推荐答案

在任何语言中这都很容易，但是机制各不相同.使用wget和Shell:

This is easy in any language, but the mechanism varies. With wget and a shell:

wget 'http://search.twitter.com/search.json?q=hi' -O hi.json

要附加:

wget 'http://search.twitter.com/search.json?q=hi' -O - >> hi.json

使用Python:

urllib.urlretrieve('http://search.twitter.com/search.json?q=hi', 'hi.json')

要附加:

hi_web = urllib2.urlopen('http://search.twitter.com/search.json?q=hi');
with open('hi.json', 'ab') as hi_file:
  hi_file.write(hi_web.read())
