I am trying to establish connectivity with google maps api using service account. I have a project in place in google maps api, and I have the relvant clientID, .p12 key, email address. I am using google libraries to get the credentials and to call the API as below.
CODE:
package mapsengine;import com.google.api.client.auth.oauth2.Credential;
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.mapsengine.MapsEngine;
import com.google.api.services.mapsengine.model.Map;
import com.google.api.services.mapsengine.model.Layer;
import java.io.File;import java.io.IOException;
import java.util.Collections;
public class Main { /** Provide the ID of the map you wish to read. */
private static final String MAP_ID = "my map id i gave";
private static final String APPLICATION_NAME = "Google-MapsEngineApiSample/1.0";
private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
private static final JsonFactory JSON_FACTORY = new JacksonFactory();
private static final String SERVICE_ACCOUNT_EMAIL= "[email protected]";
private static Credential authorize() throws Exception {
GoogleCredential credential = new GoogleCredential.Builder().setTransport(HTTP_TRANSPORT
) .setJsonFactory(JSON_FACTORY)
.setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
.setServiceAccountScopes(Collections.singleton("https://www.googleapis.com/auth/mapsengine"))
.setServiceAccountPrivateKeyFromP12File(new File("key.p12"))
.build();
credential.refreshToken();
System.out.println(credential);
return credential;
}
public static void main(String[] args)
{ try { // Authorize this application to access the user's data.
Credential credential = authorize();
// Create an authorized Maps Engine client with the credential.
MapsEngine mapsEngine = new MapsEngine.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential) .
setApplicationName(APPLICATION_NAME).build();
System.out.println(mapsEngine);
// Make a request to get the details of a particular map.
// Map map = mapsEngine.maps().get(MAP_ID).execute();
System.out.println(map.getName());
System.out.println(map.getDescription());
}
catch (IOException e) {
System.out.println(e.getMessage());
} catch (Throwable t) {
t.printStackTrace();
}
}
}`
I am getting an error as 403 Forbidden { "code" : 403, "errors" : [ { "domain" : "mapsengine", "location" : "id", "locationType" : "parameter", "message" : "Permission denied (reader access required).", "reason" : "noReaderAccess" } ], "message" : "Permission denied (reader access required)." }
But I am able to see that the service email account which I am using has edit access, also i tried by giving view access. What else I am missign here. Please help.
