PK创意闹新春，我正在参加「春节创意投稿大赛」，详情请看：春节创意投稿大赛
前言
2022 虎年大吉，共迎新春，新的一年，我希望通过”万虎“拼福字以及”万福“拼萌虎的方式，给大家带来好运，祝大家虎虎生威，顺风顺水，人生如意，财源滚滚！恭喜完了，下面就要亮技术了~
一、爬取福虎
通过 Python 爬虫技术，我们可以很方便快捷的从百度图片爬取到大量虎和福的图片，下面演示一下如何爬取：
1、网站分析
首先，我们打开百度图片，F12 打开控制台，然后搜索一个 ”虎年“，点击图片：
在滑动鼠标加载更多图片的同时，我们查看控制台中输出的内容，可以发现有很多数据包：
这里随便选择一条，并复制这个数据包的 URL 请求：
https://image.baidu.com/search/acjson?tn=resultjson_com&logid=11365856357363949053&ipn=rj&ct=201326592&is=&fp=result&fr=&word=%E8%99%8E%E5%B9%B4&queryWord=%E8%99%8E%E5%B9%B4&cl=2&lm=-1&ie=utf-8&oe=utf-8&adpicid=&st=-1&z=&ic=0&hd=&latest=©right=&s=&se=&tab=&width=&height=&face=0&istype=2&qc=&nc=1&expermode=&nojc=&isAsync=&pn=120&rn=30&gsm=78&1642056713314=
点开这个 URL 看到其携带的参数，复制这一段：
tn: resultjson_com
logid: 11365856357363949053
ipn: rj
ct: 201326592
is:
fp: result

word: 虎年
queryWord: 虎年
cl: 2
lm: -1
ie: utf-8
oe: utf-8
adpicid:

qc:
nc: 1
expermode:
nojc:
isAsync:
pn: 120
rn: 30
gsm: 78
1642056713314:
至此，我们已经获取到所需的代码，分析结束！
2、爬取代码
关于代码编写部分的详细步骤我就不做描述了，以下分享下主要源码：
import requests
import os
from lxml import etree
path = r"/Users/lpc/Downloads/baidu1/"
# 判断目录是否存在，存在则跳过，不存在则创建
if os.path.exists(path):
pass
else:
os.mkdir(path)
page = input('请输入要爬取多少页：')
page = int(page) + 1
header = {
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 11_1_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36'
}
n = 0
pn = 1
# pn是从第几张图片获取 百度图片下滑时默认一次性显示30张
for m in range(1, page):
url = 'https://image.baidu.com/search/acjson?'
param = {
'tn': 'resultjson_com',
'logid': '7680290037940858296',
'ipn': 'rj',
'ct': '201326592',
'is': '',
'fp': 'result',
'queryWord': '虎年',
'cl': '2',
'lm': '-1',
'ie': 'utf-8',
'oe': 'utf-8',
'adpicid': '',
'st': '-1',
'z': '',
'ic': '0',
'hd': '1',
'latest': '',
'copyright': '',
'word': '虎年',
's': '',
'se': '',
'tab': '',
'width': '',
'height': '',
'face': '0',
'istype': '2',
'qc': '',
'nc': '1',
'fr': '',
'expermode': '',
'nojc': '',
'acjsonfr': 'click',
'pn': pn, # 从第几张图片开始
'rn': '30',
'gsm': '3c',
'1635752428843=': '',
}
page_text = requests.get(url=url, headers=header, params=param)
page_text.encoding = 'utf-8'
page_text = page_text.json()
print(page_text)
# 先取出所有链接所在的字典，并将其存储在一个列表当中
info_list = page_text['data']
# 由于利用此方式取出的字典最后一个为空，所以删除列表中最后一个元素
del info_list[-1]
# 定义一个存储图片地址的列表
img_path_list = []
for i in info_list:
img_path_list.append(i['thumbURL'])
# 再将所有的图片地址取出，进行下载
# n将作为图片的名字
for img_path in img_path_list:
img_data = requests.get(url=img_path, headers=header).content
img_path = path + str(n) + '.jpg'
with open(img_path, 'wb') as fp:
fp.write(img_data)
n = n + 1
pn += 29
以上方式可以实现爬取百度图片，但是每次都要去分析爬取，比较麻烦且不智能，因此再分享一个运行后只需要输入关键词 “虎年” 即可爬取的源码：
# -*- coding:utf-8 -*-
import requests
import re, time, datetime
import os
import random
import urllib.parse
from PIL import Image # 导入一个模块
imgDir = r"/Volumes/DBA/python/img/"
# 设置headers 为了防止反扒，设置多个headers
# chrome，firefox，Edge
headers = [
{

}
]
picList = [] # 存储图片的空 List
keyword = input("请输入搜索的关键词：")
kw = urllib.parse.quote(keyword) # 转码
# 获取 1000 张百度搜索出来的缩略图 list
def getPicList(kw, n):
global picList
weburl = r"https://image.baidu.com/search/acjson?tn=resultjson_com&logid=11601692320226504094&ipn=rj&ct=201326592&is=&fp=result&queryWord={kw}&cl=2&lm=-1&ie=utf-8&oe=utf-8&adpicid=&st=&z=&ic=&hd=&latest=©right=&word={kw}&s=&se=&tab=&width=&height=&face=&istype=&qc=&nc=1&fr=&expermode=&force=&cg=girl&pn={n}&rn=30&gsm=1e&1611751343367=".format(
kw=kw, n=n * 30)
req = requests.get(url=weburl, headers=random.choice(headers))
req.encoding = req.apparent_encoding # 防止中文乱码
webJSON = req.text
imgurlReg = '"thumbURL":"(.*?)"' # 正则
picList = picList + re.findall(imgurlReg, webJSON, re.DOTALL | re.I)
for i in range(150): # 循环数比较大，如果实际上没有这么多图，那么 picList 数据不会增加。
getPicList(kw, i)
for item in picList:
# 后缀名 和名字
itemList = item.split(".")
hz = ".jpg"
picName = str(int(time.time() * 1000)) # 毫秒级时间戳
# 请求图片
imgReq = requests.get(url=item, headers=random.choice(headers))
# 保存图片
with open(imgDir + picName + hz, "wb") as f:
f.write(imgReq.content)
# 用 Image 模块打开图片
im = Image.open(imgDir + picName + hz)
bili = im.width / im.height # 获取宽高比例，根据宽高比例调整图片大小
newIm = None
# 调整图片的大小，最小的一边设置为 50
if bili >= 1:
newIm = im.resize((round(bili * 50), 50))
else:
newIm = im.resize((50, round(50 * im.height / im.width)))
# 截取图片中 50*50 的部分
clip = newIm.crop((0, 0, 50, 50)) # 截取图片,crop 裁切
clip.convert("RGB").save(imgDir + picName + hz) # 保存截取的图片
print(picName + hz + " 处理完毕")
演示一下此种方式，运行后输入 “虎年” 回车等待下载完成即可：
以上就是爬取百度图片的源码，分别爬取 “福” 和 “虎” 之后，我们就可以开始万图成像啦！
二、万图成像
万图成像很简单，之前我也写过一篇类似的文章有介绍过：Python 批量爬取猫咪图片实现千图成像 ，可以参考一下！
效果图
下面直接上传我们拼好的效果图：
三、我用SQL写福字
SQL如下：
create table LuciferFu(fu_line varchar2(128));
insert into LuciferFu values

感兴趣的朋友可以自己试试，玩转虎年！
