Google 幻灯片 returns 'The provided image is in an unsupported format' 即使配置了授权字段

Question

最近的线程是

但我不想打开与世界其他地方分享的图像。所以我配置域

file_id = uploaded_file.get('id')
drive_service.permissions().create(fileId=file_id, body={
    'type': 'domain',
    'domain': 'mydomain.com', # this is the domain I use the gsuite user e.g. richard@mydomain.com to login
    'role': 'reader'
}).execute()

幻灯片资源由

构建

def build_request(http, *args, **kwargs):
    import google_auth_httplib2
    new_http = google_auth_httplib2.AuthorizedHttp(credentials=drive_creds)
    auth_header = {
        'Authorization': 'Bearer '+ drive_creds.token
    }
    headers = kwargs.get('headers', {})
    if not headers:
        kwargs['headers'] = auth_headers
    else:
        kwargs['headers'].update(auth_header)
    http_req = googleapiclient.http.HttpRequest(new_http, *args, **kwargs)
    return http_req
slides_service = build('slides', 'v1', credentials=slides_creds, requestBuilder=build_request)

执行时我可以观察到 kwargs 被传递给 HttpRequest，授权字段配置正确，如

{'headers': {'Authorization': 'Bearer <google drive token>', ... }

但是在执行期间，创建图像功能（我确定我的创建图像功能可以正常工作，因为一旦我使用 public 可访问图像，例如 google 徽标，将图像发布到google 幻灯片页）总是 returns 状态代码 400 和消息 'The provided image is in an unsupported format'。我打开一个私人 window 并粘贴 link，看起来它仍然被重定向到登录页面的请求。

我需要配置任何其他步骤才能完成这项工作吗？非常感谢您的帮助。

更新 2:

当切换到使用本地 http 服务器提供图像时（可以通过 http://<intranet ip or localhost>:<port>/path/to/img.png、google 幻灯片 api returns 跟随错误

"Invalid requests[0].createImage: There was a problem retrieving the image. The provided image should be publicly accessible, within size limit, and in supported formats."

这让我想知道也许 google slide API 不再允许以特殊权限（例如域）访问 webContentLink。只允许 public 可访问 url。

更新 3:

create_image函数参数：
- slide_object_id: g6f1c6c22f2_1_69
- web_content_link: https://drive.google.com/a/{{域名}}/uc?id={{图片id}}&export=download
- 尺寸：{'height'：{'magnitude'：10800，'unit'：'EMU'}，'width'：{'magnitude': 19800, 'unit': 'EMU'}}
- 转换：{'scaleY'：171.9097，'scaleX'：212.4558，'translateY'：937125，'translateX'：2347875，'unit' : 'EMU'}

Answer 1

问题：

只有可公开访问 URL 的图像才能添加到幻灯片中。与发出请求的帐户共享图像是不够的。正如您在 the official documentation:

中看到的

If you want to add private or local images to a slide, you'll first need to make them available on a publicly accessible URL.

解决方法：

如 Tanaike's answer 中所述，您可以做的是：(1) 公开分享图像，(2) 使用可公开访问的 URL，并且（3）删除在步骤 1 中创建的权限。这样，图像仅在程序执行步骤 2 和 3 的短时间内可公开访问。
参考文档中提供的另一个选项是：

upload your images to Google Cloud Storage and use signed URLs with a 15 minute TTL. Uploaded images are automatically deleted after 15 minutes.
