React Next项目中导入Echart世界航线图并配置中文

公司业务要求做世界航线图，跑了三个ai未果，主要是引入world.json失败，echart包中并不携带该文件，源码的world.json文件页面404找不到。需要自己寻找。这是整个问题卡壳的关键点，特此贴出资源网址。

一、安装

二、下载world.json

三、创建地图组件WorldMap.js

四、引入地图组件到页面上

五、配置中文

六、中文转换函数

一、安装

npm install echarts

二、下载world.json

world.json在最下面，点开直接粘贴到自己项目中引入

Index of /examples/data/asset/geo

三、创建地图组件WorldMap.js

import React, { useRef, useEffect } from "react";
import * as echarts from "echarts";

const geoCoordMap = {
    "New York": [-74.0060, 40.7128],
    "London": [-0.1278, 51.5074],
    "Tokyo": [139.6917, 35.6895],
    "Beijing": [116.4074, 39.9092],
};

const SHData = [
    [{ name: "Beijing", value: 105 }, { name: "New York", value: 105 }],
    [{ name: "Beijing", value: 105 }, { name: "London", value: 105 }],
    [{ name: "Beijing", value: 105 }, { name: "Tokyo", value: 105 }],
];

const convertData = (data) => {
    const res = [];
    for (let i = 0; i < data.length; i++) {
        const dataItem = data[i];
        const fromCoord = geoCoordMap[dataItem[0].name];
        const toCoord = geoCoordMap[dataItem[1].name];
        if (fromCoord && toCoord) {
            res.push({
                fromName: dataItem[0].name,
                toName: dataItem[1].name,
                coords: [fromCoord, toCoord],
            });
        }
    }
    return res;
};

const WorldMap = () => {
    const chartRef = useRef(null);

    useEffect(() => {
        // 动态加载世界地图数据
        fetch("/world.json") // 确保文件路径正确，这里假设 world.json 放在 public 文件夹下
            .then((res) => res.json())
            .then((mapData) => {
                echarts.registerMap("world", mapData); // 注册地图数据

                const myChart = echarts.init(chartRef.current);

                const seriesData = [
                    {

                        data: convertData(SHData),
                    },
                    {
                        type: "effectScatter",
                        coordinateSystem: "geo",
                        zlevel: 2,
                        rippleEffect: {
                            brushType: "stroke",
                        },
                        label: {
                            show: true,
                            position: "right",
                            formatter: "{b}",
                        },
                        symbolSize: (val) => val[2] / 8,
                        itemStyle: {
                            color: "#46bee9",
                        },
                        data: SHData.map((dataItem) => ({
                            name: dataItem[1].name,
                            value: geoCoordMap[dataItem[1].name].concat([dataItem[1].value]),
                        })),
                    },
                ];

                myChart.setOption({
                    geo: {
                        map: "world",
                        roam: true,
                        itemStyle: {
                            areaColor: "#404a59",
                            borderColor: "#61727a",
                        },
                        emphasis: {
                            itemStyle: {
                                areaColor: "#7acfd6",
                            },
                        },
                    },
                    series: seriesData,
                });
            })
            .catch((error) => {
                console.error("Failed to load world map data:", error);
            });
    }, []);

    return <div ref={chartRef} style={{ width: "100%", height: "600px" }} />;
};

export default WorldMap;

四、引入地图组件到页面上

import React from "react";
import styles from "../styles/AfterSalesPage.module.css";
import WorldMap from "../components/WorldMap"; // 确保使用默认导入

const AfterSales = () => {
	return (
		<div className={styles.newsContainer}>
			<WorldMap />
		</div>
	);
};

export default AfterSales;

成果展示：

六、中文转换函数

在WorldMap.js这个地图组件中，引入mapZHName.js，并添加转化函数，和航线地名的映射表。

完整代码如下：

import React, { useRef, useEffect } from 'react';
import * as echarts from 'echarts';
import { mapZHName } from '../public/mapZHName'; // 确保正确导入映射文件

const geoCoordMap = {
  中国: [104.195397, 35.86166],
  纽约: [-74.006, 40.7128],
  伦敦: [-0.1278, 51.5074],
  东京: [139.6917, 35.6895],
};

//配置航线
const SHData = [
  [
    { name: '中国', value: 105 },
    { name: '中国', value: 105 },
  ],
  [
    { name: '中国', value: 105 },
    { name: '伦敦', value: 105 },
  ],
  [
    { name: '中国', value: 105 },
    { name: '东京', value: 105 },
  ],
];

// 将 SHData 中的城市名称和对应的值转换为 ECharts 地图所需的连线数据格式
const convertData = (data) => {
  const res = [];
  for (let i = 0; i < data.length; i++) {
    const dataItem = data[i];
    const fromCoord = geoCoordMap[dataItem[0].name];
    const toCoord = geoCoordMap[dataItem[1].name];
    if (fromCoord && toCoord) {
      res.push({
        fromName: dataItem[0].name,
        toName: dataItem[1].name,
        coords: [fromCoord, toCoord],
      });
    }
  }
  return res;
};

const WorldMap = () => {
  const chartRef = useRef(null);

  // 中文转换函数定义在组件内部
  const formatWorldMapToZH = (data) => {
    if (data.features) {
      data.features = data.features.map((item) => {
        if (mapZHName[item.properties.name]) {
          item.properties.name = mapZHName[item.properties.name];
        }
        return item;
      });
    }
    return data;
  };

  useEffect(() => {
    // 动态加载世界地图数据
    fetch('/world.json') // 确保文件路径正确，这里假设 world.json 放在 public 文件夹下
      .then((res) => res.json())
      .then((mapData) => {
        // 调用转换函数将地图数据中的英文地名转换为中文
        const formattedMapData = formatWorldMapToZH(mapData);

        echarts.registerMap('world', formattedMapData); // 注册地图数据

        const myChart = echarts.init(chartRef.current);

        const seriesData = [
          {
            type: 'lines',
            zlevel: 1,
            effect: {
              show: true,
              period: 6,
              trailLength: 0.7,
              color: '#fff',
              symbolSize: 3,
            },
            lineStyle: {
              color: '#46bee9',
              width: 0,
              curveness: 0.2,
            },
            data: convertData(SHData),
          },
          {
            type: 'lines',
            zlevel: 2,
            symbol: ['none', 'arrow'],
            symbolSize: 10,
            effect: {
              show: true,
