通过 boto3“MalformedPolicy 错误”将公共访问策略附加到 S3 存储桶不断抬头

Question

import boto3
import json

S3API = boto3.client("s3", region_name="regionname") 
bucket_name = "bucketname"

policy_file = open("../public_policy.json", "r")


S3API.put_bucket_policy(
    Bucket = 'bucket_name',
    Policy = 'policy_file.read()'
)


botocore.exceptions.ClientError: An error occurred (MalformedPolicy) when calling the PutBucketPolicy operation: Policies must be valid JSON and the first byte must be '{'

Answer 1

Your policy is literal string "policy_file.read()" . It should be (assuming the policy file is correct):

S3API.put_bucket_policy(
    Bucket = bucket_name,
    Policy = policy_file.read()
)
