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:
