我有一些大尺寸的PDF目录在我的网站上，我需要链接这些下载。当我在谷歌上搜索时，我发现下面有这样一件事。它应该打开“另存为…”弹出链接点击…
<head>
<meta name="content-disposition" content="inline; filename=filename.pdf">
...
但它不工作:/当我链接到一个文件如下，它只是链接到文件，并试图打开文件。
<a href="filename.pdf" title="Filie Name">File name</a>
更新(根据以下答案):
据我所知，没有100%可靠的跨浏览器解决方案。也许最好的方法是使用下面列出的web服务之一，并提供下载链接…

只要把下面的代码放在你的。htaccess文件中:
AddType application/octet-stream .csv
AddType application/octet-stream .xls
AddType application/octet-stream .doc
AddType application/octet-stream .avi
AddType application/octet-stream .mpg
AddType application/octet-stream .mov
AddType application/octet-stream .pdf
或者你也可以通过JavaScript来实现
element.setAttribute( 'download', whatever_string_you_want);
其他回答
从答案到强制浏览器保存文件为单击链接后:
<a href="path/to/file" download>Click here to download</a>
在HTML代码中的文件名之后，我添加?forcedownload=1
对我来说，这是触发对话框进行保存或下载的最简单方法。
服务器端解决方案更具兼容性，直到“download”属性在所有浏览器中实现。
一个Python示例可以是文件存储的自定义HTTP请求处理程序。指向文件存储的链接是这样生成的:
http://www.myfilestore.com/filestore/13/130787e71/download_as/desiredName.pdf
代码如下:
class HTTPFilestoreHandler(SimpleHTTPRequestHandler):
def __init__(self, fs_path, *args):
self.fs_path = fs_path # Filestore path
SimpleHTTPRequestHandler.__init__(self, *args)
def send_head(self):
# Overwrite SimpleHTTPRequestHandler.send_head to force download name
path = self.path
get_index = (path == '/')
self.log_message("path: %s" % path)
if '/download_as/' in path:
p_parts = path.split('/download_as/')
assert len(p_parts) == 2, 'Bad download link:' + path
path, download_as = p_parts
path = self.translate_path(path )
f = None
if os.path.isdir(path):
if not self.path.endswith('/'):
# Redirect browser - doing basically what Apache does
self.send_response(301)
self.send_header("Location", self.path + "/")
self.end_headers()
return None
else:
return self.list_directory(path)
ctype = self.guess_type(path)
try:
f = open(path, 'rb')
except IOError:
self.send_error(404, "File not found")
return None
self.send_response(200)
self.send_header("Content-type", ctype)
fs = os.fstat(f.fileno())
self.send_header("Expires", '0')
self.send_header("Last-Modified", self.date_time_string(fs.st_mtime))
self.send_header("Cache-Control", 'must-revalidate, post-check=0, pre-check=0')
self.send_header("Content-Transfer-Encoding", 'binary')
if download_as:
self.send_header("Content-Disposition", 'attachment; filename="%s"' % download_as)
self.send_header("Content-Length", str(fs[6]))
self.send_header("Connection", 'close')
self.end_headers()
return f
class HTTPFilestoreServer:
def __init__(self, fs_path, server_address):
def handler(*args):
newHandler = HTTPFilestoreHandler(fs_path, *args)
newHandler.protocol_version = "HTTP/1.0"
self.server = BaseHTTPServer.HTTPServer(server_address, handler)
def serve_forever(self, *args):
self.server.serve_forever(*args)
def start_server(fs_path, ip_address, port):
server_address = (ip_address, port)
httpd = HTTPFilestoreServer(fs_path, server_address)
sa = httpd.server.socket.getsockname()
print "Serving HTTP on", sa[0], "port", sa[1], "..."
httpd.serve_forever()
我刚刚用了这个，但我不知道它是否适用于所有浏览器。
它适用于Firefox:
<a href="myfile.pdf" download>Click to Download</a>
我遇到了同样的问题，找到了一个迄今为止非常有效的解决方案。你把下面的代码放在你的。htaccess文件中:
<FilesMatch "\.(?i:pdf)$">
ForceType application/octet-stream
Header set Content-Disposition attachment
</FilesMatch>
它来自于强制文件下载而不是显示在浏览器中。
