如何在API调用中过滤带有扩展名的文件名? [英] How to filter filenames with extension on API call?

问题描述

我正在使用python confluence API，用于从confluence页面下载附件，我只需要下载扩展名为 .mpp 的文件.尝试使用 glob 和直接参数，但是没有用.

I was working on the python confluence API for downloading attachment from confluence page, I need to download only files with .mpp extension. Tried with glob and direct parameters but didnt work.

这是我的代码:

file_name = glob.glob("*.mpp")
attachments_container = confluence.get_attachments_from_content(page_id=33110, start=0, limit=1,filename=file_name)
print(attachments_container)
attachments = attachments_container['results']
for attachment in attachments:
    fname = attachment['title']
    download_link = confluence.url + attachment['_links']['download']
    r = requests.get(download_link, auth = HTTPBasicAuth(confluence.username,confluence.password))
    if r.status_code == 200:
        if not os.path.exists('phoenix'):
            os.makedirs('phoenix')
        fname = ".\\phoenix\\" +fname

推荐答案

glob.glob() 在您的 local 文件夹中运行.因此，您不能将其用作 get_attachments_from_content()的过滤器.另外，请不要指定 limit ，因为这样只会使您获得第一个附件.指定一个上限，或者任何默认值都将包括所有这些上限.(您可能需要对结果进行分页.)

glob.glob() operates on your local folder. So you can't use that as a filter for get_attachments_from_content(). Also, don't specify a limit of since that gets you just one/the first attachment. Specify a high limit or whatever default will include all of them. (You may have to paginate results.)

但是，您可以通过在下载每个附件之前检查它们的 title 来排除不需要的文件，这些文件的格式为 fname = attachment ['title'] .

However, you can exclude the files you don't want by checking the title of each attachment before you download it, which you have as fname = attachment['title'].

attachments_container = confluence.get_attachments_from_content(page_id=33110, limit=1000)
attachments = attachments_container['results']
for attachment in attachments:
    fname = attachment['title']
    if not fname.lower().endswith('.mpp'):
        # skip file if it's not got that extension
        continue
    download_link = ...
    # rest of your code here

此外，您的代码看起来像是从此答案中复制粘贴，但是您已更改了实际的下载";一部分.因此，如果您的下一个StackOverflow问题将是如何从融合中下载文件"，请使用该答案的代码.

Also, your code looks like a copy-paste from this answer but you've changed the actual "downloading" part of it. So if your next StackOverflow question is going to be "how to download a file from confluence", use that answer's code.
