java - 您的应用程序已使用来自 Google Cloud SDK 的最终用户凭据进行身份验证，而 translate.googleapis.com 不支持这些凭据

Question

看完类似的问题，比如:

i am using gcp service account but when calling dialogue flow api its giving error :

和

Why is Google Cloud API trying to connect as an end-user?

并应用建议的解决方案我仍然收到错误:

Answer 1

此错误消息是由您在设置 Cloud SDK 时使用用户凭据引起的。通常，这是使用命令 gcloud auth login 完成的。

有几种方法可以解决这个问题。每种方法都使用一个服务帐户。

方法一:

创建服务帐号并设置 Cloud SDK 以使用该服务帐号。

示例命令:

gcloud auth activate-service-account test@development-123456.iam.gserviceaccount.com --key-file=/fullpath/service-account.json

方法 2:

将环境变量 GOOGLE_APPLICATION_CREDENTIALS 设置为指向您的服务帐户 JSON 文件。
set GOOGLE_APPLICATION_CREDENTIALS=/fullpath/service-account.json
方法 3:

创建 Java SDK 客户端时指定服务帐户。
