从Outlook Office REST API获取联系人计数-Javascript [英] Getting a Count of Contacts from Outlook Office REST API - Javascript
问题描述
我很难区分Microsoft数量众多的冲突API文档:outlook.office.com，outlook.office365.com，microsoft graph，Azure等
I'm having difficulty distinguishing between Microsoft's absurd amount of conflicting API documentations: outlook.office.com, outlook.office365.com, microsoft graph, Azure, and so on
我已经成功验证并拉出了联系人，但是似乎无法计数何时停止分页.
I've successfully authenticated and pulled contacts, but I can't seem to get a count to know when I should stop pagination.
我一直在使用:
Access Token url:
https://login.microsoftonline.com/common/oauth2/v2.0/token;
Successful Contact url:
https://outlook.office.com/api/v2.0/me/contacts;
他们的 REST API资源说，我应该能够简单地调用https://outlook.office.com/api/v2.0/me/contacts/$count，但这将始终返回正文为-1的纯文本MIME类型.
Their REST API Resource says I should be able to simply make a call to https://outlook.office.com/api/v2.0/me/contacts/$count but this keeps returning a plaintext MIME type with body -1.
如果有人以前曾为此苦苦挣扎或知道发生了什么，我将向正确的方向表示感谢，并希望为您提供一些简单的建议！
If anyone has struggled with this before or knows what's going on, I'd appreciate a point in the right direction - and hopefully some easy points for you!

第二次编辑:即使返回了有效的联系人数组，看起来https://outlook.office.com/api/v2.0/me/contacts?$count=true也会返回@odata.count": -1.
2nd Edit: It looks like https://outlook.office.com/api/v2.0/me/contacts?$count=true returns @odata.count": -1 as well, even as it returns valid array of contacts.

推荐答案
很抱歉得知您遇到了麻烦！这里发生了几件事.
Sorry to hear that you're having trouble! There's a couple of things going on here.
令人困扰的是，您从$count通话中获得了一个负数.如果您访问 https://oauthplay.azurewebsites.net 并使用您的帐户登录，是否会得到相同的结果从那个电话吗?
It's troubling that you're getting a negative number back from the $count call. If you go to https://oauthplay.azurewebsites.net and login with your account, do you get the same result from that call?
对于分页，如果您只想获取所有结果，则最好不要依赖$count值.相反，您应该使用响应中返回的@odata.nextLink值来获取下一页.当然，如果要在获得所有结果之前尝试向用户指示有多少页，那么$count是做到这一点的方法.
For paging, if all you want to do is get all the results, it is better to not rely on the $count value. Instead, you should use the @odata.nextLink value that comes back in the response to get the next page. Of course if you're trying to indicate to a user how many pages are there before getting all the results, the $count is the way to do that.
分页由页面大小($top参数)和光标"($skip parameter). If you're making a call to/me/contacts with no parameters, then you're getting the default page size of 10 and default cursor of 0. You can use the $ top`参数)控制，以请求每页更多结果.
Paging is controlled by the page size (the $top parameter) and the "cursor" (the $skip parameter). If you're making a call to/me/contactswith no parameters, then you're getting the default page size of 10 and default cursor of 0. You can use the$top` parameter to request more results per page.
@odata.nextLink值将始终返回一个URL，您可以根据您在$top中指定的页面大小(如果未指定，则为10)来获取下一页.这是执行GET https://outlook.office.com/api/v2.0/me/contacts的值:
The @odata.nextLink value will always return a URL you can use to get the next page based on the page size you specified in $top (or 10 if you did not specify). Here's the value from doing GET https://outlook.office.com/api/v2.0/me/contacts:
"@odata.nextLink": "https://outlook.office.com/api/v2.0/me/contacts/?%24skip=10"
这会跳过10个结果(基于默认的页面大小10).
This skips you ahead 10 results (based on the default page size of 10).
这是GET https://outlook.office.com/api/v2.0/me/contacts/?$top=20中的值:
"@odata.nextLink": "https://outlook.office.com/api/v2.0/me/contacts/?%24top=20&%24skip=20"
如果没有更多页面，则@odata.nextLink值将不会出现在响应中.因此，您可以将其用作停止分页的指示器.
If there are no more pages, the @odata.nextLink value will not be present in the response. So you can use that as your indicator to stop paging.
