Amazon Rekognition：AccessDeniedException，用户无权执行：rekognition：DetectText

Question

我正在尝试使用文本检测并运行示例代码以了解其工作原理。 我的代码如下：

以字节格式传递图像的代码给出错误：

botocore.errorfactory.AccessDeniedException: An error occurred (AccessDeniedException) when calling the DetectText operation: User is not authorized to perform: rekognition:DetectText because no identity-based policy allows the rekognition:DetectText action

代码是：

from PIL import Image
import io
local='Dauntless.jpg'
client = boto3.client('rekognition', region_name='region name here',aws_access_key_id="keyId here",aws_secret_access_key="key here")
image = Image.open(local)

stream = io.BytesIO()
image.save(stream,format="JPEG")
image_binary = stream.getvalue()

response = client.detect_text(Image={'Bytes':image_binary})
print(response)

我尝试了另一个代码如下，它也返回相同的错误。

import boto3

def detect_text(photo, bucket):

    client=boto3.client('rekognition', region_name='name 'here ,aws_access_key_id="key here",aws_secret_access_key="key here")

    response=client.detect_text(Image={'S3Object':{'Bucket':bucket,'Name':photo}})

    textDetections=response['TextDetections']
    print ('Detected text\n----------')
    for text in textDetections:
            print ('Detected text:' + text['DetectedText'])
            print ('Confidence: ' + "{:.2f}".format(text['Confidence']) + "%")
            print ('Id: {}'.format(text['Id']))
            if 'ParentId' in text:
                print ('Parent Id: {}'.format(text['ParentId']))
            print ('Type:' + text['Type'])
            print()
    return len(textDetections)

def main():

    bucket='bucketname'
    photo='Dauntlessss_52a311a2-884a-4bcb-ba29-d705c5a2ea12.jpg'
    text_count=detect_text(photo,bucket)
    print("Text detected: " + str(text_count))


if __name__ == "__main__":
    main()

这两个代码都返回相同的错误。 关于我在这里缺少什么的任何帮助？ 我是 AWS 的新手。

未应用适当的策略/许可。

请正确阅读 Amazon Rekognition 基于身份的政策。 以下示例授予对 Amazon Rekognition 资源的完全访问权限。

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "rekognition:*"
                ],
                "Resource": "*"
            }
        ]
    }
