--- theme: smartblue --- > 最近用uniapp白嫖阿里云数据库搞了个壁纸小程序，但是没有壁纸可以放进去呀。。那就只能捡起我的老本行 - python爬APP的壁纸图片了~~ ### 安装python环境第一步肯定是安装一个python环境啦。。因为用的是mac，会自带python2.7。。就不多说了，可以自行搜索安装方法的。其次就是安装IDE啦。推荐：pycharm，如果你想用txt文本写也可以。 ### 开始写代码啦先格式化代码 `#coding=utf-8` 这句话必须要写在第一行，不然会将中文解析成乱码引入需要的包 ``` import requests improt time ``` 定义header，便于识别非爬虫请求接口 ``` 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' } ``` ### 进入正题了先定义需要的参数 ``` pn = 30 // 接口每页返回的条数，后面需要累加的，每次累加30 page = 100 // 需要爬取的页数 ``` 开始循环页数去爬取壁纸图片啦 ``` for p in range(1, page): url = 'http://service.picasso.adesk.com/v1/vertical/category/4e4d610cdf714d2966000000/vertical?' # 最新 order: new # 热门 order: hot param = { // 请求时需要的参数 'limit': 30, // 每页固定返回30条 'skip': pn, 'adult': 'false', 'first': 0, 'order': 'hot' // 分类：hot是热门，new是最新 } #将编码形式转换为utf-8 page_text = requests.get(url=url,headers=header,params=param) page_text.encoding = 'utf-8' page_text = page_text.json() print page_text ``` 打印出来的数据如下： ``` {u'msg': u'success', u'res': {u'vertical': [{u'preview': u'http://img5.adesk.com/61d69b54e7bce723c6228a33?sign=57874bf4857d4df11ae166410150b115&t=621ce303', u'thumb':
