uni.app开发小程序如何获取当前经纬度、位置信息以及如何重新发起授权定位
uni.app开发小程序如何获取当前经纬度、位置信息以及如何重新发起授权定位
- 前提 先去微信小程序后台申请 wx.getLocation接口
- 1.引入下载的高德小程序SDK
- 2.data中定义所需变量
- 3.onLoad中获取实例 并调用获取经纬度 位置方法
- 4.定义获取定位经纬度 位置信息方法
- 5.用户拒绝授权后,可重新发起授权

2.data中定义所需变量
amapPlugin: null,
key: 'xxxxx', //高德小程序key
SignAddress:'' //位置信息
3.onLoad中获取实例 并调用获取经纬度 位置方法
async onLoad(options) {
this.amapPlugin = new amap.AMapWX({
key: this.key
});
await _this.getNowPlace() //获取定位方法
},
4.定义获取定位经纬度 位置信息方法
//获取当前定位
getNowPlace() {
uni.getLocation({
type: 'gcj02',
success: function(res) {
console.log('获取定位111', res);
console.log('当前位置的经度：' + res.longitude);
console.log('当前位置的纬度：' + res.latitude);
}
});
this.amapPlugin.getRegeo({
success: (data) => {
console.log('高德地图', data)
//获取位置
this.SignAddress =data[0].name;
uni.showToast({
title: '获取位置成功',
duration: 2000,
icon: 'none'
});
uni.hideLoading();
},
fail: function(err) {
console.log('获取位置失败', err)
uni.showToast({
title: '获取位置失败',
duration: 2000,
icon: 'error'
});
}
});
},
5.用户拒绝授权后,可重新发起授权
//重新发起获取当前位置授权
rGetLocation() {
let _this = this
uni.authorize({
scope: 'scope.userLocation',
success() { //1.1 允许授权
_this.getNowPlace()
},
fail() { //1.2 拒绝授权
uni.showModal({
content: '检测到您没打开获取信息功能权限，是否去设置打开？',
confirmText: "确认",
cancelText: '取消',
success: (res) => {
if (res.confirm) {
uni.openSetting({
success: (res) => {
console.log(res);
_this.getNowPlace()
}
})
} else {
console.log('取消');
return false;
}
}
})
return false;
}
})
},
