还是直接上代码：

import requests
import os
import json

for i in range(1,200):
    res = requests.get("https://dog.ceo/api/breeds/image/random");

    print(res.status_code)
    print(res.text)

    json2python = json.loads(res.text)

    default_info = '当前的 key 不存在'
    url = json2python.get('message', default_info)
   
    print(url)

    h={'User-Agent: Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Mobile Safari/537.36'}

    d='D:\\A\\'

    path=d+"f"+ str(i)+".jpg"
    print(path)

    if not os.path.exists(d):
        os.mkdir(d)

    r=requests.get(url)
    if(r.status_code==200):

        r.raise_for_status()

        with open(path,'wb') as f:
            f.write(r.content)
            f.close()
            print("保存成功")
