Aliasgar Lokhandwala • 1 year ago

Hi All,

Has anyone solved this problem?

Use JsonReader.setLinient(true) to accept malformed JSON at line 1 column 1 path$

Edgar Valdés • 1 year ago

In my case, it was a problem with utf8 encoding. In the file DBOperations.php, I added the utf8 charset.

$this -> conn = new PDO("mysql:host=".$this -> host.";dbname=".$this -> db, $this -> user, $this -> pass,array('charset'=>'utf8'));

$this -> conn -> query("SET CHARACTER SET utf8");

Suraj Giri • 1 year ago

Armand • 1 year ago

Hi for those that had the same problem as me I just came across my error. I had everything working as I was working with a cpanel site however when I tried testing the web service it kept on only showing: "Learn2Crack Login API". This was by using postman as per guidance from video tutorial. I had my path set as:
http://127.0.0.1/learn2crack-login-register

however after 2 days I discovered that I had a missing "/" and by adding that my path worked correctly and I succeeded as per video

from
http://127.0.0.1/learn2crack-login-register
to
http://127.0.0.1/learn2crack-login-register/

Fixed my error

how to register with this , what is the path or url ?and what fields to be put into postman

amreky2005 • 1 year ago

Thanks very much for sharing this!!

I just have a quick question if someone can help:

Using postman when I input:

{
"operation":"register",
"user":{
"name":"Raj Amal",
"email":"raj.amalw@learn2crack.com",
"password":"rajamalw"
}
}

And I do get a successful reply:

{
"result":"success",
"message":"User Registered Successfully !"
}

But when I check on the users created in phpmyadmin database there is nothing there. Any suggestions on what is causing this?

If I try to login as a user it fails indicating that nothing indeed was added to the database.

Any help will be very appreciated!!

getting this error after click on forgot password.... how to resolve

ahmad • 2 years ago

hello ...
please how can i edit the "php:// input" ??
i want to add a number text field in the registartion code ...

Raj Amal • 2 years ago

You can fetch the additional JSON object in PHP by

$newField = $user -> newField;

And while sending you need to add that field as JSON object to the existing JSON.

ahmad • 2 years ago

okii then how can i add number field in the jason ??

Thanks Raj!!!

B3NN1TH • 2 years ago

Had issues where i was getting invalid parameters ... make sure to have index.php in the @POST request.
Also I upgraded to PHP5.6 from PHP5.59 but not sure if that also helps... probably just a case of the @POST

@POST("myfolderurl/index.php")
Call<serverresponse> operation(@Body ServerRequest request);

Hey, i got a little question regarding on the mobile system. How to get rid off the verifyHash because i want to connect to my web system. The login of the mobile system expect encrypted password but my web system has no enryption password. I just figured out on how to register without enryption but i dont know how to get rid off the verifyHash that expect a enrypted password during log in. https://uploads.disquscdn.c...

Raj Amal • 2 years ago
public function checkLogin($email, $password) {
$sql = 'SELECT * FROM users WHERE email = :email';
$query = $this -> conn -> prepare($sql);
$query -> execute(array(':email' => $email));
$data = $query -> fetchObject();
$db_password = $data -> password;

if ($password == $db_password) ) {
$user["name"] = $data -> name;
$user["email"] = $data -> email;
$user["unique_id"] = $data -> unique_id;
return $user;
} else {
return false;
}
}

Assuming the column name in which you store password is password.

How do I get the JSON request and response ?

Yusuf • 2 years ago

I did exactly what you say and when i try in postman it says succesfull but i cant see anything created in phpmyadmin?

Sisekelo Dlamini • 2 years ago

How can I test it with Post man? I am not sure what to add in the parameters and what is the url I should use to test?

Yusuf • 2 years ago

Ifound the answer. I created table with GUI because SQL commands didn't work for some reason. And replaced the commands in DBOperations.php with
$query = $this->conn ->prepare("Insert Into users (name, email, encrypted_password, salt, unique_id) Values(:name, :email, :encrypted_password, :salt, :unique_id)");
$query->execute(array(':name' => $name, ':email' => $email, ':encrypted_password' => $encrypted_password, ':salt' => $salt, ':unique_id' => $unique_id));
