Question

#!/usr/bin/env python


import urllib
import mechanize
from bs4 import BeautifulSoup
from urlparse import urlparse

def getPic(search):
    search = search.replace(" ","%20")
    try:
            browser = mechanize.Browser()
            browser.set_handle_robots(False)
            browser.addheaders = [('User-Agent','Mozilla')]

            htmltext = browser.open("https://www.google.com/search?site=&tbm=isch&source=hp&biw=1855&bih=990&q=" + search + "&oq=" +search)
            img_url = []
            formatted_images = []
            soup = BeautifulSoup(htmltext)
            results = soup.findAll("a")
            for r in results:
                    try:
                            if "imgres?imgurl" in r['href']:
                                    img_url.append(r['href'])
                    except:
                            a=0
            for im in img_url:
                    refer_url = urlparse(str(img_url[0]))
                    return refer_url.query.split("&")[0].replace("imgurl=","")
            return  formatted_images


    except:
            print "error"
print getPic("occupy wall street")

不是将图像的链接作为输出而是获得＆＃34; []＆＃34;作为一个输出。可以找出我的代码的问题是什么。

Answer 1

Google仅向使用JavaScript的浏览器发送"imgres?imgurl" 但mechanize.Browser()就像没有JavaScript的浏览器。

在浏览器中关闭JavaScript并查看Google发送的HTML。

从python搜索谷歌图片
