我正在开发一个项目,我需要使用python下载一些图像。我试图通过做不同的事情来修复它,但它仍然无法正常工作。这是我发现的一些代码,我尝试使用但它似乎不起作用。说实话,我是编程的新手,所以我很乐意得到一些帮助。
以下是代码:
import json
import os
import time
import requests
import Image
from StringIO import StringIO
from requests.exceptions import ConnectionError
def go(query,pathA):
BASE_URL = 'https://ajax.googleapis.com/ajax/services/search/images?'\
'v=1.0&q=' + query + '&start=%d'
BASE_PATH = os.path.join(pathA, query)
if not os.path.exists(BASE_PATH):
os.makedirs(BASE_PATH)
start = 0
while start < 60:
r = requests.get(BASE_URL % start)
for image_info in json.loads(r.text)['responseData']['results']:
url = image_info['unescapedUrl']
try:
image_r = requests.get(url)
except ConnectionError, e:
print 'could not download %s' % urla
continue
# Remove file-system path characters from name.
title = image_info['titleNoFormatting'].replace('/', '').replace('\\', '')
fileII = open(os.path.join(BASE_PATH, '%s.jpg') % title, 'w')
try:
Image.open(StringIO(image_r.content)).save(fileII, 'JPEG')
except IOError, e:
# Throw away some gifs...blegh.
print 'could not save %s' % url
continue
finally:
fileII.close()
print start
start += 4 # 4 images per page.
time.sleep(1.5)
# Example use
go('landscape', 'myDirectory')
运行上述代码时出现的错误是:
IOError: [Errno 22] invalid mode ('w') or filename: u'myDirectory\landscape\Na
ture - Photo gallery | MIRIADNA.COM.jpg'
提前致谢
答案 0 :(得分:1)
这段代码定义了保存图像的位置
# Remove file-system path characters from name.
title = image_info['titleNoFormatting'].replace('/', '').replace('\\', '')
阅读您的错误消息我看到该文件不存在(或目录),因为w
是打开文件的有效模式。
尝试将标题硬编码为简单的本地路径,例如
title = 'test'
