尝试在 sharepoint 365 中计算 $batch REST api
我的请求负载（简单的 GET 请求）
--batch_45993c25-30ce-459d-830f-a5aabaf4901f
Content-Type: application/http
Content-Transfer-Encoding: binary
GET https://${tenant}.sharepoint.com/test/_api/Web/Lists/GetByTitle('List')/Items?$orderby=Title HTTP/1.1
Accept: application/json;odata=verbose
--batch_45993c25-30ce-459d-830f-a5aabaf4901f--
创建一个项目并将其取回
--batch_28fcce05-10f9-4362-e7fb-55208b1ec9d8
Content-Type: multipart/mixed; boundary=changeset_eabea18e-488d-46fc-ba25-841d268c61c4
Content-Length: 406
Content-Transfer-Encoding: binary
--changeset_eabea18e-488d-46fc-ba25-841d268c61c4
Content-Type: application/http
Content-Transfer-Encoding: binary
POST https://${tenant}.sharepoint.com/test/_api/Web/Lists/GetByTitle('List')/Items HTTP/1.1
Content-Type: application/json;odata=verbose
{"Title":"2","Message":"2","__metadata":{"type":"SP.Data.ListListItem"}}
--changeset_eabea18e-488d-46fc-ba25-841d268c61c4--
--batch_28fcce05-10f9-4362-e7fb-55208b1ec9d8
Content-Type: application/http
Content-Transfer-Encoding: binary
GET https://${tenant}.sharepoint.com/test/_api/Web/Lists/GetByTitle('List')/Items?$orderby=Title HTTP/1.1
Accept: application/json;odata=verbose
--batch_28fcce05-10f9-4362-e7fb-55208b1ec9d8--
我得到的回应是针对他们俩的。
{"error":
{"code":"-1, Microsoft.Data.OData.ODataContentTypeException",
"message":
{"lang":"en-US",
"value":"A supported MIME type could not be found that matches the content type of the response. None of the supported type(s) 'multipart/mixed' matches the content type 'application/json;odata=verbose'."
}
}
}
该请求与文档完全相同，但仍然没有运气：
https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/make-batch-requests-with-the-rest-apis
有人可以帮忙吗？
更新：添加代码
