Question

我正在尝试为我的项目获取GoogleCredential，如下所示，

GoogleCredential credential = new GoogleCredential.Builder()
                     .setTransport(httpTransport)
                     .setJsonFactory(jsonFactory)
                     .setServiceAccountId("xxx@famous-store-115417.iam.gserviceaccount.com")
                     .setServiceAccountScopes(SCOPES)
                     .setServiceAccountPrivateKeyFromP12File(new File(p12))
                     .build();

但我收到了错误，

  "error" : "invalid_grant"

我知道它的权限相关错误，但我使用了正确的密钥和服务帐户ID，我也通过网络搜索了它，但它与建议的解决方案相同。我也审核了this。

任何建议都表示赞赏，提前谢谢。我应该缺少什么？

最后我发现解决方案是，

我使用的是Goodle Drive API，因此我需要与服务帐户（xxx@famous-store-115417.iam.gserviceaccount.com）共享该文档。之后它正常运作。

我希望对别人有帮助。
