《冷暖自知》天气小程序
学无止境,以玩儿玩儿的心态去学习!
前一天晚上写的,写的不太好,第二天马上修改了,如有差错,请多指教。
花半天时间完成简单的小程序应用。适合小程序初学者。
步骤:
- 申请小程序帐号: 小程序注册入口, 具体操作按照官网步骤执行,相信你会看的很明白的(-
- 安装微信开发者工具,打开工具填写信息:①项目目录为自己要开发小程序的位置②AppId在微信管理后台的设置-开发设置中③项目名称自己起,填写完成点击完成;
- 看到默认的初始小程序Hello Horld是不是很兴奋,以上步骤不是我们今天研究的重点,下面进行我们的关键:
- 在index.wxml中写我们的结构,index.wxss中写css样式,在index.js中写我们的逻辑内容。前提是要有css3和javascript的基础哦!!!
- 在index.js中定义两个方法:getLocation()获取用户的地理位置,getWeather()获取天气的方法;
- 和风天气提供免费天气接口(无偿打广告,哈哈~~),免费版只能获取3天的天气情况,开发文档
废话不多说,直接上代码~~~

//index.js
//获取应用实例
const app = getApp()

var latitude = res.latitude
var longitude = res.longitude
that.getWeatherInfo(latitude, longitude);
}
})
},
getWeatherInfo: function (latitude, longitude){
var _this = this;
var key = ‘‘;//你自己的key
//需要在微信公众号的设置-开发设置中配置服务器域名
var url = ‘https://free-api.heweather.com/s6/weather?key=‘+key+‘&location=‘ + longitude + ‘,‘ + latitude;
wx.request({
url: url,
data: {},
method: ‘GET‘,
success: function (res) {
var daily_forecast_today = res.data.HeWeather6[0].daily_forecast[0];//今天预报
var daily_forecast_tomorrow = res.data.HeWeather6[0].daily_forecast[1];//明天天预报
var daily_forecast_afterTomor = res.data.HeWeather6[0].daily_forecast[2];//后天预报
var basic = res.data.HeWeather6[0].basic;
var update = res.data.HeWeather6[0].update.loc;//更新时间
_this.setData({
update:update,
basic:basic,
today: daily_forecast_today,
tomorrow:daily_forecast_tomorrow,
afterTomor: daily_forecast_afterTomor,
todyIcon: ‘../../imgs/weather/‘ + daily_forecast_today.cond_code_d+‘.png‘, //在和风天气中下载天气的icon图标,根据cond_code_d显示相应的图标
tomorrowIcon: ‘../../imgs/weather/‘ + daily_forecast_tomorrow.cond_code_d+‘.png‘,

效果
大功搞成,这样就有了自己的天气预报了,天气变冷,大家注意身体哦,身体是革命的本钱!!!
