Magento 2 REST API post json array and get response

[jacktorris]

I am using rest services in magento 2.  Using rest services i want to save data in my custom table.  To get the post data i am writing following code but it's not getting the posted date in API.  It givens passed array instead of string.  How can i post JSON array in REST api and save  get that posted data in model method?

 $this->request->getPost()  or   $this->request->getPostValues();   not working and throwing error.

EnquiryInterface.php file code:

namespace Comapny\Modulename\Api;
 interface EnquiryInterface
{

public function getenquirydata($paramaters);

}

webapi.xml

<route url="/V1/company/enquiry" method="POST">
     <service class="Comapny\Modulename\Api\EnquiryInterface" method="getenquirydata"/>
       <resources>
          <resource ref="anonymous"/>
      </resources>
</route>

di.xml

 <preference for="Comapny\Modulename\Api\EnquiryInterface" type="Comapny\Modulename\Api\Enquiry" />

Model/Enquiry.php

namespace Comapny\Modulename\Model;

use Magento\Framework\Exception\InputException;
use Magento\Framework\Exception\NoSuchEntityException;
 use Magento\Framework\App\RequestInterface;
class Enquiry extends \Magento\Framework\Model\AbstractModel
{

protected $request;

public function __construct(

 RestRequest $request,

){

 $this->request = $request;

}

public function getenquirydata($paramaters){

 $post= $this->request->getPost();

return $paramaters;

}

}

Hi @jacktorris

okay  i have seen the code you posted and understand the actual issue !

From your Model when you are returning parameters at that time you required to send data in json_encode format.

Below is the full modified code for your model file : 

Model/Enquiry.php

namespace Comapny\Modulename\Model;

use Magento\Framework\Exception\InputException;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\App\RequestInterface;
class Enquiry extends \Magento\Framework\Model\AbstractModel
{

protected $request;

public function __construct(

RestRequest $request,

){

$this->request = $request;

}

 

public function getenquirydata($paramaters){

$post= $this->request->getPost();

// if you are trying to return $post over here then you need to encode post data into json like below :

$post = json_encode($this->request->getPost());

// if you are trying to return $paramaters; over here then you need to encode post data into json like below :

$paramaters; = json_encode($this->request->getPost());
return $paramaters;

}
}

Then check it will works and returns data in string format !

Hope it helps

I am already posting the data in json format through postman in following format:

{

paramters:{

"name":"Test",

"Phone":"25423423423",

"email" : "test@test.com"

}

}

Posting data in above format despite when its not showing data in model.

In mode if i try $this->request->getParam()  or $this->request->getPost()   it doesn't show the paramaters posted through postman body,.

use below code will give you body parameters which we have pass as a post data

 /**
     * @var \Magento\Framework\Webapi\Rest\Request
     */
    protected $request;
 
    /**
     * constructor
     *
     * @param \Magento\Framework\Webapi\Rest\Request $request
     */
    public function __construct(
        \Magento\Framework\Webapi\Rest\Request $request
    ) {
        $this->request = $request;
    }
 
    /**
     * {@inheritdoc}
     */
    public function getPostParams()
    {
		return $this->request->getBodyParams();
    }

This works for REST for SOAP 

$this->request->getContent()

Worked well!
