如何在Python 2中发送HEAD HTTP请求？ [英] How do you send a HEAD HTTP request in Python 2?

问题描述

我在这里要做的是获取给定URL的标题，以便我可以确定MIME类型。我希望能够看到 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，以便我可以读取MIME类型而无需下载内容。有没有人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

编辑：这个答案有效，但是现在您应该使用下面其他答案中提到的请求库。

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 getheader（名称）获取特定标题。
