Я начинаю с Apollo GraphQL (используя Axios) и сталкиваюсь с проблемой, когда внешний API отправляет массив.Я не могу получить переменные внутри объектов.Я уже пытался несколькими способами, и нигде не могу найти помощь.
const axios = require ('axios');
const {GraphQLObjectType, GraphQLSchema, GraphQLInt,
GraphQLList, GraphQLString } = require('graphql');
const FeedingType = new GraphQLObjectType({
name: 'Feeding',
fields: () => ({
sentry_objects : {type : new GraphQLList(SentryType)},
})
})
//Sentry Objects
const SentryType = new GraphQLObjectType({
name: 'Sentry',
fields: () => ({
designation : {type : GraphQLString},
})
})
//Root Query
const RootQuery = new GraphQLObjectType({
name: 'RootQueryType',
fields: {
sentry: {
type: new GraphQLList(SentryType),
resolve(parent, args){
return axios
.get('https://api.nasa.gov/neo/rest/v1/neo/sentry?is_active=true&page=0&size=50&api_key=DEMO_KEY')
.then(res => res.data);
}
},
И это JSON от API:
{
"links": {
"next": "https://api.nasa.gov/neo/rest/v1/neo/sentry?is_active=true&page=1&size=50&api_key=DEMO_KEY",
"self": "https://api.nasa.gov/neo/rest/v1/neo/sentry?is_active=true&page=0&size=50&api_key=DEMO_KEY"
},
"page": {
"size": 50,
"total_elements": 908,
"total_pages": 19,
"number": 0
},
"sentry_objects": [
{
"links": {
"near_earth_object_parent": "https://api.nasa.gov/neo/rest/v1/neo/3012393?api_key=DEMO_KEY",
"self": "https://api.nasa.gov/neo/rest/v1/neo/sentry/3012393?api_key=DEMO_KEY"
},

"is_active_sentry_object": true,
"average_lunar_distance": 14.2337865829
},
}
Попытка получить переменные "sentry_objects", тестирую с "обозначением", но я просто получаю ошибки вроде:
{
"errors": [
{
"message": "Expected Iterable, but did not find one for field RootQueryType.sentry.",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"sentry"
]
}
],
"data": {
"sentry": null
}
}
Спасибо, что прочитали:)
