全局名称 's3' 未使用 boto 定义？

Question

Boto3 已安装，但当我尝试使用以下函数将图像上传到 S3 存储桶时，出现全局名称 's3' 未定义错误。

有没有我遗漏的东西？

import logging
import boto3
from botocore.exceptions import ClientError
import os

def upload_file(file_name, bucket, object_name=None):

if object_name is None:
    object_name = os.path.basename(file_name)

s3_client = boto3.resource('s3')

try:
    response = s3.client.upload_file(file_name, bucket, 
    object_name)
except ClientError as e:
    logging.error(e)
    return False
return True

upload = upload_file('test1.jpg','mybucket', 'test1.jpg')

Answer 1

这一行：

response = s3.client.upload_file(file_name, bucket, object_name)

应该是：

response = s3_client.upload_file(file_name, bucket, object_name)
