Firefox不会将此文件作为CSV下载 [英] Firefox will not download this file as a CSV
问题描述
我试过了我能想到的一切。我改变了mime类型100次。更改标题400次。我通过堆栈查看十几次。这在Chrome中工作正常。很快，当我去在Firefox下载它认为它是一个xlsx文件或二进制文件。它甚至打开为xlsx，但它不认为它是一个csv，所以列不分离。如果我保存文件（而不是只是打开），它甚至不把扩展名。我甚至没有到IE，所以这是有点担心我。
I have tried everything I can think of. I have changed the mime type 100 times. Changed the headers 400 times. I've looked through stack over flow a dozen times. This works fine in Chrome. Soon as I go to download in Firefox it thinks it's a xlsx file, or a binary file. It even opens as an xlsx but it doesn't think it's a csv so the columns aren't seperated. If I save the file(instead of just hit open) it doesn't even put the extension on. I haven't even got to IE yet so this is kind of worrying me.
mime mapping
<mime-mapping>
<extension>csv</extension>
<mime-type>application/vnd.ms-excel</mime-type>
</mime-mapping>
我尝试过text / csv，application / csv，application / binary，application / octet-stream 。
I've tried text/csv, application/csv, application/binary, application/octet-stream.
public void doDownloadFile() {
PrintWriter out = null;
try {
String fileName = selectedPkgLine.getShortname() + ".csv";
HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
response.setHeader("Pragma", "public");
response.setHeader("Expires", "0");
response.setContentType(request.getServletContext().getMimeType(fileName));
response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
response.setHeader("Content-disposition", "attachment; filename=" + fileName + "");
response.setHeader("Content-Transfer-Encoding", "binary");
out = response.getWriter();
CSVWriter writer = new CSVWriter(out);
List<PkgLoad> pkgLoadList = pkgLoadService.findBetweenDates(selectedPkgLine, startDate, endDate);
List<String[]> stringList = new ArrayList<String[]>();
stringList.clear();
String[] header = {
"pkg_load_id",
"time_stamp",
"ounces",
"revolutions",
"wrap_spec_id",
"pkg_line_id"
};
stringList.add(header);
for (PkgLoad pkgLoad : pkgLoadList) {
String[] string = {
pkgLoad.getPkgLoadId().toString(),
pkgLoad.getTimeStamp().toString(),
pkgLoad.getOunces().toString(),
pkgLoad.getRevolutions().toString(),
pkgLoad.getWrapSpecId().getWrapSpecId().toString(),
pkgLoad.getPkgLineId().getPkgLineId().toString()
};
stringList.add(string);
}
response.setHeader("Content-length", String.valueOf(stringList.size()));
writer.writeAll(stringList);
out.flush();
} catch (IOException ex) {
Logger.getLogger(ViewLines.class.getName()).log(Level.SEVERE, null, ex);
} finally {
out.close();
}
}
感谢任何帮助。
Safari，Opera和Chrome可以正常工作。尚未尝试过IE。
Safari, Opera and Chrome work fine. Haven't tried IE.
是间距问题。我的文件名是file name.csv，这个工作在每个浏览器，除了firefox。很快，我把我的文件名称为filename.csv没有空间下载它找到我没有注意到，当它下载它只下载的名字的第一部分之前的空间。祝你好运！
Ok this entire time it was a spacing issue. My file name was "file name.csv" and this works in every browser except firefox. Soon as I put my file name to "filename.csv with no spaces it downloaded it find. I didn't notice that when it was downloading it was only downloading the first part of the name before the space. Good luck!
推荐答案
确定这是一个间距问题我的文件名是file name.csv 。很快，我把我的文件名称filename.csv没有空间下载它找到。我没有注意到，当它正在下载它只下载的空间之前的名称的第一部分。

以后请确保文件名在标题中有单引号。
In the future make sure the filename has a single quote around it in the header. This will allow Firefox to download it correctly(without stripping off anything past the space) if you need a space the file name.
