uniapp小程序使用高德地圖api實(shí)現(xiàn)路線規(guī)劃的示例代碼
路線規(guī)劃
簡(jiǎn)介
路線規(guī)劃常用于出行路線的提前預(yù)覽,我們提供4種類(lèi)型的路線規(guī)劃,分別為:駕車(chē)、步行、公交和騎行,滿足各種的出行場(chǎng)景。
高德開(kāi)放平臺(tái)
本例是駕車(chē)路線規(guī)劃功能和位置選擇地圖api:chooseLocation
示例:
1、在頁(yè)面的 js 文件中,實(shí)例化 AMapWX 對(duì)象,請(qǐng)求進(jìn)行駕車(chē)路線規(guī)劃。
首先,引入 amap-wx.js 文件(amap-wx.js 從相關(guān)下載頁(yè)面下載的 zip 文件解壓后得到)。
import amapFile from "@/libs/amap-wx.js";
然后在 onLoad 實(shí)例化 AMapWX 對(duì)象
onLoad() { this.myAmapFunT = new amapFile.AMapWX({ key: 你申請(qǐng)的key }) },
最后生成請(qǐng)求進(jìn)行駕車(chē)路線規(guī)劃數(shù)據(jù)
