I want to append or merge 2 json data . I wrote following code :

airsegmentss := []models.Airsegments{}
for _, flt := range flights {
    for _, arg := range airsegments {
        if arg.Availstring == flt.Availstring {
            airsegmentss = append(airsegmentss, arg)
            flightss := models.Flights{
                Airsegments: airsegmentss,
            }
            fmt.Println(flightss)
            flightssJson, err := json.Marshal(flightss)
            if err != nil {
                panic(err)
            }
            fmt.Println(string(flightssJson))
        }
    }
}

It gives following error which is not valid:

How do I append 2 or more json data . It should check if conditions and if two id of 2 or more json data matches then one json data should append with another one.

Note: In php code:

$air  = array();
$flights = $flights->map(function($item) use ($airsegments){
              foreach($airsegments as $airsegment)
              {
                if(preg_replace('/[^A-Za-z0-9\-]/', '',($airsegment['availstring'].''.$airsegment['id']))
                  == preg_replace('/[^A-Za-z0-9\-]/', '',($item['availstring'].''.$item['id'])))
                {
                  $air[]   = $airsegment;
                  }
                 }
                return collect($item)->put('airsegments', $air);
              });

The above code works perfectly in php. Since I am rewriting the whole php code in golang.

I made a example(most of it to setup with the same data), didn't have your models, so please substitute the proper types. This should do what you want.

CodePudding user response：

You can always put those 2 json-texts inside another:

{
  "firstModel": XXX
  "secondModel": YYY
}

if XXX is the content of your first and YYY is the second, then you can address both of them separately.
