回答1:res.download(path [, filename] [, fn]) http://expressjs.com/en/api.h...Transfers the file at path as an “attachment”. Typically, browsers will prompt the user for download. By default, the Content-Disposition header “filename=” parameter is path (this typically appears in the browser dialog). Override this default with the filename parameter.
When an error ocurrs or transfer is complete, the method calls the optional callback function fn. This method uses res.sendFile() to transfer the file.
res.download(’/report-12345.pdf’);res.download(’/report-12345.pdf’, ’report.pdf’);res.download(’/report-12345.pdf’, ’report.pdf’, function(err){ if (err) { // Handle error, but keep in mind the response may be partially-sent // so check res.headersSent } else { // decrement a download credit, etc. }});
