准备
1、在http://lbs.qq.com/网站申请key
2、在微信小程序后台把apis.map.qq.com添加进request合法域名
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();
}, );
setTimeout(() => {
this.getAddress(mapCtx);
}, );
},
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="" />
