您没有提到如何获得base64。为了重现，我的代码片段使用了
requests库从互联网上获取图像，然后使用库将其转换为base64
base64。
这里的技巧是确保要上传的base64字符串不包含
data:image/jpeg;base64前缀。而且，正如评论中提到的@dmigo一样，您应该使用
boto3.resource
而不是boto3.client。
from botocore.vendored import requests import base64 import boto3 s3 = boto3.resource('s3') bucket_name = 'BukcetName' #where the file will be uploaded, if you want to upload the file to folder use 'Folder Name/FileName.jpeg' file_name_with_extention = 'FileName.jpeg' url_to_download = 'URL' #make sure there is no data:image/jpeg;base64 in the string that returns def get_as_base64(url): return base64.b64enpre(requests.get(url).content) def lambda_handler(event, context): image_base64 = get_as_base64(url_to_download) obj = s3.Object(bucket_name,file_name_with_extention) obj.put(Body=base64.b64depre(image_base64)) #get bucket location location = boto3.client('s3').get_bucket_location(Bucket=bucket_name)['LocationConstraint'] #get object url object_url = "https://%s.s3-%s.amazonaws.com/%s" % (bucket_name,location, file_name_with_extention) print(object_url)有关S3.Object.put的更多信息。
