在GAE上用Java编写Cron作业来运行BigQuery [英] Write Cron Job in Java on GAE to Run BigQuery

问题描述

我想在GAE上运行一个内部调用BigQuery的cron作业。

我目前能够运行BigQuery，但我需要使用我的凭据登录。但是我想在没有任何登录的情况下为BigQuery运行cron作业。

任何帮助都将不胜感激。

$ $ p> private static final HttpTransport TRANSPORT = new NetHttpTransport（）;
private static final JsonFactory JSON_FACTORY = new JacksonFactory（）;
private static Bigquery bigquery;




AppIdentityCredential凭证=新的AppIdentityCredential（Collections.singleton（BigqueryScopes.BIGQUERY））;
bigquery = new Bigquery.Builder（TRANSPORT，JSON_FACTORY，凭证）
.setApplicationName（BigQuery-Service-Accounts / 0.1）
.setHttpRequestInitializer（凭证）.build（）;


I want to run a cron job on GAE that internally calls BigQuery.

I am currently able to run BigQuery but I need to log in with my credentials. But I would like to run the cron job for BigQuery without any login.

Any help would be highly appreciated.

解决方案

I am successfully able to implement it in java.Before performing it we need to generate client id for service account.

private static final HttpTransport TRANSPORT = new NetHttpTransport();
private static final JsonFactory JSON_FACTORY = new JacksonFactory();
private static Bigquery bigquery;




AppIdentityCredential credential = new AppIdentityCredential(Collections.singleton(BigqueryScopes.BIGQUERY));
bigquery = new Bigquery.Builder(TRANSPORT, JSON_FACTORY, credential)
            .setApplicationName("BigQuery-Service-Accounts/0.1")
            .setHttpRequestInitializer(credential).build();
