linkedin - 无法通过 API 发布到 LinkedIn 群组

Question

按照此处的“创建群组帖子”示例通过 LinkedIn API 发布到群组时:
https://docs.microsoft.com/en-us/linkedin/compliance/integrations/groups/group-posts-and-actions?context=linkedin/compliance/context
我总是收到:
“REQUEST_BODY 中存在不允许的字段:处理字段 [/containerEntity] 时出现数据处理异常”
我们的应用程序是营销开发者平台合作伙伴。我在授权时获得了 w_organization_social、w_member_social、rw_organization_admin、r_liteprofile、r_emailaddress 权限。
我可以成功发布到组织页面。
我该如何解决这个错误？我们需要请求额外的权限吗？

Answer 1

我正在查看您链接中的示例代码:

{
    "author": "urn:li:person:123ABC", 
    "containerEntity": "urn:li:group:123", 
    "lifecycleState": "PUBLISHED", 
    "specificContent": {
        "com.linkedin.ugc.ShareContent": {
            "media": [
                {
                    "description": {
                        "attributes": [], 
                        "text": "Check out our awesome group!"
                    }, 
                    "status": "READY", 
                    "thumbnails": [], 
                    "title": {
                        "attributes": [], 
                        "text": "Group Post!"
                    }
                }
            ], 
            "shareCommentary": {
                "attributes": [], 
                "text": "Some group text"
            }
        }
    }, 
    "visibility": {
        "com.linkedin.ugc.MemberNetworkVisibility": "CONTAINER"
    }
}

我注意到在示例代码中，它是 media:[ ]
但是在你的代码中你没有使用 []
这可能就是您收到此错误消息的原因。
