我試圖用graphql獲取一個座標數組。我使用的繼電器,貓鼬,和塗鴉貓鼬產生graphql類型從這些貓鼬模型:Graphql查詢數組
// Geometry
const GeometrySchema = new mongoose.Schema({
type: { type: String },
coordinates: [ Number ]
}, { _id: false });
// Country
const CountrySchema = new mongoose.Schema({
code: String,
name: String,
dictionary: [ { _id: false, value: String } ],
language: [ { _id: false, code: String, name: String } ],
loc: { type: { type: String }, geometries: [ GeometrySchema ] },
creationDate: Date,
modifiedDate: Date
});
const Country = mongoose.model('Country', CountrySchema);
這裏的產生graphql(graphql /公共事業):
type Country implements Node {
code: String
name: String
dictionary: [CountryDictionary]
language: [CountryLanguage]
loc: [CountryLoc]
creationDate: Date
modifiedDate: Date
_id: ID
id: ID!
}
type CountryConnection {
pageInfo: PageInfo!
edges: [CountryEdge]
count: Float
}
type CountryDictionary {
_id: Generic
value: String
}
input CountryDictionaryInput {
_id: Generic
value: String
}
type CountryEdge {
node: Country
cursor: String!
}
type CountryLanguage {
_id: Generic
code: String
name: String
}
input CountryLanguageInput {
_id: Generic
code: String
name: String
}
type CountryLoc {
type: String
coordinates: [Float]
}
input CountryLocInput {
type: String
coordinates: [Float]
}
使用graphiql我能得到這個國家的名稱:
{
country(id:"57b48b73f6d183802aa06fe8"){
name
}
}
我該如何檢索loc信息?
你嘗試了'{ 國家(ID: 「57b48b73f6d183802aa06fe8」){ 名 祿{ 座標 }} } ' ? –
是的我嘗試,我得到這個迴應: { 「statusCode」:400, 「error」:「Bad Request」, 「message」:「期望的Iterable,但沒有找到一個字段Country.loc。」 } – ric
這意味着,問題與服務器端實現有關。檢查是否在服務器端正確返回了一組座標。 –
