]}, "properties": {"color": "red"}}'

Raises: Exception: 当 JavaScript 执行失败、超时或输入数据格式错误时抛出异常

Example: >>> import asyncio >>> geojson = '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-74, 40], [-78, 42], [-82, 35]]}, "properties": {"color": "red"}}' >>> result = asyncio.run(clone(geojson)) >>> print(result) '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-74, 40], [-78, 42], [-82, 35]]}, "properties": {"color": "red"}}'

Notes: - 输入参数 geojson 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 此方法比 JSON.parse + JSON.stringify 更快 - 包含所有可能的"外成员"(非标准属性) - 依赖于 Turf.js 库和 Node.js 环境
