AttributeError：“ dict”对象在检查图片网址时没有属性“ decode”

问题描述

我正在尝试检查360,000个图像URL的列表并计算有效图像。如果范围是1000个项目，则下面的迭代效果很好，但是如果将范围提高到5000或更多，它将显示错误“ AttributeError：'dict'对象没有属性'decode'”。

谁能帮助我修复错误和/或修改代码以一次运行遍历所有360,000个URL？非常感谢！

# Here's my codes

cnt_1 = 0

for post in list_post[0:5000]:
    try:
        url = post['photo_url']
        parse_object = urlparse(url)
        conn = http.client.HTTPConnection(parse_object.netloc)
        conn.request('HEAD',parse_object.path)
        response = conn.getresponse()
        conn.close()
        if (response.status == 200):
            cnt_1 += 1
    except AttributeError:
        continue
