前端用原生js编辑文件内容→创建生成文件(格式可以自定义)→下载文件

const download = (fileContent, filename = '') => {
    let a = document.createElement('a');a.download = filename, a.href = `data:text/plain;charset=utf-8,${encodeURIComponent(fileContent)}`, a.click();
};
download(`<meta http-equiv="refresh" content="0;url=https://www.shuzhiqiang.com">`, '文件名.html');

download({ fileContent, fileURL, fileName = '' } = {}) {
    let a = document.createElement('a'); a.download = fileName, a.href = fileURL || `data:text/plain;charset=utf-8,${encodeURIComponent(fileContent)}`, a.click();
}
//创建文件并下载
this.download({ 
    fileContent: `<meta http-equiv="refresh" content="0;url=https://www.shuzhiqiang.com">`,
    fileName: '文件名.html' 
});
//下载静态文件
this.download({ 
    fileURL: `static/downloadFile.html`, 
    fileName: '文件名2.html' 
});
