I use Fetch in ReactJs to send a request to api Moleculer like this :

```
 var data ={
            'ordername' : 'PUG',
            'receivername' : 'AnSama'
        }
        fetch(url,{
            method: 'POST',
            header: {              
                'Accept': 'application/json',
                'Content-Type': 'application/json',
              },
              body : data
        })
            .then(res => {return res.json()})
                .then(
                    (result) => {
                        alert(JSON.stringify(result));
                    },
                    (error) => {
                        alert('error');
                    }
                )

```

Then, I want to get body of request in Moleculer (Framework of NodeJS). How can i do?
