Google是否有适用于Python的官方Image API？

Question

我想使用Python脚本搜索图像并将它们从网络中拉出。有这样的官方API吗？如果没有API，最好的方法是什么？

Answer 1

谷歌官方API用于访问搜索功能，包括图像。他们使用JSON进行通信，因此可以通过Python轻松访问。他们周围有很多Python包装器，如this one。

Answer 2

我用下面的代码在Python搜索谷歌图像和图像下载到我的电脑，它使用JSON和FancyURLopener检索数据：

import os 
import sys 
import time 
from urllib import FancyURLopener 
import urllib2 
import simplejson 

# Define search term 
searchTerm = "hello world" 

# 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*4)+'&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 
     print myUrl['unescapedUrl'] 

     myopener.retrieve(myUrl['unescapedUrl'],str(count)+'.jpg') 

    # Sleep for one second to prevent IP blocking from Google 
    time.sleep(1)
