安装node.js,同时安装好依赖：
npm install request --save // http请求库
npm install cheerio --save // 分析html工具
npm install express --save // nodejs web框架获取墨迹天气
地址示例：
东莞 tianqi.moji.com/weather/chi…
广州 tianqi.moji.com/weather/chi…
深圳 tianqi.moji.com/weather/chi…
可打开墨迹天气网站找到女朋友对应城市修改url地址拼音即可。

const request = require("request")
const cheerio = require("cheerio")
const weatherURL = 'https://tianqi.moji.com/weather/china/Guangdong/dongguan'// 获取墨迹天气提示信息
function getWeatherTips(url) {
return new Promise((resolve,reject)=>{
request(weatherURL,(error,res,body)=>{
if (!error) {
let html = res.body || "";
let $ =cheerio.load(html)
let temp = $('.wea_weather em').text().trim()+'℃'
let desc = $('.wea_weather b').text().trim()
let water = $('.wea_about span').text().trim()
let win = $('.wea_about em').text().trim()
let tips = $('.wea_tips em').text().trim()
let words=`今日${city}天气n${desc}n温度：${temp}n湿度：${water}n风力：${win}n${tips}`
resolve(words)
} else {
reject(error)
}
})
})
}
