這篇文章將為大家詳細講解有關微信小程序內地圖怎么用,小編覺得挺實用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
前言
在做新需求的時候發現個很尬的問題:我們項目的小程序是直接輸入賬號密碼進行登錄的,不是平常的獲得用戶授權登錄的模式,所以當我使用wx.getLocation一直拉不下來授權一直進fail不去success的時候我開始慌了
我以為是由于這個登錄模式不同導致,然后我就開始瘋狂騷擾我的小伙伴,問是不是這種登錄模式會拉不到用戶授權(在這里感謝我的小伙伴們沒打死我,反而認真給我解惑),后來我清了下開發者工具緩存就能拉下來了(在這里求求TX的大佬們再做做開發者工具的優化吧,寫原生的真的要流淚了)
如果覺得上面屁話太多可以不看哈,只要記?。?nbsp;
使用輸入賬號密碼和用戶授權的登錄模式都是可以拉下來授權的(小聲bb:其實我感覺平地都能拉授權)
使用
獲得經緯度加逆解析得到詳細地址
先要有個騰訊地圖的key官網:https://lbs.qq.com/
記得在app.json里面配置:
"permission": {
"scope.userLocation": { "desc": "我們將根據您的定位進行服務分類" } },參數什么的以官方的為準,以下為具體代碼:
var QQMapWX = require('../../../utils/qqmap-wx-jssdk.js');
const { request } = require("../../../utils/util");
var qqmapsdk
//onload里面寫的:
// 實例化騰訊地圖API核心類
qqmapsdk = new QQMapWX({
key: '###MiaoWu~###'//這個去騰訊地圖申請
}); // 獲取用戶的實時位置 getAddress() {
var that = this;
//1、獲取當前位置坐標
wx.getLocation({
type: 'wgs84',
success: function (res) {
//2、根據坐標獲取當前位置名稱,顯示在頂部:騰訊地圖逆地址解析
qqmapsdk.reverseGeocoder({
location: {
latitude: res.latitude,
longitude: res.longitude
},
success: function (addressRes) {
// 顯示位置
var address = addressRes.result.formatted_addresses.recommend;
console.log(address);
that.setData({
latitude: res.latitude,
longitude: res.longitude,
addressNow: address
})
}
})
},
fail: function () {
console.log("調取失敗")
}
})
},畫地圖并獲得經緯度以及詳細地址
方法和上面寫的相差無幾,就是多了點wxml的東西
官方map地址:developers.weixin.qq.com/miniprogram…
<map id="map" longitude="{{longitude}}" latitude="{{latitude}}"
scale="14" show-scale show-location >
<cover-view class="dosomething fr">
<cover-image class="img" src="/assets/icon/refresh.png" bindtap="toRefresh"></cover-image>
<cover-image class="img" src="/assets/icon/goSelf.png" bindtap="toRefresh"></cover-image>
</cover-view>
<cover-view class="sureLocation" bindtap="sureLocation">確定</cover-view>
</map>業務需求不能讓用戶搜索以及選點,只能看自己所在位置,再加上開發者工具上暫不支持比例尺,所以這個圖就當看著意思意思(還有開發者工具上定位賊不準,都給我整到區政府去了,各位在用的時候還是看自己手機調吧)

最后貼上逆解析文件qqmap-wx-jssdk.js的代碼:
