async function fetchCsv() {
const response = await fetch('/data/nodes.csv')
const reader = response.body.getReader()
const result = await reader.read() // raw array
const decoder = new TextDecoder('utf-8');
const csv = decoder.decode(result.value) // 获得结果是一堆奇怪的html代码,不是预期数组
const csv = decoder.decode(result) // 错误出现在该行,错误详情放下面了。
const results = Papa.parse(csv, { header: true }) // object with { data, errors, meta }
const rows = results.data // array of objects
错误详情:Uncaught TypeError: Failed to execute 'decode' on 'TextDecoder': The provided value is not of type '(ArrayBuffer or ArrayBufferView)'
直接把文件路径写parse方法里对我也不行,也是出现一堆奇怪的html代码,非预期数组
import Papa from 'papaparse';
fetchCsv = ()=>{
let data;
Papa.parse('/data/nodes.csv',{
download: true,
dynamicTyping: true,
complete: function(results){
data = results.data;
用require获取csv文件可行👍
import Papa from 'papaparse';
fetchCsv = ()=>{
var csvFilePath = require("/data/nodes.csv");
Papa.parse(csvFilePath,{
download: true,
dynamicTyping: true,
complete: function(results){
data = results.data;
