I need to send associative array in response. Keys can be dynamic like

{
 'a':'1',
 'b':'2'
}

I already tried mixed[], mixed, string, string[], array and array[]. But I always get following result.

{
 '1',
 '2'
}

  • @BirjitsinhZala - Yes I tried, it didn't worked. Dec 27, 2019 at 4:24
  • hiii, have you checked my updated answere? Dec 27, 2019 at 5:30
  • Hi, yes. First option is not working. Second option is working but it is adding escape character '\' in the response like "[{\"a\":\"1\",\"b\":\"2\"}]". Seems I will need to handle it client side. Dec 27, 2019 at 5:38
  • I mean to say create new file interface AssociativeArrayItemInterface Dec 27, 2019 at 5:49

First create this interface in your app/code/Vendor/Module/Api/Data

/**
 * Interface which represents associative array item.
 */
interface AssociativeArrayItemInterface
{
    /**
     * Get key
     * 
     * @return string
     */
    public function getKey();

    /**
     * Get value
     * 
     * @return string
     */
    public function getValue();
}

Apply @return \Vendor\Module\Api\Data\AssociativeArrayItemInterface[] datatype for on comment

/**
    * @return \Vendor\Module\Api\Data\AssociativeArrayItemInterface[]
    **/
    public function getSettings();

    /**
    * @return \Vendor\Module\Api\Data\AssociativeArrayItemInterface[]
    **/
    public function getExtra();

SECOND OPTION: send data in below formate

[{"a":"1","b":"2"}]

  • Or second option send in array: [{"a":"1","b":"2"}] Dec 26, 2019 at 14:15
  • Your second option cannot work as the {} symbols can't be used.
