google-drive-api - 即使配置了授权字段，Google 幻灯片也会返回“提供的图像格式不受支持”

问题描述

最接近的线程是

https://stackoverflow.com/questions/60160794/getting-the-provided-image-is-in-an-unsupported-format-error-when-trying-to-in

但我不想打开与世界其他地方共享它的图像。所以我用域配置

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

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 并正确配置了授权字段，例如

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

但是在执行过程中，创建图像功能（我确信我的创建图像功能正常工作，因为一旦我使用公共可访问图像，例如谷歌徽标，将图像发布到谷歌幻灯片页面就没有问题）总是返回状态代码 400 和消息'提供的图像格式不受支持”。我打开一个私人窗口并粘贴链接，看起来它仍然重定向了登录页面的请求。

我需要配置任何其他步骤才能完成这项工作？非常感谢您的帮助。

更新 1：

下面的代码用于创建相应的幻灯片并基于 google doc 驱动资源。

    return http_req
slides_service = build('slides', 'v1', credentials=slides_creds, requestBuilder=build_request)
drive_service = build('drive', 'v3', credentials=drive_creds)

更新 2：

切换到使用本地 http 服务器提供图像时（可通过访问http://<intranet ip or localhost>:<port>/path/to/img.png，google slide api 返回以下错误

"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."

这让我想知道也许谷歌幻灯片 API 不再允许使用特殊权限（例如域）访问 webContentLink。只允许公开访问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={{image id}}&export=download
- 尺寸：{'高度'：{'幅度'：10800，'单位'：'EMU'}，'宽度'：{'幅度'：19800，'单位'：'EMU'}}
- 变换：{'scaleY'：171.9097，'scaleX'：212.4558，'translateY'：937125，'translateX'：2347875，'unit'：'EMU'}
