Download file safari

By Hường Hana 11:00 AM , , , , Leave a Comment

I am trying to trigger file download, and I am having issues to do this on Safari (FireFox & Chrome works as expected).
Here is my Java code: 

  @RequestMapping(method = RequestMethod.GET, produces = "text/csv")   @ResponseBody   public String getReports(       final HttpServletResponse response,       final @RequestParam String data) throws ParseException {     response.setHeader("Content-type", "text/csv; charset=utf-8");     response.setHeader("Content-Disposition","attachment; filename='view.csv'");     String csv = exportCurrentService.extractMatrix(data);     response.setContentLength(csv.length());      return csv;   }

And here is my client code: 

  downloadURI(url, name) {     const a = document.createElement('a');     a.href = url;     a.download = name;     document.body.appendChild(a);     a.click();     document.body.removeChild(a);   }

In Safari the response is printed out on the screen (loaded on the same page).

Note: that I have tried other methods suggested on SO but each has it's own problems.

In the response header I see that the Content-Disposition is set to inline instead of attachment. Why this is happening?

What did I do wrong?

Try without @ResponseBody and with produces = MediaType.APPLICATION_JSON_UTF8_VALUE

This won't compile, it just represents what you should do.

response.setContentType("application/force-download"); response.setContentLength((int)f.length());         //response.setContentLength(-1); response.setHeader("Content-Transfer-Encoding", "binary"); response.setHeader("Content-Disposition","attachment; filename=\"" + "xxx\"");//fileName); ... ... File f= new File(fileName);  InputStream in = new FileInputStream(f); BufferedInputStream bin = new BufferedInputStream(in); DataInputStream din = new DataInputStream(bin);  while(din.available() > 0){     out.print(din.readLine());     out.print("\n");     //this is from another answer I saw awhile ago while trying to do the same thing }

This is from another post that I saw when trying to do the same thing original author was Vineet Reynolds. I am new to SO so please inform me if this is bad practice.

Have you tried:

response.setHeader("Content-Disposition","attachment; filename=\"view.csv\"");

I don't think single quotes are allowed for quoting the filename
