前言
今天在做新需求的时候发现个很尬的问题:我们项目的小程序是直接输入账号密码进行登录的,不是平常的获得用户授权登录的模式,所以当我使用wx.getLocation一直拉不下来授权一直进fail不去success的时候我开始慌了
我以为是由于这个登录模式不同导致,然后我就开始疯狂骚扰我的小伙伴,问是不是这种登录模式会拉不到用户授权(在这里感谢我的小伙伴们没打死我,反而认真给我解惑),后来我清了下开发者工具缓存就能拉下来了(在这里求求TX的大佬们再做做开发者工具的优化吧,写原生的真的要流泪了)
如果觉得上面屁话太多可以不看哈,只要记住:
使用输入账号密码和用户授权的登录模式都是可以拉下来授权的(小声bb:其实我感觉平地都能拉授权)
使用
获得经纬度加逆解析得到详细地址
先要有个腾讯地图的key官网:https://lbs.qq.com/
贴上百度经验申请腾讯地图key的链接(比我自己写的详细得多):jingyan.baidu.com/article/656…
贴上官网API地址:developers.weixin.qq.com/miniprogram…
记得在app.json里面配置:
"permission": { "scope.userLocation": { "desc": "我们将根据您的定位进行服务分类" } },
参数什么的以官方的为准,以下为具体代码:
var QQMapWX = require('../../../utils/qqmap-wx-jssdk.js'); const { request } = require("../../../utils/util"); var qqmapsdk //onload里面写的: // 实例化腾讯地图API核心类 qqmapsdk = new QQMapWX({ key: '###MiaoWu~###'//这个去腾讯地图申请 });
// 获取用户的实时位置 getAddress() { var that = this; //1、获取当前位置坐标 wx.getLocation({ type: 'wgs84', success: function (res) { //2、根据坐标获取当前位置名称,显示在顶部:腾讯地图逆地址解析 qqmapsdk.reverseGeocoder({ location: { latitude: res.latitude, longitude: res.longitude }, success: function (addressRes) { // 显示位置 var address = addressRes.result.formatted_addresses.recommend; console.log(address); that.setData({ latitude: res.latitude, longitude: res.longitude, addressNow: address }) } }) }, fail: function () { console.log("调取失败") } }) },
画地图并获得经纬度以及详细地址
方法和上面写的相差无几,就是多了点wxml的东西
官方map地址:developers.weixin.qq.com/miniprogram…
<map id="map" longitude="{{longitude}}" latitude="{{latitude}}" scale="14" show-scale show-location style="width: 100%; height: 100vh;"> <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">确定</cover-view> </map>
业务需求不能让用户搜索以及选点,只能看自己所在位置,再加上开发者工具上暂不支持比例尺,所以这个图就当看着意思意思(还有开发者工具上定位贼不准,都给我整到区政府去了,各位在用的时候还是看自己手机调吧)
最后贴上逆解析文件qqmap-wx-jssdk.js的代码:

总感觉还有啥没写,但又想不起来了,回头记起来补吧
实话感觉自己写的这个没什么技术含量,就当给自己的一个总结,所以求各位轻喷
使用如果有问题的话就在评论区滴滴,我会的都跟你说啾咪,就这样啦~
