python下载图片到文件夹_Python下载图片并保存本地的四种方法

一:使用Python中的urllib类中的urlretrieve()函数,直接从网上下载资源到本地,具体代码:

import os,stat

import urllib.request

img_url="https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1516371301&di=d99af0828bb301fea27c2149a7070" \

"d44&imgtype=jpg&er=1&src=http%3A%2F%2Fupload.qianhuaweb.com%2F2017%2F0718%2F1500369506683.jpg"

file_path='D:/book/img'

file_name ="pyt"

try:

#是否有这个路径

if not os.path.exists(file_path):

#创建路径

os.makedirs(file_path)

#获得图片后缀

file_suffix = os.path.splitext(img_url)[1]

print(file_suffix)

#拼接图片名(包含路径)

filename = '{}{}{}{}'.format(file_path,os.sep,file_name,file_suffix)

print(filename)

#下载图片,并保存到文件夹中

urllib.request.urlretrieve(img_url,filename=filename)

except IOError as e:

print("IOError")

except Exception as e:

print("Exception")

二:利用读写操作写入文件,具体代码:

import os,stat

import urllib.request

for i in range(1,3):

if not os.path.exists("./rym"):

print("不纯在")

os.makedirs("./rym")

else:

print("存在")

os.chmod("D:/imagss",777)

with urllib.request.urlopen("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1516371301&di=d99af0828b"

"b301fea27c2149a7070d44&imgtype=jpg&er=1&src=http%3A%2F%2Fupload.qianhuaweb.com%2F2017%2F0718%"

"2F1500369506683.jpg", timeout=30) as response, open("./rym/lyj.png"

, 'wb') as f_save:

f_save.write(response.read())

f_save.flush()

f_save.close()

print("成功")

三:以二进制方式写入文件即可

f = open(r"E:\Picture\0.png",'wb')#注意写入方式

f.write(urllib2.urlopen(url).read())

f.close()

四:调用urllib库函数

urllib.urlretrieve(url,"E:\Picture\%s.jpg"%0)

以上两种方式保存的图片路径均为E:\Picture\0.png
