Powershell：使用 REST API 从 Sharepoint 列表中删除项目 - 远程服务器返回错误：(400) 错误请求

Question

我的问题是在 Sharepoint 2013 年到 2019 年的迁移之后。 我们必须从列表中删除项目的脚本已停止工作。 我可以很好地获取列表中所有项目的 id，但第一次删除会返回 400 错误。 我注意到 REST API URL 发生了变化，我做了这些，但不确定我在这里遗漏了什么。 下面的代码片段。

Answer 1

我确实相信您的 Post uri 格式错误。 items和Guid没有分离，这看起来有点奇怪。

POST http://sites.example.com/teams/Cloud_Enablement_Program/_api/web/lists/GetByTitle('AWS Idaptive Accounts')/items5b0ec0be-7238-45ef-b7db-032accbb2677

看起来它需要为($ItemId) 包含括号

https://{site_url}/_api/web/lists/getbytitle('Documents')/items({item_id})
