前言

马上要中秋节了，白又白开始给各位看官准备好了月饼，有了月饼我们就的赏月了，赏月好像或多或少有点单调哈，那我们先赏嫦娥姐姐（本来白又白是想自己画嫦娥的，但是实在复杂就放弃了）

采集数据目标

网址：百度图片
中秋节的福利：爬取全网嫦娥仙子图片下载，你喜欢哪种？_Python入门

工具使用

开发工具：pycharm
开发环境：python3.7， Windows10
使用工具包：requests

项目思路解析

图片数据皆来自于百度图片，在采集数据之前需要先区分网页的数据格式，是静态数据还是动态数据，当前网页加载数据需要鼠标下拉请求，数据明显是动态的，动态数据需要通过抓包工具进行获取

请求的接口里有对应图片链接，思路清晰准备编写代码
1.获取到url地址通过requests发送网络请求，请求时需要注意请求头因为百度图片也是采集的数据，会有网页重定向

# 添加请求头
headers = {
    # cookie信息
    "Cookie": "BDqhfp=%E6%98%8E%E6%98%9F%E5%8D%95%E4%BA%BA%E7%85%A7%26%260-10-1undefined%26%261132%26%263; PSTM=1606885275; BAIDUID=D9B7A2A3C7555B9A30BC448DE032D13B:FG=1; BIDUPSID=5EEB8A912FC8FDCB0C187D519FABA455; BDORZ=B490B5EBF6F3CD402E515D22BCDA1598; BDSFRCVID=RxtOJeC62CaLjt3rvnJAhLqAYfS_AG3TH6ao5bUjY3stbaPxsXJ7EG0P8f8g0KubzcDrogKKLmOTHpKF_2uxOjjg8UtVJeC6EG0Ptf8g0f5; H_BDCLCKID_SF=tJPD_CLKtDI3fP36qRQtbt00qxby26nfa6T9aJ5nJDoNqIopb5bK54CkXM7rbxok3gQ3Lqo8QpP-HJ7zbxRqQhkD3NQXJU3p2erEKl0MLU7tbb0xynoDMbtNMfnMBMnramOnaPJc3fAKftnOM46JehL3346-35543bRTLnLy5KJYMDF4jj-hj5QLjaRf-b-X2CjyWb88Kb7VbUo95MnkbfJBD4bKWPTJt5rqWqcp2pRaEfTI0pnNQTt7yajK25QaQCQko-O2KJjmJ-Oyy6JpQT8reMDOK5OibCrE3hb-ab3vOpRzXpO1KMPzBN5thURB2DkO-4bCWJ5TMl5jDh3Mb6ksDMDtqtJHKbDDVILMJMK; BDUSS=g5U3pnMlhCRWJWT1lYQzR3SVBuSUN0MUNkWERaSDJHV2xKN3NHUDJzMFhGZTlmRUFBQUFBJCQAAAAAAAAAAAEAAAAIs6iyAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABeIx18XiMdfRE; BDUSS_BFESS=g5U3pnMlhCRWJWT1lYQzR3SVBuSUN0MUNkWERaSDJHV2xKN3NHUDJzMFhGZTlmRUFBQUFBJCQAAAAAAAAAAAEAAAAIs6iyAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABeIx18XiMdfRE; delPer=0; PSINO=6; __yjsv5_shitong=1.0_7_65901da49a5a59037e920cbd2020d5073dda_300_1606918958343_113.240.215.138_cdf8224b; H_PS_PSSID=1468_32855_33059_33098_33100_33199_33147_22160; BA_HECTOR=20050k2gakah8100r71fsguaf0q; BDRCVFR[X_XKQks0S63]=mk3SLVN4HKm; firstShowTip=1; cleanHistoryStatus=0; BDRCVFR[dG2JNJb_ajR]=mk3SLVN4HKm; userFrom=tupian.baidu.com; BDRCVFR[-pGxjrCMryR]=mk3SLVN4HKm; indexPageSugList=%5B%22%E6%98%8E%E6%98%9F%E5%8D%95%E4%BA%BA%E7%85%A7%22%2C%22%E6%98%8E%E6%98%9F%22%5D",

获取的数据为json数据转换成字典直接获取里面的图片url

 # 正则匹配数据
    url_list = re.findall('"thumbURL":"(.*?)",', response.text)

    print(url_list)

对图片网址发送网络请求，用网络地址保存对应图片名字
