Amazon Polly ProfileNotFound:找不到配置文件(管理员用户)

Question

我对Python非常陌生。我正在试用Amazon Polly Text to speech模块。我在Windows10上运行这个程序。我已经阅读了amazon文档，但我现在完全迷失了方向。对不起，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])

我这里有我的证件文件。(对此进行了编辑，使其不是真正的凭证)。在相同的文件夹中，它被保存为配置。我还在同一个文件夹中复制了名为config和boto.config的文件，希望我把名字弄错了。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

这是我得到的错误消息。

有没有专家能告诉我该怎么做呢？

Answer 1

您应该在~/.aws/config中进行设置

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

Answer 2

Boto3查找.aws/credentials文件或.boto.config文件进行身份验证。在windows机器上，您需要创建一个名为credentials或.boto.config的文件，并将该文件保存在位置C:\Users\USERNAME .aws\credentials。

文件内容将为

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