如何使用电子邮件而不是通过id更新laravel rest api中的数据

Route::put('/users/{email}', 'UserController@updateByEmail');

public function updateByEmail(Request $request, $email)
{
    // 验证电子邮件是否存在于数据库中
    $user = User::where('email', $email)->first();

    if ($user) {
        // 更新数据
        $user->name = $request->input('name');
        $user->email = $request->input('email');
        // 其他字段更新...

        // 保存更新
        $user->save();

        return response()->json(['message' => 'User updated successfully']);
    } else {
        return response()->json(['message' => 'User not found'], 404);
    }
}

curl -X PUT -H "Content-Type: application/json" -d '{"name":"John Doe","email":"john@example.com"}' http://your-api-url/users/john@example.com
