Net 呼叫 Graph API 的小栗子

　　前言

　　最近，有小夥伴在做Net開發，碰到了呼叫Graph Net API的情況，在認證的時候碰到了問題，幫忙解決問題之餘，也分享給大家，希望能對遇到一樣問題的朋友有所幫助。

　　正文

　　程式碼比較簡單了，就是用過一個Azure App去做認證，引數就是三個，返回的GraphServiceClient物件就可以直接使用了

public GraphServiceClient CreateGraphServiceClient(string tenantId, string clientId, string clientSecret)
{
    try
    {
        var scopes = new[] { "https://graph.microsoft.com/.default" };
        var options = new TokenCredentialOptions
        {
            AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
        };

        var clientSecretCredential = new ClientSecretCredential(
            tenantId, clientId, clientSecret, options);

        GraphClient = new GraphServiceClient(clientSecretCredential, scopes);
        return GraphClient;
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message.ToString());
        Console.WriteLine(ex.StackTrace);
        return null;
    }
}

　　呼叫就更簡單了，先新建一個GraphServiceClient物件，然後物件會帶著你做接下來的事情了

// Create GraphServiceClient Object
GraphServiceClient graphClient = CreateGraphServiceClient("tenantId", "clientId", "clientSecret")

// Code snippets are only available for the latest version. Current version is 5.x

// Dependencies
using Microsoft.Graph.Models;

var requestBody = new User
{
    BusinessPhones = new List<string>
    {
        "+1 425 555 0109",
    },
    OfficeLocation = "Huaguo Mountain, Water Curtain Cave",
};

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
var result = await graphClient.Users["{user-id}"].PatchAsync(requestBody);

　　結束語

　　程式碼就是這樣，寫過一遍就會覺得非常簡單，其實也灰常簡單。

　　程式碼片段來自官網，可能會跟隨Graph API的版本變化而改變(其實蠻坑的)，具體程式碼可以參考官網 Update user - Microsoft Graph v1.0 | Microsoft Learn
