python - AWS S3 写入对象 - TypeError：预期的字符串或类似字节的对象

问题描述

我正在尝试使用 boto3 将一个简单的 txt 文件写入 S3。无论我做什么，都会抛出同样的错误。变量“msg”是一个字符串。理论上它应该被接受，但它没有工作。所以我对其进行了编码，仍然无法正常工作。有任何想法吗？TIA

report = s3.Object(bucket, reportfilename)
byte_msg=bytes(msg, 'utf-8')
s3put = report.put(Body=byte_msg)

Traceback (most recent call last):

解决方案

错误在块中抛出if not VALID_BUCKET.search(bucket) and not VALID_S3_ARN.search(bucket)

根据docs， s3.Object 构造函数接受bucket_name(string) 和key(string) 作为参数。确保您将存储桶名称作为字符串而不是作为 Bucket 对象传递。
