本篇内容主要讲解“uniapp小程序如何获取位置经纬度信息”,感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习“uniapp小程序如何获取位置经纬度信息”吧!
一、相关代码
判断手机定位是否授权
// 定位授权 getLocation() { let that = this; // 1、判断手机定位服务【GPS】 是否授权 uni.getSystemInfo({ success(res) { console.log("判断手机定位服务是否授权:", res); let locationEnabled = res.locationEnabled; //判断手机定位服务是否开启 let locationAuthorized = res.locationAuthorized; //判断定位服务是否允许微信授权 if (locationEnabled == false || locationAuthorized == false) { //手机定位服务(GPS)未授权 uni.showToast({ title: "请打开手机GPS", icon: "none", }); } else { //手机定位服务(GPS)已授权 // 2、判断微信小程序是否授权位置信息 // 微信小程序已授权位置信息 uni.authorize({ //授权请求窗口 scope: "scope.userLocation", //授权的类型 success: (res) => { that.fnGetlocation(); }, fail: (err) => { err = err["errMsg"]; uni .showModal({ content: "需要授权位置信息", confirmText: "确认授权", }) .then((res) => { console.log(res); if (res[1]["confirm"]) { uni.openSetting({ success: (res) => { if (res.authSetting["scope.userLocation"]) { // 授权成功 uni.showToast({ title: "授权成功", icon: "none", }); that.fnGetlocation(); } else { // 未授权 uni.showToast({ title: "授权失败,请重新授权", icon: "none", }); uni.showModal({ title: "授权", content: "获取授权" + authouName + "失败,是否前往授权设置?", success: function (result) { if (result.confirm) { uni.openSetting(); } }, fail: function () { uni.showToast({ title: "系统错误!", icon: "none", }); }, }); } }, }); } if (res[1]["cancel"]) { // 取消授权 uni.showToast({ title: "你拒绝了授权,无法获得周边信息", icon: "none", }); } }); }, complete(res) { // console.log('授权弹框', res); if (res.errMsg == "authorize:ok") { that.fnGetlocation(); } else { uni.showModal({ title: "授权", content: "获取授权" + authouName + "失败,是否前往授权设置?", success: function (result) { if (result.confirm) { uni.openSetting(); } }, fail: function () { uni.showToast({ title: "系统错误!", icon: "none", }); }, }); } }, }); } }, }); },
判断小程序是否授权位置信息 (代码在上方)
定位获取
// 定位获取 fnGetlocation() { let that = this; uni.getLocation({ type: "wgs84", //默认为 wgs84 返回 gps 坐标 geocode: "true", isHighAccuracy: "true", accuracy: "best", // 精度值为20m success: function (res) { console.log("定位获取:", res); let platform = uni.getSystemInfoSync().platform; if (platform == "ios") { //toFixed() 方法可把 Number 四舍五入为指定小数位数的数字。 that.bindList.long = res.longitude.toFixed(6); that.bindList.lat = res.latitude.toFixed(6); } else { that.bindList.long = res.longitude; that.bindList.lat = res.latitude; } that.bindList.longlat = "经度" + that.changeTwoDecimal_f(that.bindList.long) + "/" + "纬度" + that.changeTwoDecimal_f(that.bindList.lat); that.getAreaCode(res.latitude, res.longitude); }, fail(err) { if ( err.errMsg === "getLocation:fail 频繁调用会增加电量损耗,可考虑使用 wx.onLocationChange 监听地理位置变化" ) { uni.showToast({ title: "请勿频繁定位", icon: "none", }); } if (err.errMsg === "getLocation:fail auth deny") { // 未授权 uni.showToast({ title: "无法定位,请重新获取位置信息", icon: "none", }); authDenyCb && authDenyCb(); that.isLocated = false; } if ( err.errMsg === "getLocation:fail:ERROR_NOCELL&WIFI_LOCATIONSWITCHOFF" ) { uni.showModal({ content: "请开启手机定位服务", showCancel: false, }); } }, }); },
通过经纬度坐标获取区域码
// getAreaCode通过经纬度(wgs84)坐标获取区域码 getAreaCode(latitude, longitude) { this.$refs.uForm.resetFields(); var that = this; that.$u.api .getAreaCode({ latitude: latitude, longitude: longitude, }) .then((res) => { if (res.code == 100000000) { console.log("通过经纬度坐标获取区域码:", res); // console.log(res, 'areaCode'); that.bindList.areaCode = res.data.areaCode; that.bindList.specificAddress = res.data.detailLocation; that.bindList.address = res.data.areaLocation; } else { uni.showToast({ title: res.msg, icon: "none" }); } }) .catch((err) => { this.loadState = "加载失败err"; console.log("getDevList_err:", err); //-------------------- }); },
