vue实现世界疫情地图(点击进入子地图)
vue实现世界疫情地图，点击可以进入子地图
点击进入子地图目前只实现了中国模块 数据来源，腾讯实时疫情，中国疫情网 原本只想做中国模块，后来想了想，做个世界的吧 使用axios和echarts，elementui的加载模块还有按钮，本地代理，脚手架版本4.1.1 本次不封装，刚写完还没有优化，函数名和数据名也是随便起的，大佬勿喷 npm安装即 github地址https://github.com/dmhsq/echartsMap-epidemic 可看完本文还有一个疫情大屏数据等着你哦 vue疫情大屏数据展示+数据导出+地图图片下载
效果展示
下载的照片如下
寻找数据源
找了几家后发现中国疫情网的国内疫情数据更新的快，腾讯海外疫情也不错
中国疫情网的数据:
这个是全国数据
这个是按照日期
设置代理
用axios请求这些数据如果出现跨域问题，就设置本地代理，在根目录下创建vue.config.js文件
module.exports = {
devServer: {
proxy: {
"/api": {
target: "https://www.ncovchina.com/data",
changeOrigin: true,
pathRewrite: {
"^/api": ""
}
},
"/aki": {
target: "http://api.fanyi.baidu.com/api/trans/vip",
changeOrigin: true,
pathRewrite: {
"^/aki": ""
}
}
},
host: "0.0.0.0",
port: 8083,
clientLogLevel: "info"
}
};api是中国疫情网数据
aki是百度翻译接口，但是本次不用，因为百度翻译标准版返回的不准，用的爱翻译的谷歌翻译
发送请求提取数据
提取数据
axios.post(/api/getDisease.html)
获得数据
国内疫情数据获取并提取
this.isLoading = true;
axios.post(`/api/getDisease.html`).then(res => {
let data = JSON.parse(res.data.data);
console.log(data);
let dss = data.areaTree[0].children;
this.datas = dss;
this.chinaTotal = data.chinaTotal.confirm;
this.chinaAdd = data.chinaAdd.confirm;
this.chinaNow = data.chinaTotal.nowConfirm;
this.lastTime = data.lastUpdateTime;
this.isLoading = false;
});分别提取了新增，总确诊，现存确诊
在绘制中国疫情地图时需要
axios
.post(
“https://api.inews.qq.com/newsqa/v1/automation/foreign/country/ranklist”
)
获取海外疫情这里获取了185个国家的数据
海外疫情数据获取并提取
this.isLoading = true;
axios
.post(
"https://api.inews.qq.com/newsqa/v1/automation/foreign/country/ranklist"
)
.then(res => {
let data = res.data.data;
let names = [];
data.forEach(item => {
names.push(item.name);
});
this.worldData = data;
this.test(names).then(res => {
console.log(res.data.dst);
let ss = res.data.dst;
console.log(ss);
let namess = ('"' + ss.replace(/, /g, '","') + '"').split(",");
this.worldNames = namess;
this.setEc(this.check);
this.isLoading = false;
});
});test函数封装了爱翻译的谷歌翻译,setEc是绘制地图函数
test(content) {
return axios.post(
"http://api.aifanyi.net/google.php",
`content=${content}&from=zh-CN&fromtxt=中文&to=英文&totxt=英语`
);
},为什么要这样提取数据，因为echarts地图数据是英文匹配，直接翻译即可
namess为提取翻译后的国家数组赋值给worldName
worldData为海外疫情数据
names.push是提取国家名以便于翻译
踩坑
百度翻译，腾讯翻译，有道翻译会导致翻译不准数据减少，给185个国家名字，返回了174或者多点
Push会改变原格式，所有我们先push字符串再把字符串赋值给地图数据，见下面
处理数据并绘图
国内疫情地图数据处理绘制
let min = 0;
let max = 100;
let title = " 地图";//地图标题(总，现存，新增)
let data = [];//疫情数据
let names = [];//提取省级名字
let values = [];//提取城市疫情数据
this.check = check;//获取选择(总，现存，新增)
if (check === 0) {
title = "国内现存确诊地图";
this.datas.forEach((item, index) => {
names.push(item.name);
values.push(item.total.confirm - item.total.dead - item.total.heal);
data.push({ name: names[index], value: values[index] });
});

max = 100;
}
if (check === 1) {

this.datas.forEach((item, index) => {

});
min = 0;

}
echarts.registerMap("china", china);
let myChart = echarts.init(this.$refs.chart);
myChart.clear();

]
};
myChart.setOption(option);//绘图
this.isChina = true;//控制地图选择是否显示
myChart.on("click", function(params) {
console.log(params);
});解释
check控制选择地图类型(总，新增，现存)
min和max 还有color数组
对应最大最小和颜色梯度
myChart.on(“click”, function(params) {
console.log(params);
});

可以优化重复的比如check选择那一块，绘制也可以优化，优化的地方还有很多，这里只讲实现
大家好，我是代码哈士奇，是一名软件学院网络工程的学生，因为我是“狗”，狗走千里吃肉。想把大学期间学的东西和大家分享，和大家一起进步。但由于水平有限，博客中难免会有一些错误出现，有纰漏之处恳请各位大佬不吝赐教！暂时只在csdn这一个平台进行更新，博客主页：https://blog.csdn.net/qq_42027681。
