EasyAR Spatial Map suele almacenar una gran cantidad de datos de mapas espaciales. Este capítulo describe cómo obtener detalles de Spatial Map y listas paginadas.
Después de entrar en la página de detalles, puede ver las propiedades completas del Spatial Map, incluidas:
Para desarrolladores que necesitan integración con su propio backend, se recomienda gestionar mediante REST API.
Reemplace los marcadores de posición por los parámetros reales y ejecute el script curl
- Your-URL → Cloud URL real
- Your-Token → API Key Authorization Token real
- Your-SpatialMap-AppId → SpatialMap appId real
curl -X GET "https://armap-api-<cn1|na1>.easyar.com/maps?appId=<Your-SpatialMap-AppId>" \
-H "Content-Type: application/json" \
-H "Authorization: <Your-Token>"
Descargue el código de ejemplo Java
Importe el proyecto con Maven
Step 1. Abra el código de ejemplo ListMaps.java
Step 2. Modifique las variables globales y sustitúyalas por los parámetros de autenticación de su checklist de preparación
- SpatialMap AppId
- API Key / API Secret
- Cloud URL

Step 3. Ejecute Main
Step 1. Copie el código de ejemplo en listmap.js y modifique Token, appId y Cloud URL
Step 2. Ejecute
npm install axios
node listmap.js
Si necesita cambiar la estrategia de pagination, pase parámetros de pagination
- pageSize: tamaño de página
- pageNum: número de página
const axios = require('axios');

}
}
if (require.main === module) {

}
module.exports = MapService;
Paso 1. Copie el código de ejemplo en listmap.php y modifique Token, appId y Cloud URL
Paso 2. Ejecute
php listmap.php
Si necesita cambiar la estrategia de paginación, pase los parámetros de paginación
- 'pageSize': tamaño de página
- 'pageNum': número de página

- Entorno de ejecución
- Unity 2020 LTS o posterior
- Scripting Backend: se admiten Mono e IL2CPP
- API Compatibility Level: .NET Standard 2.1 (recomendado)
Step 1: Prepare el archivo de imagen
- Cree un directorio en el proyecto Unity:
Assets/
└── Scripts/
└── ListMap.cs
using System.Collections;
using UnityEngine;
using UnityEngine.Networking;
public class ListMap : MonoBehaviour
{
[Header("Config")]
public string apiBaseUrl = "https://armap-api-<cn1|na1>.easyar.com";
public string authorizationToken = "YOUR API KEY AUTH TOKEN";
public string spatialMapAppId = "SpatialMap-AppId";
public int pageSize = 5;
public int pageNum = 1;

Debug.Log(request.downloadHandler.text);
}
else
{
Debug.LogError("List maps failed:");
Debug.LogError(request.error);
Debug.LogError(request.downloadHandler.text);
}
}
}
Step 3: Configure los parámetros (Inspector)
Modifique en el panel Inspector:
- Api Url
- Authorization Token
- Spatial Map App Id
- page size
- page num
Solo necesita modificar estos elementos para ejecutar, rellenando los parámetros preparados en la checklist de preparación
Step 4: Ejecutar
- Haga clic en Play
- Consulte el resultado en Console:
- Correcto: devuelve JSON (incluye result)
- Fallo: HTTP / información de error
