Cherrypy 下载serve_file

Question

I am attempting to create a zip file and the allow it to be downloaded from the webpage. I am able to get it to serve the file but instead of downloading in the browser, it makes the call and serves it as the body of the response. I just want to download the file.

def download(self, **kwargs):
        filename = kwargs["filename"]
        path = os.path.join(os.getcwd(), filename)
        return cherrypy.lib.static.serve_file(path, "application/x-download", "attachment", os.path.basename(path))
download.exposed = True

When i use chrome's inspect tools on the response from /download i can see that the content-type and disposition headers are set as expected, and can see the zip content in the response section. However, I just want to download the file. I had this working at one point but now can't seem to get it going again.

I have a CherryPy application where I do something similar and it works. Here is what the code I have looks like:

    def getzip(self, dirpath=None):
        zipfile = os.path.join(ziplink, 'hostmaps/%s' % dirpath)
        return static.serve_file(zipfile, 'application/x-download', 'attachment', os.path.basename(zipfile))

Using jinja2 template, I have a link to download the zip from the HTML like this:

<p><a href="getzip?dirpath={{ zipfile }}">Download zip archive</a></p>

Hope this helps!
