如何使用mechanize库执行HEAD请求？ [英] How can I perform a HEAD request with the mechanize library?

问题描述

我知道如何使用httplib执行HEAD请求，但我必须为此站点使用mechanize。

I know how to do a HEAD request with httplib, but I have to use mechanize for this site.

基本上，我需要做的是从标题（文件名）中获取一个值而不实际下载文件。

Essentially, what I need to do is grab a value from the header (filename) without actually downloading the file.

我有什么建议可以实现这个目标吗？

Any suggestions how I could accomplish this?

推荐答案

Mechanize本身只发送GET和POST，但你可以轻松扩展请求类发送HEAD。示例：

Mechanize itself only sends GETs and POSTs, but you can easily extend the Request class to send HEAD. Example:

import mechanize

class HeadRequest(mechanize.Request):
    def get_method(self):
        return "HEAD"

request = HeadRequest("http://www.example.com/")
response = mechanize.urlopen(request)

print response.info()
