请看这个网站,翻页是通过ajax的,并没有刷新界面。
我做了爬虫想爬去上面的content,按照网上的教程,发送一个xmlhttprequest:
放一个data和一个header:
#-*- coding: UTF-8 -*-
import sys
import time
from HTMLParser import HTMLParser
import requests
import random
from bs4 import BeautifulSoup
reload(sys)
sys.setdefaultencoding('utf8')
def get_info(url):
info_list=[]
headers={"User-Agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.85 Safari/537.36 QQBrowser/3.9.3943.400"
'X-Requested-With': 'XMLHttpRequest'}
data={
"searchKey":"虚拟化",
"bidType":"0",
"bidWay":"0",
"region":"0",
"solrType":"0",
"frontMobanType":"1",
"pageNum":"2",#应该就是通过传输这个pageNum给服务器实现翻页
"pageCount":"30"
}
try:
content = requests.post(url,data=data,headers=headers).content#就是这里
#t = session.post(url,data,headers)
print content#无法print出内容,说是HTTP Status 405 - Request method 'POST' not supported
except Exception,e:
print e
return
get_info('http://www.zjzfcg.gov.cn/cggg?pageNum=1&pageCount=30&searchKey=%E5%AD%98%E5%82%A8&bidType=0&bidWay=0®ion=0')
请各位分析一波,是哪里有误?

Obviously, the post address is wrong, the real address is the one you selected in the screenshot.
(I can’t insert a picture into the reply, so I’ll add it here)
The browser does not display the complete URL information, you need to check the complete address yourself

The address of your post is wrong. The url should be the request http://www.zjzfcg.gov.cn/cggg. Remove the one after the question mark
