此页面通过创建逗号分隔的字符串并通过设置数据类型来强制浏览器下载csv，从而下载csv
let uri = "data:text/csv;charset=utf-8," + enpreURIComponent(content);window.open(uri, "Some CSV");
chrome上的此按钮会打开一个新标签。
您可以点击此事件，然后将内容实际下载到文件中。不知道这是否是最好的方法，但是效果很好。
const browser = await puppeteer.launch({ headless: true});browser.on('targetcreated', async (target) => { let s = target.url(); //the test opens an about:blank to start - ignore this if (s == 'about:blank') { return; } //unenpre the characters after removing the content type s = s.replace("data:text/csv;charset=utf-8,", ""); //clean up string by unencoding the %xx ... fs.writeFile("/tmp/download.csv", s, function(err) { if(err) { console.log(err); return; } console.log("The file was saved!"); }); });const page = await browser.newPage();.. open link ..... click on download link ..
