我想使用 python 下载谷歌图片搜索的所有图片。我使用的代码有时似乎有问题。我的代码是
import os
import sys
import time
from urllib import FancyURLopener
import urllib2
import simplejson
# Define search term
searchTerm = "parrot"
# Replace spaces ' ' in search term for '%20' in order to comply with request
searchTerm = searchTerm.replace(' ','%20')
# Start FancyURLopener with defined version
class MyOpener(FancyURLopener):
version = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11'
myopener = MyOpener()
# Set count to 0
count= 0
for i in range(0,10):
# Notice that the start changes for each iteration in order to request a new set of images for each loop
url = ('https://ajax.googleapis.com/ajax/services/search/images?' + 'v=1.0& q='+searchTerm+'&start='+str(i*10)+'&userip=MyIP')
print url
request = urllib2.Request(url, None, {'Referer': 'testing'})
response = urllib2.urlopen(request)
# Get results using JSON
results = simplejson.load(response)
data = results['responseData']
dataInfo = data['results']
# Iterate for each result and get unescaped url
for myUrl in dataInfo:
count = count + 1
my_url = myUrl['unescapedUrl']
myopener.retrieve(myUrl['unescapedUrl'],str(count)+'.jpg')
下载几页后出现如下错误:
Traceback(最近一次调用最后一次):
File "C:\Python27\img_google3.py", line 37, in <module>
dataInfo = data['results']
TypeError: 'NoneType' object has no attribute '__getitem__'
怎么办??????
最佳答案
我修改了我的代码。现在代码可以为给定查询下载 100 张图片,并且图片是全高分辨率的,即正在下载的原始图片。
我正在使用 urllib2 和美丽的汤下载图像
from bs4 import BeautifulSoup
import requests
import re
import urllib2
import os
import cookielib
import json
def get_soup(url,header):
return BeautifulSoup(urllib2.urlopen(urllib2.Request(url,headers=header)),'html.parser')
query = raw_input("query image")# you can change the query for the image here
image_type="ActiOn"
query= query.split()
query='+'.join(query)
url="https://www.google.co.in/search?q="+query+"&source=lnms&tbm=isch"
print url
#add the directory for your image here
DIR="Pictures"
header={'User-Agent':"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.134 Safari/537.36"
}
soup = get_soup(url,header)
ActualImages=[]# contains the link for Large original images, type of image
for a in soup.find_all("div",{"class":"rg_meta"}):
link , Type =json.loads(a.text)["ou"] ,json.loads(a.text)["ity"]
ActualImages.append((link,Type))
print "there are total" , len(ActualImages),"images"
if not os.path.exists(DIR):
os.mkdir(DIR)
DIR = os.path.join(DIR, query.split()[0])
if not os.path.exists(DIR):
os.mkdir(DIR)
###print images
for i , (img , Type) in enumerate( ActualImages):
try:
req = urllib2.Request(img, headers={'User-Agent' : header})
raw_img = urllib2.urlopen(req).read()
cntr = len([i for i in os.listdir(DIR) if image_type in i]) + 1
print cntr
if len(Type)==0:
f = open(os.path.join(DIR , image_type + "_"+ str(cntr)+".jpg"), 'wb')
else :
f = open(os.path.join(DIR , image_type + "_"+ str(cntr)+"."+Type), 'wb')
f.write(raw_img)
f.close()
except Exception as e:
print "could not load : "+img
print e
