使用Microsoft OneDrive API/SDK的客户端分页 [英] Client side paging using Microsoft OneDrive API/SDK

问题描述

我正在尝试使用Microsoft OneDrive API/SDK实现客户端分页.为此，我需要将商品总数作为API的响应，并基于传递给API的跳过和最大限制值来获取响应.

I am trying to implement client side paging using Microsoft OneDrive API/SDK. For that I need the total count of items as response from the API, and based on the skip and maximum limit value passed to the API, the response should be fetched.

在列表项链接，提到我们可以使用此处.基于此假设，我正在如下构建API调用的URL:

In the List Items link, it is mentioned that we can achieve this using the query strings provided here. Based on this assumption, I am building the URL for API call as below:

string.Format("https://graph.microsoft.com/v1.0/me/drive/root/children?$skip={0}&$top={1}&$count=true",topValue*page, topValue)

根据上述URL中的信息，一切似乎都很好，但是我从服务器收到错误请求"，并显示错误消息，如下所示:

Everything seems to be fine as per the info in the above mentioned URL, but I am getting "Bad Request" from the server with error message as shown below:

{
  "error": {
    "code": "",
    "message": "The query specified in the URI is not valid. Query option 'Skip' is not allowed. To allow it, set the 'AllowedQueryOptions' property on EnableQueryAttribute or QueryValidationSettings.",
    "innerError": {
      "request-id": "384693d7-65bd-4dc6-8d60-afde68e01555",
      "date": "2017-04-25T10:28:15"
    }
  }
}


{
  "error": {
    "code": "",
    "message": "The query specified in the URI is not valid. Query option 'Count' is not allowed. To allow it, set the 'AllowedQueryOptions' property on EnableQueryAttribute or QueryValidationSettings.",
    "innerError": {
      "request-id": "2188a06f-10cf-402c-9c49-bd296b9db614",
      "date": "2017-04-25T10:29:05"
    }
  }
}

可以使用REST API或Microsoft Graph SDK来实现吗?

Can this be achieved using REST APIs or Microsoft Graph SDK?

PS:我看到了skipToken的概念，但是它不符合我们的要求，因为它不返回总数，并且仅支持增量导航.

PS: I saw the concept of skipToken but that won't fit into our requirements as it does not return the total count and only incremental navigation is supported.

推荐答案

似乎OneDrive工程师已经回答了这个问题

It appears that a OneDrive engineer has already answered this question here:

OneDrive的分页模型与skip + take有点不同. 本质上，您将进行如下查询:

OneDrive's paging model is a little different to skip+take. Essentially you'll make a query like:

获取 https://graph.microsoft.com/v1. 0/me/drive/root/children ?$ top = 5

GET https://graph.microsoft.com/v1.0/me/drive/root/children?$top=5

，在响应中，您将看到通常的值数组，以及 具有名为@ odata.nextLink的属性.您需要使用该URL 使用它请求下一页:

and in the response you should see the usual array of values, along with a property called @odata.nextLink. You'll want to take that URL use it request the next page:

"@ odata.nextLink": " https://graph.microsoft.com/v1.0/me /drive/root/children ?$ skiptoken = ASDGASGSD"

"@odata.nextLink": "https://graph.microsoft.com/v1.0/me/drive/root/children?$skiptoken=ASDGASGSD"

获取 https://graph.microsoft.com/v1.0/me/驱动器/根目录/孩子?$ skiptoken = ASDGASGSD

GET https://graph.microsoft.com/v1.0/me/drive/root/children?$skiptoken=ASDGASGSD

您一直这样做，直到没有返回@ odata.nextLink.

You keep doing this until you don't get an @odata.nextLink returned.
