【问题描述】:
我收到了来自 Api 的响应,如下所示:
property: Array(100)
0: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
1: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
2: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
3: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
我想要地址对象中一些指定字段的列表,例如国家和 oneLine,但对于属性的每个索引
数组
address:
country: "US"
countrySubd: "CA"
line1: "1702 ELKHORN RD"
line2: "ROYAL OAKS, CA 95076"
locality: "Royal Oaks"
matchCode: "ExaStr"
oneLine: "1702 ELKHORN RD, ROYAL OAKS, CA 95076"
postal1: "95076"
postal2: "9218"
postal3: "R002"
我已经为如何在我的 graphql 架构页面中为此编写架构而苦苦挣扎了 2 天。有人能帮帮我吗?
这是我一直在尝试的,但数据一直为空值
require("es6-promise").polyfill();
require("isomorphic-fetch");
const {
GraphQLString,
GraphQLList,
GraphQLSchema,
GraphQLObjectType,
GraphQLInt
} = require("graphql");
const Identifier = new GraphQLObjectType({
name: "identifier",
fields: () => ({
obPropId: { type: GraphQLInt }
})
});
const AddressType = new GraphQLObjectType({
name: 'Address',
fields: () => ({
country: { type: GraphQLString },
oneLine: {type: GraphQLString }
})
})
const RootQuery = new GraphQLObjectType({
name: "RootQueryType",
fields: {
property: {
type: new GraphQLList(Identifier),
resolve(parent, args) {
return fetch(
"https://api.gateway.attomdata.com/propertyapi/v1.0.0/property/address?postalcode=95076&page=1&pagesize=100",
{
headers: {
Accept: "application/json",
APIKey: "XXXXXXXXXXXXXXXXXXXX"
}
}
)
.then((response) => {
const jsonResponse = response.json();
return jsonResponse
}).then((jsonResonse) => console.log(JSON.stringify(jsonResonse)))
.then(res => res.data)
.catch(error => {
console.log(error);
});
}
}
}
});
module.exports = new GraphQLSchema({
query: RootQuery
});
Im running it on a express server and do my checks on localhost:5000/graphql

请显示所有相关代码,包括您尝试过的代码,以及您遇到的错误或意外行为。
-
对我来说,您似乎缺少介于
Address和查询字段之间的类型。你介绍type Property { id: Identifier, address: Address }。然后你的属性查询将返回一个数组。 codesandbox.io/s/elegant-ellis-9f1yg -
@Herku 谢谢人 就是这样!!

如果你不介意我会添加一个答案
