Question

我对Python很陌生。我正在尝试使用Amazon Polly Text to speech模块。我已经在Windows 10上运行了这个。已经阅读了亚马逊文档，但我现在很丢失..抱歉，我的英语不是很好。

我的代码如下。

    """Getting Started Example for Python 2.7+/3.3+"""
from boto3 import Session

from botocore.exceptions import BotoCoreError, ClientError

from contextlib import closing
import os
import sys
import subprocess
from tempfile import gettempdir
# Create a client using the credentials and region defined in the [adminuser]
# section of the AWS credentials file (~/.aws/credentials).
session = Session(profile_name="adminuser")
polly = session.client("polly")
try:
 # Request speech synthesis
    response = polly.synthesize_speech(Text="Hello world!", OutputFormat="mp3",
    VoiceId="Joanna")
except (BotoCoreError, ClientError) as error:
 # The service returned an error, exit gracefully
    print(error)
    sys.exit(-1)
# Access the audio stream from the response
if "AudioStream" in response:
 # Note: Closing the stream is important as the service throttles on the
 # number of parallel connections. Here we are using contextlib.closing to
 # ensure the close method of the stream object will be called automatically
 # at the end of the with statement's scope.
    with closing(response["AudioStream"]) as stream:
        output = os.path.join(gettempdir(), "speech.mp3")
    try:
         # Open a file for writing the output as a binary stream
         with open(output, "wb") as file:
             file.write(stream.read())
    except IOError as error:
         print(error)
         sys.exit(-1)
else:
 # The response didn't contain audio data, exit gracefully
    print("Could not stream audio")
    sys.exit(-1)
# Play the audio using the platform's default player
if sys.platform == "win32":
    os.startfile(output)
else:
 # the following works on Mac and Linux. (Darwin = mac, xdg-open = linux).
    opener = "open" if sys.platform == "darwin" else "xdg-open"
    subprocess.call([opener, output])

我在这里有我的凭据文件。（编辑这样，它不是真正的凭据）。在同一文件夹中，它将另存为配置。我也在同一个文件夹中制作了名为config和boto.config的副本，希望我的名字错了。但无济于事。

[Credentials]
aws_access_key_id = AKIAIO4GAFVCGZMTZ6WQ
aws_secret_access_key = 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

[adminuser]
aws_access_key_id = AKIAIO4GAFVCGZMTZ6WQ
aws_secret_access_key = /7KVymkCQbGKI5/E1ifdafsuVCciwOd1WiIImxA

这是我收到的错误消息。

    raise ProfileNotFound(profile=profile_name)

那里有专家告诉我应该做些什么？

Answer 1

您应该设置{ "variables": { "aws_access_key": "", "aws_secret_key": "", "aws_profile": "test-dev" }, "builders": [{ "type": "amazon-ebs", "access_key": "{{user `aws_access_key`}}", "secret_key": "{{user `aws_secret_key`}}", "region": "us-east-2", "profile": "{{user `profile`}}", "source_ami": "ami-336b4456", "instance_type": "t2.micro", "ssh_username": "ubuntu", "ami_name": "packer-example {{timestamp}}" }], "provisioners": [{ "type": "shell", "execute_command": "sudo -S bash '{{.Path}}'", "script": "provision1.sh" }]`

~/.aws/config

Answer 2

Boto3查找.aws / credentials文件或.boto.config文件以进行身份验证。在Windows机器上，您需要创建一个名为credentials。或.boto.config的文件，并将文件保存在此位置C：\ Users \ USERNAME .aws \ credentials。

文件内容为

[adminuser]
aws_access_key_id = AKIAIO4GAFVCGZMTZ6WQ
aws_secret_access_key = /7KVymkCQbGKI5/E1ifdafsuVCciwOd1WiIImxA
