チャネル `git on the server`はPHPを経由して呼び出します

Question

git pullとgit pushのコマンドをPHPに渡すことは可能ですか？これにより

私はgit originとしてhttps://example.com/projectname?credentials=xxxを設定します、と私はpullまたはpushを実行するとき、彼らは大丈夫だ場合、その後、PHPスクリプトは、資格情報を分析し、Gitのレポへのgitにより送信された元のコマンドを送信する意味フォルダに移動してから、ユーザーに応答が返されますか？

これを達成するためにgit-http-backendを使用することができますか、または他の方法がありますか？

Answer 1

私は最終的にそれがプル関連のコマンドのために働くようになったが、プッシュのため

static $basegitdir = '/path/to/where/bare/git/repos/live';

    try { 
     // In my implementation, func_get_args will return e.g. ['info', 'refs'], basically, all of the stuff git appends to the remote url 
     $arguments = func_get_args(); 
     // Remove the first argument 
     array_unshift($arguments, "{$packagename}.git"); 
     // Will resolve to something like '/repo.git/info/refs' 
     $path = '/' . implode('/', $arguments); 
     $service = filter_input(INPUT_GET, 'service');

      // PATH_INFO <MUST> evaluate to something along the lines of '/repo.git/info/refs'. Note, basegitdir has been 
      // dropped from the beginning of the path. This is because Git joins GIT_PROJECT_ROOT and PATH_INFO. Also note the lack of a trailing slash after refs 
      'PATH_INFO' => $path, 
      'REMOTE_ADDR' => filter_input(INPUT_SERVER, 'REMOTE_ADDR'),
