使用数据库用户提供程序时如何在 Laravel 中创建密码重置方法

要编写自己的密码重置逻辑，您仍然可以使用现成的默认迁移，或者只是创建自己的migrations.最重要的部分是 token .由于您正在进行自己的密码重置，您需要做出以下几个决定:

• Will the token expire?
• 用户可以多次使用同一令牌吗？

You will need 2 pages, 4 different routes and 4 different functions in the same controller. The 'I forgot my password' page and the 'Reset password' page. In the first page, display a form where you take the user email. And post to the following controller.

//to be added on top as use statements 
use DB;
use Auth;
use Hash;
use Carbon;
use App\User;

public function sendPasswordResetToken(Request $request)
{
    $user = User::where ('email', $request->email)-first();
    if ( !$user ) return redirect()->back()->withErrors(['error' => '404']);

    //create a new token to be sent to the user. 
    DB::table('password_resets')->insert([
        'email' => $request->email,
        'token' => str_random(60), //change 60 to any length you want
        'created_at' => Carbon::now()
    ]);

    $tokenData = DB::table('password_resets')
    ->where('email', $request->email)->first();

   $token = $tokenData->token;
   $email = $request->email; // or $email = $tokenData->email;

   /**
    * Send email to the email above with a link to your password reset
    * something like url('password-reset/' . $token)
    * Sending email varies according to your Laravel version. Very easy to implement
    */
}

第二部分，当用户点击链接时

/**
 * Assuming the URL looks like this 
 * http://localhost/password-reset/random-string-here
 * You check if the user and the token exist and display a page
 */

 public function showPasswordResetForm($token)
 {
     $tokenData = DB::table('password_resets')
     ->where('token', $token)->first();

     if ( !$tokenData ) return redirect()->to('home'); //redirect them anywhere you want if the token does not exist.
     return view('passwords.show');
 }

Display a page with a form containing 2 inputs - New password password or whateveer you want - New password confirmation password_confirm or whatever you want The form should post to the same URL mapped to the following controller. Why? because we still need to use the token to find the actual user.

 public function resetPassword(Request $request, $token)
 {
     //some validation
     ...

     $password = $request->password;
     $tokenData = DB::table('password_resets')
     ->where('token', $token)->first();

     $user = User::where('email', $tokenData->email)->first();
     if ( !$user ) return redirect()->to('home'); //or wherever you want

     $user->password = Hash::make($password);
     $user->update(); //or $user->save();

     //do we log the user directly or let them login and try their password for the first time ? if yes 
     Auth::login($user);

    // If the user shouldn't reuse the token later, delete the token 
    DB::table('password_resets')->where('email', $user->email')->delete();

    //redirect where we want according to whether they are logged in or not.
 }

别忘了添加路由

Route::get('password-reset', 'PasswordController@showForm'); //I did not create this controller. it simply displays a view with a form to take the email
Route::post('password-reset', 'PasswordController@sendPasswordResetToken');
Route::get('reset-password/{token}', 'PasswordController@showPasswordResetForm');
Route::post('reset-password/{token}', 'PasswordController@resetPassword');
