A step-by-step guide to receiving Json input in a CakePhp Restful API through the PUT method

A step-by-step guide to receiving Json input in a CakePhp Restful API through the PUT method

Managing data through passing IDs in URL format like /apis/view/id.json allows me to view and delete data.

public function view($id) {
        $api = $this->Api->findById($id);
        $this->set(array(
            'api' => $api,
            '_serialize' => array('api')
        ));
    }

Now, I want to extend this functionality by adding an add and edit feature where JSON formatted data can be passed in the HTTP body for storage or editing in the database.

While exploring solutions on how to implement this, I came across a challenge that I couldn't fully comprehend: CakePHP API PUT with JSON input

I am particularly confused about how to use:

$data = $this->request->input('json_decode');

To achieve the desired functionality. Any guidance on this would be greatly appreciated.

To utilize the Add function, simply follow the documentation by adding .json to the URL. By doing so, the URL for posting data will transform into /apis.json, which will automatically trigger the add() method.

If you provide JSON values for email and password in this format:

{"email":"example@example.com","password":"123456"}

public function add(){

     $data=$this->request->input('json_decode', true ); //$data captures the JSON input. Remember to include 'true' to store it as an array.

     $data = $this->Api->findByEmailAndPassword($data['email'],$data['password']);
//a simple check to compare the posted values with the ones in the "Api" model 
         if($data) {$this->set(array(
                          'data' => $data,
              '_serialize' => array('data')));}
        else{ $this->set(array(
            'data' => "sorry",
            '_serialize' => array('data')));}

      }//  The final if-else statement verifies if $data is true - if the values match, it will return the input values in a JSON response. If the email-password combination is not found, it will respond with "Sorry" in JSON format.

I hope that clarifies your query! The Put operation functions similarly, checking for existing data and either creating or modifying it accordingly. Feel free to ask if you have any more questions :)

According to the documentation provided in the link, the function CakeRequest::input() is used to read raw input data and can be decoded if needed.

By using

$this->request->input('json_decode')

, you can access the decoded JSON input. If the format aligns with Cake conventions, you can directly pass it to a save method of the Model.

Below is a basic example (not tested):

public function add()
{
    if($this->request->is('put'))
    {
        $data = $this->request->input('json_decode', true);

        $api = $this->Api->save($data);
        $validationErrors => $this->Api->validationErrors;

        $this->set(array
        (
            'api' => $api,
            'validationErrors' => $validationErrors,
            '_serialize' => array('api', 'validationErrors')
        ));
    }
}

This code snippet attempts to save the data and provides the save result along with any validation errors that may occur.

If the input data does not adhere to Cake conventions, you will need to adjust the transformation accordingly.
