从ASP.NET中使用Google Domain中的Google Drive API时出错401

I am currently trying to add functionality to our company's ASP.NET website which will allow end users to upload files generated from the website into their own Google Drive (within the same company).

我目前正在尝试为我们公司的ASP.NET网站添加功能,这将允许最终用户将从网站生成的文件上传到他们自己的Google云端硬盘(在同一家公司内)。

The company has it's own Google Domain which includes Mail, Drive, Contacts, Calendar (and pretty much everything else). It uses SAML to authenticate with our Active Directory set up which links in to Google.

该公司拥有自己的Google Domain,其中包括Mail,Drive,Contacts,Calendar(以及其他所有内容)。它使用SAML通过我们的Active Directory设置进行身份验证,该设置链接到Google。

It should be noted that this code works OK with my @gmail.com account. With the companies Google App Domain account, I get the invalid credentials error (shown at the bottom). I have spoken with our Google Admin who claims that I have no restrictions on my account with regards to Drive API access. Please also bear in mind that the API ID/Secret's were created with my company account rather than a Gmail account.

应该注意的是,此代码可以与我的@ gmail.com帐户一起使用。使用Google App Domain公司的帐户,我收到了无效的凭据错误(显示在底部)。我与我们的Google管理员进行了交谈,他声称我的帐户对Drive API访问没有任何限制。另请注意,API ID / Secret是使用我的公司帐户而非Gmail帐户创建的。

问题发生在“request.Upload”行,出现以下异常。

Any help is much appreciated. Thanks.

Well, I figured out the root cause of the problem. It turns out that our company's Google Apps account had Docs API access turned off.

好吧,我找出了问题的根本原因。事实证明,我们公司的Google Apps帐户已关闭了Google文档API访问权限。

Our Google Apps Administrator has since turned it on and this has resolved the issue.

我们的Google Apps管理员已将其打开,这解决了这个问题。
