python搜索图像谷歌图像

Question

我正在用python搜索谷歌图像搜索非常艰难.我只需要使用标准的python库(所以urllib,urllib2,json,..)

有人可以帮忙吗？假设图像是jpeg.jpg并且在我正在运行python的同一文件夹中.

我尝试过一百种不同的代码版本,使用标题,用户代理,base64编码,不同的网址(images.google.com,http://images.google.com/searchbyimage？hl = zh-CN&biw = 1060&bih = 766&gbv = 2&site = search&image_url = {{URL to your image}}&sa = X&ei = H6RaTtb5JcTeiALlmPi2CQ&ved = 0CDsQ9Q8等....)

没有任何作用,它总是一个错误,404,401或破管:(

请给我看一些python脚本,它会用我自己的图像搜索谷歌图像作为搜索数据('jpeg.jpg'存储在我的计算机/设备上)

谢谢你能解决这个问题的人,

戴夫:)

Answer 1

我在Python中使用以下代码搜索Google图像并将图像下载到我的计算机：

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)
