Question

我正在尝试使用服务帐户与google maps api建立连接。我在google maps api中有一个项目，我有relvant clientID，.p12密钥，电子邮件地址。我正在使用谷歌库来获取凭据并调用API，如下所示。

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= "asajdsjdheemqe@developer.gserviceaccount.com";

private static Credential authorize（）抛出Exception {         GoogleCredential凭证=新的GoogleCredential.Builder（）。setTransport（HTTP_TRANSPORT                 ）.setJsonFactory（JSON_FACTORY）
                .setServiceAccountId（SERVICE_ACCOUNT_EMAIL）                 .setServiceAccountScopes（Collections.singleton（＆＃34; https://www.googleapis.com/auth/mapsengine＆＃34））
                .setServiceAccountPrivateKeyFromP12File（新文件（＆＃34; key.p12＆＃34;））                 .build（）;
        credential.refreshToken（）;
        的System.out.println（凭证）;         返回凭证;

} 
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();    
}
}

}`

我收到错误403 Forbidden { ＆＃34;代码＆＃34; ：403，＆＃34;错误＆＃34; ：[{ ＆＃34;结构域＆＃34; ：＆＃34; mapsengine＆＃34;，＆＃34;位置＆＃34; ：＆＃34; id＆＃34;，＆＃34;的locationType＆＃34; ：＆＃34;参数＆＃34;，＆＃34;消息＆＃34; ：＆＃34;权限被拒绝（需要读者访问）。＆＃34;，＆＃34;理由＆＃34; ：＆＃34; noReaderAccess＆＃34; }]，＆＃34;消息＆＃34; ：＆＃34;权限被拒绝（需要读者访问）。＆＃34; }

但我能够看到我正在使用的服务电子邮件帐户具有编辑权限，我也试过提供视图访问权限。我在这里还有什么错。请帮忙。
