Google 日历 API 是否支持"无需 OAuth 的服务帐号授权"方法？

Question

我正在尝试使用不带OAuth的方法来访问Calendar API，从而为服务帐户实现授权。https://developers.google.com/identity/protocols/oauth2/service-account#jwt-授权

With some Google APIs, you can make authorized API calls using a signed JWT directly as a bearer token, rather than an OAuth 2.0 access token.
If the API you want to call has a service definition published in the Google APIs GitHub repository, you can make authorized API calls using a JWT instead of an access token. To do so:
Using any standard JWT library, such as one found at jwt.io, create a JWT with a header and payload like the following example:

{
"alg": "RS256",
"typ": "JWT",
"kid": "abcdef1234567890"
}
.
{
"iss": "[e-mail]",
"sub": "[e-mail]",
"aud": "https://firestore.googleapis.com/",
"iat": 1511900000,
"exp": 1511903600
}

上述文件提到JWTaud字段应以https://SERVICE.googleapis.com/格式给出。由于日历端点不在格式中，是否可以使用此授权机制访问日历API？

日历端点为https://www.googleapis.com/

Answer 1

是。Google提供日历服务API端点作为https://calendar-json.googleapis.com/。https://support.google.com/workspacemigrate/answer/9222865?hl=en
