需求:
我爬取的图片是bytes格式,需要直接存到本地。

import urllib3
import os
#PIL图像处理标准库
from PIL import Image
from io import BytesIO
http = urllib3.PoolManager()
response = http.request( 'GET' , 'f.hiphotos.baidu.com/image/pic/item/8d5494eef01f3a29f863534d9725bc315d607c8e.jpg' )
result = response.data
#将bytes结果转化为字节流
bytes_stream = BytesIO(result)
#读取到图片
roiimg = Image. open (bytes_stream)
# roiimg.show() #展示图片
#print(type(result))
#print(response.status)
imgByteArr = BytesIO() #初始化一个空字节流
roiimg.save(imgByteArr, format ( 'PNG' )) #把我们得图片以‘PNG'保存到空字节流
imgByteArr = imgByteArr.getvalue() #无视指针,获取全部内容,类型由io流变成bytes。
# dir_name = os.mkdir('baiduimg')
img_name = '1.jpg'
with open (os.path.join( 'baiduimg' ,img_name), 'wb' ) as f:
f.write(imgByteArr)

补充:python3保存请求中的byte图片流到本地

def getImage():

方法一,使用urllib.urlretrieve()

import urllib
# 网络上图片的地址
img_src = 'https://www.baidu.com/img/bd_logo1.png?where=super'
# 将图片下载到本地
urllib.urlretrieve(img_src, 'D:/images/1.jpg' )
|
方法二,使用PIL+requests:

import requests
from PIL import Image
from io import BytesIO
response = requests.get(img_src)
image = Image. open (BytesIO(response.content))
image.save( 'D:/images/1.jpg' )

以上为个人经验,希望能给大家一个参考,也希望大家多多支持服务器之家。如有错误或未考虑完全的地方,望不吝赐教。
