問(wèn)題描述

我在 Microsoft Graph Api 代碼下運(yùn)行:

I am running below Microsoft Graph Api code:

using Microsoft.IdentityModel.Clients.ActiveDirectory;
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

namespace AADConsole2
{
    class Program
    {

        private const string aadInstance = "https://login.microsoftonline.com/{0}";
        //  private const string ResourceUrl = "https://graph.windows.net";

        private const string resource = "https://graph.microsoft.com";
        private const string GraphServiceObjectId = "XXX";
        private const string TenantId = "XXX";
        private const string tenant = "XXXX.onmicrosoft.com";
        private const string ClientId = "XXX";
        private static string appKey= "XXXX";
        static string authority = String.Format(System.Globalization.CultureInfo.InvariantCulture, aadInstance, tenant);

        private static HttpClient httpclient = new HttpClient();
        private static AuthenticationContext context = null;
        private static ClientCredential credential = null;


        static void Main(string[] args)
        {

            context = new AuthenticationContext(authority);
            credential = new ClientCredential(ClientId, appKey);
            Task<string> token = GetToken();
            token.Wait();
            Console.WriteLine(token.Result);
            Task<string> users = GetUsers(token.Result);
            users.Wait();
            Console.WriteLine(users.Result);
            Console.ReadLine();
        }

        private static async Task<string> GetUsers(string result) {
            //throw new NotImplementedException();
            string users = null;
            var uri = "https://graph.microsoft.com/v1.0/users";
            httpclient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", result);
            var getResult = await httpclient.GetAsync(uri);

            if(getResult.Content != null)
            {
                users = await getResult.Content.ReadAsStringAsync();

            }
            return users;

        }


        private static async Task<string> GetToken()
        {
            AuthenticationResult result = null;
            string token = null;
            result = await context.AcquireTokenAsync(resource, credential);
            token = result.AccessToken;
            return token;



        }
    }
}

我在控制臺(tái)上打印了用戶(hù)詳細(xì)信息的結(jié)果，但只打印了有限數(shù)量的用戶(hù).即只有其名稱(chēng)以字母a"開(kāi)頭.并且還缺少一些用戶(hù)詳細(xì)信息.如何獲取所有用戶(hù)詳細(xì)信息.我在這段代碼中缺少一些 api 嗎?謝謝.

I am getting the results of user detail printed on console ,but only limited number of users are printed. i.e only whose name starts with letter 'a'. And also some user details are missing. How to get all user details .Am i missing some api in this code? Thanks.

大多數(shù) Microsoft Graph 端點(diǎn)返回分頁(yè)結(jié)果集.您的初始請(qǐng)求僅返回第一頁(yè)數(shù)據(jù).要檢索下一頁(yè)，請(qǐng)遵循 @odata.nextLink 屬性中提供的 URI.每個(gè)后續(xù)頁(yè)面將返回下一頁(yè)的 @odata.nextLink 直到您的最后一頁(yè)數(shù)據(jù)(由結(jié)果中缺少 @odata.nextLink 表示).在 在您的應(yīng)用中分頁(yè) Microsoft Graph 數(shù)據(jù).

Most Microsoft Graph endpoints return paged result sets. Your initial request only returns the first page of data. To retrieve the next page, you follow the URI provided in the @odata.nextLink property. Each subsequent page will return the next page's @odata.nextLink until you the last page of data (denoted by the lack of a @odata.nextLink in the result). There is a step-by-step walkthrough of how this works at Paging Microsoft Graph data in your app.

我可以在這里給你的最重要的一條提示是不要使用 $top 來(lái)強(qiáng)制它返回大頁(yè)數(shù)據(jù).這是一種調(diào)用 API 效率極低的方法，不可避免地會(huì)導(dǎo)致網(wǎng)絡(luò)錯(cuò)誤和請(qǐng)求限制.它也沒(méi)有消除處理分頁(yè)的需要，因?yàn)榧词?$top=999(最大值)仍然可以返回多個(gè)頁(yè)面.

The single most important tip I can give you here is to not use $top to force it to return large pages of data. This is an extremely inefficient method for calling the API and inevitably leads to network errors and request throttling. It also doesn't eliminate the need to handle paging since even $top=999 (the maximum) can still return multiple pages.

實(shí)現(xiàn)分頁(yè)，保持頁(yè)面較小，并在返回每個(gè)頁(yè)面后處理結(jié)果，然后再轉(zhuǎn)到下一頁(yè).這將確保您捕獲所有數(shù)據(jù)并允許您的應(yīng)用程序在處理過(guò)程中遇到任何錯(cuò)誤時(shí)從中斷的地方繼續(xù).

Implement paging, keep your page sizes small, and process the results after each page is returned before moving on to the next page. This will ensure you capture all of the data and allow your application to pick up where it left off should it encounter any errors during processing.

這篇關(guān)于C# 中的 Microsoft Graph api 代碼僅顯示有限數(shù)量的用戶(hù)的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
