Layanan Azure DevOps | Azure DevOps Server 2022 - Azure DevOps Server 2019

Sampel berikut menunjukkan cara memperluas dan mengintegrasikan dengan Azure DevOps menggunakan pustaka klien .NET.

Sampel di GitHub

Pada halaman GitHub Sampel .NET, Anda dapat menemukan banyak sampel dengan instruksi tentang cara menjalankannya.

Contoh REST di halaman ini memerlukan paket NuGet berikut:

Contoh: Menggunakan klien HTTP berbasis REST

// https://www.nuget.org/packages/Microsoft.TeamFoundationServer.Client/
using Microsoft.TeamFoundation.WorkItemTracking.WebApi;
using Microsoft.TeamFoundation.WorkItemTracking.WebApi.Models;

// https://www.nuget.org/packages/Microsoft.VisualStudio.Services.InteractiveClient/
using Microsoft.VisualStudio.Services.Client;

// https://www.nuget.org/packages/Microsoft.VisualStudio.Services.Client/
using Microsoft.VisualStudio.Services.Common; 

/// <summary>
/// This sample creates a new work item query for New Bugs, stores it under 'MyQueries', runs the query, and then sends the results to the console.
/// </summary>
public static void SampleREST()
{
    // Connection object could be created once per application and we use it to get httpclient objects. 
    // Httpclients have been reused between callers and threads.
    // Their lifetime has been managed by connection (we don't have to dispose them).
    // This is more robust then newing up httpclient objects directly.  
    
    // Be sure to send in the full collection uri, i.e. http://myserver:8080/tfs/defaultcollection
    // We are using default VssCredentials which uses NTLM against an Azure DevOps Server.  See additional provided
    // Create a connection with PAT for authentication
    VssConnection connection = new VssConnection(orgUrl, new VssBasicCredential(string.Empty, personalAccessToken));


    // Create instance of WorkItemTrackingHttpClient using VssConnection
    WorkItemTrackingHttpClient witClient = connection.GetClient<WorkItemTrackingHttpClient>();

    // Get 2 levels of query hierarchy items
    List<QueryHierarchyItem> queryHierarchyItems = witClient.GetQueriesAsync(teamProjectName, depth: 2).Result;

    // Search for 'My Queries' folder
    QueryHierarchyItem myQueriesFolder = queryHierarchyItems.FirstOrDefault(qhi => qhi.Name.Equals("My Queries"));
    if (myQueriesFolder != null)
    {
        string queryName = "REST Sample";

        // See if our 'REST Sample' query already exists under 'My Queries' folder.
        QueryHierarchyItem newBugsQuery = null;
        if (myQueriesFolder.Children != null)
        {
            newBugsQuery = myQueriesFolder.Children.FirstOrDefault(qhi => qhi.Name.Equals(queryName));
        }
        if (newBugsQuery == null)
        {
            // if the 'REST Sample' query does not exist, create it.
            newBugsQuery = new QueryHierarchyItem()
            {
                Name = queryName,
                Wiql = "SELECT [System.Id],[System.WorkItemType],[System.Title],[System.AssignedTo],[System.State],[System.Tags] FROM WorkItems WHERE [System.TeamProject] = @project AND [System.WorkItemType] = 'Bug' AND [System.State] = 'New'",
                IsFolder = false
            };
            newBugsQuery = witClient.CreateQueryAsync(newBugsQuery, teamProjectName, myQueriesFolder.Name).Result;
        }

        // run the 'REST Sample' query
        WorkItemQueryResult result = witClient.QueryByIdAsync(newBugsQuery.Id).Result;

        if (result.WorkItems.Any())
        {
            int skip = 0;
            const int batchSize = 100;
            IEnumerable<WorkItemReference> workItemRefs;
            do
            {
                workItemRefs = result.WorkItems.Skip(skip).Take(batchSize);

Autentikasi

Untuk mengubah metode autentikasi untuk Azure DevOps, ubah jenis VssCredential yang diteruskan ke Vss Koneksi ion saat Anda membuatnya.

Autentikasi token akses pribadi untuk layanan REST
public static void PersonalAccessTokenRestSample()
{
    // Create instance of VssConnection using Personal Access Token
    VssConnection connection = new VssConnection(orgUrl, new VssBasicCredential(string.Empty, personalAccessToken));
}

Permintaan masuk Visual Studio (Akun Microsoft atau backend Microsoft Entra) untuk layanan REST (hanya.NET Framework)

Karena versi .NET Core tidak mendukung dialog interaktif, sampel ini hanya berlaku untuk versi .NET Framework klien.

public static void MicrosoftAccountRestSample()
{
    // Create instance of VssConnection using Visual Studio sign-in prompt
    VssConnection connection = new VssConnection(new Uri(collectionUri), new VssClientCredentials());
}

Autentikasi Microsoft Entra untuk layanan REST
public static void AADRestSample()
{
    // Create instance of VssConnection using Azure AD Credentials for Azure AD backed account
    VssConnection connection = new VssConnection(new Uri(collectionUri), new VssAadCredential(userName, password));
}
Autentikasi OAuth untuk layanan REST

Untuk informasi selengkapnya, lihat Sampel autentikasi Azure DevOps.

public static void OAuthSample()
{
    // Create instance of VssConnection using OAuth Access token
    VssConnection connection = new VssConnection(new Uri(collectionUri), new VssOAuthAccessTokenCredential(accessToken));
}
