爬虫爬取百度图片、搜狗图片

通过以下代码可以爬取两大图片网站（百度和搜狗）的图片，对于人工智能、深度学习中图片数据的搜集很有帮助！

一、爬取百度图片

该代码可以爬取任意百度图片中自定义的图片：

python 复制代码

import requests
import re
import time
import os
 
 
def saveImg(imgurlList, imgOs):
    for i in imgurlList:
        try:
            response = requests.get(url=i).content
        except:
            print("error!")
        else:
            imgName = i[28: 36]
            with open(imgOs + imgName + ".jpg", "wb") as file:
                file.write(response)
            print(i + " 下载完成！!")
 
 
def get_asjson(page, gsm, word):
    url = f"https://image.baidu.com/search/acjson?tn=resultjson_com&logid=9123806616981181340&ipn=rj&ct=201326592&is=&fp=result&fr=&word={word}&queryWord={word}&cl=2&lm=-1&ie=utf-8&oe=utf-8&adpicid=&st=-1&z=&ic=&hd=&latest=&copyright=&s=&se=&tab=&width=&height=&face=0&istype=2&qc=&nc=1&expermode=&nojc=&isAsync=&pn={str(30 * int(page))}&rn=30&gsm={gsm}&{str(int(time.time() * 1000))}="
    headers = {

    }
    response = requests.get(url=url, headers=headers).text + "1111"
    gsm = re.findall('"gsm":"(.*?)",', response)[0]
    data = re.findall('"hoverURL":"(.*?)",', response)
    return gsm, data
 
 
 
 
if __name__ == "__main__":
    a = "1e"
    key_word = "阳台"  # 修改你要爬取的关键字
    img = key_word + "_img\\"
    os.mkdir(img)
    for i in range(1, 2):  #通过改变第二个数，修改要爬取的页数
        asjson1 = get_asjson(i, a, key_word)
        saveImg(asjson1[1], img)
        a = asjson1[0]
        while True:
            asjson2 = get_asjson(int(i) + 1, a, key_word)
            saveImg(asjson2[1], img)
            a = asjson2[0]
            break

二、爬取搜狗图片

该代码可以爬取任意搜狗图片中自定义的图片：

python 复制代码

from urllib.parse import quote
import requests
 
# 填入需要搜索的内容
key_word = quote('阳台')
 
# 通过定义page决定爬取多少页，每一页有48张图片
page=50
 
for page in range(1, page):
 
    startN=(page-1)*48
 
    url = 'https://pic.sogou.com/napi/pc/searchList?mode=1&start={}&xml_len=48&query={}'.format(startN,key_word)
 
    response = requests.get(url)
 
    json_data = response.json()
 
    allData = json_data['data']['items']
 
    img_urls=[]
    i = 0
    for data in allData:
        url = data['thumbUrl']
        img_urls.append(url)
        i=i+1
 
    for num in range(i):
        data=requests.get(img_urls[num],timeout=5).content
    # 此处需要修改保存路径
        with open('C:/Users/wbl/Desktop/AI/pc/L/'+'page'+str(page)+'-'+str(num)+'.jpg','wb')as file:
            file.write(data)
        print(num,'下载完成！！')
