SharePoint REST API 联机批处理请求问题：收到 400 错误请求，odata.error 无效请求

Question

我在使用 _api/$batch 请求隔离批处理请求时遇到了一些问题。我确定只有一些简单的 mistake/issue 正在发生，但我无法确定这一点。有什么想法吗？

以下是请求的原始邮递员控制台日志的一些片段：

POST /_api/$batch HTTP/1.1
Accept: application/json; odata=nometadata
Content-Type: multipart/mixed; boundary="batch_8215457c-c4fb-432a-abf6-7b1f86168c65"
Authorization: Bearer <token deleted>

我对每个要删除的项目返回的响应是 400 Bad Request，每个 Batch 响应还包含： {"odata.error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-US","value":"无效请求。"} }}

--batchresponse_38add954-a201-4857-a6db-68067eb9bc0a
Content-Type: application/http
Content-Transfer-Encoding: binary

HTTP/1.1 400 Bad Request
CONTENT-TYPE: application/json;odata=nometadata;streaming=true;charset=utf-8

{"odata.error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-US","value":"Invalid request."}}}
--batchresponse_38add954-a201-4857-a6db-68067eb9bc0a
Content-Type: application/http
Content-Transfer-Encoding: binary

HTTP/1.1 400 Bad Request
CONTENT-TYPE: application/json;odata=nometadata;streaming=true;charset=utf-8

{"odata.error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-US","value":"Invalid request."}}}
--batchresponse_38add954-a201-4857-a6db-68067eb9bc0a--

我一直在挖掘并尝试了一些东西：

• 尝试从每个变更集中删除“接受：application/json；odata=nometadata”
• 尝试在请求后调整任何换行符content-type/encoding
• 我尝试将批处理中的一个项目作为单个删除请求执行（有效）
• 比较了一些 notes/examples：（Andrew Connell 博客：https://gist.github.com/andrewconnell/dcd89e694475b628d0c7）

有大神能指出错误吗？

Answer 1

这是我对文档的错误解释。

根据 Microsoft's documentation，请求 URL 部分指出（强调我的）：

The request URL consists of the root service URL and the $batch option; for example, https://fabrikam.sharepoint.com/_api/$batch or https://fabrikam.office365.com/api/v1.0/me/$batch.

但是，“根服务 URL”有点误导，因为它实际上应该是 站点的 URL。我会考虑根服务 URL:

https://myorg.sharepoint.com

因此，在我上面的示例中，它是：

POST <siteURL>/_api/$batch  

或者，更具体的示例：

POST https://yourorg.sharepoint.com/sites/mySite  HTTP/1.1

感谢所有对此进行思考的人。
