如何使用 python 在 Microsoft Graph 中显示用户图像

Question

我试过使用 GET https://graph.microsoft.com/v1.0/me/photo/$value 获取用户的 image/photo 但它仅 returns 一个 HTTP 200 状态代码。如何获取二进制数据？

我也试过使用 content.property as suggested in a similar post 但得到的 .format 不是字典的属性。

@app.route("/photo")
def get_photo():
    token = _get_token_from_cache(app_config.SCOPE)
    if not token:
        return redirect(url_for("login"))
    photo = requests.get(app_config.PHOTO_ENDPOINT,  
            headers={'Authorization': 'Bearer ' + token['access_token']})
    print(photo.status_code)
    return photo

获取个人资料照片，并可选择保存本地副本。 Returns 原始照片数据、HTTP 状态代码、内容类型和保存的文件名的元组。参考这个sample.

def profile_photo(session, *, user_id='me', save_as=None):
    """Get profile photo, and optionally save a local copy.
    session = requests.Session() instance with Graph access token
    user_id = Graph id value for the user, or 'me' (default) for current user
    save_as = optional filename to save the photo locally. Should not include an
              extension - the extension is determined by photo's content type.
    Returns a tuple of the photo (raw data), HTTP status code, content type, saved filename.
    """

    endpoint = 'me/photo/$value' if user_id == 'me' else f'users/{user_id}/$value'
    photo_response = session.get(api_endpoint(endpoint),
                                 stream=True)
    photo_status_code = photo_response.status_code
    if photo_response.ok:
        photo = photo_response.raw.read()
        # note we remove /$value from endpoint to get metadata endpoint
        metadata_response = session.get(api_endpoint(endpoint[:-7]))
        content_type = metadata_response.json().get('@odata.mediaContentType', '')
    else:
        photo = ''
        content_type = ''

    if photo and save_as:
        extension = content_type.split('/')[1]
        filename = save_as + '.' + extension
        with open(filename, 'wb') as fhandle:
            fhandle.write(photo)
    else:
        filename = ''

    return (photo, photo_status_code, content_type, filename)

替代方法，基于原始问题的代码，如果您想在网页上显示生成的图像。

from base64 import b64encode

@app.route("/photo")
def get_photo():
    token = _get_token_from_cache(app_config.SCOPE)
    if not token:
        return redirect(url_for("login"))
    response = requests.get(
        app_config.PHOTO_ENDPOINT,  
        headers={'Authorization': 'Bearer ' + token['access_token']}
    )
    content_type = response.raw.getheader('Content-Type')
    return render_template('index.html',
                           photo_data=b64encode(response.content),
                           photo_content_type=content_type)

然后在 index.html 模板中，您可以像这样显示照片：

<html>
  <body>
    <img src="data:{{ photo_content_type }};base64,{{ photo_data }}" />
  </body>
</html>
