爬虫获取所有图片：

背景：

最近做一些Web题，发现了些网页的背景会随机出现，每一次刷新都会出现不一样的图，感觉有点意思，试着研究下，当然，肯定不是研究咋弄的这个，而是，api里的图怎么爬取：

首先：

接口文档如下：

[LoliApi]: https://docs.loliapi.com/api-shi-yong-wen-dang/sui-ji-er-ci-yuan-tu-pian “LoliApi”

之后直接上源码：

import requests
import os

def pe():
    for i in range(1,3400):
        url = "https://img.loliapi.cn/i/pe/img{}.webp".format(str(i))
        print(url)
        resp = requests.get(url)
        if resp.status_code == 404:
            break
        if os.path.exists("./img/pe/img{}.webp".format(i)):
            print("./img/pe/img{}.webp已存在".format(i))
            pass
        else:
            with open("./img/pe/img{}.webp".format(i), 'wb') as f:
                f.write(resp.content)

def pc():
    for i in range(690,1000):
        url = "https://img.loliapi.cn/i/pc/img{}.webp".format(str(i))
        print(url)
        resp = requests.get(url)
        if resp.status_code == 404:
            break
        if os.path.exists("./img/pc/img{}.webp".format(i)):
            print("./img/pc/img{}.webp已存在".format(i))
            pass
        else:
            with open("./img/pc/img{}.webp".format(i),'wb') as f:
                f.write(resp.content)


if __name__ == '__main__':
    model = int(input())
    if model == 1:
        pc()
    elif model == 0:
        pe()
