google-bigquery - 使用服务帐户的 Google Bigquery 401 未经授权的错误

Question

当我尝试来自 this post 的 Michael 的 bigquery 片段时遇到了“401 Unauthorized”问题在我的电脑上。根据 ryguyrg 的建议，我同步了我的计算机时间(通过单击“立即更新”)并且代码工作。但问题是，一段时间后，也许几分钟后，当我重新运行代码时，它再次失败并出现 401 错误。所以几乎每次我想运行大查询请求时，我都必须手动同步我的计算机时间。

我很确定我的计算机运行良好，并且时间与服务器的差异不应超过几毫秒。那么究竟是什么导致了这个问题呢？我应该尝试在请求之前从代码中同步时间还是有更好的方法？

下面是401错误信息供引用:

Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized

在这个例子中我遇到了同样的问题。 https://cloud.google.com/bigquery/docs/quickstarts/quickstart-client-libraries

我试图执行以下命令，但发生 401 错误

导出 GOOGLE_APPLICATION_CREDENTIALS=/Users/mattheu/credentialFileName.json

我使用下面解决了凭据问题

String jsonPath = "/Users/mattheu/credentialFileName.json";
        GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream(jsonPath));

package com;

import com.google.auth.oauth2.GoogleCredentials;
import com.google.cloud.bigquery.*;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.UUID;

public class App {
    public static void main(String[] args) throws InterruptedException, IOException {
        String jsonPath = "/Users/mattheu/credentialFileName.json";
        GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream(jsonPath));

        BigQuery bigquery = BigQueryOptions.newBuilder()
                .setCredentials(credentials)
                .build().getService();

        QueryJobConfiguration queryConfig =
                QueryJobConfiguration.newBuilder(
                        "SELECT "
                                + "CONCAT('https://stackoverflow.com/questions/', CAST(id as STRING)) as url, "
                                + "view_count "
                                + "FROM `bigquery-public-data.stackoverflow.posts_questions` "
                                + "WHERE tags like '%google-bigquery%' "
                                + "ORDER BY favorite_count DESC LIMIT 10")
                        // Use standard SQL syntax for queries.
                        // See: https://cloud.google.com/bigquery/sql-reference/
                        .setUseLegacySql(false)
                        .build();

        // Create a job ID so that we can safely retry.
        JobId jobId = JobId.of(UUID.randomUUID().toString());
        Job queryJob = bigquery.create(JobInfo.newBuilder(queryConfig).setJobId(jobId).build());

        // Wait for the query to complete.
        queryJob = queryJob.waitFor();

        // Check for errors
        if (queryJob == null) {
            throw new RuntimeException("Job no longer exists");
        } else if (queryJob.getStatus().getError() != null) {
            // You can also look at queryJob.getStatus().getExecutionErrors() for all
            // errors, not just the latest one.
            throw new RuntimeException(queryJob.getStatus().getError().toString());
        }

        QueryResponse response = bigquery.getQueryResults(jobId);

        TableResult result = queryJob.getQueryResults();

        // Print all pages of the results.
        for (FieldValueList row : result.iterateAll()) {
            String url = row.get("url").getStringValue();
            long viewCount = row.get("view_count").getLongValue();
            System.out.printf("url: %s views: %d%n", url, viewCount);
        }
    }
}
