Fetch 读取本地文件出错

在网页上用js读取本地文件 （文件和html文件一个目录）：

const res = fetch('Test.csv');

结果出错：

Access to fetch at 'file:///D:/workspace/Stocks/Stock-Chart/TradingviewChartCSVFile/data.csv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https.

这个怎么处理？

谢谢

fetch 不能读取本地文件，参考 Can't fetch local file
