微信小程序--获取用户地理位置名称(无须用户授权)

在本文 微信小程序--获取用户地理位置名称(无须用户授权) 之前需要先看看

微信小程序-获取用户session_key,openid,unionid - 后端为nodejs

代码封装是在上文添加的。

准备

效果

添加封装

  /*** 发起网络请求* @param {string} url  * @param {object} params * @return {Promise} */static request(url, params, method = "GET", type = "json") {console.log("向后端传递的参数", params);return new Promise((resolve, reject) => {let opts = {url: url,data: Object.assign({}, params),method: method,header: { 'Content-Type': type },success: resolve,fail: reject}// console.log("请求的URL", opts.url);wx.request(opts);});};/*** 获取用户中心位置经纬度* @param {ctx} name */static getCenterLocation(name) {return new Promise((resolve, reject) => name.getCenterLocation({ success: resolve, fail: reject }));}

如果已经存在,则不用添加

js

let app = getApp();
let wechat = require("../../utils/wechat");
Page({onReady(e) {let mapCtx = wx.createMapContext('myMap');setTimeout(() => {mapCtx.moveToLocation();}, 1000);setTimeout(() => {this.getAddress(mapCtx);}, 2000);},getAddress(mapCtx) {wechat.getCenterLocation(mapCtx).then(d => {console.log(d);let { latitude, longitude } = d;console.log("当前位置纬度", latitude, "当前位置经度", longitude);let url = `https://apis.map.qq.com/ws/geocoder/v1/`;let key = 'XXXXX-D6FAD-RSG4U-HBE6F-NVFNK-XXXXX';let params = {location: latitude + "," + longitude,key}return wechat.request(url, params);}).then(d => {console.log(d);console.log("当前地址", d.data.result.address);}).catch(e => {console.log(e);})}})

html

<map id="myMap" show-location="true" scale="16" />

css
