Eksempler
I denne artikel:
I følgende eksempel går vi ud fra en shop med 42 ordrer i alt.
Hent ordrer
Hvis vi vil hente ID, sprog, site ID og ordrekommentarer for alle ordrer i shoppen, kan vi benytte følgende forespørgsel:
POST
query {
orders {
data {
id
languageISO
siteId
orderComment
}
}
}
Endpoint:
shop99999.mywebshop.io/api/graphql
(Erstat "shop99999" med dit eget shop nummer)
Response
{
"data": {
"orders": {
"data": [
{
"id": "1",
"languageISO": "DK",
"siteId": "1"
},
...,
{
"id": "42",
"languageISO": "DK",
"siteId": "1"
}
]
}
}
}
Brug af pagination
For at begrænse antallet af returnerede resultater, kan vi supplere med paginationsmuligheder. Følgende forespørgsel demonstrerer hentning af højst 2 ordrer per side, med resultater fra side 3:
POST
query {
orders (pagination:{
limit: 2,
page: 3
}) {
pagination {
currentPage
from
perPage
to
total
}
data {
id
languageISO
siteId
}
}
}
Endpoint:
shop99999.mywebshop.io/api/graphql
Response
{
"data": {
"orders": {
"pagination": {
"currentPage": 3,
"from": 5,
"perPage": 2,
"to": 6,
"total": 6
},
"data": [
{
"id": "8",
"languageISO": "DK",
"siteId": "1"
},
{
"id": "9",
"languageISO": "DK",
"siteId": "1"
}
]
}
}
}
Brug af sortering
Det er ligeledes muligt at sortere de returnerede resultater i forhold til et givent felt, i en given ordre:
POST
query {
orders (order:{
field: id,
direction: DESC
}) {
data {
id
}
}
}
Endpoint:
shop99999.mywebshop.io/api/graphql
Response
{
"data": {
"orders": {
"data": [
{
"id": "42"
},
{
"id": "41"
},
...,
{
"id": "1"
}
]
}
}
}
Brug af søgning
En anden måde at begrænse de returnerede resultater på, er ved at benytte søgeparametre. Følgende eksempel viser hvordan man henter alle ordrer, med ordre ID mindre end 3, og større end 41:
POST
query {
orders (search:[
{
field: id,
comparator: LESS_THAN
value:"3"
},
{
field: id,
comparator: GREATER_THAN
value:"41",
operator:OR
}
]) {
data {
id
}
}
}
Endpoint:
shop99999.mywebshop.io/api/graphql
Response
{
"data": {
"orders": {
"data": [
{
"id": "1"
},
{
"id": "2"
},
{
"id": "42"
}
]
}
}
}
Det hele i kombination
Vi kan kombinere alle ovenstående eksempler i en enkelt forespørgsel:
POST
query {
orders(
pagination:{limit:3,page:2}
order:{field:id, direction:DESC}
search: [{field: id, comparator: GREATER_THAN, value: "30"}]
) {
data {
id
createdAt
}
}
}
Endpoint:
shop99999.mywebshop.io/api/graphql
Response
{
"data": {
"orders": {
"data": [
{
"id": "39",
"createdAt": "2019-04-08T09:09:44+00:00"
},
{
"id": "38",
"createdAt": "2019-04-08T08:36:43+00:00"
},
{
"id": "37",
"createdAt": "2019-04-05T14:10:05+00:00"
}
]
}
}
}
