Net 调用 Graph API 的小栗子

　　前言

　　最近，有小伙伴在做Net开发，碰到了调用Graph Net API的情况，在认证的时候碰到了问题，帮忙解决问题之余，也分享给大家，希望能对遇到一样问题的朋友有所帮助。

　　正文

　　代码比较简单了，就是用过一个Azure App去做认证，参数就是三个，返回的GraphServiceClient对象就可以直接使用了

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;
    }
}

　　调用就更简单了，先新建一个GraphServiceClient对象，然后对象会带着你做接下来的事情了

// 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);

　　结束语

　　代码就是这样，写过一遍就会觉得非常简单，其实也灰常简单。

　　代码片段来自官网，可能会跟随Graph API的版本变化而改变(其实蛮坑的)，具体代码可以参考官网 Update user - Microsoft Graph v1.0 | Microsoft Learn
