获取编码基64 显示数据的最佳途径是把数据储存在3号元文档中。
原标题:What is the best way to get encoded base64 string data that is stored in s3 as png files

我有3条道路,包括S3的p纳克/jpeg图像。 我想在平时将这种图像转换成基64。 似乎我可以做的是,我可以尝试下载图像并将其编成基64。 我很想知道,使用boto3获取编码图像的方法是否更好,因为我实际上不需要下载。

此外,能否使用三条带boto3的通道? 根据我的研究,似乎是不可能的,因此,我们需要分清获得 b子和物体名称的道路。

问题回答

由于编码为真切需要<代码>boto3 需要这样做,它并没有提出这种选择。 您仅能对飞行内容进行编码:

import base64
import io
import boto3


class Base64Encoder(io.IOBase):
    def __init__(self, fileobj):
        self.fileobj = fileobj

    def write(self, b):
        return self.fileobj.write(base64.b64encode(b))


# some code that sets things up
...
s3 = boto3.client( s3 )

# download from S3, encode to base64 on the fly, and write to wherever you need it
with whatever_gets_your_file_like_target() as f:
    s3.download_fileobj( mybucket ,  mykey , Base64Encoder(f))

由于你没有提供信息,说明你实际上需要写上该基准64的编码内容,因此,我只打上whatever_gets_your_file_ similar_target(
