二、运用现代JavaScript特性 随着ECMAScript标准的发展,JavaScript引入了许多新的语言特性,例如箭头函数、模板字符串、异步/等待(async/awAIt)等。这些特性可以使GIS应用的开发更加高效、简洁。 在Node.js环境下开发GIS应用时,利用这些现代JavaScript特性可以极大地提高开发效率。例如,异步/等待可以简化异步代码的编写,提高代...
egg 基于koa2封装,在方法调用上采用async ,await 形式,路由上采用内置路由 demo 'use strict'; const Controller = require('egg').Controller; class HomeController extends Controller { //注意:这里方法名index,与接下来使用的路由相关 async index() { ...
异步计算方法,使用async/await const fs=require('fs') const path=require('path'); // 使用promisify方法来promise化指定方法 const { promisify } = require('util'); stat=promisify(fs.stat) readdir=promisify(fs.readdir) // 异步 async function calcSize(dirPath,cb){ ...
问使用Node中的GDAL ogr2ogr将ogr2ogr转换为批处理格式文件EN两种解决方案： 一、将整个shapefile转为GeoJSON然后直接导入mongoDB数据库中 首先，将shapefile数据转为WGS84地理坐标，然后使用GDAL的命令行工具ogr2ogr进行格式的转换，转换命令如下： ogr2ogr -f geoJSON continents.json continents.shp ...
