Question

我正在使用带有谷歌云语音api的python我在ubuntu和Windows上的“How to use google speech recognition api in python?”中执行了所有步骤，当我尝试从这里运行简单脚本时 - “{{3} }“

我收到下一个错误： <HttpError 403 when requesting https://speech.googleapis.com/$discovery/rest?version=v1beta1 returned "Google Cloud Speech API has not been used in project google.com:cloudsdktool before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/speech.googleapis.com/overview?project=google.com:cloudsdktool then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.">

奇怪的是，我没有名为“cloudsdktool”的项目

我运行“gcloud init”，并将我在创建服务帐户密钥时获得的json文件与“gcloud auth activate-service-account --key-file = jsonfile”命令相关联，我尝试在linux中创建谷歌凭证环境变量，我仍然得到相同的按摩

所以我找到了两种方法来解决这个问题：

1 - 如果使用google cloud sdk并且云语音处于测试版，则需要运行“gcloud beta init＆＃39;而不是＆＃; gcloud init＆＃39;然后提供json文件

2 - 如果您不想使用谷歌的云sdk，您可以直接在python应用程序中传递json文件

这是方法：

from oauth2client.client import GoogleCredentials

GoogleCredentials.from_stream('path/to/your/json')

然后你只需要在信任和授权上创建范围，或者如果使用grpc（流媒体），你将它传递给标题就像在示例中一样。

这是更改的grpc脚本：

def make_channel(host, port):
    """Creates an SSL channel with auth credentials from the environment."""
    # In order to make an https call, use an ssl channel with defaults
    ssl_channel = implementations.ssl_channel_credentials(None, None, None)

    # Grab application default credentials from the environment
    creds = GoogleCredentials.from_stream('path/to/your/json').create_scoped([SPEECH_SCOPE])
    # Add a plugin to inject the creds into the header
    auth_header = (
        'Authorization',
        'Bearer ' + creds.get_access_token().access_token)
    auth_plugin = implementations.metadata_call_credentials(
        lambda _, cb: cb([auth_header], None),
        name='google_creds')

    # compose the two together for both ssl and google auth
    composite_channel = implementations.composite_channel_credentials(
        ssl_channel, auth_plugin)

    return implementations.secure_channel(host, port, composite_channel)

谷歌云语音api在尝试使用时抛出403
