url = 'http://photo.weibo.com/photos/get_all?uid=1223178222&album_id=3562507013282779&count=30&page=1&type=3&__rnd=1550915606445'
#headers作用为反爬
headers = {
        'Cookie':'login_sid_t=3e61e90db210e2d865cfe38b9f68b3e8; cross_origin_proto=SSL; _s_tentry=passport.weibo.com; Apache=2024617387008.776.1550912473467; SINAGLOBAL=2024617387008.776.1550912473467; ULV=1550912473477:1:1:1:2024617387008.776.1550912473467:; SSOLoginState=1550912517; SCF=AuK3Eq-JkG6jrMruEXJ9RR0OCRGsrMU-V0Ay0uXxQeNipn2-icVEfnyWzgroN6QNKAdKbeSH4t8hRVBs0N58LJU.; SUB=_2A25xdXxWDeRhGeNI7VYR8ibLzDmIHXVSA-qerDV8PUNbmtBeLWShkW9NSFL5eoIO_K5uDxqPlhiBWoGNMcTx70v-; SUBP=0033WrSXqPxfM725Ws9jqgMF55529P9D9WhYGb4-SAp5obSm.ebeXpMd5JpX5K2hUgL.Fo-cSoB7eonNS0-2dJLoIp7LxKML1KBLBKnLxKqL1hnLBoMfSoqXehzRS0Mf; SUHB=06Z1Udp4kRlhNk; ALF=1582448517; un=13836767328; wvr=6; ULOGIN_IMG=15509128764705; UOR=,,www.sogou.com; PHOTO-G0=8aae608225ce51dc489d4de036180247; WBStorage=201902231752|undefined; webim_unReadCount=%7B%22time%22%3A1550915600809%2C%22dm_pub_total%22%3A0%2C%22chat_group_pc%22%3A0%2C%22allcountNum%22%3A6%2C%22msgbox%22%3A0%7D',

        }
#数据为json格式
response = requests.get(url,headers = headers).json()
#print(response)
#new_url = pic_host+/sq612/+pic_name
pic_host = response['data']['photo_list'][0]['pic_host']  #按照所属关系得到pic_host
middle = '/sq612/'
pic_name = response['data']['photo_list'][0]['pic_name']
#print(pic_host)
#print(pic_name)

new_url = '%s%s%s'%(pic_host,middle,pic_name)  #将三者连接得到图片链接
#print(new_url)

r = requests.get(new_url)
#保存图片
with open('huge.jpg','wb') as f:
    f.write(r.content)   #写入图片，文本为text，图片为content

结果：
