通过BingAPI爬取Bing半个月内壁纸

一、前言
二、爬虫代码
三、代码说明

一、前言

爬取Bing搜索网站首页壁纸的方式主要有两种，第一种为间接爬取，即并不直接对Bing网站发起请求，而是对那些收集汇总了Bing壁纸的网站发起请求，爬取图片。第二种为直接爬取，即直接对Bing网站发起访问。

本文使用第二种，通过Bing官方提供的一种API进行壁纸下载，通过这种方式可以下载从下载当天起半个月内Bing搜索网站首页使用过的壁纸。
在这里插入图片描述

二、爬虫代码

import requests
import os

import time

colorama.init(autoreset = True)

    if save_folder_path is None:
        save_folder_path = 'bing壁纸图片'
    if not os.path.exists(save_folder_path):
        os.mkdir(save_folder_path)

            img_num += 1
            time.sleep(1)
