Laravel JWTAuth::attempt($credentials) not working in Ubuntu Server - php

Question

PROBLEM: JWTAuth::attempt($credentials) is working in my windows local machine. When user calls /userLogin by providing credentials(username & password), it verifies the credentials and creates a token for the user. But same code: JWTAuth::attempt($credentials) is NOT working when I deploy the project on to Ubuntu Server.
DESCRIPTION:
I am using tymondesigns/jwt-auth for implementing JSON Web Tokens in my Laravel 5.1 project. I have built 2 REST APIs: /userRegister & /userLogin.
Here is code for /userRegister in UserController.php:
public function userRegister(Request $request)
{
$validator = Validator::make($request->all(), [
'email' => 'required',
'username' => 'required',
'password' => 'required',
'country' => 'required',
'zip_code' => 'required',
'date_time' => 'required',
'gender' => 'required',
]);
try
{
if ($validator->fails())
throw new Exception($validator->errors(), 409);
$name = $request->input('name');
$email = $request->input('email');
$username = $request->input('username');
$password = bcrypt($request->input('password'));
$country = $request->input('country');
$zip_code = $request->input('zip_code');
$fb_login = $request->input('fb_login');
$registration_date = $request->input('date_time');
$gender = $request->input('gender');
$user_email = UserProfile::where('email','=',$email)->first();
if($user_email!=null)
{
throw new Exception("User with this email is already registered");
}
$check_username = UserProfile::where('username','=', $username)->first();
if ($check_username != null)
{
throw new Exception("User with this username is already registered. Please use different username");
}
$saveUser = new UserProfile();
$saveUser->name=$name;
$saveUser->email=$email;
$saveUser->username=$username;
$saveUser->password=bcrypt($password);
$saveUser->country=$country;
$saveUser->zipcode=$zip_code;
$saveUser->gender=$gender;
$saveUser->fb_login=$fb_login;
$saveUser->registration_date=$registration_date;
$build_trial_date = new Carbon($registration_date);
$trial_end_date = $build_trial_date->addDays(30);
$saveUser->trial_end_date=$trial_end_date;
$result = $saveUser->save();
if (!$result)
throw new Exception("Error in registration. Please try again.");
$user_id = $saveUser->id;
$loginUser = UserProfile::find($user_id);
$loginUser->update(['logged_in' => 1]);
return ResponseService::buildSuccessResponse("User registered successfully");
}
catch(Exception $e)
{
$data = [
'error' => true,
'result' => [
'status_code' => $e->getCode(),
'message' => $e->getMessage(),
]
];
$result = ResponseService::buildFailureResponse($data);
return $result;
}
}
As you can notice I am using bcrypt() for before saving password.
Now, here is code for /userLogin in UserController:
public function userLogin(Request $request)
{
// grab credentials from the request
$credentials = $request->only('username', 'password');
Log::info("username and password obtained from Request: ".json_encode($credentials));
try
{
if(JWTAuth::attempt($credentials)) // For Logging
{
Log::info("$ token = JWTAuth::attempt $ credentials Result: TRUE");
}else{
Log::info("$ token = JWTAuth::attempt $ credentials Result: FALSE");
}
// attempt to verify the credentials and create a token for the user
if (! $token = JWTAuth::attempt($credentials))
{
return response()->json(['error' => 'invalid_credentials'], 401);
}
} catch (JWTException $e) {
// something went wrong whilst attempting to encode the token
return response()->json(['error' => 'could_not_create_token'], 500);
}
Log::info("Generated token is: ".json_encode(compact('token')));
// all good so return the token
return response()->json(compact('token'));
}
/userRegistration Api is working both in my windows local m/c as well
as in Ubuntu server. Also bcrypt() on password is working in
it.
BUT, /userLogin is working in my windows local m/c but not working in
Ubuntu Server.
Help me solve this silent-dead-hidden error. TIA.
FURTHER DETAILS:
I have also cross-checked jwt.php file both in my windows and ubuntu server. They are having same configuratons. Also I have used php artisan jwt:generate on ubuntu server.

I finally could solve the problem when I went through the code again. Luckily I could noice that! Here is the mistake I did. At some point in time I have added this code bcrypt() like this:
$password = bcrypt($request->input('password'));
But I was already using bcrypt() before saving $password into the database.
$saveUser = new UserProfile();
$saveUser->password=bcrypt($password);
Since it was encrypting twice before saving to database, when I called /userLogin api, JWTAuth::attempt($credentials) was checking for credintials and it was not able to validate. So I removed bcrypt() at one place and now its working fine. [Solved].
