Question

如何用Python写一个http post请求

Answer 1

用这个：class urllib2.Request(url[, data][, headers][, origin_req_host][, unverifiable])

其中data就是post的内容。
从别的地方找了个例子一看就能懂。

import urllib
import urllib2
url = 'http://umbra.nascom.nasa.gov/cgi-bin/eit-catalog.cgi'
values = {'obs_year':'2011','obs_month':'March',
'obs_day':'8','start_year':'2011'
,'start_month':'March','start_day':'8'
,'start_hour':'All Hours','stop_year':'2011'
,'stop_month':'March','stop_day':'8'
,'stop_hour':'All Hours','xsize':'All'
,'ysize':'All','wave':'all'
,'filter':'all','object':'all'
,'xbin':'all','ybin':'all'
,'highc':'all'}
data = urllib.urlencode(values)
print data
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
print the_page
