执行后403 Forbidden
是猫眼更行了反扒策略吗?
经过多次尝试使用requests
请求详情页,发现最少发生一次重定向,最多三次,重定向路径为
[http://taobao.com/group/xxxxxxx -> http://www.taobao.com/group/xxxxxxx -> https://www.taobao.com/group/xxxxxx -> https://www.taobao.com/axxxxxxxx]
这种情况导致在获取html代码的时候无法获取到最终url的代码怎么解决?所以无法正常找到想要的内容
我自己是把从 article_url
获取到的 url
中的 group/
替换成 a
就能正常访问了。
url = 'http://toutiao.com/group/6444359581934141710/'
url = url.replace('group/', 'a')
代码修正后:cnsimo/toutiao
自己在存储前加了一个目录判断,程序可以正常运行,但是下载图片结果是每篇文章只有一张图片被下载存储。代码如下:
def save_images(content, page, title):
dir_path = '{0}/{1}/{2}/{3}'.format(os.getcwd(), 'images',page//20, title)
if not os.path.exists(dir_path):
os.makedirs(dir_path)
file_path = '{0}/{1}.{2}'.format(dir_path, md5(content).hexdigest(), 'jpg')
if not os.path.exists(file_path):
with open(file_path, 'wb') as f:
f.write(content)
f.close()
求问,为什么照着您的教程敲得正则代码,在pycharm中要不就是一直运行没有结果,要不就是结果为空,我也对照了新的网页代码(猫眼电影和豆瓣),求教,是否是pycharm问题或者是什么?多谢了。
