Python 的语音转文本 API v2 问题（权限被拒绝）

问题描述 投票：0回答：1

只能在 Google Shell 中使用路径设置命令“exports...”。不要在代码中和我的主平台 Python Local 上使用“PATH”在 shell 中工作

在一个涉及 Google 语音转文本 API（特别是较新的 v2 版本）的项目中，我面临着从 PHP 过渡到 Python 的令人困惑的问题。我之前使用 API 版本 1 在 PHP 中成功实现了一个项目。然而，在迁移到 Python 以更好地与 v2 API 和 Google 文档保持一致时，我遇到了权限问题。

-核心问题：

在 PHP 中，一切都顺利进行，但在 Python 中，我遇到了与peer.recognizers.recognize 权限相关的 PermissionDenied 错误。这很令人困惑，因为相同的项目和服务帐户在 PHP 中运行良好。

-代码片段（Python）：

import os
from google.cloud.speech_v2 import SpeechClient
from google.cloud.speech_v2.types import cloud_speech

credential_path = "C:\\Users\\Joffrey-PTMG\\Desktop\\U23\\OFC-SUBM2.0\\authgooglejson\\hidekey.json"
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = credential_path

def transcribe_file_v2(
    project_id: str,
    audio_file: str,
) -> cloud_speech.RecognizeResponse:
    
    print(project_id)
    # Instantiates a client
    client = SpeechClient()

    # Reads a file as bytes
    with open(audio_file, "rb") as f:
        content = f.read()

    config = cloud_speech.RecognitionConfig(
        auto_decoding_config=cloud_speech.AutoDetectDecodingConfig(),
        language_codes=["fr-FR"],
        model="long",
    )

    request = cloud_speech.RecognizeRequest(
        recognizer=f"projects/{project_id}/locations/global/recognizers/_",
        config=config,
        content=content,
    )

    # Transcribes the audio into text
    response = client.recognize(request=request)

    for result in response.results:
        print(f"Transcript: {result.alternatives[0].transcript}")

    return response

project_idvar = 'eighth-server-267708'
audio_filevar = 'testtt.mp3'

transcribe_file_v2(project_idvar, audio_filevar)

我一直在尝试直接通过 Google Cloud Shell 运行我的 Python 脚本。有趣的是，环境变量 PATH 的工作方式并不像我的 PHP 项目那样无缝。因此，我在 Python 脚本中添加了以下几行来设置凭据路径：

credential_path = "C:\\Users\\Joffrey-PTMG\\Desktop\\U23\\OFC-SUBM2.0\\authgooglejson\\hidekey.json"
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = credential_path

这是为了让它工作，但即使删除这些行并尝试使用以下方法通过 Cloud Shell 设置环境变量：

export GOOGLE_APPLICATION_CREDENTIALS='/home/vedlem_mail/jsonss/hidekey.json'

我遇到了同样的错误。所以在我看来，这些行并不是问题的根源，但我们现在不知道为什么..

没有定义路径的行但执行了导出行的版本仅适用于 google shell（可能要感谢 shell 的重新启动）

我的目标是简单地在 .mp3 文件上使用语音转文本。我正在尝试克服看似虚假的错误，因为我在角色设置中被指定为“所有者”。这个设置在 PHP 中完美运行，所以我不明白为什么它在 Python 中不起作用。

帮助我🙏😢谢谢

我遇到了同样的问题，发现语音 v2 需要服务代理。 https://cloud.google.com/iam/docs/service-agents 搜索语音，然后使用 GCP 命令创建它。

gcloud beta services identity create --service=speech.googleapis.com --project=<Your project name here>

project_number=$(gcloud projects list --filter=<Your project name here> --format="value(PROJECT_NUMBER)")

gcloud projects add-iam-policy-binding neos-stt-0 --member serviceAccount:service-${project_number?}@gcp-sa-speech.iam.gserviceaccount.com --role roles/speech.serviceAgent
