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
