到 GIT 的 C# 连接失败

Question

我有一个生成文件的应用程序需要存储在 ADO 的 GIT 存储库中。我正在尝试连接到存储库，但它无法给我一个 GIT 客户端。这是我的初始测试控制台应用程序（基于 https://docs.microsoft.com/en-us/azure/devops/integrate/concepts/dotnet-client-libraries?view=azure-devops）

using System;
using Microsoft.TeamFoundation.SourceControl.WebApi;
using Microsoft.VisualStudio.Services.Common;
using Microsoft.VisualStudio.Services.WebApi;

namespace AdoInteractionSandbox
{
    class Program
    {
        const string projectName = "MyGreatProject";
        const string repoName = "MyRepo";

        static void Main(string[] args)
        {
            SimpleConnectionTest();

            Console.WriteLine("Finished. Hit return to continue.");
            Console.Read();
        }

        private static void SimpleConnectionTest()
        {
            string[] connectionURIs = new string[] {
                "https://dev.azure.com/myCompany",
                "https://dev.azure.com/myCompany/REPOS",
                "https://dev.azure.com/myCompany/REPOS/_git",
                "https://dev.azure.com/myCompany/REPOS/_git/MyFiles"
            };

            var creds = new VssBasicCredential(); // using default credentials for the user

            foreach (string uri in connectionURIs)
            {
                try
                {
                    Console.WriteLine($"Connecting to Azure DevOps Services at {uri}");
                    var connection = new VssConnection(new Uri(uri), creds);

                    Console.WriteLine($"Getting a GitHttpClient to talk to the Git endpoints");
                    var gitClient = connection.GetClient<GitHttpClient>();

                    Console.WriteLine($"Getting data about a specific repository");
                    var repo = gitClient.GetRepositoryAsync(projectName, repoName).Result;
                }
                catch (Exception ex)
                {
                    Console.WriteLine($"{uri} : {ex.Message}");
                    Console.WriteLine();
                }
            }

        }
    }
}

所以我尝试了各种 URI，所有这些都在 Edge 中的某个地方，但是 none 给了我一个 gitClient。这是输出：

Connecting to Azure DevOps Services at https://dev.azure.com/myCompany
Getting a GitHttpClient to talk to the Git endpoints
https://dev.azure.com/myCompany : VS30063: You are not authorized to access https://dev.azure.com.

Connecting to Azure DevOps Services at https://dev.azure.com/myCompany/REPOS

Getting a GitHttpClient to talk to the Git endpoints
https://dev.azure.com/myCompany/REPOS/_git/MyFiles : Page not found.

Finished. Hit return to continue.

那么我应该使用什么作为 URI？还是有其他问题，可能与我获得的凭据有关？

Answer 1

您提到的页面明确指出，当代码中未提供凭据时，应显示一个询问凭据的交互式对话框。但是，如果您的控制台应用程序使用 .NET Standard，则不会显示该对话框。在这种情况下，您需要在身份验证代码中指定个人访问令牌。这些令牌在 Azure 网页上生成：用户设置 -> 个人访问令牌。

下面的代码片段工作正常。请确保您的令牌具有读写代码权限，否则您将无法将文件推送到存储库。

// collectionUri, projectName, repoName and token are specified outside this block
var connection = new VssConnection(new Uri(collectionUri), new VssBasicCredential("", token));
using (var ghc = connection.GetClient<GitHttpClient>())
{
    var items = ghc.GetItemsAsync(projectName, repoName, scopePath: "/Path/To/Items").Result;
    foreach (var item in items)
    {
        Console.WriteLine($"{item.ObjectId}: {item.Path}")
    }
}
