            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)

            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")

我没有把图像的链接作为输出，而是将“[]”作为输出。Can有人知道我的代码有什么问题。在

Answer 1

Google只向带有JavaScript的浏览器发送"imgres?imgurl"文件
但是mechanize.Browser()就像没有JavaScript的浏览器。在

关闭浏览器中的JavaScript并查看Google发送的HTML。在
