buf = response.read()
buf = buf.decode('utf-8')

f?= open(str(i)+'.jpg','w')改成f = open(str(i)+'.jpg','wb'),wb是以二進制形式寫入就可以了，這樣就不會出現亂碼了。

? ?windows的話可以這樣指定路徑?????path = 'E:\\python\\'? ? path += str(i) + '.jpg'? ? print (path)? ? f = open(path,'wb')Linux的話這樣path = '/tmp/' + str(i) +'.jpg'f=open(path,'w')
