我很想让这个程序在速度上提高很多。它在 10 分钟内读取 +- 12000 页。我想知道是否有什么对速度有很大帮助的东西?我希望你们知道一些提示。我应该阅读 +- 数百万页......所以这会花费太长时间:(这是我的代码:
from eventlet.green import urllib2
import httplib
import time
import eventlet
# Create the URLS in groups of 400 (+- max for eventlet)
def web_CreateURLS():
print str(str(time.asctime( time.localtime(time.time()) )).split(" ")[3])
for var_indexURLS in xrange(0, 2000000, 400):
var_URLS = []
for var_indexCRAWL in xrange(var_indexURLS, var_indexURLS+400):
var_URLS.append("http://www.nu.nl")
web_ScanURLS(var_URLS)
# Return the HTML Source per URL
def web_ReturnHTML(url):
try:
return [urllib2.urlopen(url[0]).read(), url[1]]
except urllib2.URLError:
time.sleep(10)
print "UrlError"
web_ReturnHTML(url)
# Analyse the HTML Source
def web_ScanURLS(var_URLS):
pool = eventlet.GreenPool()
try:
for var_HTML in pool.imap(web_ReturnHTML, var_URLS):
# do something etc..
except TypeError: pass
web_CreateURLS()
