[英]how to use offical google translate api on local runtime via python
after reading the offical google translate api document, it provide us with the following sample code:在阅读了官方的谷歌翻译 api 文档后,它为我们提供了以下示例代码:
from google.cloud import translate
def translate_text(text="Hello, world!", project_id="weighty-site-333613"):
client = translate.TranslationServiceClient().from_service_account_json('key.json')
location = "global"
parent = f"projects/{project_id}/locations/{location}"
response = client.translate_text(
request={
"parent": parent,
"contents": [text],
"mime_type": "text/plain",
"source_language_code": "en-US",
"target_language_code": "zh-CN",
}
)
for translation in response.translations:
print("Translated text: {}".format(translation.translated_text))
translate_text()
These code worked properly on google cloud terminal.这些代码在谷歌云终端上正常工作。 However, even if i put the "key.json" file in the same folder, an error like this is shown:
但是,即使我将“key.json”文件放在同一个文件夹中,也会显示如下错误:

You need service account json file with correct permissions from GCP under IAM & Service Accounts.您需要服务帐户 json 文件,该文件在 IAM 和服务帐户下具有来自 GCP 的正确权限。
Then you need to implement command,然后你需要执行命令,
GOOGLE_APPLICATION_CREDENTIALS = "/path/to/your/service_account.json"
