微信小程序 通过获取地理位置查看天气

 

1.在app.json中写入

"permission": {
    "scope.userLocation": {
      "desc": "你的位置信息将用于天气预报定位"
    }
  }

2.申请和风天气APIKEY 和风天气开发平台 ~ 高效强大的天气API，天气SDK和天气插件

3.在js文件中设置变量

 const APIKEY = "APIKEY"; //申请到的和风天气key

4.获取天气代码 

  //获取天气
  getWeather() {
    var that = this
    wx.getLocation({
      type: 'gcj02',
      success(res) {
        that.setData({
          location: res.longitude + "," + res.latitude
        })
        that.getCityByLoaction()
        that.weather()
      }
    })
  }

5.根据坐标获取城市 

 getCityByLoaction() {
    var that = this
    wx.request({
      url: 'https://geoapi.qweather.com/v2/city/lookupkey=' + APIKEY + "&location=" + that.data.location,
      success(result) {
        var res = result.data
        if (res.code == "200") {
          var data = res.location[0]
          that.setData({
            City: data.adm2,
            Province: data.adm1
          })
        } else {
          wx.showToast({
            title: '获取城市信息失败',
            icon: 'none'
          })
        }
      }
    })
  }

6.获取天气情况 

 weather() {
    var that = this
    wx.showLoading({
      title: '加载中',
    })
    wx.request({
      url: 'https://devapi.qweather.com/v7/weather/nowkey=' + APIKEY + "&location=" + that.data.location,
      success(result) {
        var res = result.data
        that.setData({
          temp: res.now.temp,
          text: res.now.text,
          icon: res.now.icon
        })
      }
    })
    wx.hideLoading()
  }

 结束啦。
