.NET Core下操作Git，自動提交程式碼到 GitHub
- 2019 年 10 月 3 日
- 筆記
.NET Core 3.0 預覽版發布已經好些時日了，部落格園也已將其用於生產環境中，可見 .NET Core 日趨成熟
回歸正題，你想蓋大樓嗎？想 GitHub 首頁一片綠嗎？今天拿她玩玩自動提交程式碼至 GitHub。
安裝項目模板
dotnet new --install "Microsoft.DotNet.Web.ProjectTemplates.3.0" dotnet new worker創建項目
直接使用 .NET CLI 創建一個 Work Service 的項目
dotnet new worker -o AutomaticPush用 Visual Studio 2019 打開項目可以看到以下程式碼
// Program.cs public class Program { public static void Main(string[] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureServices((hostContext, services) => { services.AddHostedService<Worker>(); }); }- 從 3.0 起 WebHost 被 Host 取代了
CreateHostBuilder創建 Host 並在ConfigureServices中調用.AddHostedService<Worker>()
// Worker.cs public class Worker : BackgroundService { private readonly ILogger<Worker> _logger; public Worker(ILogger<Worker> logger) { _logger = logger; } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { while (!stoppingToken.IsCancellationRequested) { _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now); await Task.Delay(1000, stoppingToken); } } }Worker 繼承了 BackgroundService，在 override ExecuteAsync 方法中完成自動提交的程式碼
.NET 下操作 Git 需要用到一個庫 LibGit2Sharp，同時支援 .NET Framework 及 .NET Core
在項目中安裝使用
Install-Package LibGit2SharpLibGit2Sharp 簡單使用
-
Repository.Init(@"D:Work")在指定路徑創建一個新的 Git 倉庫，相當於git init -
Repository.Clone("https://github.com/Meowv/Blog.git", @"D:Work")拉取一個遠程倉庫到本地，相當於git clone -
using (var repo = new Repository(@"D:Blog")){}打開本地存在的 Git 倉庫 -
獲取 Branch
using (var repo = new Repository(@"D:Blog")) { var branches = repo.Branches; foreach (var item in branches) { } } -
獲取 Commits
using (var repo = new Repository(@"D:Blog")) { foreach (var commit in repo.Commits) { } } -
獲取 Tags
using (var repo = new Repository(@"D:Blog")) { foreach (var commit in repo.Tags) { } } -

自動 Push 程式碼蓋大樓
有了以上基礎，就可以實現自動生成文件，push 程式碼到 GitHub 了。
新建一個配置文件，存放我們 GitHub 倉庫以及帳號密碼等重要資訊
{ "repository": "本地git倉庫絕對路徑", "username": "GitHub帳號", "password": "GitHub密碼", "name": "提交人", "email": "郵箱" }在ExecuteAsync中讀取配置文件資訊
var configurationRoot = new ConfigurationBuilder().AddJsonFile("config.json").Build(); var path = configurationRoot["repository"]; var username = configurationRoot["username"]; var password = configurationRoot["password"]; var name = configurationRoot["name"]; var email = configurationRoot["email"];git會自動檢測文件變化，所以就先自動按日期創建.log文件，不斷生成內容然後提交
while (!stoppingToken.IsCancellationRequested) { var fileName = $"{DateTime.Now.ToString("dd")}.log"; var content = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"); // 寫入內容 WriteText(path, fileName, content); using (var repo = new Repository(path)) { // Stage the file Commands.Stage(repo, "*"); // Create the committer's signature and commit var author = new Signature(name, email, DateTime.Now); var committer = author; // Commit to the repository var commit = repo.Commit(content, author, committer); // git push var options = new PushOptions { CredentialsProvider = new CredentialsHandler((url, usernameFromUrl, types) => { return new UsernamePasswordCredentials() { Username = username, Password = password }; }) }; repo.Network.Push(repo.Branches["master"], options); } Console.WriteLine(content); // 等待60秒繼續執行... await Task.Delay(60000, stoppingToken); } private static void WriteText(string path, string fileName, string content) { path = Path.Combine(path, DateTime.Now.ToString(@"yyyy\MM")); if (!Directory.Exists(path)) { Directory.CreateDirectory(path); } var filePath = Path.Combine(path, fileName); using var fs = new FileStream(filePath, FileMode.Append); using var sw = new StreamWriter(fs); sw.WriteLine(content); }至此，整個程式碼編寫部分結束，項目發布後可以選擇sc.exe註冊為Windows服務，在這裡推薦使用nssm(一個服務封裝程式)，好了，趕緊蓋大樓去吧~~
