问题描述
我在这里要做的是获取给定 URL 的标头，以便确定 MIME 类型.例如，我希望能够查看 http://somedomain/foo/ 是否会返回 HTML 文档或 JPEG 图像.因此，我需要弄清楚如何发送 HEAD 请求，以便无需下载内容即可读取 MIME 类型.有谁知道这样做的简单方法?
What I'm trying to do here is get the headers of a given URL so I can determine the MIME type. I want to be able to see if http://somedomain/foo/ will return an HTML document or a JPEG image for example. Thus, I need to figure out how to send a HEAD request so that I can read the MIME type without having to download the content. Does anyone know of an easy way of doing this?
推荐答案
edit:这个答案有效，但现在你应该只使用 requests 库，如下面的其他答案所述.
edit: This answer works, but nowadays you should just use the requests library as mentioned by other answers below.
使用 httplib.
>>> import httplib
>>> conn = httplib.HTTPConnection("www.google.com")
>>> conn.request("HEAD", "/index.html")
>>> res = conn.getresponse()
>>> print res.status, res.reason
200 OK
>>> print res.getheaders()
[('content-length', '0'), ('expires', '-1'), ('server', 'gws'), ('cache-control', 'private, max-age=0'), ('date', 'Sat, 20 Sep 2008 06:43:36 GMT'), ('content-type', 'text/html; charset=ISO-8859-1')]
还有一个 getheader(name) 来获取特定的标头.
There's also a getheader(name) to get a specific header.
