如何以编程方式为 python SDK 设置项目？

Question

我不想使用 gcloud cli 或环境变量设置项目，我想以编程方式执行此操作。我正在尝试使用 client_options，但这不起作用：

from google.cloud import translate_v2 as translate

def translate_text(target: str, text: str):
    translate_client = translate.Client(
         client_options={
             "quota_project_id": "my-proj-id",
         }
    )
    ...

我收到错误：

Cloud Translation API has not been used in project <A DIFFERENT PROJECT>

。

如何在构造函数中将其设置为特定项目？

编辑

我找到了同一 API 的另一个代码示例（令人烦恼的是，我知道其中的区别是什么以及我应该使用哪一个）。

但这也不起作用，当我全局设置时它会起作用：

gcloud auth application-default set-quota-project my-project

，但我不想这样做。我无法在运行此容器化应用程序的地方运行 gcloud。

# Imports the Google Cloud Translation library
from google.cloud import translate


# Initialize Translation client
def translate_text(
    text: str = "YOUR_TEXT_TO_TRANSLATE", project_id: str = "YOUR_PROJECT_ID"
) -> translate.TranslationServiceClient:
    """Translating Text."""

    client = translate.TranslationServiceClient(
        client_options={
            "quota_project_id": "my-proj",
        }
    )

    location = "global"

    parent = f"projects/{project_id}/locations/{location}"

    # Translate text from English to French
    # Detail on supported types can be found here:
    # https://cloud.google.com/translate/docs/supported-formats
    request = {
        "parent": parent,
        "contents": [text],
        "mime_type": "text/plain",  # mime types: text/plain, text/html
        "source_language_code": "en-US",
        "target_language_code": "fr",
    }

    response = client.translate_text(**request)

    # Display the translation for each input text provided
    for translation in response.translations:
        print(f"Translated text: {translation.translated_text}")

    return response


translate_text("hello", "my-proj")

我得到：

google.api_core.exceptions.PermissionDenied: 403 Cloud Translation API has not been used in project <MY SERVICE ACCOUNTS PROJECT> before or it is disabled.

此 GSA 与启用了 API 的项目位于不同的项目中，我无法更改这一点。我现在可以使用 gcloud cli，如何在代码中执行此操作？

Answer 1

这是我让它发挥作用的唯一方法。我发誓其他客户让设置项目变得很容易，所以我猜可能只是这个 api 或者我正在使用旧的库版本或其他东西。

也许我应该使用发现 API 并通过它构建客户端？但我找不到例子。

此外，还有很多可怕的错误，导致解决这个问题所需的时间比应有的时间要长。如果服务帐户根本没有项目的权限，我会收到此错误，这是错误的，非常荒谬：

google.api_core.exceptions.InvalidArgument：400 无效的“父级”。； 资源名称项目 ID 无效。标识符必须仅包含 小写字母、数字、句点、冒号或连字符。；资源 类型：位置

    # Manually build creds with quota_project_id set
    credentials, _ = google.auth.default(quota_project_id=project_id)

    client = translate.TranslationServiceClient(
