使用 .NET 客户端库为 VSTS/TFS 检索构建定义的任务列表

Question

我正在使用 VSTS/TFS (https://docs.microsoft.com/en-us/vsts/integrate/concepts/dotnet-client-libraries?view=vsts) 的 .NET 客户端库来检索所有团队项目的所有构建定义的任务列表。我正在使用 NuGet 包 Microsoft.TeamFoundation.ExtendedClient 的 v16.139.0-preview 版本（我需要这样做，因为我还需要检索发布定义工作流，您需要 Microsoft.VisualStudio.Services.Release.Client ，它有一个ExtendedClient 的依赖项要求）。服务器（本地）是 TFS 2017.2。我无论如何都无法检索任务/阶段/过程。这是我的代码：

VssConnection connection = new VssConnection(new Uri("http://tfsserver:8080/tfs/defaultcollection"), new VssClientCredentials());
ProjectHttpClient projectClient = connection.GetClient<ProjectHttpClient>();
IEnumerable<TeamProjectReference> projects = projectClient.GetProjects().Result;
BuildHttpClient buildClient = connection.GetClient<BuildHttpClient>();
foreach (var project in projects)
{
  IPagedList<BuildDefinition> buildDefinitions = buildClient.GetFullDefinitionsAsync2(project: project.Name, name: null).Result;
  foreach (BuildDefinition buildDefinition in buildDefinitions)
  {
    // get the tasks
  }
}

• 我尝试使用 buildClient.GetDefinitionAsync 重新检索构建定义，但没有其他效果
• “Steps”属性（将被弃用）始终为 null
• “进程”属性为空
• 没有可用的“阶段”属性（从构建定义中具有多个阶段的选项来看似乎合乎逻辑
• BuildDefinitionStep 有一个可用的合同：https://docs.microsoft.com/en-us/vsts/extend/reference/client/api/tfs/build/contracts/builddefinitionstep?view=vsts
• REST API 文档没有名为“Step”的属性：https://docs.microsoft.com/en-us/rest/api/vsts/build/definitions/get?view=vsts-rest-4.1#builddefinition

有人知道如何解决这个问题吗？

聚会有点晚了，但如果您想使用 AzDO .NET 客户端库迭代构建任务，您需要将流程转换为 DesignerProcess/DockerProcess/YamlProcess。

var buildDefinitions = await _buildClient.GetFullDefinitionsAsync(project.Id);
foreach (var buildDefinition in buildDefinitions)
{
    if (buildDefinition.Process != null && buildDefinition.Process is Microsoft.TeamFoundation.Build.WebApi.DesignerProcess designerProcess)
    {
        foreach (var phase in designerProcess.Phases)
            foreach (var step in phase.Steps)
                Console.WriteLine($"taskname={step.DisplayName}");
        break;//lets exit the loop early
    }
}

只需使用 .NET 客户端库尝试以下 C# 示例，在 TFS 2017.3 和 VSTS 上进行测试，两者都可以。 （我这边没有 TFS 2017.2，如果我没记错的话，TFS 2017.2 的构建过程与 TFS 2015 类似，它没有“Process”和“phases”属性。）

using System;
using Microsoft.TeamFoundation.Build.WebApi;
using Microsoft.VisualStudio.Services.Client;
using Microsoft.VisualStudio.Services.Common;

namespace RetrieveTaskList
{
    class Program
    {
        static void Main(string[] args)
        {
            //For TFS :
            var tfsUrl = "http://ws-tfs2017:8080/tfs/DefaultCollection";
            var buildClient = new BuildHttpClient(new Uri(tfsUrl), new VssAadCredential());

            //For VSTS:
            //var tfsUrl = "https://{account}.visualstudio.com";
            //var buildClient = new BuildHttpClient(new Uri(tfsUrl), new VssBasicCredential(string.Empty, "PAT here"));

            var definitions = buildClient.GetFullDefinitionsAsync(project: "ScrumProject");

            foreach (var definition in definitions.Result)
            {
                Console.WriteLine(string.Format("\n {0} - {1}:", definition.Id, definition.Name));

                // Get BuildDefinitionStep to array, each of which has a task property that contains things like the name of the task and the inputs.
                var tasks = definition.Steps.ToArray();

                //Get each step/task from the array
                foreach (var task in tasks)
                {
                    Console.WriteLine(task.DisplayName);
                }
            }
            Console.ReadLine();
        }
    }
}

您还可以使用REST API 从构建定义中检索任务列表。

以PowerShell为例：

Param(
   [string]$baseurl = "http://server:8080/tfs/DefaultCollection", 
   [string]$projectName = "ProjectName",
   [string]$buildDefinitionID = "26",
   [string]$user = "domain\user",
   [string]$token = "password"
)

# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))


$uri = "$baseurl/$($projectName)/_apis/build/definitions/$buildDefinitionID"
Write-Host $uri
$result = (Invoke-RestMethod -Uri $uri -Method Get -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)})
$tasks = $result.process.phases.steps.displayName

foreach ($task in $tasks)
{
  write-host $task
}

你也可以试试 REST Client，请参考这个帖子：Retrieve VSTS/TFS Build task name list

在@Andy 的帮助下，我能够解决问题。我使用 Fiddler 调用 REST Api (http://server:8080/tfs/DefaultCollection/MyProject/_apis/build/definitions/1) 并读取 JSON 响应。我发现“构建”属性包含任务集合。我修复了@Andy 提供的 PowerShell 脚本：

Param(
   [string]$baseurl = "http://server:8080/tfs/DefaultCollection", 
   [string]$projectName = "MyProject",
   [string]$buildDefinitionID = "530",
   [string]$user = "domain\user",
   [string]$token = "PersonalAccessToken"
)

# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))

$uri = "$baseurl/$($projectName)/_apis/build/definitions/$buildDefinitionID"
Write-Host $uri
$result = (Invoke-RestMethod -Uri $uri -Method Get -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)})

foreach ($task in $result.build)
{
    Write-Host $task.displayName
}
