为什么当我运行脚本时,下载的图像文件的字节数为零,并且收到属性错误?

我还是python的新手,并尝试通过构建一些脚本来进行练习。这个人应该在图像subreddit中找到热提交,然后使用提交URL的基本名称将这些图像下载到redditpics dir路径。我正在使用python 3.7。首先,我尝试了这个:

import praw, requests, os, bs4

reddit = praw.Reddit(client_id='xxxx', 
                      client_secret='xxxx',
                      user_agent='picture downloader',
                      username='xxxx',
                      password='xxxx'
                      ) 
print(reddit.read_only)

os.makedirs('redditpics', exist_ok=True) 
for submission in reddit.subreddit('earthporn').hot(limit=50):
    url = submission.url
    print(url)
    imageFile = open(os.path.join('redditpics', os.path.basename(url)), 'wb')
print('Done')

下载的图像的信息字节为零。然后我从无聊的东西自动化中添加了以下内容:

imageFile = open(os.path.join('redditpics', os.path.basename(url)), 'wb')
for chunk in url.iter_content(100000):
    print("saving " + imageFile)

    imageFile.write(chunk)
imageFile.close()
print('Done.')

但是出现以下错误:AttributeError: 'str' object has no attribute 'iter_content'
