Linkedin 图片/视频 API 上传 403 禁止错误

我正在调用 linkedin 图像 API 来初始化上传。我正在使用 insomnia 来拨打电话，我拥有未过期的访问令牌（4 天前创建）以及以下所有权限/范围 ( r_1st_connections_size,r_ads,r_ads_reporting,r_basicprofile,r_organization_admin,r_organization_social,rw_ads,rw_organization_admin,w_member_social,w_organization_social )。以下是在 python 中导出的调用代码。我拥有所有正确的权限，并且 linkedin 帐户是活动经理，但每次我不断收到下面包含的 403 禁止错误。

输入/调用：

import requests

url = "https://api.linkedin.com/rest/images"

querystring = {"action":"initializeUpload"}

payload = {"initializeUploadRequest": {

        }
    }}

response = requests.request("POST", url, json=payload, headers=headers, params=querystring)

print(response.text)

我尝试制作一个新的访问令牌，使用 MediaLibraryMetadata ，我尝试使用视频 api 并遇到同样的问题。我期待一个带有 uploadUrl 的 200 OK 状态代码来上传图像，以及类似以下响应示例的内容。

{
   "value": {
       "uploadUrlExpiresAt": 1650567510704,
       "uploadUrl": "https://www.linkedin.com/dms-uploads/C4E10AQFoyyAjHPMQuQ/uploaded-image/0?ca=vector_ads&cn=uploads&sync=0&v=beta&ut=08zHQjMjAOLqc1",
       "image": "urn:li:image:C4E10AQFoyyAjHPMQuQ"
   }
}

收到 403 禁止错误的原因是尝试将图片上传到赞助帐户的媒体库。目前，Linkedin API 不支持此功能。

虽然可以使用 Images API 和 Videos API 将图片和视频上传到 个人 Linkedin 帐户，但 无法 直接将媒体上传到赞助帐户。

可以在此处找到 Linkedin 的官方文档中提到的此限制： https://learn.microsoft.com/en-us/linkedin/marketing/integrations/ads/asset-management/media-library?tabs=http#known-issues

可能的解决方法：

1. 使用 Linkedin Campaign Manager UI： 要将图片上传到的赞助帐户，请继续使用 Linkedin Campaign Manager 界面。这是上传媒体到赞助帐户的推荐方法。

2. 创建单独的 API 请求以获取资产： 上传图片后，可以使用 Images API 或 Videos API 使用其相应的 URN 检索其详细信息。

请记住，Linkedin 的 API 及其功能可能会发生变化。始终建议查阅其官方文档以获取最新信息和更新。
