一、生成一個保存圖片的檔案夾

這里是把檔案夾創建在.py檔案的同級目錄了可以根據自己設定

path = os.getcwd()     #獲取當前檔案所在路徑
path_name = path + '/' + '素材公社'
if not os.path.exists(path_name):
      os.mkdir(path_name)

二、獲取圖片分類選項和url 生成字典

這里要下載的分類選項不包括風景圖片人物圖片等大類

觀察鏈接末尾在推導式中用if條件陳述句可將大類選項篩選掉

觀察分類地址利用if條件陳述句在字典推導式中將風景圖片大類排除掉

def get_meun():
      url = 'https://www.tooopen.com/img'
      res = requests.get(url, headers=headers)
      html = etree.HTML(res.text)
      urls = html.xpath('/html/body/div[3]/div/div/ul/li/a/@href')
      names = html.xpath('/html/body/div[3]/div//div/ul/li/a/text()')
      dic = {k: v for k, v in zip(names, urls) if '_' in v}
      return dic

三、下載圖片

檢查原始碼觀察我們發現
在這里插入圖片描述

所以
進入圖片真正的下載地址尋找高清大圖的下載鏈接

在這里插入圖片描述
此處的url就是我們需要的高清大圖的鏈接下載即可
代碼如下：

# 下載圖片
def download_img(url, start, end):
     count = 0   # 計數   下載多少張圖片
     url1 = url.replace('.aspx', '_1_{}.aspx')# 每頁的真正網頁格式
     img_urls1 = []  #存放圖片下載地址
     img_names = [] 
     for i in range(start, end + 1):
          url2 = url1.format(i)
          res = requests.get(url2, headers=headers).text
          img_url = re.findall(r'a class="pic" href="(.*?)"', res)
          img_name = etree.HTML(res).xpath('/html/body/div[5]/ul/li/div/a/img/@alt')
#          img_names.append(img_name)
#          img_urls1.append(img_url)
          img_urls1 += img_url 
          img_names += img_name
#     print(img_urls1)
#     print(img_names)
     img_urls2 = []
     for j in img_urls1:
           res2 = requests.get(j, headers=headers).text
           img_url2 = etree.HTML(res2).xpath('/html/body/table/tr/td/img/@src')
           #img_url2 = re.findall(r'<img src="(.*?)"  title=' alt=', res2)# 圖片真正的下載鏈接
           img_urls2 += img_url2
#     print(img_urls2)
     for u, n in zip(img_urls2, img_names):
           file_name = n + '.jpg'
           img_content = requests.get(u, headers=headers).content
           with open(path_name + '/' + file_name, 'wb') as f:
                 f.write(img_content)
                 count += 1
                 time.sleep(random.randint(1,2)) #美爬取一張圖片 休眠 防止訪問頻率過快被反爬
     print('\n' + '-' * 15 + ' 已成功為您下載{}張圖片 '.format(count) + '-' * 15 + '\n')

四、輸入我們想要下載圖片的分類和頁數啟動圖片下載器開始下載

def main():  
      pic_dic = get_meun()
      choice = input('請輸入您想下載的圖片型別:')       
      url3 = pic_dic.get(choice)
      print('=' * 15 + ' 圖片下載器啟動 ' + '=' * 15)
      start_page = int(input("請輸入起始頁碼:   "))
      end_page = int(input("請輸入結束頁碼:   "))
      print('~已開始為您下載~')
      download_img(url3, start_page, end_page)

五、為了防止被反爬我們可以多用一些user_agent 偽裝請求頭

user_agent = [
    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/22.0.1207.1 Safari/537.1",
    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.6 (KHTML, like Gecko) Chrome/20.0.1092.0 Safari/536.6",
    "Mozilla/5.0 (Windows NT 6.2) AppleWebKit/536.6 (KHTML, like Gecko) Chrome/20.0.1090.0 Safari/536.6",
    "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/19.77.34.5 Safari/537.1",
    "Mozilla/5.0 (Windows NT 6.0) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.36 Safari/536.5",
    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1063.0 Safari/536.3",
    "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1063.0 Safari/536.3",
    "Mozilla/5.0 (Windows NT 6.2) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1062.0 Safari/536.3",
    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1062.0 Safari/536.3",
    "Mozilla/5.0 (Windows NT 6.2) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1061.1 Safari/536.3",
    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1061.1 Safari/536.3",
    "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1061.1 Safari/536.3",

    "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/535.24 (KHTML, like Gecko) Chrome/19.0.1055.1 Safari/535.24"

import time
import random


# 定義在當前.py檔案的目錄下創建檔案夾
path = os.getcwd()     
path_name = path + '/' + '素材公社'
if not os.path.exists(path_name):
      os.mkdir(path_name)

# 獲取圖片分類選項表單 生成字典
def get_meun():
      url = 'https://www.tooopen.com/img'
      res = requests.get(url, headers=headers)
      html = etree.HTML(res.text)
      urls = html.xpath('/html/body/div[3]/div/div/ul/li/a/@href')
      names = html.xpath('/html/body/div[3]/div//div/ul/li/a/text()')
      dic = {k: v for k, v in zip(names, urls) if '_' in v}
      return dic

# 下載圖片

     count = 0   # 計數   下載多少張圖片
     url1 = url.replace('.aspx', '_1_{}.aspx')# 每頁的真正網頁格式
     img_urls1 = []  #存放圖片下載地址
     img_names = [] 
     for i in range(start, end + 1):
          url2 = url1.format(i)
          res = requests.get(url2, headers=headers).text
          img_url = re.findall(r'a class="pic" href="(.*?)"', res)
          img_name = etree.HTML(res).xpath('/html/body/div[5]/ul/li/div/a/img/@alt')
#          img_names.append(img_name)
#          img_urls1.append(img_url)
          img_urls1 += img_url 
          img_names += img_name
#     print(img_urls1)
#     print(img_names)
     img_urls2 = []
     for j in img_urls1:
           res2 = requests.get(j, headers=headers).text
           img_url2 = etree.HTML(res2).xpath('/html/body/table/tr/td/img/@src')
           #img_url2 = re.findall(r'<img src="(.*?)"  title=' alt=', res2)# 圖片真正的下載鏈接
           img_urls2 += img_url2
#     print(img_urls2)
     for u, n in zip(img_urls2, img_names):
           file_name = n + '.jpg'
           img_content = requests.get(u, headers=headers).content
           with open(path_name + '/' + file_name, 'wb') as f:
                 f.write(img_content)
                 count += 1
                 time.sleep(random.randint(1,2)) #美爬取一張圖片 休眠 防止訪問頻率過快被反爬
     print('\n' + '-' * 15 + ' 已成功為您下載{}張圖片 '.format(count) + '-' * 15 + '\n')
