我想制作300个Google文档文件。
所以我找到了google docs api，但对我不起作用。
这是我的出处和错误。
请帮助我。

Private static final list <String> SCOPES = Collections.singletonList (DocsScopes).DOCUMENTS);我认为这条线是错误的。最初是DOCUMENTS_READONLY，但没有用，因此被更改了。如果您能给我解决方案，我将不胜感激。
您有该错误，因为即使使用正确的作用域（DocsScopes.DOCUMENTS），也必须删除StoredCredential文件（位于tokens文件夹中）才能刷新授权信息。通过再次执行Oauth流程，将以这种方式设置新范围。
除非由于Docs API Quotas状态而采取一些预防措施，否则您将无法在一次运行中创建300个文档：
