无法使用python将JSON文件从google云存储加载到bigquery

from google.cloud import bigquery
from google.cloud import storage

# 设置Cloud Storage和BigQuery的凭据和项目ID
storage_client = storage.Client()
bigquery_client = bigquery.Client()

# 指定Cloud Storage中的JSON文件路径
bucket_name = 'your_bucket_name'
file_name = 'your_file_name.json'
blob = storage_client.bucket(bucket_name).blob(file_name)

# 指定BigQuery中的目标数据集和表
dataset_id = 'your_dataset_id'
table_id = 'your_table_id'

# 定义数据加载配置
job_config = bigquery.LoadJobConfig()
job_config.source_format = bigquery.SourceFormat.NEWLINE_DELIMITED_JSON
job_config.autodetect = True

# 执行数据加载操作
load_job = bigquery_client.load_table_from_uri(
    blob.uri, dataset_id + '.' + table_id, job_config=job_config
)

# 等待数据加载完成
load_job.result()

# 输出加载结果
print('Data loaded successfully into BigQuery table.')
